Problems solved by technology

Some antibiotic drugs are poorly soluble drugs, which are difficult to absorb when entering the pest body, and the killing duration is short, which requires the application of modern pharmacy principles to design new dosage forms
At present, the existing insecticides not only have weak insecticidal effect, but also have poor efficacy and durability, and also have serious damage to the ecosystem.

Abstract

The invention provides a nano-emulsion insecticide including: 1-2 parts of cyhalothrin, 0.1-0.6 parts of spinosad, 0.2-0.9 parts of sophocarpidine, 11-21 parts of a nano titanium dioxide, 200-310 parts of soya bean oil, 52-71 parts of yolk lecithin, 11-17 parts of n-butyl alcohol, 0.2-0.6 parts of Tween, 10-11 parts of abamectin and 5-15 parts of griseofulvin. Compared with the prior art, the nano-emulsion insecticide is low in cost and simple in processes, has excellent insecticidal effect even under very low dosage, has long lasting time and has low damage on ecological system.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a nanoemulsion pesticide and a preparation method thereof. Background technique [0002] Insecticides (English: Pesticide.Insecticide) are mainly used to control agricultural pests and urban sanitation pests. They have a long history of use, large amounts, and many varieties. In the 20th century, with the rapid development of agriculture, pesticides greatly increased agricultural output. However, almost all pesticides seriously alter the ecosystem, most are harmful to humans, and others are concentrated in the food chain. We must strike a balance between agricultural development and the environment and health. [0003] Agricultural antibiotics were developed on the basis of the development of medical antibiotics in the 1940s. Since the 1970s, some agricultural antibiotics with the functions of preventing insects, mites, animal parasitic protozoa and worms, weeding and regulating the g...
