Take a quick survey to help with Field Equipment Sanitation Research!

In a Specialty Crop Research Initiative (SCRI) grant designed to guide future solution and resources centered around field equipment sanitation, collaborative team comprising pathologists, weed scientists, agronomists, and experts in agricultural equipment sanitation has crafted a questionnaire. This questionnaire is designed to gather growers’ input on their current practices and determine the necessity for implementing new ones.

The research will develop a more comprehensive understanding of the challenges associated with field equipment sanitation and work toward developing solutions that are effective, implementable and sustainable.

To introduce the survey and forthcoming research effort, Dr. Matt Grieshop, lead PI on this project indicates that “We are a group of agricultural research and extension professionals from across the United States that are curious about grower and agricultural professional perceptions about the importance of field equipment sanitation to mitigate the spread of organisms that pose human health, weed, plant pathogen or other risks.

Agricultural field equipment includes tillage implements, tractors, harvesters, cultivation equipment, trucks, trailers, sprayers, mowers, or any other piece of equipment that is shared across fields.

This information will be solely used to help frame future research questions and outreach activities.  It will not be published or distributed in any form. Answering should take 5 minutes or less and is completely voluntary and anonymous.

Your participation is invaluable to future developments in the industry regarding food safety and equipment sanitation. We need more inputs from New Jersey specialty crops growers so that they have a say on the direction that field equipment sanitation research will take in the future!

Get ready for bagworms…NOW

Days old bagworm size

Days-old bagworm = critical management target – T. Waller – RCE

Bagworms should begin hatching NOW through – 4 weeks in NJ, beginning in the southern regions. Now is an optimal time to get this pest on your radar and prepare materials or approaches to attack first/second instar caterpillars. The control window for this pest is typically between 600-900 GDD50  when they begin to hatch and become airborne, i.e. the “ballooning” phase. It is important to check for egg-hatch prior to applications for greatest chemical efficacy, and to continue scouting as they often hatch and develop at asynchronous rates.

It is critical to target these insects EARLY!

Bagworm management – mechanical: If eggs have not hatched: hand-remove sacs/bags. Typically female/egg filled sacs are higher in the canopy so keep that in mind while scouting. This removes the problem from the field or landscape.

Treatment options for Lepidoptera (caterpillars) to have at the ready – containing: B.t. (Bacillus thuringiensis), spinosad , bifenthrin ), cyfluthrin, carbaryl, chlorantraniliprole, cyclaniliprole, cyclaniliprole + flonicamid, Lambda-cyhalothrin, cyantraniliprole, Indoxacarb.  NOTE – Lethal pesticide doses are important, as sub-lethal doses can trigger early pupation, making the pest all but invincible to chemical or biological treatments. Follow label exactly.

IT IS CRITICAL TO ROTATE MATERIALS (Rotate between IRAC groups)

Spotted lanternfly (SLF) hatch is ON in Southern and Central NJ – ALL New Jersey COUNTIES are now QUARANTINED

Spotted Lanternfly nymphs will be emerging now through the first week of May for Southern and Central New Jersey – reduce their population early in the nursery industry!

Two important notes:

  • Through conversations with nursery operators, state inspectors (NJDOA), and internal agent communications SLF hatch has begun, which indicates a critical time to knock down nymph populations with CONTACT insecticides.
  • The entire state of New Jersey is now within the SLF QUARANTINE!

Tree Fruit IPM Report for April 18, 2023

Tree Fruit Phenology: Tree Fruit Phenology remains advanced in peach, but development is slowing. In southern counties all peach orchards are late bloom to petal fall. Redhaven was at approximately full bloom on April 4. Plums are at shuck off. Pears are at petal fall. Red Delicious is just past full bloom. Sweet cherries are at about late bloom depending on variety. [Read more…]
