Penoxsulam-oxadiargyl oil suspension agent and preparation method thereof

Abstract

The invention discloses a penoxsulam-oxadiargyl oil suspension agent. The oil suspension agent comprises the following components in percentage by mass: 0.1%-30% of penoxsulam, 1%-30% of oxadiargyl, 1%-20% of a dispersing agent, 0.1%-2% of a structural agent, 1%-5% of an antifreezing agent, 0.1%-1.0% of a defoaming agent, 0.1%-1% of a preservative and the balance of oil base. A weeding composition of the penoxsulam-oxadiargyl oil suspension agent can be used for effectively preventing and removing paddy field grass family, sedge family, broadleaf weeds; the using effect is obviously superior to that of independently used single herbicides; the herbicide controlling spectrum is expanded; the consumption of the herbicides is reduced; the penoxsulam-oxadiargyl oil suspension agent is low in toxicity, high in efficiency and safe to people and livestock, and is environmentally-friendly.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to the field of herbicides, and relates to a penoxsulam and oxadiazone propargyl oil suspension and a preparation method thereof. Background technique [0002] As people's awareness of environmental protection becomes stronger and more eager for high-efficiency, low-toxicity, low-residue, and environmentally-friendly pesticides, pesticide science and technology workers are working day and night to develop new varieties and new formulations of high-efficiency, low-toxicity, and environmentally friendly pesticides. [0003] Penoxsulam is a conductive herbicide, which is absorbed by stems, leaves, young shoots and roots, and then transmitted to meristems through xylem and phloem, inhibiting plant growth and causing growth points to lose chlorosis. Reddening, necrosis, and plant death in 2 to 4 weeks; this agent is a strong acetolactate synthase inhibitor, and the agent appears slowly, and it ...

AI Technical Summary

Problems solved by technology

[0005] At present, the crop safety of paddy field herbicides is limited, and the herbicidal spectrum is also limited. The use of a single herbicide alone cannot completely and effectively control the occurrence of weeds in paddy fields. Uniformity is also likely to cause residual toxicity to current crops or subsequent crops
