Penn State Webinar: H-2A Agricultural Workers in Times of Uncertainty

Penn State Cooperative Extension is hosting a free webinar to discuss the H-2A program in Pennsylvania. This may be helpful for NJ Farmers to listen in to find any updates or tips on how to handle this agricultural worker program. You must register to join this online event. In order to register you will need to create an account on the Penn State advertisement page.

Webinar Date: Thu., May 7, 2020
(6:30 PM – 8:00 PM ET)

Registration deadline: May 7, 2020
5:30 p.m.

COVID-19 mitigation efforts, including international travel restrictions and consulate closures, have disrupted the normal functioning of the H-2A visa program for temporary workers. These disruptions to the H-2A program raise questions about the timely arrival of guest workers and the impact on essential food and agricultural businesses. The H-2A Agricultural Workers in Times of Uncertainty Webinar will provide answers and guidance to the many questions surrounding this topic.
The dangers of COVID-19 itself similarly raises questions around how to protect the health and well-being of H-2A visa holders. As front-line workers, the protection of their livelihoods and health are integrally tied to the protection of public health.

Penn State Extension will be holding a townhall-style webinar to address these topics, and to provide answers and guidance to these questions. Join us as we hear from a panel of subject matter experts, including Brook Duer, Staff Attorney at the Penn State Center for Agricultural and Shale Law; Grant Meckley, Pennsylvania Keystone Health’s Agricultural Worker Program; Scott Sheely, Executive Director of the Lancaster County Agriculture Council; and Richard Stup, Agricultural Workforce Specialist at Cornell Cooperative Extension. Also joining us will be Alyssa Charney, Agriculture Legislative Assistant from Senator Casey’s Office.

Attendees will have the opportunity to either send in questions ahead of time, or during the webinar itself, for a Q&A session following the panelists’ overview and update on the H-2A visa program.

There is no cost for this webinar, however registration is required to receive the webinar link. To go to the registration page you can also see https://go.rutgers.edu/if9tsm4h.

Dealing with Stress on the Farm During Trying Times

This is a stressful time for many people in our country and especially on the farm. With constant updates from government officials and media sharing new about the pandemic and the fear of the unknown for the future, it is understandable to feel overwhelmed, stressed and anxious. Seeing other farmers around the nation struggling with crop losses and distribution nightmares makes other farmers wonder what is yet to come. You are not alone and there are resources to help if you are struggling with stress and anxiety.

For assistance contact the Substance Abuse and Mental Health Services Administration’s (SAMHSA) Disaster Distress Helpline at 800-985-5990, the National Suicide Prevention Lifeline at 800-273-8255 or text MHFA to 741741 to talk to a Crisis Text Line counselor.

Farmers often feel they may be mentally and physically tougher than most people. That may be true. However, it is understandable if you are feeling depressed or anxious right now, just like the millions of people across the country who are facing the same worries and challenges. It’s perfectly understandable since most people have never experienced times like we are facing now. It’s extremely important to take care of your mental health. Helping yourself means you will be able to help others in the future.

While times may not change as quickly as we would like, there are easy self-care strategies that can help reduce feelings of depression and anxiety, or prevent anxiety before it even starts.

Here are some tips that may help:
1. Eat healthy foods to keep your body in top working order and avoid foods/beverages that cause issues with underlying health conditions.
2. Exercise reduces symptoms of depression and anxiety. Exercise is not the same as regular activity at work. Take a brisk walk or jog down a farm road, ride a bike, lift weights (even if you need to make your own out of what you have around the farm and start light).
3. Practice relaxation therapy. Focusing on tensing and relaxing muscle groups can help you relax voluntarily when feeling overwhelmed, stressed or anxious. Concentrate on the shoulder and neck regions of the body, where stress often builds.
4. Be kind to yourself. Treat yourself with the same compassion you would a friend and allow others to help as you would help them.
5. Stay connected. Even if you can’t get together face-to-face, you can stay connected to friends, family and neighbors with phone calls, text messages, video chats and social media. If you’re feeling lonely, sad or anxious, reach out to your social support networks – all is kept confidential. Share what you are feeling and offer to listen to friends or family members about their feelings. We are all experiencing this scary and uncPerson holding a fishertain time together.
6. Monitor media consumption. While you might want to stay up-to the minute with COVID-19 news, too much exposure can be overwhelming. Balance media consumption with other activities you enjoy, such as playing with pets, reading, cooking, fishing at the farm pond, playing games with family or listening to music.

Adding small changes to your routine each day can make a big difference to your overall mood and well-being. Just remember, if you need help, help is available.

Chemical Alternative Options to Paraquat for Weed Control in Vegetable Crops

Spraying for pests in a field Paraquat is an herbicide labeled on various crops species for row middles applications. However, with new paraquat use restrictions in place, vegetable growers may be interested by other herbicide options available for controlling emerged weed seedlings. Paraquat controls numerous annual grasses and broadleaf weeds seedlings by inhibiting plant photosynthesis. Its acts quickly by contact when absorbed by plant foliage and has no soil activity due to complete soil adsorption. Because of poor translocation, it is essential to have complete foliar coverage to achieve good weed control. Hence, the need for a non-ionic surfactant and the importance of making sure that weeds are not taller than 6” when direct-spraying paraquat in row middles. Paraquat offers relatively good crop safety because it does not translocate and will control a wide range of annual weeds at the seedling stage, which makes it the herbicide of choice for postemergence row middles weed control in labeled crops.

However, paraquat high toxicity to humans either through ingestion, breathing, or simple dermal contact justifies its “Restricted Use Pesticide” classification and the implementation of new EPA regulations since November 2019 (https://plant-pest-advisory.rutgers.edu/gramoxone-paraquat-mandatory-training-required-before-use/)

Chemical alternatives to paraquat are available for vegetable growers but may not provide a similar level of weed control or can have more detrimental effects when contacting the crop because of their systemic activity. All the alternative options presented in this post are classified by WSSA Group Numbers which are based on herbicide site of actions within the plants. All recommendations provided here are strictly limited to shielded row middle applications. Consult label for approved surfactants, application restrictions, pre-harvest intervals, and crop rotation restrictions. The mention of trade names and rates is for educational purposes and does not imply endorsement by the author or the New Jersey Agricultural Experiment Station. Always defer to the product label for instructions on properly applying an herbicide.

5 Special Local Need label approved for New Jersey and expiring on Dec. 31, 2021

Group 2 – Inhibition of amino acids biosythesis

Sandea (halosulfuron), League (imazosulfuron), and Solida (rimsulfuron) have both preemergence and postemergence activity. These herbicides will control emerged seedlings of galinsoga, pigweeds, and ragweed, and suppress yellow nutsedge. League has shown good suppressive activity of common purslane. However, they are weak on common groundsel, common lambsquarters, eastern black nightshade. Sandea and League have little to no activity on grasses whereas Solida will have fair activity on crabgrass, barnyardgrass, and foxtail, but not on goosegrass or fall panicum. Thus, these herbicides should always be tank mixed with an herbicide partner for broadening their weed control spectrum. These herbicides have systemic activity and contact with the planted crop should always be avoided. Postemergence activity will be achieved if targeted weeds are no taller than 3” tall and if the appropriate surfactant is added to the spray solution.

Group 4 – Plant growth regulators

Spur/Stinger (clopyralid) is a soil residual and postemergence herbicide that received a 24(c) Special Local Need label for use on strawberry in New Jersey. Label allows spring and post-harvest applications to control composites (thistle, ragweed, dandelion, groundsel, galinsoga) and leguminous (clover, vetch, mugwort) weeds. It has very little to no activity on other broadleaf weed as well as on grasses. Stinger should not be tank-mixed with any other herbicide or with a surfactant. Weedar 64 (2,4-D) is strictly a postemergence herbicide only labeled for use on asparagus and strawberry. Weedar is active on many annual and perennial broadleaf weeds but is weak on galinsoga and has no activity on grasses. Because of the risk of physical or volatility drift associated with growth regulator herbicides, Stinger, Spur or Weedar should never be applied if sensitive crops (cucurbits, eggplant, pepper, tomato) are planted nearby or if conditions (wind, inversion temperature, topography) favor drift.

Group 5 and 7 – Photosynthesis inhibitors

Metribuzin (metribuzin) is a soil residual and postemergence herbicide labeled for use on tomato that will primarily control broadleaf weeds no taller than 1”. Metribuzin provides good control of young seedlings of most broadleaf weeds, except for morningglories and nightshades. Metribuzin can be applied postemergence as a directed spray at least 2 weeks after transplanting and when tomato plants have reached the 5-leaf stage. injury. Lorox (linuron) is labeled for use on asparagus as a postemergence spray before the cutting season or immediately after cutting. Lorox will provide similar control to metribuzin on weeds no taller than 4”. Both Metribuzin and Lorox are providing poor control of grasses and should therefore be tank mixed with a graminicide if grass seedlings have already emerged. Contact with the planted crop should always be avoided to reduce the risk of herbicide injury.

Group 14 – Cell membrane disrupters

Aim (carfentrazone) is strictly a postemergence herbicides that acts by contact on many annual broadleaf weeds no taller than 3-4”. It has no activity on grasses and only poor to fair efficacy on cocklebur, jimsonweed, and common purslane. Complete foliar coverage is essential to achieve good weed control and will require mixing COC, MSO or a non-ionic surfactant. Reflex (fomesafen) received a 24(c) Special Local Need label for use on pumphin, watermelon, winter and summer squash. Reflex has both soil residual and postemergence activity. It will provide fair to good control of various broadleaf weeds, including galinsoga, pigweeds, jimsonweed, nightshads, ragweed, carpetweed and shepherd’s purse, but is weak on grasses. Row middle applications should be made prior to emergence or transplanting for pumpkin and squashes, but are allowed post-transplant for watermelon. Applications should always be made with a shielded sprayer to avoid crop injury.

Group 22 – Cell membrane disrupters

Reglone (diquat) is a postemergence non selective herbicides that belongs to paraquat herbicidal family but has a lower toxicity. Reglone received a 24(c) Special Local Need label for shielded applications in tomato row middles. Spray coverage is essential for optimum effectiveness and can be achieved by mixing a non-ionic surfactant to the spray solution. Reglone is expected to have a similar weed control spectrum than paraquat but local data are needed to confirm its efficacy, especially on grasses.

Group 27 – Pigment inhibitors

Callisto (mesotrione) has both soil residual and postemergence activity and is labeled on asparagus for banded application prior to soear emergence or after harvest. Callisto applied postemergence will provide excellent control of annual broadleaf weeds such as galinsoga, lambsquarters, morningglories, pigweeds, nightshades, or velvetleaf. Callisto is not effective for controlling grasses and only provide limited control of common purslane and common ragweed. Callisto can also help suppressing yellow nutsedge. Applications for controlling targeted weed seedlings should always include COC or a non-ionic surfactant in addition to ammonium sulfate for improving Callisto burndown effectiveness. Weeds should not be taller than 5″ for optimal control.

 

In summary, there are other chemical options that can replace paraquat for control of emerged weeds in row middles in vegetables. However, most of them will have a more restricted spectrum of weed control than paraquat and will require the growers to properly identify the weed species before deciding which postemergence herbicide they want to use. Most of these herbicides have little to no control of grasses and will therefore require mixing a postemergence grass herbicide such as clethodim or sethoxydim for controlling emerged grass seedlings. Finally, timing of application with regard to weed growth stage is more critical with alternative options than with paraquat, since most of these herbicides require weeds no taller than 3 to 4″, or even 1″ for some herbicides, for achieving proper control.

U-Pick Operation Guidelines under COVID-19

Harvesting cropsThe CDC, FDA and USDA have no reports at this time of human illnesses that suggest coronavirus can be transmitted by food or food packaging.
U-Pick operations are unique with customers going out into the field to do their own harvesting. This creates special situations for the grower and customer. How do you protect the customers, workers, and grower?

Questions to Ask Yourself
1. How many customers will you allow to pick at one time and how will you manage this?
2. Will you provide picking containers, or do you expect the customer to bring their own?
3. Will you provide harvest tools, or do you expect the customer to bring their own?
4. Where are your handwashing facilities located? Do you need to add more or change the locations?
5. How will you provide produce to those who are unable to enter your retail area or conduct U-Pick activities?
6. What areas will need frequent cleaning and sanitation (PDF)? What products will you use for this task?

Customer Notification Prior to Arriving
1. Use your social media site to inform potential customers how you are going to run your U-Pick operation with COVID-19.
2. Inform customers that they must maintain 6 ft social distance from other customers and employees.
3. Let them know that handwashing stations and hand sanitizers will be available when they arrive.
4. Encourage your customers to come alone. Leave family at home. Only someone picking should be in the field.
5. Let them know if you will provide picking containers or they need to bring their own.
6. Face coverings are required for customers. If a customer arrives without one, or refuses to wear one, they cannot enter retail and production areas. Alternative methods of obtaining produce should be made available to them.

Upon Customer Arrival
1. Encourage everyone to wash their hands prior to going into the field.
2. Inform customers where they can pick and how many people are allowed in the field at one time.
3. Direct customers to wear face coverings and to practice social distancing.

Handwashing
1. Have handwashing stations at several locations on the farm. These should be conveniently located. If the field is not next to the check out area have handwashing stations out in the field.
2. Everyone should wash their hands often for 20 seconds with soap and water.
3. This means as soon as customers come to the farm, if they stop to eat, when they use bathroom facilities, etc. If hand sanitizers are available customers should wash hands then apply hand sanitizers. The sanitizer should be at least 62% alcohol.
4. Post handwashing signage (PDF) in the appropriate language at each handwashing station.
5. Designate the responsibility of monitoring handwashing facility supplies (water, soap, paper towels) to an individual. Provide ample supplies for restocking.

Field Picking
1. There different ways to handle picking. The number of pickers can be restricted at any one time or pick every other row. Whichever system is used there needs to be someone in the field to enforce the rules.
2. Consider what you supply to the customer when they go into the U-Pick areas.
3. Harvest tools, containers, wagons, etc. Ensure that you can properly clean and sanitize these commonly touched surfaces.

Employees
1. Train all employees on proper handwashing and food safety.
2. In New Jersey, employers must provide face coverings and gloves for their employees.
3. Handwashing is critical when dealing with customers (see above).
4. Hand sanitizers should be used between each customer by employees at checkout.
5. Touchpads should be sanitized between payment uses.
6. One person should handle money when checking out customers.

Understanding phenylamide (FRAC group 4) fungicides

The phenylamide fungicides (FRAC group 4) are a highly active class of fungicides that target oomycete pathogens such Phytophthora and Pythium spp. FRAC group 4 fungicides are also highly effective against downy mildew pathogens such as Pseudoperonospora cubensis (cucurbit downy mildew), Phytophthora infestans (Late blight), and basil downy mildew (Peronospora belbahrii) and many other important pathogens in vegetable production. Like other fungicide classes, FRAC group 4 fungicides have a high-risk for fungicide resistance development. The phenylamides (PA) inhibit ribosomal RNA (rRNA) biosynthesis in oomycete pathogens which inhibits several life stages in oomycetes including hyphal growth, haustoria and sporangia formation. The exact mechanism for resistance is not completely understood although research has shown that PA resistance is control by a single incompletely dominant gene although multiple mutations or mechanisms may be involved in PA resistance development. Pathogens such as cucurbit downy mildew, late blight, and basil downy mildew can be disseminated over vast geographic distances in any given year, thus this migration can be responsible for the introduction of new pathogen genotypes (including PA resistant) to new locations along with local selection pressure due to PA fungicide use resulting in changes in the pathogen population. Additionally, pathogens such as P. infestans and P. capsici (Phytophthora blight) are highly sexually active at the local level, because of the potential presence of two mating types (A1 and A2), you have a “recipe” that is always evolving. Resistance development to PA fungicides is often described as sensitive, intermediate, or resistant based on EC50  (Effective Concentration) values of the different fungicides needed to kill 50% of the pathogen in laboratory assays. This type of collected information is useful in determining what proportion of a given local, or wide geographic pathogen population, may be PA resistant. Recommended resistance management guidelines developed FRAC have not changed since 1997and are intended as general recommendations that must be adapted to respective pathosystems, fungicide use and patterns, and resistance levels.

The following are general recommendations for PA fungicide use as stated by FRAC.

  • PA fungicide should be used on a preventative basis; and not used as a curative or on a eradicative basis
  • As foliar applications, PA fungicide should always be tank mix with a unrelated fungicide from a different FRAC group
  • The total number of PA applications per season should be limited to 2 to 4 depending on label requirements
  • PA sprays are recommended for use earlier in the production season during active vegetative growth
  • PA should not be used as soil treatments against foliar disease development

Resistance development in P. capsici to mefenoxam has been known for many years in southern New Jersey. This is most likely to the widescale and overuse of mefenoxam in its early days because of the lack of an alternative chemistry, as well as a result of crop rotations where susceptible crops were planted in the same field for many years. In the past decade, there have been several new fungicides from different FRAC groups labeled for oomycete control. These include: Orondis Gold (oxathiapiprolin + mefenoxam, FRAC groups 49 + 4), Previcur Flex (propamocarb, 28), Ranman (cyazofamid, 21), Presidio (fluopicolide, 43), and Phosphites (33) for field use. Ranman, Previcur Flex, and phosphites have greenhouse use labels for Pythium control. Ranman and Previcur Flex can be applied in the transplant water.  Orondis Gold, mefenoxam, metalaxyl, and the phosphites are the most systemic of the group and should readily be taken up the by plant via application through the drip. Presidio has locally systemic and translaminar activity and offers protection of the root system via drip. Ranman has protectant-like activity and thus will offer root system protection. Growers with a known history of mefenoxam-insensitivity on their farm should use Presidio, Previcur Flex, or Ranman plus a Phosphite fungicide in rotation in their drip application programs. Importantly, if mefenoxam has not been used in particular fields on any crop for a number of years (more than 5+) the fungus may revert back to being mefenoxam-sensitive and control with these products may return.

For more information please see specific fungicide labels, crops sections, and greenhouse uses in Table E-11 in the 2020/2021 Mid-Atlantic Commercial Vegetable Production Recommendations Guide.
