Because it "has smaller size particles and a better sticker regular sevin" it is apparently is less hot on bees than regular sevin. I have bee keepers who swear that it is quite safe when applied correctly. Based on my data it appears that this is a function of climate. Under dry warm climate of eastern Washington this is likely true. However, under the moist climate of coastal washington it appears to be not as safe as we had hoped. . My bioassay system, however, may not be adequate to discern this sort of differences. A lot also depends on what you are try to control, as there may be better and safer insecticides.
