Abstract

The present invention provides natural and/or simulated, synthetic, synergistic pesticidal compositions comprising terpenes, such as extracts from Chenopodium ambrosioides near ambrosioides, or compositions based on those found in Chenopodium ambrosioides near ambrosioides. The present invention also provides methods of using said compositions to kill, inhibit, prevent and/or repel plant pests from contacting and/or damaging plants.

Claims

1. A method of controlling insects and/or mites comprising applying to a plant or plant part and/or applying to an area around a plant or plant part an insecticidally effective amount of a composition comprising (i) a simulated blend of an essential oil extract of Chenopodium ambrosioides near ambrosioides, wherein the simulated blend consists essentially of substantially pure α

-terpinene, p-cymene and limonene, wherein each of the substantially pure α

-terpinene, p-cymene and limonene is not obtained from a Chenopodium extract and (ii) a carrier.

2. The method of claim 1, wherein the α

-terpinene and p-cymene are synthetically produced and the limonene is obtained from a plant other than Chenopodium.

3. The method of claim 1, wherein the carrier is a vegetable oil.

4. The method of claim 1, wherein the composition is diluted before application and wherein the simulated blend in such composition after dilution consists essentially of about 0.010% to about 0.21% by weight of α

-terpinene, about 0.004% to about 0.08% by weight of p-cymene, and about 0.003% to about 0.063% by weight of limonene.

5. The method of claim 1, wherein the composition is diluted before application and wherein the simulated blend in such composition after dilution consists essentially of about 0.02% to about 0.08% by weight of α

-terpinene, from about 0.008% to about 0.032% by weight of p-cymene, and from about 0.006% to about 0.026% by weight of limonene.

6. The method of claim 1, wherein the insect is selected from the group consisting of a thrip, an aphid, a psyllid, a white fly and a lepidopteran.

7. The method of claim 1, wherein the mite is a two-spotted spider mite, a Pacific spider mite, or a European red mite.

9. The composition of claim 6, wherein the carrier and/or volume filler is a vegetable oil.

10. The composition of claim 6, wherein the relative ratio of the α

-terpinene to p-cymene to limonene is about 30 to about 50 α

-terpinene, about 10 to about 20 p-cymene and about 5 to about 20 limonene.

8. A composition comprising an insecticidally effective amount of (i) a simulated blend of an essential oil extract of Chenopodium ambrosioides near ambrosioides, wherein the simulated blend consists essentially of a volume filler and substantially pure α

-terpinene, p-cymene, and limonene, wherein each of the substantially pure α

-terpinene, p-cymene and limonene is not obtained from a Chenopodium extract and (ii) a carrier.
