The 2020 version of PB 1768, Insect Management Recommendations for Field Crops (and pasture), is now available. The guide has gone through substantial revision this year and closely matches the content on the mobile friendly Disease and Insect Field Guides at https://guide.utcrops.com/. Hard copies will be available soon and distributed through county extension offices and at various educational meetings.
This is a repeat of an article from last year (as a reminder). One of the most consistent yield responses I’ve seen in my time at UT is when a foliar insecticide application is made to wheat at this time of year (late January – late February). An insecticide application, specifically a pyrethroid insecticide, has increased yield by an average of 5.7 bushels/acre. Thus, this application has become a fairly routine recommendation. Insecticides can be co-applied with a herbicide or Continue reading

Cotton – Even for our latest cotton, given an average frost date of around October 15, this is the last week you can likely justify insecticide applications to cotton. Based on average historical temperatures, the last effective bloom date was two week ago. A late flurry of bollworm moth activity has forced some sprays this week, and most folks are electing to Continue reading
Despite a relatively lack luster moth flight, corn earworms (a.k.a. bollworm or soybean podworm) are showing up in some late maturing soybean fields, and as usual the action in centered in the river bottom. The treatment threshold for corn earworm is based on sweep net sampling and using the table below. Continue reading
I don’t think I have had a call about soybean all week, but my observations suggest we need to be scouting for stink bugs in our earliest beans, and in some areas, kudzu bugs. Thus far, caterpillar infestations have been very light. As the bollworm flight increases, closely scout for corn earworm in Continue reading
