Problems solved by technology

The common characteristics of amide herbicides are: ①Almost all varieties are special herbicides for controlling annual grass weeds, and their control effect on broad-leaved weeds is poor
②Most varieties are soil treatment agents, which are mainly applied after crops are sown and before sprouts to prevent young shoots of annual weeds; while some varieties, such as propanil, can only be treated with stems and leaves, and are inactive when applied to the soil
③Soil-treated varieties have a shorter duration in the soil, generally 1 to 3 months
At present, there is no report on the ternary compound composition and application of butachlor, clomazone and pyrimethan

Abstract

The invention relates to a herbicide composition, and especially relates to a herbicide composition used for controlling paddy field weed, wherein amides, clomazone, and (E)-pyriminobac-methyl are taken as the active components of the herbicide composition at a preferable weight ratio of (15-66): (1-7): (0.5-3), and the amount of the active components in the herbicide composition ranges from 22.5 to 85% preferably. The combination of the herbicide composition is reasonable; weed control spectrum is widened; controlling effect on worst weed is improved; the using amount of single-component herbicide is reduced; herbicide application times are reduced; intervals are prolonged; prevention cost is reduced; generation of drug resistance of weed on the three active components is delayed; the herbicide is safe for paddy rice, and is an ideal herbicide.

Description

Technical field [0001] The invention belongs to the technical field of compound pesticides, and relates to a herbicide composition, in particular to a paddy field herbicide composition containing amide herbicides, clomazone and saxifen. It is suitable for the control of weeds in paddy fields. Background technique [0002] Rice is one of the world’s three major food crops, and it is also my country’s largest food crop. The population of my country whose main food is rice accounts for about 65% of the total population. Rice planting area and annual output are second only to India, and are ranked in the world’s food The crop is second. my country is the country with the largest population in the world. Rice is the main food in my country. The production of rice plays a vital role in my country's food security and has a significant impact on the physical fitness of the people. [0003] Amide herbicides are a new type of herbicide with the fastest development, high herbicidal effect an...
