Cynanchum komarovii bactericidal agent miscible oil and microemulsion

Abstract

The invention discloses a cynanchum komarovii germicide emulsifiable solution and a microemulsion. The preparation includes grinding the root, the stem, the leaf and the fruit of the cynanchum komarovii; obtaining the cynanchum komarovii extractive by concentrating the extracting solution into half weight of the cynanchum komarovii grinding material after being extracted in methanol; preparing the cynanchum komarovii germicide emulsifiable solution with the extractive, the solution and inert ingredient; adding water to the emulsifiable solution to obtain the cynanchum komarovii germicide microemulsion, wherein the concentration expressed in percentage by weight of the cynanchum komarovii extractive is 5%-50%. The germicide emulsifiable solution or the microemulsion can effectively prevent and cure various crop diseases including the rice seedling blight, the wheat scab, the tomato and cucumber botrytis cinerea, cotton verticillium wilt, etc.; and has the advantages of low toxicity, low residual, safety for human, animals, fish and birds, so that the germicide emulsifiable solution or the microemulsion is a non-pollution ecological germicide and is applicable to the green agriculture production.

Description

technical field [0001] The invention belongs to the field of pesticide processing, in particular to plant-source ecological pesticide processing technology, in particular to a bovine heart pod fungicide emulsifiable concentrate and microemulsion. Background technique [0002] Cynanchum komarovii AI.Iljinski belongs to the genus Cynanchum komarovii AI.Iljinski, which is a perennial erect and semi-erect herbaceous plant, commonly known as black heart neck, old melon head, and reed heart grass. Perennial herb, 30-50cm high, thick fibrous roots, mostly clustered stems, erect. The seeds are oval, tan, flat, with white cherry blossoms on the top, germinate in April, bloom in June-July, and bear fruit in August-September. Xerophytes, sand-loving, drought-tolerant, xerophytes grow on sand dunes, sandy land, and desertified grasslands in desert and semi-desert areas, and can become constructive species in severely degraded grasslands. It is mainly distributed in the Ordos Plateau i...

Problems solved by technology

With regard to the application of burdock in agriculture, a large number of studies at home and abroad have shown that burdock has good control effects on aphids, mulberry beetles, armyworms and cabbage caterpillars, and the alcohol-extracted crude extract from the grass of burdock has a good effect on tobacco mosaic leaves. Viruses have high inhibitory activity. For example, the Chinese patents "CN1321642 Bougainvillea Extract and Its Application" and "CN1125048 Bougainvillea Compound Plant Pesticide" are all focused on the above aspects, but there are few reports on the use of Bougainvillea in the development of botanical fungicides.
