UNIVERSITY PARK (Centre Co.)-Does it pay to spend the extra money for Bt hybrids? Unfortunately, the most com mon answer is usually "it depends". Listed below is a list of crite ria developed by Dr. Dennis Calving, Penn State, to help determine if Bt com would pro vide an economic advantage to your operation. 1. History of European com borer damage in field, and plan ning on com in the same field next year. 2. Earliest planted fields, either long or short season com. 3. Fields that are low lying, next to streams, or waterways. 4. Fields that are surrounded by dense grassy vegetation. 5. Fields planted at popula tions of more than 26,000. 6.

J HARDWARE - FARM SUPPLIES • CRANE SERVICE these criteria, they would be fields that could receive the biggest economic benefit from using Bt seed. Since not all Bt hybrids are created equal, there are several factors you should keep in mind when deciding on which Bt hybrids to purchase. 1. Check yield data on any Bt com you may have planted this year. Compare this data to our non-Bt varieties. 2. Remember some Bt com varieties only provide protection of first generation infestation. Second generation infestations usually cause the most economic damage. Check to see if the vari ety has protection against sec ond generation borer pressure. 3. A Bt com variety should meet all your other require ments, besides having the Bt gene. 4. Yield checks are the only sure way to determine the value of a Bt hybrid. Some Bt com will look better than some of the non- Bt numbers. 77
