I don't get why you guys are spraying fields with only a few aphids per plant and killing all the beneficials.
if it were a different forecast of weather or later in the season i would probably hold off on spraying, but with a forecast that will have there population simply explode we have to kill some good to stop a lot of bad.
there is simply no chance of predator bugs keeping up with aphids once they get rolling. remember they are born pregnant and only takes a week to have the next generation. you can go from a dozen to a couple hundred in very little time. |
Any soybean aphids ?
