I need up primarily using DE instead of Neem to suppress insect activity on the girls. I used yellow sticky sheets hung above the plants to monitor insect activity changes. When spring temps were in the 80's and low 90's the white files were a major concern with massive plume swarms in the early AM hours. The plants were already well established but were being effected. I started dusting the plants with DE and blasting the nearby trees and foliage with water to knock any eggs or hiding insects during the heat of today. I would spray neem and DE in the evening on the surrounding tree and rose foliage. I bought both praying mantises and lady bugs. I haven't dusted DE in about a month since the beginning of the stretch. The heat also killed most of the white flies and other nuisance insects. There are a number of spider species in the area that are very active making web nets all around insect activity. Just the other day while trimming some under growth, we found a few mantises and lady bugs. They are typically around in the cooler times of the day. The residual DE under the canopy doesn't seem to bother predator insects, although i have been shaking the plants to dust off the rest of the DE every day or so. I decided not to rinse the plants down as this will leave them wide open to attack, as I will not be putting ANYTHING to deter the insects, since they are now in full flower mode. AS the weather cools i will undoubtably may get more insects. The rains, if they come will kill them off and I am ready with hoop house cover.
