ve had a couple of calls related to the use of in-
preferably three weeks prior to planting. This will go a long way in eliminating the chances of cutworm problems, but it is sometimes easier said than done. A relatively low rate of a
pyrethroid insecticide is com- monly suggested to prevent cut- worm damage. However, I do not recommend including an insecticide with herbicide ap- plications that are made more than two weeks in advance of planting. Tank mixing an in- secticide with an early burndown ap- plication does not make much sense. Cutworms you kill would have proba- bly ‘cycled out’ be- fore you planted anyhow. And be- cause you cannot expect much residual control, there is the pos- sibility of reinfestation between application and planting. The best time to make this application is just before or at plant- ing (or within a day or two after planting). A few other points for
your consideration: • No insecticide seed treatments should be ex-
pected to provide substantial control of cutworms. • Although Bt corn and cotton
traits provide some protection against cutworms, planting into fields that are heavily infested is a risky business. Herculex, VT3 Pro, VT2 Pro and SmartStax corn can re- duce cutworm injury, and I would ex- pect the same from the Viptera technology.
In cotton, WideStrike
will suppress cutworm injury better than Bollgard II. However, large lar- vae are much less susceptible to Bt

toxins. So, if populations are high enough, I suspect any Bt technology can be overwhelmed. • Ammo 2.5 EC and its generic
