Cotton – Thinking Ahead About Bollworms
11
Jul
2018
It is uncertain how big our moth flight will be this year. As usual, bollworm moth catches have been generally low to this point. However, you can expect activity to slowly increase, with a peak in moth activity occurring the last week of July and the first week of August. With the decreasing efficacy of pyrethroid insecticides and increasing tolerance to some Bt toxins, you should plan on using Continue reading

Heat unit accumulation during 2017
22
Aug
2017
Heat unit accumulation has been the big question over the past week. Mild temperatures settled over Tennessee during early August and there is some concern that the crop may not be maturing as quickly as noted in years past. While I agree the weather has been quite comfortable, we are currently very close to the 30 year average heat unit accumulation trend noted from 1980-2010.

Don’t freak out about Japanese beetles
06
Jun
2017
They’re back, but they don’t scare me! It is very unusual to see economic damage from Japanese beetles in cotton, soybean, or corn. They may cause defoliation in all crops. I’ve never seen enough defoliation in cotton or corn to justify treatment. On a few occasions, I’ve seen enough defoliation in soybean to catch my attention. They will hang around for a while, so in combination with other defoliators, they may cause enough damage Continue reading

Southwestern Corn Borer in Non-Bt Corn
25
May
2017
Moth traps catches clearly indicate that the first generation flight is peaking (link to moth trap catches). Local moth catches may vary considerably, and that is why we suggest running pheromone traps on your farm if you are growing non-Bt corn. The highest trap catches are on farms in U.S. Fish and Wildlife Refuges, primarily because they are not allowed to grow Bt corn. Please link to the publication below for more information about the management of this pest. Below, I’ve also provided the suggested treatment threshold for southwestern corn borers in non-Bt corn during the whorl stage. Continue reading
