The novel rice field weeding composition provided by the invention has a good weeding effect, high safety, long efficacy time, a wide weeding range and a low cost.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a novel paddy field herbicide composition. Background technique [0002] With the development of agricultural application technology, the rice planting method has changed from the past water seedling transplanting to the dry cultivation floppy disk throwing planting, and has developed to the current direct sowing (live broadcasting) of rice seeds. At present, the planting area of ​​live broadcast fields is large and increasing rapidly. Taking Hunan as an example, according to incomplete statistics, the area of ​​live broadcast fields in Hunan has accounted for 76%, and some areas even reach 100%. The main technical problem in the direct seeding field is that the seeds of the direct seeding and the growth of weeds in the paddy field occur almost at the same time, and the original principle of weeding by using the difference in leaf age between seedlings and weeds is difficul...
