Fall armyworms attack a wide range of grasses and other crops. Outbreaks have been reported on soybeans, sorghum, pastures and several other crops for over a month. We are having a biblical year with fall armyworm, especially in pastures and lawns. However, many are also wandering into the edges of soybean fields. My colleague, Dr. Frank Hale, recently sent the following information. Continue reading

Updated Sugarcane Aphid Distribution
Below is the updated, known distribution of sugarcane aphids in 2014, including confirmed finds on sorghum in Tennessee. This aphid is certainly present in at least low numbers in other areas. The second map shows the distribution of this invasive pest in 2013, showing the impressive spread Continue reading

Insect infestations have been generally mild in soybean fields thus far, but as usual, I am starting to get more calls about stink bugs and a few other pests.

This may include corn earworm infestation in our latest maturing fields. Continue reading
Cotton Insects – Nearing the End
The bollworm flight has begun in many areas. A general decline in plant bug populations is being observed, but stink bugs continue to linger. Some fields of cotton have now reached a maturity where we should and have terminated insecticide applications for plant bugs, stink bugs and bollworms. For later maturing fields, it may still be necessary to manage pest infestations for a Continue reading

Aphids have now also been found in Shelby and Dyer Counties, so it seems likley they could be found in any sorghum field in west Tennessee. I must emphasis that overall populations are very low and don’t appear to Continue reading
