Problems solved by technology

[0005] At present, herbicides are limited by the safety of crops, and the herbicide spectrum is also limited. Using a single herbicide alone cannot completely effectively control the occurrence of weeds in crops. Long growth, excessive dosage or uneven application will easily cause residual toxicity to surrounding crops or subsequent crops

Abstract

The invention discloses a weeding composition containing dithiopyr and halosulfuron-methyl, and belongs to the technical field of pesticides. The weeding composition takes the dithiopyr and the halosulfuron-methyl as effective components, and the mass ratio of the dithiopyr to the halosulfuron-methyl is (1-9): (1-9). The herbicidal composition prepared by compounding dithiopyr and halosulfuron-methyl is applied to paddy fields, the weed control effect of the herbicidal composition is obviously superior to the sum of theoretical effects of a single agent, the herbicidal activity is improved under the condition that the dosage of effective components is reduced, and the herbicidal composition has a super-superposition effect.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a herbicidal composition containing dithiopyr and chlorpyrazosulfuron-methyl. Background technique [0002] In crop cultivation, it is extremely important to protect crops by controlling weeds that inhibit the growth of crops. In order to reduce damage such as crop growth or yield loss caused by weeds growing in cultivated areas, researchers have developed active herbicidal substances that can effectively control weeds and are safe for crops. These herbicidally active substances for controlling weeds growing in the cultivated area of ​​specific crops preferably have high herbicidal activity and broad herbicidal spectrum, and are safe to the environment and crops. [0003] Dithiopyr is a pyridine carboxylic acid herbicide. Used for weeding in paddy fields and lawns, applying 0.06kg(a.i.) / ha pre-emergence and 0.12kg(a.i.) / ha post-emergence (barnyardgrass 1.5 leaf s...
