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.
Claims22
A biopesticide composition formulated for biopesticidal application comprising 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.
A biopesticide composition comprising a suitable vehicle and an effective biopesticidal amount of an analog of a purified glucosinolate breakdown product having a hydroxyl group attached.
A method for killing target pests comprising exposing the pests to an effective biopesticidal amount of at least one compound selected from the group consisting of:
- a) 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;
- b) an analog of a purified glucosinolate breakdown product having a hydroxyl group attached;
- and
- c) a derivative of a purified glucosinolate breakdown product having a hydroxyl group and an organic acid attached.
A biopesticide composition comprising a suitable vehicle and an effective biopesticidal amount of a derivative of a purified glucosinolate breakdown product having a hydroxyl group attached, wherein the derivative of the glucosinolate breakdown product is a carboxyester.
