Growers guide to understanding the protectant fungicides (FRAC codes M1 – M9)

-Andy Wyenandt

Protectant fungicides offer broad spectrum control and are used often throughout the growing season. Why don't fungi develop resistance to protectant fungicides?

Cold Injury

COLD INJURY Injury was found this past week in some early season plantings due the most recent cold snap we had early this week. Injury was reported on lettuce and on potato (seen pictured). In some cases, such as pepper and tomato, cold temperatures can damage meristem tissue and injury won't be seen until those leaves flush out weeks later. Often in this type of damage resembles virus infection (especially in pepper) resulting in crimpled leaves and mosaic-like symptoms on leaves.

European corn borer

The first European corn borer moth was found in one of the Vegetable IPM blacklights Monday, in Salem County.  Given the amount of heat accumulation, degree days, this is not surprising.  This first capture is about 2 weeks earlier than last year at this location.  However, this first flight of adults is not yet widespread.  Look for the ECB moth trap catch map in the upcoming issues of the Plant and Pest Advisory, Vegetable edition.
