Abstract

The invention discloses a weeding composition capable of improving the safety of mesosulfuron-methyl. The composition comprises active ingredients mesosulfuron-methyl and weedicide safener at the weight ratio of 10:(0.1-10). The herbicide safener is added, so that the safety to crops is greatly improved compared with the safety of the mesosulfuron-methyl in which a herbicide safener is not added, the occurrence of phytotoxicity accidents can be decreased to protect the benefit of farmers, thus reducing the occurrence of social groupment petitioning events.

Description

technical field [0001] The invention relates to a herbicide composition with good safety, which belongs to the field of herbicide manufacture. Background technique [0002] Mesosulfuron-methyl is a sulfonylurea super-efficient herbicide, and its common name in English is Mesosulfuron-methyl. The toxicity of methylsulfuron-methyl is extremely low, and the acute oral and dermal toxicity LD50 to rats is greater than 5000mg / kg. It is mainly absorbed through the stems and leaves of plants, conducted through the phloem and xylem, and a small amount absorbed through the soil, inhibiting the activity of acetolactate synthase in sensitive plants, resulting in the blockage of branched-chain aminofacic acid synthesis, thereby inhibiting cell division and causing sensitive plants die. Under normal circumstances, 2-4 hours after spraying, the absorption of sensitive weeds reaches the peak, 2 days later, the growth stops, 4-7 days later, the leaves begin to turn yellow, followed by dead...
