West Plains IPM update

Cotton continues to make good progress during this moderate weather and following some much-needed rain. Most cotton fields have bloomed out the top/bolled to the top. Most fields have shed all young fruit which will not contribute at harvest and are now filling bolls. Scouting the last few days and gauging the cotton plant I do not think water will need to be turned back on with few exceptions in areas which did not receive enough to finish out. I would be hard pressed to recommend irrigating after September 15 th. I hate to use calendar dates, however, here at the end we only have so many days, day length, sunshine, and heat units left to accumulate. So, all that equates to forcing the plant to mature out sooner than too late. In fact, many acres which received +1.5” could very well take back off growing vegetatively. Every day from here out we should be seeing more cracked and open bolls. We will discuss harvest aid timing here next week.

I am not finding much of any insect pest activity of importance. I can still find a few solitary cotton aphids, not in colonies. I am not seeing stink bugs. If Lygus are present, they are most likely damaging younger fruit which will not contribute to yield and are not worth protecting.

Grain sorghum that is still flowering to soft dough needs to be watched carefully for sorghum aphids, headworms, Lygus, stinkbugs, and midge.

Insect pests are as variable as the sorghum is in growth stage.
