Abstract: A method for suppressing target pests, comprising exposing the pests to an effective biopesticidal amount of a composition, the composition comprising a carrier and a purified glucosinolate breakdown product having a hydroxyl group attached, wherein a starting material for the purified glucosinolate breakdown product is isolated from a crambe plant or mustard plant, further wherein the target pests are plants, fungi, bacteria or root knot nematodes is disclosed. Methods for suppressing target pests without limitation as to the starting materials are also disclosed wherein the pests are exposed to an effective biopesticidal amount of a composition comprising a carrier and either an analog or a derivative of a purified glucosinolate breakdown product having a hydroxyl group attached.

Abstract: The present invention provides novel biopesticides which can replace commercial pesticides and biopesticides which have been banned, restricted, or are being phased out, including, but not limited to chloropicrin, dichlorvos and methyl bromide. Many of the biopesticides of the present invention are excellent fumigants, possessing quick action and volatility, while posing less risk than currently used pesticides to humans and the environment. The biopesticides of the present invention are natural and closely-related synthetic derivatives or analogs related to two classes of natural compounds, namely glucosinolates and monoterpenoids.
