What percentage of my crop should I plant in B.t.?

This depends on a number of factors centered around a producer's assessment of the threat of potential insect pest damage, especially by tobacco budworm, and the agronomic performance of selected B.t. varieties. The average has been between one-third and one-half of cotton acres on Mississippi farms to be B.t. acres. Unfortunately, tobacco budworm populations can not be predicted in advance, and many growers in Mississippi remember the devastation caused by this pest in 1995. Also, remember that other products for controlling tobacco budworm are available, such as Tracer.
