IPM Update 6/03/20

Sweet Corn

Increasing numbers of European corn borer (ECB) moths have been captured over the past week, although overall numbers remain low.  At this time, activity is highest in central Morris County and western Burlington County (see ECB map at left).  The number of traps registering moderate catches is fairly low, and catches are widely dispersed.  Overall, this year’s population is late, and whether numbers increase much or not remains an open question.  Early corn is now in whorl or pre-tassel stage and able to support ECB larvae.  It is time to begin scouting corn in these advanced growth stages.

 

 

 

Look for the characteristic “shot-hole” type of feeding (photo below at right) and consider treating when infested plants exceed 12% in a 50 plant sample.  As plantings proceed to the pre-tassel stage, ECB larvae may be found in emerging tassels (see photo at left).  It is a good idea to treat individual plantings as they move into the full tassel/first silk stage one time.  This eliminates any ECB larvae that have emerged with the tassels as they begin to move down the stalk to re-enter near developing ears.

Useful insecticides for this particular application include synthetic pyrethroids (IRAC Grp 3), spinosyns (including OMRI approved Entrust) IRAC Grp 5), and diamides such as Coragen (IRAC Grp 28) or materials such as Besiege which include the active ingredient in Coragen.  Synthetic pyrethroids alone should NOT be used for corn earworm (CEW) protection on silking corn.  Control with these materials is very inconsistent.

The highest nightly trap catches of ECB for the week ending 6/03/20 are as follows:

Denville   2 Clinton   1 Milford   1
Asbury   1 Downer   1 Oldwick   1
Bellemeade   1 Eldora   1 South Branch   1
Califon   1 Medford   1 Springdale   1

 

Widely scattered, and low catches of corn earworm (CEW) occurred this past week.   While there was an increase in activity over the previous week, this pest does not pose a threat to sweet corn that has not yet reached the silk stage.

The highest nightly trap catches of CEW in black light traps for the week ending 6/03/20 are as follows:

Chester   1 Eldora   1 Milltown   1 Oldwick   1
Crosswicks   1 Elm   1 Morristown   1

Are Disinfectant Wipes Working for You?

Disinfectant wipes can seem like an easy Disinfecting wipesoption to disinfect surfaces during the COVID-19 pandemic. Label instructions for disinfectant wipes include a “allow to remain wet” statement for efficacy. In many cases, the surface needs to stay wet for at least 4 minutes in order to be effective. Check your product label to verify the time for your specific wipes.

How wet your wipe is to start, how large of a surface you use the wipe on, the surface type and environmental conditions will all impact how long the surface stays wet. In a simple test to evaluate the ability to maintain the required wet time, three disinfectant wipe products were tested on fours surfaces. In an indoor setting at 70 degrees and 60% relative humidity without much air movement these wipes were used on a finished wood surface, a solid countertop, a plastic folding table, and a plastic table cloth. In all cases one wipe on a 4 [Read more…]

EPA Releases Temporary Guidance on Respiratory Protection for Agricultural Pesticide Handlers During COVID-19

U.S. EPA Office of Chemical Safety and Pollution Prevention sent this bulletin at 06/01/2020 03:35 PM EDT Additional Information There is no higher priority for EPA than protecting the health and safety of Americans, especially during the COVID-19 public health emergency.

Hand Sanitizers for Use in the Field

Under the “Interim COVID-19 Guidance for Migrant and Seasonal Farmworkers, Their Employers, and Housing Providers”, employers are required to provide hand sanitizers with at least 60-95% alcohol in various locations and employers are to schedule handwashing breaks every hour.  If soap and water are not available, an alcohol-based sanitizer that contains 60-95% alcohol may be used.  Hand sanitizers may be difficult to find, but a grower can make their own.  Visit the onfarmfoodsafety.rutgers.edu website for a factsheet entitled “Home-made Hand Sanitizer”.  This walks you through how to make a cheap effective sanitizer.

The next question is, what is the proper method to apply and use the sanitizer?  Research has shown that a two-step sanitizer method is the best method for alcohol-based sanitizers.

  1. Step 1: Apply three pumps of sanitizer from the dispenser.
  2. Step 2: Rub hands for 20 seconds making sure to cover the palms, backs of hands, and between fingers up to the wrists.
  3. Step 3: Wipe the hands on a disposable paper towel.
  4. Step 4: Apply one pump of the sanitizer from the dispenser.
  5. Step 5: Rub hands until dry.

Hand sanitizers do not take the place of handwashing before starting or returning to work; after using the toilet; before and after eating and smoking; before putting on gloves; after touching animals or animal waste or any other time hands may become contaminated under the Food Safety Modernization Act or for most audits.

FDA Provides Flexibility to Farms Regarding Eligibility for the Qualified Exemption Under the Produce Safety Rule

The U.S. Food and Drug Administration announced that it will provide flexibility regarding eligibility criteria for the qualified exemption under the Produce Safety Rule during the COVID-19 public health emergency.

 

Under the FDA Food Safety Modernization Act (FSMA) Produce Safety Rule, farms are eligible for a qualified exemption and associated modified requirements if they meet certain criteria:

  • The farm’s food sales averaged less than $500,000 (adjusted for inflation) per year during the previous three years; and
  • The average value of the farm’s sales to qualified end-users exceeded the average value of the farm’s sales to all others during the previous three years. A qualified end-user is either (a) the consumer of the food or (b) a restaurant or retail food establishment that is located in the same state or the same Indian reservation as the farm or not more than 275 miles away.

Because of COVID-19, state and local governments across the United States have instituted public health orders that have resulted in many restaurants and retail food establishments either closing or significantly limiting their operations, leaving many farmers without their usual buyers. The guidance intends to allow affected farmers to shift their sales away from qualified end-users while still being considered eligible for the qualified exemption. Specifically, under the temporary policy announced in the guidance, farms that are currently eligible for the qualified exemption and associated modified requirements will still be considered eligible, even if they shift sales away from qualified end-users, so long as they continue to meet the requirement that their average food sales during the previous three years total less than $500,000 (adjusted for inflation).

 

FDA recognizes that providing flexibility to farms to allow them to shift food sales to available buyers during the COVID-19 public health emergency can help reduce food waste and food shortages. This temporary policy is intended to remain in effect only for the duration of the public health emergency, after which the FDA intends to issue additional guidance.

 

Qualified exempt farms must comply with modified requirements under the Produce Safety Rule, which include establishing and keeping certain records and prominently displaying their name and business address on food packaging or at the point of sale. Farms are responsible for ensuring that the food they produce is not adulterated under the Federal Food, Drug, and Cosmetic Act (FD&C Act) and they should use good agricultural practices to ensure the safety of their produce.
