Abstract

The invention relates to novel microemulsion type herbicide and a preparation method thereof and belongs to the technical field of production of pesticides. The novel microemulsion type herbicide is prepared from the following components in parts by weight: 10-20 parts of nipagin ester, 10-20 parts of bispyribac-sodium, 15-25 parts of citric acid, 10-20 parts of cyhalofop-butyl, 10-20 parts of xanthan gum, 10-30 parts of glycerinum and 60-70 parts of water. The preparation method of the novel microemulsion type herbicide comprises the following steps: uniformly mixing the components in parts by weight, regulating the pH value to be 6.0-7.0, carrying out spray drying at the temperature of 50-80 DEG C, so as to obtain powder, sealing, and storing; the novel microemulsion type herbicide is easy to preserve, easy to use, good in stability, high in activity and lasting in effect and has spectral property and no adverse effect on crops.

Description

technical field [0001] The invention relates to a herbicide and a preparation method thereof, in particular to a novel microemulsion type herbicide and a preparation method thereof, and belongs to the technical field of pesticide production. Background technique [0002] Herbicides are agents that can completely or selectively kill weeds. Sodium chlorate, borax, arsenic acid, trichloroacetic acid have a deadly effect on any kind of vegetation, but because of their residual effects, they should not be used in the field. Selective herbicides, especially derivatives of nitrophenols, chlorophenols, and carbamic acids, are mostly effective. The development of herbicides in the world is gradually stabilizing, mainly developing varieties with high efficiency, low toxicity, broad spectrum, and low dosage, and disposable treatment agents with little environmental pollution have gradually become the mainstream. [0003] The formulation design of herbicide microemulsion is of great s...
