Problems solved by technology

At present, the 0.3% matrine water agent produced by some manufacturers, using it as an insecticide, has a control effect of more than 90% on cabbage caterpillars, while using it as a fungicide, the control effect is not high, and the control effect on vegetable diseases Less than 50%, and the drug effect time is also slow
The reason for the low bactericidal and preventive effect of matrine aqueous solution is that the spreading, wetting and penetrating properties are poor, and it is unstable after adding Nongru hyperosmotic agent

Abstract

A 0.3% emulsified sophocarpidine oil as bactercide for preventing and eliminating the frosty mildew of vegetable is prepared from 3 Chinese-medicinal materials including flavescent sophora root, rhizoma veratri, etc. calcium lime and water through proportioning, pulverizing, biochemical processing, extracting in alcohol, concentrating and adding emulsifier. Its advantages are sure effect, quickly taking its effect, low poison, no residual and no environmental pollution.

Description

technical field [0001] The invention relates to a processing method of 0.3% matrine emulsifiable oil fungicide, which belongs to the processing method of plant pesticides. Background technique [0002] For a long time, chemical pesticides have been the mainstay in the prevention and control of vegetable and fruit pests. The residues of chemical pesticides not only endanger human health, but also cause damage to the ecological environment. Thus, plant pesticides are attracting more and more attention. At present, the 0.3% matrine water agent produced by some manufacturers, using it as an insecticide, has a control effect of more than 90% on cabbage caterpillars, while using it as a fungicide, the control effect is not high, and the control effect on vegetable diseases Less than 50%, and the drug effect time is also slower. The reason for the low bactericidal effect of the matrine aqueous solution is that the spreading, wetting and penetrating properties are poor, and it is ...
