Problems solved by technology

However, pyrethroids are not as safe as pyrethrum and have the disadvantage of persisting in the environment for a longer period of time
Moreover, the disadvantage is that many insects develop resistance to pyrethroids
[0009] Many natural products including plant essential oils used as pesticides do not provide adequate pest control, they are unstable, break down quickly and therefore do not provide residual toxic properties
Products such as pyrethrums, although they have good contact toxicity to pests when used correctly in insecticide formulations, are not effective insecticides in many cases because they lack residual properties and, therefore, increase Increased frequency of use and cost of pesticide use, as well as increased exposure hazards to the environment

Effect test

Embodiment 1

4 (10mg / cylinder) + pyrethrum

100

[0052] The doses tested for thyme oil, thymol and Blend 5 did not cause any death or signs of toxicity (body weight and appetite) in female rats (8-10 week rats) up to 5 days after treatment. Blend 5 is a mixture of botanical essential oils containing thymol, eugenol, trans-lemeol, alpha-terpineol, and citronellal.

[0053] Examples 1 and 2. These examples show that synergistic compositions containing plant essential oils and / or their principal components and pyrethrums (25% pure pyrethrins) have synergistic activity at smaller concentrations, ie sublethal doses of each.

Embodiment 3

[0054] Example 3 The synergistic and residual effect of the mixture of plant essential oils and pyrethrum and pyrethrum derivatives against American cockroaches

[0055]

[0056] The above data demonstrate that one or more plant essential oils, together with pyrethrum, have synergistic and residual effects. The increased toxicity and increased residual effects of synergistic admixtures are unexpected and offer clear advantages over existing pesticidal technologies.

Embodiment 4

[0057] Synergy and residual effect of embodiment 4 thymol and pyrethrum

[0058]

[0059] These data demonstrate a clear synergistic effect and increased residual toxicity of thymol and sublethal amounts of pyrethrum. This synergy and increased carry over is unexpected and meaningful at such low dosage levels.

Abstract

Synergistic and residual pesticidal compositions containing synergistic and residual mixtures of plant essential oils and / or their constituents, plant essential oils and / or their constituents in admixture with known active pesticidal compounds or plant essential oils and / or their constituents in admixture with other compounds not previously used as active ingredients in pesticidal formulations, such as, for example, so called signal transduction modulators. In addition, the present invention is directed to a method for controlling pests by applying a pesticidally effective amount of the above synergistic and residual pesticidal compositions to a locus where pest control is desired.

Description

[0001] This application is related to U.S. Provisional Patent Application Serial No. 60 / 094,463, filed July 28, 1998, U.S. Provisional Patent Application Serial No. 60 / 100,613, filed September 16, 1998, and U.S. Provisional Patent Application Serial No. No. 60 / 122,803, filed March 3, 1999, the entire disclosures of these patent applications are hereby incorporated by reference. field of invention [0002] The present invention relates generally to insecticide compositions, and in particular to synergistic and residual insecticide compositions comprising essential plant oils and / or essential plant oil components.
