As with most growing seasons, mite pressure so far this year is location dependent. However, as grapes head into the heart of the summer—and its consistent heat—expect that pest pressure to intensify.
“From here-on out as we get into hotter weather is when we’ll see problems with mites,” predicts Chuck Ware, PCA with Wilbur Ellis in Madera, Calif. He notes that he’s been working preventative mite sprays into programs for his growers.
To stay on top of mite pressure, Ware suggests monitoring known problems areas—like weak spots or areas that are dusty. And watch the weather, since higher temperatures are beneficial to mite development.
You can also use this mite monitoring form from the University of California to help stay on top of mite pressure.
Also, evaluate your spray program to make sure you’re ready and able to keep mite populations in check. For instance, Acramite® 50WS miticide delivers good knockdown mite control without affecting beneficials or predatory mites. Acramite eliminates the majority of undesirable mites, giving beneficial insects a head start in keeping mite populations in check. Plus, its unique carbazate chemistry also makes Acramite an excellent rotational miticide for resistance management programs.
Always read and follow label directions.
