Abstract
The invention discloses a weeding composition containing promazine sulfometuron methyl and metamifop. The weeding composition comprises the following active components promazine sulfometuron methyl and metamifop and the balance of a pesticide assistant, wherein the ratio of promazine sulfometuron methyl to the metamifop in parts by weight is (10:1) to (1:10); the sum of the weight of promazine sulfometuron methyl and metamifop is 1%-80% of mass percentage of the composition. According to the application requirement, the weeding composition can be prepared into one of a suspending agent, an oil suspended agent, a water dispersible granule and wettable powder, and can be used for preventing and removing annual weeds of the rice paddy; the effect of the composition for preventing and removing the anneal weed of the rice paddy is obvious superior to that of each single dosage; the amount of a pesticide is reduced; and the herbicide resistance is delayed.
Description
Technical field
The present invention relates to a kind of promazine Sulfometuron Methyl that contains with the Herbicidal combinations of metamifop, be with promazine Sulfometuron Methyl with metamifop is for active ingredient, for preventing and kill off paddy field weed, especially with the paddy field annual weed that Paspalum distichum (Paspalum paspaloides), lady's-grass (Digitaria sanguinalis), bent grass (Agrostis matsumurae) are advantage weeds.
Background technology
Promazine Sulfometuron Methyl (Propyrisulfuron), is a kind of selectivity broad-spectrum herbicide, has good preventive effect to the weeds of resistance to sulfonylurea herbicide, effective to above the average age for marriage barnyard grass, nutgrass flatsedge, broadleaved herb, can foliar spray, get rid of and execute.
