preparation example Construction

[0012] The preparation method of this inorganic pesticide comprises the following steps:

[0013] a) adding each component in the reaction kettle according to the proportion;

[0014] b) stirring, the time is 20-120 minutes, and the temperature is 30-160 degrees Celsius;

[0015] c) Liquid medicine filtration, clarification, packaging.

[0016] If part or all of the sodium chloride and sodium sulfate in the inorganic pesticide components are replaced by potassium chloride and potassium sulfate respectively, the weight ratio of each component remains unchanged, and the same effect can be obtained through testing.

[0017] The insecticidal principle of this inorganic pesticide is that after the strong penetrating medicinal liquid stimulates the body wall of the pest, the pest dies because it cannot carry out normal metabolism. The common feature of pests such as pear psyllids, scale insects, peach aphids, and apple cotton aphids is that there is a layer of wax secreted on the ...

Embodiment 1

[0021] Take 21kg of industrial soda ash, 4kg of ammonium chloride, 4kg of sodium chloride, 3kg of sodium sulfate, and 66kg of water, add each component into the reaction kettle, stir for 40 minutes, and the temperature is 60 degrees Celsius, then filter until the liquid is transparent After clarification, it should be packed in glass or plastic bottles, polyethylene bottles cannot be used.

[0022] The effect of this embodiment: since 1995, Zhaixi Orchard in Rushan Town, Rushan City, Qu Fruit Orchard in Yuli Town, Taiyi Orchard in Xiacun Town, Lengjiawan Sanji Orchard, Dongli Village Orchard, Tengjiazhuang Orchard, etc. The pesticide used to control pear psyllids and other pests has been used more than 10 times a year, and now it is only used 2 to 3 times a year, so that the comprehensive control effect can reach more than 98%, and the effective control period can reach more than 30 days. It is safe for humans and animals, and it is environmentally friendly and has no residues...

Abstract

The invention relates to an inorganic pesticide and a preparation method thereof, which comprises industrial soda ash, ammonium chloride, sodium chloride and sodium sulfate. %, sodium chloride is 2-4%, sodium sulfate is 1-3%, and the rest is water; the preparation method is: add each component into the reaction kettle according to the proportion, stir, the time is 20-120 minutes, the temperature The temperature is 30-160 degrees Celsius. After the reaction is completed, filter it. After the liquid medicine is transparent and clear, put it in a glass bottle or a plastic bottle. The invention has good comprehensive control effect, no residue, long control period, low cost and high safety.

Description

Technical field: [0001] The invention relates to a pesticide, in particular to an inorganic pesticide and a preparation method thereof. Background technique [0002] We know that pear psyllid, scale insect, green peach aphid, apple cotton aphid, etc. are the most difficult pests to control in agricultural and forestry production, especially pear psyllid, its nymphs above the second instar, due to the secretion of wax liquid, conventional chemicals Basically invalid or extremely poor effect, the highest control effect is only about 50%. The pear psyllid has occurred in Rushan City and even the whole country for many years. Especially since 1992, the pear psyllid has developed from a simple damage to the Chinese pear system to a serious impact on the Western pear system such as Ba pear, causing the pear leaves to fall off prematurely and the fruit to grow. Affected, the appearance quality of the fruit is seriously reduced, and it induces soot, scab, etc., seriously affecting ...
