The Food Safety Modernization Act will impact most growers in New Jersey.
Over the past weeks, we have posted the Questions and Answers for each of the conference calls focusing on subparts of the proposed Produce Safety Rule of the Food Safety Modernization Act on the PPA Food Safety section. For your convenience, the Q&A’s have been collected into a single PDF.
As we go forward growers will want to have effective programs for the management of all of The Big Three insects at this time: Blueberry Maggot (BBM), Aphids, and Spotted Wing Drosophila (SWD).

A new pest of New Jersey Blueberries
We have started to catch Spotted Wing Drosophila adults in low numbers. While these numbers are very low, they do indicate a presence in our production areas.

Bloom has started. 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 the Insect Growth Regulators –IGR- (e.g. Confirm and Intrepid) or Bt products (e.g. DiPel).
From now until August, we recommend monitoring insect populations using pheromone traps. [Read more…]
In 2012 we started a study to compare the efficacy of different trap designs (delta versus wing traps) and colors (white versus red) on Sparganothis fruitworm (SPARG) adult captures. We found that red delta traps (Trécé Pherocon VI) are more effective than white delta traps. White delta traps also catch greater number of honey bees, and it is possible that this saturates the sticky traps. We are continuing this work and testing this hypothesis in 2013. Results from these studies will be presented at future grower meetings.
Experiment set-up to test effect of
trap design and color on
Sparganothis fruitworm captures.
Data show red delta traps to be more effective than white delta traps in catching adult Sparanothis fruitworm.
