Pesticide for control of lichee lump gall mite and preparation method thereof

Abstract

The invention relates to the technical field of pesticide, discloses pesticide for control of lichee lump gall mite and preparation method thereof. The pesticide is prepared by weight from 13-24 parts of yellow cinnamomum camphora leaf naphtha, 7-17 parts of dicofol, 8-15 parts of chinaberry extract, 13-22 parts of bergamot oil, 6-14 parts of fructus cnidii, 5-15 parts of scallion, 4-13 parts of neem tree flower, 34-48 parts of plant oil, 8-15 parts of assistant solvent agent and 2-10 parts of surface activate agent. The pesticide controls lichee lump gall mite with good effect and raises lichee production quantity. The pesticide lasts 8-10 day of liquid residual period, is safe from human and animal contact. The invention provides also controlling lichee lump gall mite pesticide preparation method. The pesticide preparation is made conformable to rule, applies high control effect to lichee lump gall mite, kills pesticide in short time, keeps environment green and free of insect harm, reduces insect base species amount, functions significantly better for preventing control of lichee lump gall mite.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a pesticide for preventing and treating gall mite in litchi and a preparation method thereof. Background technique [0002] Litchi (scientific name: Litchi chinensis Sonn. ) Sapindaceae, litchi is an evergreen tree, about 10 meters high. The peel has scale-like protrusions, bright red, purple. Bright red when ripe; seeds are entirely covered by a fleshy aril. Flowering in spring, fruiting in summer. The pulp is translucent and creamy when it is fresh, and has a delicious taste, but it is not resistant to storage. Distributed in the southwest, south and southeast of China, Guangdong and southern Fujian are the most cultivated. It is also cultivated in Southeast Asia, and there are records of introductions in Africa, America and Oceania. Together with bananas, pineapples and longan, lychees are known as the "four major fruits in the southern country". Lychee is sweet, sou...

Problems solved by technology

At present, chemical control is still the most important means of control of litchi gall mite, but there are no reports at home and abroad, and it is impossible to provide fruit farmers with scientific guidance on the control of this harmful mite

[0004] Although Tumor gall mite has become a worldwide pest, there are still relatively few reports on the prevention and control of Tumor gall mite, and there are only a few documents, such as the journal "Tropical Forestry" No. 1, 2007. Toxicity determination of insecticides against gall mite

In this paper, the efficacy of 3 common acaricides on Eriodritis litchii was analyzed. Although the data seems to have a high control effect, the experimental period is very short. There is no more experimental data to support problems such as resistance and drug resistance. On the other hand, at present, most of the domestic pesticides used to control gall mites in litchi are traditional chemical pesticides. The use of these pesticides is often only considered from the control effect. Others include It is difficult to balance the issues of environmental pollution, use safety and drug resistance

However, there is no report on the pesticide developed specifically for the treatment of litchi tumor gall mites.

It is impossible to provide fruit farmers with a scientific system to guide the prevention and control of pest mites
