Abstract
Abstract Tremorgenic mycotoxins produced by fungi in the genera Penicillium, Aspergillus, and Claviceps have been found to have potent insecticidal and growth inhibitory activity against the corn earworm and the fall armyworm. Penitrem A and dihydroxyaflavinine are most effective.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
35 words
A method of controlling agronomically important insects comprising applying to a locus of said insects an insecticidally effective amount of a fungal tremorgenic metabolite containing an indole moiety, wherein said metabolite is not cyclopiazonic acid.
Claim 2
Independent Claim
35 words
A method of controlling agronomically important insects comprising applying to a locus of said insects an insecticidally effective amount of a fungal tremorgenic metabolite containing an indole moiety, wherein said metabolite is not cyclopiazonic acid.
Claim 3
Dependent Claim
13 words
