IPM Update 6/10/20

Sweet Corn

European corn borer (ECB) moth catches have declined over the past week despite increasing temperatures.  At this time, activity is highest near the Hunterdon/Warren County border, although this is still a low level population (see ECB map at left).  The number of traps registering moderate catches remains low, and catches are widely dispersed.  Another week of trapping will clarify whether this decrease in activity signifies the end of the first flight.  A number of corn plantings are now in whorl through tassel stages and able to support ECB larvae.  Larval infestations as high as 12% were detected as far north as Hunterdon County this week.  As moth catches fall, larval development and damage increase.  We expect that with a few more warm days, these infestation rates will climb quickly in many parts of the state.

 

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 6/10/20 are as follows:

Allamuchy   1 Crosswicks   1 Milford   1
Blairstown   1 Denville   1 Milltown   1
Califon   1 Downer   1 Springdale   1
Chester   1 Eldora   1 Tabernacle   1

 

Widely scattered, but slightly increased catches of corn earworm (CEW) occurred this past week.   As the earliest plantings (mainly in the south) proceed to full tassel and on to silk, even this low population can present a limited threat.

The highest nightly trap catches of CEW in black light traps for the week ending 6/10/20 are as follows:

Califon   1 Downer   1 Green Creek   1
Dayton   1 Georgetown   1 Tabernacle   1

Important Update on Registration of Low-Volatility Dicamba Herbicides

On June 3, 2020, the U.S. Court of Appeals for the Ninth Circuit issued a ruling that vacates current U.S. registrations of of three dicamba herbicides, XtendiMax (Bayer), Engenia (BASF) and FeXapan (Corteva). The Court ruled in favor of a petition challenging the EPA’s 2018 registration decision. The ruling comes after a group of environmental organizations filed a petition with the Court challenging the U.S. Environmental Protection Agency’s . Other dicamba-containing products are not concerned by this ruling.

The subsequent action by the EPA provides, among other things, that “growers and commercial applicators may use existing stocks that were in their possession on June 3, 2020, the effective date of the Court decision. Such use must be consistent with the product’s previously-approved label, and may not continue after July 31, 2020.”

Click here for the EPA’s full order – see page 11 for key details.

The EPA’s order addresses the use, sale, and distribution of existing stocks of  low-volatility dicamba products impacted by the Court’s ruling.

On-Farm Readiness Reviews to Resume

The Food and Drug Administration (FDA) has lifted the restrictions on carrying out On-Farm Readiness Reviews (OFRR).  The New Jersey Department of Agriculture (NJDA) in cooperation with Rutgers Cooperative Extension will start offering OFRR’s in the next couple of weeks.

The objectives of the On-Farm Readiness Review program are to:

  • Offer a voluntary, non-regulatory, pre-inspectional “readiness” review primarily for covered farms and discuss whether the farm is covered by Food Safety Modernization Act (FSMA) Produce Safety Rule or whether the farm may be exempt from parts of FSMA
  • Promote coordination between farmers, regulators & educators
  • Educate regulators about on-farm practices and conditions
  • Familiarize non-qualified farms with the regulations

 

This is a confidential review of individual farm operations.  Usually there are two individuals on the team, one each from NJDA and Extension.  This is not a records review, but an overall assessment of the farm operation and how the farming practices conform to the Produce Safety Rule.  The team walks around the operation with the grower and discusses the different aspects of the farm.  Once the review is over the group sits together and reviews the findings and makes suggestions for possible changes to meet the rule.  Any notes that are taken during the review are left with the grower.

Any fruit or vegetable operation with sales over $25,000 are eligible for the review.  It is encouraged that someone on the farm has gone through the Produce Safety Alliance (PSA) training prior to the review.  The PSA training meets the requirement for training under the Product Safety Rule that someone on the operation must receive training recognized by FDA.

The OFRR is a good way to help a grower understand what is required under the Rule.  How do you schedule for a review?  Contact Chris Kleinguenther, NJDA, at  Christian.Kleinguenther@ag.nj.gov.  Chris will contact the grower and schedule a date and time for the review.

Food Safety Modernization Act (FSMA) Produce Safety Rule Inspections to Resume

The Food and Drug Administration has announced that FSMA inspections can resume when the state is ready.  The New Jersey Department of Agriculture (NJDA) will be starting inspections of fruit and vegetable operations in the next couple of weeks.  NJDA will contact individual growers to schedule the inspection.  These will be educational inspections covering operations with sales of $250,000 and above.  If the farm thinks they are qualified exempt they will need to show some type of financial records for the last three years proving they meet the qualified exemption standard.

To be eligible for a qualified exemption, the farm must meet two requirements:

  1. The farm must have food sales averaging less than $500,000 per year adjusted for inflation during the previous three years.
  2. The farm’s direct sales to qualified end-users must exceed sales to all other buyers combined 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 not more than 275 miles away.

If the operation is qualified exempt the requirement other than the financial records is to label either individual containers or have a roadside stand/farmers market sign prominently and conspicuously displayed that has the name and complete business address of the farm where the produce was grown.

For additional information contact Chris Kleinguenther, at Christian.Kleinguenther@ag.nj.gov

USDA – Farm Service Agency – Coronavirus Food Assistance Program (CFAP)

USDA is providing critical support to our nation’s farmers and ranchers through the Coronavirus Food Assistance Program (CFAP). CFAP provides vital financial assistance to producers of agricultural commodities with financial assistance that gives them the ability to absorb sales declines and increased marketing costs associated with the COVID-19 pandemic.

The attached fact sheet provides an overview of the program.

For more information about the CFAP program, visit farmers.gov/cfap or contact your local FSA office. To find your local FSA office, visit offices.usda.gov.
