Pesticide for preventing litchi geometrid moths and preparing method thereof

Abstract

The invention relates to the technical field of agricultural chemicals, and discloses a pesticide for preventing litchi geometrid moths and a preparing method thereof. The pesticide is prepared from, by weight, 18-30 parts of volatile oil of A. conyzoides, 8-17 parts of quinalphos, 8-15 parts of extractive from Duranta repens, 12-22 parts of bergamot oil, 7-14 parts of Cnidium monnieri(L.)Cuss, 4-13 parts of Welsh onion, 4-13 parts of Azadirachta Indica A.Juss tree blossoms, 28-40 parts of vegetable oil, 6-12 parts of cosolvent, and 4-14 parts of surfactant. The pesticide for preventing litchi geometrid moth can effectively prevent litchi geometrid moths and improve litchi yield. Besides, the residual period of the pesticide is only 8-11 days, therefore the pesticide is safe to people and livestock. The preparing method of pesticide for preventing litchi geometrid moths is also provided by the invention. The pesticide for preventing litchi geometrid moths is characterized by having reasonable concerted application of pesticides, high controlling effects on litchi geometrid moths, short killing time, meanwhile the pesticide is free from pollution, sharply reduces the cardinal number of the population of the pests, and has huge advantages in preventing the litchi geometrid moths.

Description

technical field

[0001] The invention relates to the technical field of pesticides, in particular to a pesticide for preventing and treating the litchi inchworm 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...
