Embodiment 1

[0031] The composition and weight percent of the carbendazim microemulsion are: 0.8% carbendazim, 5.8% chloroform, 4.0% acetic acid, 17.7% emulsifier HSH, 8.9% agricultural milk 0204, 13.3% methanol, The rest is deionized water.

Embodiment 2

[0033] The composition and weight percentage of the carbendazim microemulsion are: 1% carbendazim, 6.9% chloroform, 4.6% acetic acid, 16.7% emulsifier HSH, 8.3% agricultural milk 0204, 12.5% ​​methanol, The rest is deionized water.

Embodiment 3

[0035] The composition and weight percentage of the carbendazim microemulsion are: 1.6% carbendazim, 11% chloroform, 7.4% acetic acid, 22.2% emulsifier HSH, 11.1% agricultural milk 0204, 16.7% methanol, The rest is deionized water.

[0036] Although the weight percentage of each component in the formula can vary within a certain range, the preparation method is the same. Taking the preparation of 1 ton of the carbendazim microemulsion described in embodiment 2 as an example below, the preparation method is as follows in detail:

[0037]A. Weigh 98% carbendazim 10kg, chloroform 69kg (analytical pure), acetic acid 46kg (analytical pure), emulsifier HSH167kg (industrial use), agricultural milk 020483kg (industrial use), methanol 125kg (analytical pure) and deionized water 500kg; B, 69kg chloroform and 46kg acetic acid are stirred and mixed, add 10kg carbendazim former drug and continue to stir, after carbendazim is completely dissolved, discard impurities, and the filtrate is fo...

Abstract

The invention discloses Bavistin microemulsion which comprises the following components by weight percent: 0.8-1.6% of Bavistin, 5.8-11% of solvent chloroform, 4-7.4% of solvent acetic acid, 16.7-22.2% of emulsifier HSH (hydrogenated starch hydrolyzate), 8.3-11.1% of emulsifier Nongru 0204, 12.5-16.7% of co-emulsifier methanol and the balance deionized water. The invention also discloses a preparation method of the Bavistin microemulsion. The Bavistin microemulsion has the advantages of high efficiency, low toxicity, low cost, good environment compatibility and the like, and can be widely used for preventing and treating the plant diseases of various crops, fruits, vegetables and the like.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a carbendazim microemulsion and a preparation method thereof. technical background [0002] In recent years, with the development and spread of various crop diseases and insect pests, traditional chemical methods have brought a huge burden to the environment while preventing and controlling the diseases and insect pests. The restrictions on the use of organic solvents such as toluene and xylene in pesticide preparations have become increasingly strict. Although biological control has a good control effect in the laboratory, overall the field control effect is poor and the cost is high, so it cannot completely replace chemical control in the short term. The development cycle of new drugs is long and difficult, and research on new formulations of pesticides has become a hot spot in the field of pesticide research. [0003] The pesticide formulations used in my country mainly in...
