Abstract

The invention discloses a herbicide and the application method thereof for weeds in a transplanted rice field. According to the characteristics of weeds in the transplanted rice field, the herbicide is obtained through reasonably screening and compounding the following herbicides with different efficacies and properties: pretilachlor, penoxsulam, bensulfuron methyl, cyhalofop-butyl, a quinoxalyloxy phenoxy propionate compound, sulfonylureas and benzobicylon, and is used in the rice field in different growth periods of rice according to different formulas and proportions, so that the weed killing effect is good, low toxicity is achieved, the weed control spectrum is expanded, the application amount is obviously reduced, the application times and application cost are reduced, the preparation of the herbicide is convenient, the storage time is longer, and the stronger practical value is achieved.

Description

technical field [0001] The invention relates to rice herbicide technology, in particular to a rice transplanting field weed herbicide and an application method thereof. Background technique [0002] Due to the low efficiency of agricultural production and the transfer of a large number of rural labor forces, the area of ​​winter slack fields has increased year by year, and weeds have grown indiscriminately in farmland, seriously threatening the safe production of rice. Due to the incomplete weeding before the cultivation of the land by most farmers, the delay in weeding after rice transplanting, and the lack of targeted herbicides in the face of complex and diverse weeds, the weeding effect is not good, and the loss of weeds in rice fields is increasing. . In recent years, the occurrence degree of rice field weed damage in our region is 3-4, which is moderately severe, and the occurrence area accounts for 100% of the rice planting area, and the rice output loss is nearly 10...
