Florida: Insects Stirring In Panhandle Crops

At the beginning to middle of the month I was seeing different species of armyworms. Fall armyworms are usually more active in July but they are turning up sporadically just the same.

Kudzu bugs moved into our soybeans at the Extension Office during the middle of June.

Earlier this week I noticed quite a few redbanded stink bugs in them, as well. This is a leading soybean pest for Louisiana and it is difficult to control. Chances are, it will be a problem for fields in this area if a large enough population develops.

Yesterday while at the North Florida Research and Education Unit in Marianna we collected several rednecked peanut worms after seeing their feeding damage on peanuts about 60 days after planting. They usually are not worth treating, especially if a field is healthy. They just cause cosmetic damage by feeding in the terminals. However, if the field is stressed or young there may be situations where it is worthwhile to spray.

Crown rot is still showing up in younger peanuts. It does not normally affect plants after the 35-40 day range (older plants). I have not seen much in way of leaf spots but expect them to ramp up in the coming weeks when it is no longer raining every day.

The rain has also caused problems with herbicide use and weed control.

As far as cotton goes, I am seeing fields that range from 3 to 4 true leaves up to plants that are waist high. I was out earlier this week looking for foliage feeding pests and did not see many. However, several fields did hold very high populations of aphids.
