Problems solved by technology

[0004] There are many deficiencies in the use of bicyclic sulcotrione and bensulfuron-methyl as a single agent, the herbicidal spectrum is not wide enough, some weeds cannot be controlled, and the cost of using a single agent is relatively high. , dosage, operation, etc. are difficult to control, which may lead to inappropriate medication and affect crops

Abstract

The invention discloses a paddy field binary compound herbicide which is characterized by comprising the following raw material components by weight: 15-25 parts of benzobicylon, 3-8 parts of bensulfuron methyl, 2-15 parts of surfactants, 3-10 parts of antifreeze agents, 0.1-0.3 part of preservatives, 0.1-1 part of thickening agents, 0.1-0.8 part of defoamers, and 1-15 parts of disintegrating agents, the balance being filling materials. The weight ratio of the benzobicylon to the bensulfuron methyl is 13.5-22.5:4.53-4.94. The formula contains special carriers, is long in lasting period, and improves the paddy safety; the herbicide of the invention has special effect on annual gramineous weeds, broad-leaf weeds and cyperaceae weeds, and has significant inhibition effect on perennial weeds. Ideal weeding effect can be achieved after application once, and thus the application cost is decreased greatly.

Description

technical field [0001] The invention belongs to the field of agricultural plant protection, in particular to a binary compound herbicide for paddy fields. Background technique [0002] At present, there are mainly several planting methods for rice: transplanting, throwing seedlings, direct seeding, and machine transplanting. With the development of my country's agriculture in the direction of mechanization, scientization, and industrialization, the use of medicines and planting methods has changed year by year, and weeds in paddy fields have frequent occurrences, serious damage, and increased resistance year by year. There are many kinds of herbicides on the market that specifically control grass, broad-leaved, and sedge weeds in rice fields, but the same herbicide can effectively control several types of weeds at the same time. In practice, there are still relatively few . Pesticide compound preparations used for chemical weeding in paddy fields are currently on the marke...
