Abstract

The invention relates to a dispersible oil suspending agent containing oxadiargyl and oxyfluorfen. Effective components include the oxadiargyl and the oxyfluorfen. The dispersible oil suspending agent comprises, in weight percentage, 1%-10% of the oxadiargyl, 5%-15% of the oxyfluorfen, 10%-20% of emulsifiers, 1%-3% of dispersing agents, 1%-3% of thickening agents, 1%-3% of white carbon black, 3%-10% of stabilizers and the balance oil solvents. The dispersible oil suspending agent is a herbicide for pre-emergence treatment of rice, potatoes, sunflowers, vegetables, beetroots, orchards and the like, prevention and control effects of the dispersible oil suspending agent are remarkably higher than those of a single agent, and the insecticide resistance of weeds is reduced.

Description

technical field [0001] The invention relates to a herbicide used for preemergence treatment of rice, potatoes, sunflowers, vegetables, sugar beets, orchards, etc., in particular to a dispersible oil suspension containing propargyl oxadiazone and oxyfluorfen. Background technique [0002] At present, there is a lack of herbicides for pre-emergence treatment in China, and there is no guarantee for drug efficacy and phytotoxicity. The herbicides for pre-emergence treatment provided by the present invention can improve this domestic situation. [0003] Propyryl oxadiazone is a new type of oxadiazole nitrogen-containing heterocyclic herbicide, which can control annual and perennial gramineous barnyardgrass, Cyperaceae special-shaped sedge, cattle felt, and knotweed in broad-leaved grass , Ziping, algae Spirogyra, chrysanthemum and other weeds, in addition to killing and inhibiting fireflies, three-edge grass (flat stalk grass, Japanese foot grass, foot grass, Vitex triangular), Y...
