Problems solved by technology

[0008] Although the prior art has reported a variety of herbicidal pesticide compositions developed by researchers, the control effects of these herbicides are still not satisfactory, and there are disadvantages such as large dosage and strong weed resistance.
In addition, finding suitable auxiliary or synergistic ingredients still requires people to spend / design a lot of experiments to explore
This shows that the development of new and efficient herbicidal pesticide compositions is not only an urgent need, but also faces great difficulties;

Abstract

The invention relates to a low-toxicity broad-spectrum weeding pesticide composition. The weeding pesticide composition comprises atrazine, 3,7-quinclorac-8-carboxylic acid, isothiocyanate allyl acetate, a surfactant, polyoxy-ethylidene (15) rosin ester, sodium resveratrol triphosphate, coconut oil, 3-hydroxy-4-methoxybenzoic acid, methyl 4-tert-butylbenzoate, 3-methyl-5-hydroxy-cyclopentanedione, ionic liquid, a micro-powder additive, an accelerant, sodium ethylene diamine tetracetate, gamma-aminopropyltriethoxysilane, sodium lignin sulfonate, calcium chloride and isopropanol. By virtue of the specific selection and combination of types of components of the weeding pesticide composition, excellent weed preventing and weed removing effects are achieved and the use amount of the weeding pesticide composition is greatly reduced; the weeding pesticide composition has a relatively wide industrial application value.

Description

technical field [0001] The invention relates to a pesticide, more specifically to a low-toxicity broad-spectrum herbicidal pesticide composition and its preparation method and application, belonging to the field of modern agricultural technology. Background technique [0002] With the advancement and development of modern agriculture and the expansion of planting scale, the demand for pesticides in my country is also increasing. Among them, herbicides, as a necessity in agricultural production, have attracted widespread attention. However, the use of a large amount of pesticides has brought about hidden dangers such as potential soil structure damage and increased weed resistance. In modern agricultural production, national policy orientation puts forward higher requirements on the safety and rationality of agricultural herbicides. Therefore, the development of new, high-efficiency, broad-spectrum, low-dose herbicides has become an urgent problem to be solved by pesticide r...
