However, it is important to monitor the 2nd generation mines in your orchard since populations can greatly increase from one generation to the next. The second flight has started at the UVM Hort. Nymphs of both WALH and RLH nymphs move slowly and straight ahead. Populations should be monitored. Sprays should be targeted at nymphs.
ERM populations are variable in orchards around the state.
Upon further investigation, it appears that the problem arose from incomplete breakdown of the water-soluble bag in which the product is packaged. It was further noted that if the Pyramite bag is completely dissolved first before adding the NuFilm, the incompatibility problem should not occur. If you do have a problem with CM in your orchard, a spray for the second generation should be applied 1260 DD after the original biofix date. In situations where CM pressure is severe, that application should be followed by another spray 10-14 days . The damage looks similar but occurs at different times in the growing season.
