Abstract

The invention discloses a weeding composition containing oxaziclomefone, clomazone and pyrazosulfuron-ethyl, the effective components of the weeding composition comprise the oxaziclomefone, the clomazone and the pyrazosulfuron-ethyl, and the weight ratio of the oxaziclomefone to the clomazone to the pyrazosulfuron-ethyl is (1-30):(1-50):(1-40). The dosage form of the weeding composition is one of a dispersed oil suspending agent, missible oil, a suspending agent, a microemulsion, an emulsion in water, a suspoemulsion, soluble powder, water dispersible granules and effervescent granules. The weeding composition can be applied to prevention and removal of annual weeds in rice transplanting fields. The combination effect of the composition shows an obvious synergistic effect within a certain ratio range, the weeding effect of the composition is obviously improved compared with that of each single agent or binary compound agent, the use dosage of pesticides is reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to a pesticide herbicidal composition and its application field, in particular to a herbicidal composition comprising oxazicone, clomazone and pyrazosulfuron-methyl. Background technique [0002] Oxaziclomefone (Oxaziclomefone), Chinese common name: Qubai'an; RYH-105; Oxaziclomefone, molecular formula is C20H19Cl2NO2, this preparation belongs to organic heterocycles, is a systemic herbicide for paddy fields, mainly composed of heterocyclic Absorbed by the roots and bases of stems and leaves of grasses, the stems and leaves of weeds will turn green and stop growing after contacting the agent, until they die. Acute oral: >5000mg / kg; acute percutaneous: >2000mg / kg, can control barnyardgrass, ditch Chickweed, Qianjinzi, special-shaped sedge and other weeds have good dispersibility, and the weeding operation is labor-saving, and the bottle can be directly shaken from the bottle. [0003] Clomazone, other Chinese names: clomazone...
