This virus is transmitted to peanuts by thrips. C99R has the highest level of resistance currently on the market. Sequential planting dates for green peanut production increase virus problems on later plantings. Lorsban also reduces pod damage from wireworm and southern corn rootworm feeding. However, southern corn rootworm is seldom a problem in S. C. Unfortunately, Lorsban also causes outbreaks of corn earworm, granulate cutworm and spider mites later in the season.
Irrigation is the best defense against lesser cornstalk borer.
Foliage caterpillars - Use a 3' shake cloth to look for corn earworm s starting the last week of July and first week of August, especially on fields treated with Lorsban. Granulate cutworm is also a problem late in August where Lorsban is used. Rank growing peanuts can tolerate 8 foliage feeding worms per row ft. Keep corn earworm off of stressed peanuts especially. Irrigation reduces damage from foliage worms.
