Problems solved by technology

Organophosphorus, pyrethroids, benzoylureas and biochemical pesticides have been compounded and combined to reduce the original toxicity to a certain extent, but due to the results of years of use, the insects have become resistant to pesticides and resistant to pesticides. The properties of the medicine are strengthened year by year, and the effect of alternate use is not very satisfactory

Embodiment 1

[0019] The insecticide of the present invention is prepared using the following raw materials in weight proportions: 0.01 part of didecyldimethylammonium chloride, 45 parts of deerbite, 0.01 part of tetradecyldimethylbenzylammonium chloride, dichlorobischloride 1.0 parts of arc ethane, 0.01 parts of octoxynol, 20 parts of benzalkonium bromide solution, 15 parts of comfrey, 2 parts of Perrin and 5 parts of demineralized water. Among them, the raw materials of deerbita, comfrey and Peilan are all made of dry raw materials.

[0020] The specific preparation method is as follows:

[0021] (1) Didecyl dimethyl ammonium chloride and tetradecyl dimethyl benzyl ammonium chloride are dissolved in demineralized water successively under continuous stirring to form a mixture;

[0022] (2) Add octoxynol to the mixture in step (1), and stir until uniform;

[0023] (3) Decoct comfrey twice at a temperature of 100°C. The quality of water used for each decoction is 5 times the mass of comfre...

Embodiment 2

[0032] The insecticide of the present invention is prepared by using the following raw materials in weight ratio: 6 parts of didecyl dimethyl ammonium chloride, 55 parts of deer's grass, 6 parts of tetradecyl dimethyl benzyl ammonium chloride, dichlorobis 3.0 parts of arc ethane, 15 parts of octoxynol, 40 parts of benzalkonium bromide solution, 28 parts of comfrey, 7 parts of perrin and 30 parts of demineralized water.

[0033] The preparation method is the same as in Example 1.

[0034] The prepared insecticide was diluted at 1:800, and all the other contrasting pesticides were used according to the instructions. For the peach aphid control test, as shown in Table 2:

[0035] Table 2 The results of the control experiment of green peach aphid

[0036]

[0037] It can be seen from Table 2 that the present invention has a more significant deworming effect than the existing pesticides. After six hours, the deworming rate of the present invention is as high as 98%, which is fa...

Abstract

The invention discloses fruit insecticide and a preparation method and application thereof. The insecticide comprises, by weight, 0.01-6 parts of didecyl dimethyl ammonium chloride, 45-55 parts of pyrola, 0.01-6 parts of tetradecyl dimethyl benzyl ammonium chloride, 1.0-3.0 parts of chlorhexidine, 0.01-15 parts of octoxinol, 20-40 parts of benzalkonii bromidum solution, 15-28 parts of radix lithospermi, 2-7 parts of herba eupatorii and 5-30 parts of softened water. The insecticide is free of pollution, safe and good in insecticide effect.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a fruit insecticide. Background technique [0002] Today, when advocating green and protecting the environment, many highly toxic and high residue chemicals have been limited or discontinued. Organophosphorus, pyrethroids, benzoylureas, and biochemical pesticides have been compounded and combined to reduce the original toxicity to a certain extent. The property of medicine is strengthened year by year, and the effect of alternate use is not very satisfactory. The actual dilution of agricultural insecticides has far exceeded its limited range, and the chemical residues in agricultural products are far from meeting the requirements of pollution-free. The increasing demand for pesticides has caused the aggravation of rural environmental pollution, and its residues are harmful to the human body. It cannot be ignored. Contents of the invention [0003] The object of the pre...
