Cranberry Insect Upate

The season has started very slow due to the cold weather.  Insect activity is just starting to increase.  Thus, growers need to intensify their scouting efforts.  The following insect pests bear special mention for early-season scouting:

Blackheaded fireworm – Blackheaded fireworm eggs overwinter on the bed and usually hatch by around mid-May. It is important to catch the first generation, if possible, because the second generation occurs during bloom and is typically much more destructive. Blackheaded fireworm larvae can be detected by sweep net sampling and it is good idea to look along the edges of bed where vines first begin to grow.

Remember: blackheaded fireworm is much easier to control if detected during the early part of the season. [Read more…]

Pesticide Worker Protection Inspection Warning

The New Jersey Department of Environmental Protection Pesticide Control Program (NJDEP) has announced that federal agricultural Worker Protection Standard (WPS) compliance farm inspections will be conducted mid-May through July. Be a prepared agricultural employer. Take the necessary actions this week to make sure your farm is in compliance to avoid citations.

Two outstanding farm employer resources on agricultural WPS compliance are:
1. EPA Ag Employer Quick Reference Guide (2005)
2. EPA website How to Comply with the Worker Protection Standard for Agricultural Pesticides: What Employers Need to Know

These are inspections by the US EPA, although NJDEP inspectors may accompany them. Approximately 20 to 30 inspections are slated to be conducted any time from May through July.

Cranberry Weevil Research

In field evaluations, we demonstrated that yellow sticky traps baited with the blend of four aggregation pheromone components trapped significantly more cranberry weevil adults than un-baited controls.
Development of pheromone-based monitoring lures is an important step toward spatially-precise management techniques that may lead to significant reduction in the use of pesticides targeted against cranberry weevil in blueberries.
