Plant herbicide

Abstract

The invention relates to the technical field of pesticides, in particular to a plant herbicide. The plant herbicide is prepared from the following materials in parts by weight: 3-12 parts of 9-carbonyl-10,11-dehydroageraphorone, 5-12 parts of juglone, 10-18 parts of a ragweed extract, 6-16 parts of a carpesium cernuum extract, 1-8 parts of azadirachtin, 1-4 parts of triacontanol, 0.5-3 parts of pyromellitic sodium and 1-4 parts of an emulsifying agent. The plant herbicide provided by the invention has the characteristics of rapid response, obvious weeding effect, no pesticide residue, and lowpossiblity of causing drug resistance and accumulation of toxic and side effects.

Description

【Technical field】 [0001] The invention relates to the technical field of pesticides, in particular to a plant herbicide. 【Background technique】 [0002] With the gradual advancement of my country's modern agriculture and the transformation of large-scale and intensive planting, the demand for herbicides has gradually increased, and the amount of herbicides has increased significantly, and the proportion of herbicides in pesticide products has shown an increasing trend. The current registered herbicide products in my country have the following characteristics: First, the active ingredients of the registered products are mainly old products with a high degree of similarity. The proportion of newly created herbicide products is relatively small; second, the development trend of diversification of dosage forms is not obvious, and the number of registered products with EC as dosage form has remained high in the past 6 years. Third, the number of production enterprises is large an...

Problems solved by technology

Third, the number of production enterprises is large and scattered. Dozens or even hundreds of enterprises with the same active ingredient herbicide have obtained registration and production qualifications in China; fourth, the registered products on different crops are uneven, and those registered in soybean, citrus, and tea The number of products is large, while the number of registered products of crops such as vegetables is relatively small, or even no medicine is available

Issues such as few created products, slow update of active ingredients, unbalanced development of dosage forms, serious homogeneity of product registration, etc. are more prominent

In addition, due to the long-term, excessive, and repeated use of herbicides, the succession of weed communities, the increase in the proportion of difficult-to-control weeds, and the growing problem of weed resistance

[0005] At present, due to the fact that botanical herbicides are still in the primary development stage in my country, some pharmacological mechanisms are still unclear and the production process is not mature enough, botanical pesticides generally have the problem of "delayed action", which is not in line with the "speed" psychology of farmers today. To adapt, most farmers still choose to use highly toxic and high residue chemical pesticides to kill weeds. In addition, the current high cost of botanical pesticides also restricts their popularization and application
