Description
Technical Field
The invention relates to the technical field of pesticides, and particularly relates to a dispersible oil suspending agent containing metamifop and bispyribac-sodium and a preparation method thereof.
Background
Metamifop is aryloxy phenoxy propionate herbicide, the action mechanism of which is to inhibit acetyl coenzyme A carboxylase, and the effective ingredients need to reach the target in the plant body to play the role of weeding. The solvent and the surfactant respectively play roles in softening the waxy layer of the leaf surface and opening the stomata of the plant, so that the effective ingredients enter the plant body to play a role. The weeding composition mainly prevents and removes most annual gramineous weeds such as barnyard grass, moleplant seed, large crabgrass and eleusine indica in transplanting and direct seeding fields, and the prevention and removal effect reaches over 95 percent.
The bispyribac-sodium is a benzoic acid herbicide, is a high-activity Acetolactate Synthase (ASL) inhibitor, can be quickly absorbed by stems and leaves of weeds after being sprayed on the weeds, and is conducted to the whole plants to inhibit the growth of plant meristems, so that the weeds are killed, and the bispyribac-sodium is high-efficiency, broad-spectrum and low in dosage. The bispyribac-sodium can effectively prevent and kill barnyard grass and other gramineous weeds in the rice field, and can also control most broadleaf weeds, some cyperaceae weeds and barnyard grass which generates resistance to other herbicides.
The metamifop and the bispyribac-sodium are mixed according to a proper proportion, so that the pesticide effect can be improved, the dosage can be reduced, the economic cost can be saved, and the residue of the pesticide in the environment can be reduced. Meanwhile, the weed resistance can be delayed, the service life of the herbicide is prolonged, the pesticide effect time can be prolonged by adding the auxiliary agent, and the weeding effect in a high-temperature or low-temperature environment is improved.
The dispersible oil suspending agent (OD) has the advantages of environmental friendliness, high drug effect, no need of barrel mixing auxiliary agent and convenient use, but the prior OD product related to metamifop and bispyribac-sodium generally has the defects of high long-term storage decomposition rate, poor stability and high cost, and can cause the problems of layering, bottom formation and the like in the long-term storage or transportation process.
