Abstract

The invention discloses a weeding composition containing oxaziclomefone and cyhalofop-butyl. The weeding composition contains effective components, namely xaziclomefone and cyhalofop-butyl, and the balance of pesticide adjuvants. The parts-mass ratio of xaziclomefone to cyhalofop-butyl is (15:1) to (1:15). 2-60 percent by weight of the total mass of xaziclomefone and cyhalofop-butyl is in the composition. During the actual application, the weeding composition can be used for preparing one of a suspending agent, wettable powder and a water dispersible granule, can effectively control annual grassy weeds of paddy fields, has a pesticide effect superior to that of singly used oxaziclomefone and cyhalofop-butyl obviously, improves the weeding effect, and expands the weed control spectrum.

Description

technical field [0001] The invention relates to a herbicidal composition containing oxaziclozone and cyhalofop-methyl, the active ingredients of which are oxaziclozone and cyhalofop-methyl, which is used for controlling annual grass weeds in paddy fields. Background technique [0002] Chemical weeding is one of the main means of weed control in agriculture, which has the advantages of high efficiency, time saving and labor saving. Grass weeds in paddy fields mainly include barnyardgrass and chinensis, etc. The use of single oxazicone and cyhalofop-ethyl cannot solve the control of barnyardgrass and chinensis in paddy fields at one time, and it will show some defects and limitations sex. Increasing the dosage will cause adverse effects on crops and the environment. The combination of different species of compounds can improve the actual effect, expand the weeding spectrum, save time and labor, reduce the dosage of a single species, and delay weed resistance.
