The present invention is directed to methods of producing liquid sabadilla extract. The invention also relates to methods for controlling pests by application of liquid sabadilla seed extract to pests' environment or to pests.

The present invention refers to an insecticidal composition based on natural extracts for control and/or elimination of pest insects in agricultural crops in greenhouse and/or in the field in general, characterized in that it comprises: a) 20%-80% of natural extract of Allium sativum; b) 20%-80% natural extract of Heliopsis longipes and c) 18% -10% of a surfactant; all of this must sum up to 100%.

The percentages of each component in the composition of the present invention provide a synergistic effect with greater effectiveness and a longer effect in combating pest insects, guaranteeing control of adults, nymphs, pupae, larvae, and eggs; especially of adults altering their eating and sexual behavior, causing paralysis and toxicity; especially in mites of agricultural importance of Acaridae, Eriophydae, Tenuipalpidae, Tetranychidae and Tarsonemidae families.

Garlic extract (Allium sativum), in its composition, has an effect on the nervous system of mites and insects in general, acting in synergy with the extract of Chilcuague (Heliopsis longipes). Chilcuague (Heliopsis longipes) extract has a paralyzing and toxic effect on mites and insects in general, mainly attacking adult populations.

The garlic extract (Allium sativum) is obtained by maceration method with settle, while the extract of chilcuague (Heliopsis longipes) is obtained by the solid-liquid extraction method with constant stirring. Both extracts are obtained using water or organic solvents and subsequently are combined and mixed with a surfactant.

The present invention is directed to mixtures comprising sabadilla alkaloids and at least one essential oil and methods of controlling pests including insects, mites and nematodes by application of mixtures comprising sabadilla alkaloids and at least one essential oil.

The present invention is directed to mixtures comprising sabadilla alkaloids and at least one essential oil and methods of controlling pests including insects, mites and nematodes by application of mixtures comprising sabadilla alkaloids and at least one essential oil.

Insect-repelling compositions comprise from about 0.001% to about 10% by weight of plant essential oils. The balance of the composition to 100% by weight includes deionized water, vanillin powder, isopropanol, glycerin, an emulsifier (such as polyglycerol oleate and/or sodium lauryl sulfate), and an aqueous chitosan formulation. The chitosan formulation comprises ≤8% volume of chitosan and ≤8% volume of acetic acid or vinegar.
