Problems solved by technology

[0003] Dry suspension concentrate is used as an auxiliary agent of butazone, and the current dry suspension concentrate of butazone is not ideal for weed treatment in practical applications. Usually, the effect of the medicine takes a long time, and the duration is not enough, and the degree of cleaning is not enough. And the dust floating during the spraying operation will cause certain safety hazards to the sprayers.

Abstract

The invention discloses a butroxydim dry suspending agent and a preparation method thereof. The butroxydim dry suspending agent is prepared from, by weight, 10-90 parts of butroxydim, 3-12 parts of asurfactant, 2-8 parts of a defoaming agent, 4-8 parts of a dispersing agent, 2-18 parts of a disintegrating agent and 2-4 parts of a chelating agent, with the balance being a filler. The butroxydim dry suspending agent prepared by the method disclosed by the invention is excellent in removal effect on various weeds in a crop field, quick in pesticide effect and long in lasting time, has a very high popularization value, is convenient to transport and store, and has high adaptive capacity.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a dry suspension concentrate of butazone and a preparation method thereof. Background technique [0002] Butafenone, chemical name 5-(3-butyryl-2,4,6-trimethylphenyl)-2-[1-(ethoxyimino)-propyl]-3-hydroxy-cyclohexyl- 2-en-1-one is an off-white powdery solid with a melting point of 80.8°C. It is a post-emergence herbicide and is mainly used in legume crops (broad beans, peas, chickpeas, broad beans, lentils, lupins), pastures, Control grass weeds such as annual rye, wild oats, brome, barley grass, wheat grass, oat grass, barnyardgrass and foxtail in alfalfa, flax, rape, cotton, sunflower, soybean fields and peanut fields; [0003] Dry suspension concentrate is used as an auxiliary agent of butazone, and the current dry suspension concentrate of butazone is not ideal for weed treatment in practical applications. Usually, the effect of the medicine takes a long time, and the dura...
