Pesticide for preventing and treating litchi stinkbug and preparation method thereof

Abstract

The invention relates to the technical field of pesticides, and discloses a pesticide for preventing and treating litchi stinkbug and a preparation method thereof. The pesticide is prepared from the following raw materials in parts by weight: 8-17 parts of Sphagneticola trilobata volatile oil, 7-16 parts of cypermethrin, 5-12 parts of Melia azedarach extract, 11-20 parts of bergamot oil, 5-13 parts of purslane, 3-12 parts of scallion, 2-10 parts of Azadirachta indica flower, 32-42 parts of vegetable oil, 6-12 parts of cosolvent and 2-12 parts of surfactant. The pesticide can effectively prevent and treat litchi stinkbug and enhance the litchi yield. The residual life of the pesticide liquor is only 7-10 days, so the liquor is safe for people and livestock. The invention also discloses a preparation method of the pesticide for preventing and treating litchi stinkbug. The pesticide for preventing and treating litchi stinkbug has the advantages of high litchi stinkbug prevention effect, short killing time and no pollution, greatly reduces the base number of pest population, and has huge advantages in preventing and treating litchi stinkbug.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a pesticide for controlling litchi bugs 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, sour, warm in nature, e...

AI Technical Summary

Problems solved by technology

Most of the pesticides used to control litchi bugs in China are traditional chemical pesticides. The use of these pesticides is often only considered from the control effect, and it is difficult to take into account other issues including environmental pollution, use safety and drug resistance.

However, the pesticide developed specifically for the treatment of lychee stinkbug has not been reported yet.

[0004] Although some results have been achieved in the current research on the pesticide components of botanical sources to control litchi bugs, most of them are used in combination with chemical agents. Although the control effect may be good, there are toxic and side effects on humans, animals and the environment. For example, Chinese patent 201110001905.7 An insecticidal composition containing sulfoxaflor and butylene-fipronil has such problems, although the patent uses a combination of chemical agents to achieve synergistic effects, which may increase the control effect on lychee bugs, However, there are not enough relevant experiments to prove the safety of its use

However, there is no report on the use of wedelia volatile oil, neem extract and cypermethrin to control litchi stink bugs
