Field and Forage Crops |
A lot of peanut fields have caterpillars, but in most cases the heavy rains have beat them into submission. In the majority of fields, the caterpillars are not near threshold and most are fairly mature and will stop feeding soon. A lot of them are also fall armyworms, which are less damaging than corn earworms, and we have relatively rank vines in most situations. In other words, I think it will be extremely rare to see a field in need of treatment. There are a few fields with aphids, but again one must consider that it is getting very close to harvest. These are probably cotton aphids and in some cases may have been set off by the application of a foliar insecticide earlier in the season. Add to that the fact that there are no insecticides labeled for cotton aphids in peanuts and it is something we'll just live with this year. We are seeing a lot of plants begin to turn yellow in quite a few fields and some of this is certainly tomato spotted wilt virus expressing itself late in the season.
