Composite factor-Pesticide process to control a plague to decrease pest resistance to a pesticide to potentiate pesticide pesticide pesticide activity and to obtain a mutant or variant of a strain of baciullus and mutant or variant of a strain of bacillus

摘要

The present invention relates to a factor that potentiates the pesticidal activity of a Bacillus related pesticide as well as methods for isolating and identifying said factor. The invention further relates to pesticidal compositions comprising the factor as well as methods of using the pesticidal compositions to control a pest and decrease the resistance of a pest to a pesticide and potentiate a Bacillus related pesticide. The factor of the present invention may be obtainable from a Bacillus fermentation. In a most specific embodiment said factor has the structure (Ia).
