E = excellent, G = good, F = fair, P = poor or no activity, ? = insufficient data to provide confident ranking, NL = pest not listed on label.

** Efficacy of seed treatments on sugarcane beetle is dependent upon the timing of infestation. Expect less control if infestations occur several weeks after emergence.

See the insecticide label for specific use instructions.
* Caution: When using organophosphate insecticides such as Aztec or Counter with herbicides such as Accent, Callisto, Capreno, Halex GT, Steadfast, Option or Resolve, the possibility for plant injury exists. See herbicide label for restrictions.
** Many other pyrethroid insecticides are labeled for at-planting control of cutworms and some other pests. These include Asana XL, Baythroid XL, Declare, Mustang Max and Pounce. Please see their labels for specific use instructions.
- No-till or reduced-tillage farming generally increases the likelihood of soil insect pests.
- Consider using the higher-labeled rates of an insecticide seed treatment or an in-furrow applied insecticide (see tables above) when you have a known soil insect problem, planting in a field that was fallow, pasture or sod the previous season, or a cover crop was used and not terminated at least 3-4 weeks before planting.
- Economic damage from southern corn rootworm, seedcorn maggot, and white grubs is uncommon because most seed corn companies apply an insecticide seed treatment.
- Higher insecticide seed treatment rates or the use of in-furrow insecticides may be needed if wireworms, western corn rootworms, or sugarcane beetles are present in significant numbers.
