Embodiment 1

[0013] Example 1: 10% Benthiazone-Acetochlor Suspending Concentrate

[0014] Benthiazone 2%

[0015] Acetochlor 8%

[0016] Nonylphenol polyoxyethylene ether (NP-9) (dispersion wetting agent) 8%

[0017] Propylene glycol (antifreeze) 1%

[0018] Xanthan gum (thickener) 1%

[0019] Silicone defoamer (SAG612) 2%

[0020] Water (filler) 78%

[0021] Weigh the materials according to the above weight ratio, stir and mix them evenly, and then sand them with a sand mill to obtain the product prepared according to the above ratio. , Amaranthus retroflexus and other weeds have a control effect of more than 90%, which is better than single use.

Abstract

The invention discloses a herbicide composition with broad-spectrum synergistic weeding effect. The active components of the herbicide composition are benzothiazole carfentrazone-ethyl and acetochlor, and a suspending agent or a wettable power serves as a product dosage form. The herbicide composition comprises, by weight, 1-25% of benzothiazole carfentrazone-ethyl, 1-35% of acetochlor, 2-25% of an auxiliary agent and 15-96% of a filling material. The herbicide composition is a herbicide pesticide composition, shows high-efficiency and broad-spectrum weeding performance, is mainly applied to annual weed control in corn fields and exerts no harmful effect on crops.

Description

technical field [0001] The present invention relates to a method for the preparation of herbicide compositions. Background technique [0002] Corn is the main food crop in my country, and the country's corn sown area has been stable at about 450 million mu for many years. Corn planting is widely distributed, and there are two planting methods of spring corn and summer corn. The weed community in the field varies with the local natural conditions and farming characteristics, and can be roughly divided into six weed damage areas: the northeast spring corn field weed damage area, the Huanghuai sea summer corn field weed damage area. Weeds are common in corn fields, and the main weeds are crabgrass, barnyardgrass, foxtail, goosegrass, amaranth, purslane, amaranth, Cyperus rotundum, etc. At present, chemical herbicides can be divided into killing herbicides and selective herbicides, and selective herbicides can be divided into soil treatment agents and stem and leaf treatment a...
