Pesticide for preventing Arbela dea and preparing method thereof

Abstract

The invention relates to the technical field of agricultural chemicals, and discloses a pesticide for preventing Arbela dea and a preparing method thereof. The pesticide is prepared from, by weight, 13-26 parts of volatile oil of Xanthium italicum Moretti, 10-18 parts of phoxim, 7-16 parts of extractive of Artemisia scoparia, 12-25 parts of bergamot oil, 6-18 parts of Portulaca oleracea L, 5-15 parts of Welsh onion, 6-13 parts of Azadirachta Indica A.Juss tree blossoms, 40-52 parts of vegetable oil, 7-14 parts of cosolvents, and 3-13 parts of surfactant. The pesticide for preventing Arbela dea can effectively prevent the Arbela dea and can improve improve litchi yield. Besides, the residual period of the pesticide is only 7-10 days, therefore the pesticide is safe to people and livestock. The preparing method of pesticide for preventing Arbela dea is also provided by the invention. The pesticide for preventing Arbela dea is characterized by having reasonable concerted application of pesticides, high controlling effects on Arbela dea, 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 Arbela dea.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a pesticide for preventing and controlling the litchi wood beetle moth 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...

AI Technical Summary

Problems solved by technology

At present, domestic pesticides used to control Lychee beetle moths are mostly 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, there is no report on the pesticide developed specifically for the treatment of the litchi wood beetle moth.

[0004] Although some results have been achieved in the current research on the chemical control of botanical control moth, most of them use traditional chemical pesticides. Although the initial control effect may be good, there will be toxic side effects on humans, animals and the environment. At the same time, there are also problems such as drug resistance. For example, the periodical "Fujian Agricultural Science and Technology" 1999 S1 period S1 occurrence and control of litchi wood beetle moth, the abstract introduced several control methods for litchi spinosa moth, wherein the method of chemical control It is to use several traditional insecticides to spray on lychee trees. This method of prevention and control is difficult to deal with problems such as safety, environmental pollution, and drug resistance. In addition, the method of artificial prevention and control has high labor costs and a large workload. , the contribution is not necessarily proportional to the control effect

After reviewing other literatures, we did not find any special pesticides based on natural and non-polluting plant sources for the control of Litchi spinosa moth
