Taking an environmentally sensitive approach to pest management
| Table 1. 2011 Commercial Seed Treatments for Corn | |||
| Comments: The insecticides thiamethoxam (Cruiser) and clothianidin (Poncho) are labeled for use as commercially applied corn seed treatments. These seed treatments provide early season protection against injury by several pest insects depending on the rate of insecticide applied to the corn seed. | |||

| Table 2: 2011 Transgenic Corn Hybrids and Bt Traits | |||
| Comments: Management of several insect pests of corn may be accomplished by using corn hybrids which have been genetically engineered to produce Bacillus thuringiensis (Bt) and certain insect toxins. Bt hybrids events and their toxins target specific insect pests. Be sure to match these hybrids to the pests requiring control. Follow all refuse requirements associated with these Bt hybrids. | |||
