There are hundreds of Bt natural BT proteins and hundreds more we can take a
nasty racial on to make them more effective to meet the needs of killing
worms for a long time. As verities develop rotation of BT strains so less
resistance is likely to happen is a real likelihood.

Given the way resistance usually works I wouldn't count on new strains
of BT overcoming resistance. However BT isn't the only insecticidal bio-
control molecule.
