The invention relates to the technical field of pesticides, in particular to a weeding composition containing
propanil and halosulfuron-methyl and application of the weeding composition. 0.1%-0.5% of
citric acid; 70-90% of
propanil master batch and the balance of halosulfuron-methyl master batch; the
propanil master batch comprises the following components in percentage by
mass: 80-95% of propanil, 3-6% of a dispersing agent A and the balance of a carrier, the halosulfuron-methyl master batch is prepared from halosulfuron-methyl, 20%-30% of a dispersing agent B and the balance of a carrier, and the adding amount of the halosulfuron-methyl is 0.625%-12.5% of the
mass of propanil. The absorption mechanism of the white
carbon black is utilized,
physical barrier of propanil and halosulfuron-methyl under the dry condition is achieved through the
jet mill, and excellent
dispersity and synergistic weeding
efficacy are achieved.
