Early Defoliation Demonstrations and Activity
22
Aug
2012
On August 21 a defoliation demonstration was sprayed at the entrance to the West TN Research and Education Center in Jackson. It is on the east side of the main drive about half way to the main building. Signs will be posted if you have interest in looking at the treatments. Cotton ranging from just reaching cutout to having nearly 100% open bolls is complicating defoliation decisions. Below are several scenairos to consider: Continue reading

Another bug identification quiz for you. These are the eggs of a predator which is sometimes mistaken for a pest. This species lays its eggs in a cluster. A crown of spines around the top of each egg is a good hint. Both the nymphs and adults will attack may different kinds of prey, but they are commonly seen feeding on caterpillars. They are often found in soybean and cotton. The scientific name for this species is Podisus maculiventris (Order Hemiptera; Family Pentatomidae). Still don’t know? Continue reading

As I said last week, we should have heightened awareness for this pest, especially in late maturing fields of soybean and susceptible cotton fields. Beet armyworm moth catches were well up Continue reading
