Bacterial Spot of Stone Fruit

Over the past 7-10 days it has become clear that a bacterial spot epidemic is underway. It is eerily reminiscent of the epidemic of 1997, although so far it does not appear as widespread or affecting all cultivars as that year. Many blocks are dropping leaves this week, and fruit lesions are beginning to appear. Remember that it takes about a week for leaf infections to appear, and about 2 weeks for those infected leaves to start dropping. It takes about 3 weeks for those same infections to show up on the fruit. Looking back at weather records over at CoCoRaHs (choose your dates and local observations) it appears that the severe winds of May 23, and the rains over the weeks that followed set up a conducive environment for the bacteria in southern counties.  We are seeing leaf drop in many locations regardless of treatment. The coming week will tell the story of how much fruit infection there is. [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.
