Abstract

The present invention relates to pesticides. More particularly, the present invention relates to botanical pesticides. In particular, the present invention relates to compositions and methods for controlling plant-infesting pests with plant extracts and notably with compositions comprising oil extracts derived from Chenopodium sp. plant material. The invention further relates to compositions comprising such extracts as pesticidal compositions and providing the advantages of minimal development of resistance thereto, minimal toxicity to mammals, minimal residual activity and environmental compatibility. The pesticidal compositions of the present invention comprises α-terpinene, ρ-cymene, limonene, carvacrol, carveol, nerol, thymol, and carvone.

Claims (7)

1 . A method of controlling phytophagous pests selected from the group consisting of acari and insects, which comprises applying to a locus where control is desired an effective amount of a composition comprising an essential oil extract from Chenopodium ambrosioides comprising alpha-terpinene, p-cymene, limonene, carvacrol, carveol, nerol, thymol and carvone.

2 . The method of claim 1 wherein the pests are acari selected from the group consisting of Tetranychus urticae and Panonychus ulmi.

3 . The method of claim 1 wherein the pests are insects selected from the group consisting of Trialeurodes vaporariorum, Frankliniella occidentalis, Myzus persicae, Bermisia argentifolii, Rhizotrogus majalis and Blissus leucopterus.

4 . The method of claim 1 , wherein the essential oil extract is produced by steam distillation.

5 . The method of claim 1 wherein the composition comprises at least 30% alpha-terpinene, at least 8% p-cymene, at least 5% limonene, at least trace carvacrol, at least 0.1% carveol, at least 0.1% nerol, at least 0.04% thymol and at least trace carvone.

6 . The method of claim 1 wherein the composition comprises a formulation comprising 0.125% to 10% by volume of the essential oil extract in combination with an emulsifier, carrier, spreader or sticking agent.

7 . The method of claim 1 wherein the composition comprises an emulsifiable concentrate comprising between 5% to 50% by volume of the essential oil extract in combination with a suitable emulsifier, carrier, spreader or sticking agent.
