Problems solved by technology

[0005] Acetochlor, pretilachlor, butachlor and other herbicides can be used as closed herbicides in paddy fields or early treatment after transplanting, and have high control activity against weeds in paddy fields, but these herbicides are easy to produce pesticides on rice seedlings. Harm, the use is subject to certain restrictions

Embodiment 131

[0062] Example 131% Compound A1. Saponin (1:30) dispersible oil suspension

[0063] According to the formula requirements, mix 1 part of compound A1, 30 parts of saponin, 5 parts of agricultural milk 0201B, 2 parts of agricultural milk 1601#, 3 parts of dispersant SP-OF3468, 2 parts of dispersant SP-3472B, 4 parts of agricultural milk 500 #, Methyl oleate is supplemented to 100% and then added to the mixing tank for mixing. First, it is coarsely crushed and homogenized by high shear, and then pumped into a sand mill for fine grinding. The sand-milled material is detected by a particle size distribution analyzer When the particle size reaches the standard requirement, it is filtered to obtain 31% compound A1·sapine phosphorus dispersible oil suspension.

Embodiment 233

[0064] Example 233% Compound A1. Saponin (3:30) dispersible oil suspension

[0065] According to the formula requirements, mix 3 parts of compound A1, 30 parts of saponin, 2 parts of agricultural milk 1601#, 4 parts of dispersant TANEMULSOD, 2 parts of dispersant TANEMUL1736, 4 parts of agricultural milk 500#, 2 parts of white carbon black, oleic acid Make up to 100% of the methyl ester and then add it to the mixing tank for mixing. First, it will be coarsely crushed and homogenized by high shear, and then pumped into the sand mill for fine grinding. After the particle size reaches the standard requirement, it is filtered to obtain 33% compound A1·saponin dispersible oil suspension.

Embodiment 324

[0066] Example 3 24% compound A1. Saponin (4:20) dispersible oil suspension

[0067] According to the formulation requirements, mix 4 parts of compound A1, 20 parts of saponin, 10 parts of dispersant SP-OF3468, 2 parts of dispersant SP-3472B, 2 parts of agricultural milk 1601#, 3 parts of agricultural milk 500#, and 2 parts of white carbon Add black and methyl oleate to 100% and add them to the mixing tank for mixing. Firstly, they are coarsely crushed and homogenized by high shear, and then pumped into a sand mill for fine grinding. The sand-milled materials are detected by a particle size distribution analyzer. When the particle size reaches the standard requirement, filter to obtain 24% compound A1·sapylphos dispersible oil suspension.

Abstract

The invention relates to a novel herbicidal composition and an application method thereof, and belongs to the field of agricultural herbicides. The herbicidal composition comprises effective components namely a component (A) and a component (B); wherein the component (A) is represented by the formula (I), the component (B) is one or more of anilofos, oxyfluorfen, alachlor, acetochlor, pretilachlor, propisochlor, metolachlor, butachlor, and atrazine, and the weight ratio of the component (A) to the component (B) is 1:30-30:1. The herbicidal composition is mainly used to prevent and remove broadleaf weeds, grassy weeds, and nutgrass flatsedge in rice field, and has a prominent synergetic effect on removing weeds, compared with that of the single components.

Description

technical field [0001] The invention belongs to the technical field of agricultural herbicides, and in particular relates to a herbicide composition for paddy fields and its application. Background technique [0002] Rice is an important food crop with a wide range of planting areas and diverse growth environments. Field weeds often grow mixedly, including a variety of annual or perennial grasses, broad-leaved weeds and sedges. At present, there is no single herbicide that can completely eliminate these weeds at the same time. At the same time, with the increase in the frequency and dosage of single-agent herbicides used in rice fields, problems such as the safety of rice, the impact on the soil environment, the strengthening of weak weeds, and the control of drug-resistant weeds have gradually emerged. Mixing herbicides with different action mechanisms is an effective way to solve the above problems. [0003] Publication No. WO / 2012 / 059050 discloses a compound with extrem...
