The July rain in South Georgia will reduce the severity of lesser cornstalk borer infestations in many fields and will at least buy us some time before spider mites become a serious concern. If the rain continues through the remainder of the season, we will likely not have to battle…

We knew they were coming, and now they are here. The calls, emails, and texts have started to roll in reporting peanut fields in Georgia infested with twospotted spider mite.
