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.

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.

Disease Management in Cold-Injured Peach Orchards

Several recent overnight cold periods have damaged newly fertilized flowers and/or very young fruit in New Jersey peach orchards. The percent of injured fruit in any particular orchard block varies with cultivar and location. Some blocks have enough un-injured fruit to be salvaged for the growing season. Their economic return will be sufficient to warrant a continuation of standard practices.

In those orchards that lack sufficient fruit, the tendency may be to abandon the spray program. After all, these blocks will produce no revenue, so any activity will result in a net economic loss. However, this thinking is short-sited.  Without any form of control, the pathogens will use this summer as an opportunity to increase their populations and, therefore, the amount of overwintering inoculum for the 2021 season. Next year will be a struggle to control disease, especially if the weather is favorable for disease development.

In cold-injured, non-bearing orchards, the three diseases of concern are scab, bacterial spot, and brown rot. The goal will be to provide enough control for disease suppression while keeping costs to a minimum. Details for their control are presented below.

Peach Scab. Fusicladium carpophilum, the causal agent of peach scab, overwinters in twig lesions on current season fruiting wood. In southern New Jersey, spores are produced on these lesions from bloom through early July (~ mid-July in north Jersey). During rain periods, these spores are disseminated to both fruit and the current season’s vegetative shoots. So, even though fruit may not be present (or in low numbers), control is necessary to prevent build-up of shoot infections, which will provide inoculum for the 2021 season. Note these lesions will not be visible until next spring.

If control of fruit scab during the 2019 season was excellent (≤ 5% fruit infected), then this is an indication that the current number of overwintering lesions on shoots may also be low. In this case, the application of Captan 80WDG (2.5 lb/A) at shuck split (SS), first cover (1C), and second cover (2C) followed by bi-weekly sulfur (8-10 lb actual/A) sprays until early July should be sufficient for scab control this season. The captan applied from SS-2C will also control any latent brown rot infection on young green fruit (susceptible until pit-hardening at ~ 2C), assuming they are present.

If >5% of fruit were infected with scab at harvest in 2019, then the current number of overwintering lesions on shoots may also be high. In this case, applications of Flint Extra 3.8 fl oz/A (formerly Gem) at SS and 1C and Quadris Top 12 fl oz/A at 2C followed by bi-weekly sulfur sprays will provide a very strong program for scab control; this program will also manage latent brown rot infection on any green fruit present.  If Quadris Top cannot be used because the sprayer is also used on apples (phytotoxicity! see label), then substitute Captan for the Quadris Top.

An intermediate scab program can also be considered. In this case, Flint Extra is applied at SS, Captan at 1C and 2C, followed by the sulfur cover sprays every two weeks until early July.  In all of these programs, the Flint Extra acts as an anti-sporulant on the overwintering scab lesions, reducing spore production by 70% for the entire season.

Bacterial Spot. During the growing season from about petal fall onward, the bacterial spot pathogen Xanthomonas arboricola pv. pruni infects fruit, leaves, and current season vegetative shoots (summer cankers) on susceptible cultivars. Thus, the lack of fruit doesn’t prevent the occurrence of an epidemic on the foliage and shoots. If no control is applied, then a larger than usual number of infected leaves, summer cankers, and epiphytic inoculum may be present going into the post-harvest season. This higher level of inoculum may result in a greater number of spring cankers formed for the 2021 season.

Given the above scenario, some form of disease control or suppression is warranted.  Bi-weekly sprays of a copper bactericide at 0.5 oz actual (metallic) copper per acre should be sufficient. The goal is to keep inoculum levels low advancing into the post-harvest season. Oxytetracycline, applied prior to critical warm, rainy periods, could also be used. However, the expense of this antibiotic is probably not warranted given the lack of economic return from a non-bearing block.

Brown Rot. If no fruit are present, then control is not needed. In low-yielding peach blocks not destined for harvest, the main goal for brown rot control is to prevent the formation of overwintering mummies. If the brown rot pathogen Monilinia fructicola is allowed to infect and colonize fruit very quickly, then the abscission layer in the petiole may be killed. This action will thereby prevent fruit from falling naturally; the fruit remains attached, becoming a mummy.

Fruit should be marginally protected so that they mature, ripen, and fall from the tree before a significant amount of brown rot occurs. A single spray of any fungicide rated with good to excellent control (e.g., Captan, Indar, Bumper, Fontelis) applied between 9 and 18 days prior to harvest should be sufficient.

An alternative to fungicide control at preharvest would be to simply remove the mummies during the winter or 2021 pruning operation. Or the fruit could be removed earlier in the 2020 season. Either way, fruit or mummy removal eliminates the need for a preharvest brown rot spray. Early 2020 fruit removal also eliminates the possibility of scab or bacterial spot infection on any fruit that survived the cold period.
