Engine oil emulsion in water for preventing and controlling icerya purchasi

Abstract

The invention relates to the field of forest pest control agents, in particular to engine oil emulsion in water for preventing and controlling icerya purchasi. The engine oil emulsion in water is milkwhite sticky liquid formed by uniformly mixing waste engine oil and washing powder according to a weight ratio of 1 : 1, and fully emulsifying the mixture. The engine oil emulsion in water organically combines the effectiveness of a pesticide and low toxicity required by environment protection, is an effective substitute product of many organic synthetic pesticides, can be used for preventing andcontrolling the icerya purchasi, mites, aphids, whiteflies, phylloxerae, lepidoptera pests and the like, is unique in insecticidal mechanism, has a good insecticidal effect, and has a sterilization protection function, so that pests difficultly generate resistance; in addition, the engine oil emulsion in water has the advantages of low cost and easy availability as the waste engine oil and the washing powder are adopted as raw materials, no emission and no pollution in preparation and use processes, environment-friendliness, safety to human, animals and plants, usability in four seasons, no toxicity, easiness in residual degrading, and capability of being decomposed and utilized by micro organisms in soil.

Description

technical field [0001] The invention relates to the field of pesticides for preventing and controlling forest pests, in particular to an oil-water emulsion for preventing and controlling scale insects. Background technique [0002] Scale insects, also known as "scale insects", are important pests on citrus and pomelo. Branches and fruit. Male scale insects often have wings and can fly. Once females and larvae emerge, they live on branches, leaves or fruits for a lifetime, causing yellowing of leaves, wilting of branches, decline of tree vigor, and easy induction of soot. Scale insects are difficult to prevent and treat, especially after the insect body is waxy, there is almost no cure. [0003] In the prevention and control of forestry pests, the problem of relying solely on chemical pesticides has always existed, leading to the emergence of resistance, the succession of resistant or more resistant species, and production falling into the "pesticide-resistant pests rampant...
