Abstract

The invention discloses an oxadiargyl and oxyfluorfen-containing compound suspension concentrate and a preparation method and applications thereof. The compound suspension concentrate comprises the following components: 5-30% of oxadiargyl, 5-30% of oxyfluorfen, 2-20% of a surfactant, 0-6% of a co-suspension concentrate, 0-1% of a thickening agent, 0-1% of a defoaming agent, 0-1% of a preservative, 0.5-5% of an antifreezing agent, and the balance of water for supplementing to 100%. According to the oxadiargyl and oxyfluorfen-containing compound suspension concentrate disclosed by the invention, because the components of the compound suspension concentrate have different function characteristics, after the compounded components are simultaneously applicable to paddy fields, and drug resistance of weeds is not easy to produce; the components can have complementary advantages, so that the weed killing range is expanded; the compound suspension concentrate is safe for rice, has no side effect, and has good safety for afterreap crops; and the compound suspension concentrate disclosed by the invention is an environmental-friendly water-based dosage form, and has the advantages of safe production, storage and application, small environment pollution, low production cost, easiness for packing, and the like. The compound suspension concentrate disclosed by the invention has strong affinity with the soil, the pesticide effect is increased, and the field application amount is reduced, and thus the production cost and the application cost are lowered, and the pesticide residues and environmental pollution are reduced.

Description

technical field [0001] The invention relates to an agricultural herbicide preparation, in particular to a compound aqueous suspension containing propargyl clomazone and oxyfluorfen, a preparation method and application thereof. Background technique [0002] Proporphyrinogen oxadiazone is a protoporphyrinogen oxidase inhibitor, and it is a diazolone pre-emergence and early post-emergence herbicide. It works mainly through the contact absorption of some sensitive weeds before and after the emergence of sprouts and seedlings. It is a kind of contact herbicide, which mainly works when the weeds germinate and absorb by contact. It is mainly used for weeding in paddy fields, and it is also effective for peanuts, cotton, sugarcane, etc. in dry fields; it is used for the control of barnyard grass, daughter of a daughter, paspalum, special-shaped sedge, bermudagrass, knotweed, echinacea, melon skin grass in paddy fields Wait. It can also be used to control annual grass weeds and br...
