Abstract
The invention relates to the technical field of pesticides, and particularly relates to a weeding composition and a herbicide. The weeding composition consists of 0.1 to 80 parts of prodiamine and 0.1 to 90 parts of diuron by weight. The invention has obvious synergistic effect on the control effect of the ammonia trifluralin and the diuron on weeds in cotton fields and soybean fields through various different action modes, is obviously superior to the effect of preparations such as ammonia trifluralin single dose and diuron single dose, can effectively improve the control effect on the weeds in the cotton fields and the soybean fields while effectively reducing the dosage of different preparations such as the ammonia trifluralin and the diuron, can delay the resistance of the ammonia trifluralin and the diuron to the weeds, can reduce the production cost, and is a novel, high-efficiency and low-risk herbicide composition.
Description
Technical Field
The invention relates to the technical field of pesticides, and relates to a weeding composition and a herbicide.
Background
According to investigation, the weeds harmful to crops such as cotton, soybean and the like in China are hundreds of, the yield loss of the crops such as the cotton, the soybean and the like caused by the weeds in every year is 10-30%, and can be more than 50% in severe cases, such as cowhells, crabgrass, green bristlegrass, carignane, purslane, redroot amaranth, quinoa, abutilon, black nightshade and the like, in the weed control process, long-term excessive use of chemical pesticides causes serious agricultural non-point source pollution, influences on the safety of ecological environment, increases the resistance of the weeds and reduces the control effect. The reasonable use of the mixed medicament is one of the important ways of improving the medicament effect and delaying the resistance. Therefore, the method has important economic value significance in screening out a novel high-efficiency and low-risk herbicide formula.
Prodiamine is a dinitroaniline herbicide that acts primarily to inhibit spindle formation and thus cell division, root system and shoot growth. The selective pre-emergence soil treatment agent mainly prevents and removes annual weeds in non-cultivated land through the absorption of germs and embryonic axis of the weeds.
Diuron is a substituted urea herbicide, belongs to an internal absorption conduction type herbicide, has certain contact activity, can be absorbed by roots and leaves of plants, mainly absorbs the roots, and the roots of weeds transmit the herbicide to overground leaves after absorbing the herbicide, and transmit the herbicide to the surroundings along veins of the leaves to inhibit the Hill reaction of photosynthesis, so that the leaves are green, the tips and the edges of the leaves are faded, and then the leaves are yellow and withered.
At present, no herbicidal composition consisting of the trifluralin and the diuron is reported.
