Safe environment-friendly acaricide

Abstract

The invention provides a safe environment-friendly acaricide. The formula of the acaricide comprises the following components in weight percentage: 1.0-10.0 percent of ethoxylated lauryl alcohol sulfates, 1.0-10.0 percent of coconut acid glycol amide, 1.0-10.0 percent of sodium dodecyl benzene sulfonate, 0.5 percent of NaOH, 1.0 percent of salt, 0.1-0.5 percent of Kathon and 68-95.4 percent of water; the best formula comprises the following components in weight percentage: 5 percent of ethoxylated lauryl alcohol sulfates, 5 percent of coconut acid glycol amide, 4 percent of sodium dodecyl benzene sulfonate, 0.5 percent of NaOH, 1.0 percent of salt, 0.2 percent of Kathon and 84.3 percent of water. The acaricide only takes the action of contace poison on the larvae of insects and mites, hasthe function of controlling fungous and bacterial diseases and has no toxin on other animals of people, fowls, beasts and the like. Grain, fruits and vegetables applying the reagent do not have pesticide residues, and therefore, the acaricide can be applied at any time and the grain, the fruits and the vegetables can be eaten at any time. By using the acaricide to control the harmful mites, the labour strength of fruit farmers can be relieved, the agricultural production cost can be reduced and the pollutions of pesticide to the environment can be reduced to let consumers have ease food. The popularization and the application of the reagent have good social benefits and huge economic benefits.

Description

Technical field: [0001] The invention relates to a formula of a safe and environment-friendly acaricide, which belongs to the technical field of agriculture. Background technique: [0002] Herbivorous mites have the characteristics of small size, rapid reproduction, short development period, small range of action, strong adaptability, high mutation rate and easy occurrence of drug resistance, and are recognized as the most difficult pest group to control (Wang Ning, Xue Zhenxiang, 2005). Taking the citrus red spider Panonychus citri as an example, the citrus red spider is currently the most serious major pest on citrus in my country, mainly damaging citrus leaves, branches and fruits. When the damaged leaves and fruits are severe, they turn grayish white. It loses its luster until it turns yellow and falls off. It occurs in our country for several generations a year, and the generations overlap, causing great harm. In severe cases, the leaves of fruit trees turn green and...

Problems solved by technology

Due to the emergence of drug resistance and the decrease in the number of natural enemy populations, the interval between the application of pesticides to prevent and control citrus red spiders is generally about 15 days, and pesticides need to be applied once every 7 days during the high-incidence period, which increases the labor intensity of fruit farmers and increases production costs. Pesticide residues are increased, and the agricultural ecological environment is damaged. Fruit farmers are often poisoned by pesticides, and consumers are also affected by eating fruits with pesticide residues (Marina, Hu Junhua, Lei Huide, 2008)

[0006] The main problems of the currently used acaricides are in three aspects: 1. Domestic acaricides are cheap, but the effect is poor, and harmful mites are prone to drug resistance; 2. Imported acaricides are effective, but the price It is expensive and difficult for farmers to accept. Therefore, it limits the promotion and use of imported acaricides in China; 3. Whether it is domestic or imported acaricides, there are residual problems, which have caused serious pollution to the environment.
