Insect Pest Management During Bloom

Cranberries are starting to bloom. If insects have been effectively managed prior to bloom, we recommend no sprays at this time. A reminder: when bees are present your only choices of insecticides are insect growth regulators (IGRs) such as Intrepid 2F or Bt products such as DiPel.

During bloom we recommend monitoring insect populations using pheromone traps. Pheromone traps should be used particularly to monitor activity of Sparganothis fruitworm and blackheaded fireworm, two key pests in New Jersey.

Degree-day model for Sparganothis fruitworm

Figure 1 shows life history benchmarks of interest for Sparganothis fruitworm and associated degree-day (DD) estimates from March 1(Shawn Steffan, USDA-ARS/University of Wisconsin-Madison). Flight initiation is predicted around 595 DD, at a lower temperature threshold of 50°F. Based on this model, Sparganothis has accumulated (starting April 15) 521 DD, meaning that flight should start in about 3 days in our region.

Fruit IPM for 6/9/20

Peach:

Oriental Fruit Moth: We are between generations 1 and 2, with the first insecticide applications due in southern counties in 10 days to 2 weeks. Where trap captures are below 8 moths per trap and no injury is present, then stretch insecticides to get as close to the model timing as possible. Where trap counts continue above 8 males per trap, then the population is too high to take this approach. This is the case in several orchards in northern counties. [Read more…]

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.

Fruit IPM for 6/3/2020

Peach:

Plum Curculio (PC): PC oviposition is coming to an end in most counties. The Cornell model recommends that insecticides are only needed until 308 DD base 50 after apple petal fall. This was June 1 in southern counties and should be about June 5 in Hunterdon County and slightly later north of Pittstown. Therefore applications made this week in southern counties should control this generation of PC. In the southern part of the state we also have the southern strain PC, which has 2 generations per year. Therefore this may be a returning issue in mid-summer.

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…]
