Efficient herbicide used for celery and spinach vegetables

Abstract

The invention discloses an efficient herbicide used for celery and spinach vegetables. The efficient herbicide consists of the following raw materials in parts by weight: 100 to 200 parts of benthiocarb, 10 to 50 parts of metribuzin, 20 to 30 parts of paraquat, 5 to 10 parts of haloxyfop-R-methyl, 3 to 5 parts of an LX pesticide suspension agent, 2 to 6 parts of an NNO pesticide dispersion agent,1 to 3 parts of an agricultural pesticide emulsifier 700, 5 to 10 parts of kaolin and the balance of deionized water. The efficient herbicide is mainly applied to killing weeds in rice seedling beds,rice fields and direct seeding rice fields of celery and spinach vegetables, has an obvious spread spectrum synergetic effect, high safety and herbicidal activity, and can kill various monocotyledonous and dicotyledonous weeds through one-time application. When the herbicide is used, the herbicide dose is reduced, the number of times of herbicide application is reduced, the environment is improved, and the safety of food is improved. The herbicide is in accordance with the development trend of herbicides in China.

Description

technical field [0001] The present invention relates to a herbicide. Background technique [0002] There are 30,000 species of weeds widely distributed in the world, and about 1,800 species cause damage to crops to varying degrees every year, and the annual crop yield reduction due to weed damage is as high as 9.7%. Herbicides refer to agents that can completely or selectively kill weeds, also known as herbicides, and are a class of substances used to eliminate or inhibit plant growth. Commonly used herbicides are organic compounds, which can be widely used to prevent and control harmful plants such as weeds, shrubs, and trees in farmland, orchards, flower nurseries, grasslands and non-cultivated land, railway lines, rivers, reservoirs, warehouses, etc. Over the past century, herbicides have been used to effectively control many weeds, but the extensive use of chemical agents has also caused a series of problems, such as the emergence of herbicide-resistant weed plants, soi...

AI Technical Summary

Problems solved by technology

Over the past century, herbicides have been used to effectively control many weeds, but the extensive use of chemical agents has also caused a series of problems, such as the emergence of herbicide-resistant weed plants, soil pollution, water quality degradation, and the use of non-weeds. Hazards of grass organisms (especially humans and animals), etc.

[0003] Most of the high-efficiency herbicides currently used for celery and spinach vegetables are mostly kill-type or contact-type herbicides, and the herbicide effect is limited by the types of crops and weeds, which greatly affects the herbicide effect
