Embodiment 140

[0054] Example 140%% Compound A1 Cyhalofop-methyl (8:32) suspension concentrate

[0055] According to the formula requirements, 8 parts of compound A1, 32 parts of cyhalofop-ester, 4 parts of Nongru 0201B, 4 parts of sodium salt of alkylnaphthalene sulfonic acid condensation polymer, 2 parts of dispersant SP-2728, 2 parts of Nongru 1601# , 0.2 parts of xanthan gum, 0.5 parts of white carbon black, 5 parts of ethylene glycol, make up to 100% with water, add them to the mixing tank in turn and mix them, first go through high shear for coarse crushing and homogenization, and then pump them into the sand Carry out fine grinding in the mill, and use a particle size distribution instrument to detect the particle size of the sand-milled material. When the particle size reaches the standard requirement, filter to obtain 40%% compound A1·cyhalofop-ethyl suspension concentrate.

Embodiment 240

[0056] Example 240% Compound A1 Cyhalofop-methyl (10:30) suspension concentrate

[0057] According to the formula requirements, 10 parts of compound A1, 30 parts of cyhalofop-ester, 4 parts of sodium methylnaphthalenesulfonate formaldehyde condensate, 4 parts of Nongru 0201B, 4 parts of sodium salt of alkylnaphthalenesulfonic acid condensation polymer, 2 parts Nongru 1601#, 0.2 parts of xanthan gum, 0.5 parts of white carbon black, 5 parts of ethylene glycol, make up to 100% with water, add to the mixing tank in turn and mix, first go through high shear for coarse crushing and homogenization, and then Pump it into a sand mill for fine grinding, and use a particle size distribution meter to detect the particle size of the sand-milled material. When the particle size reaches the standard requirement, filter it to obtain 40% compound A1·cyhalofop-ethyl suspension concentrate.

Embodiment 330

[0058] Example 330% Compound A1 Cyhalofop-methyl (10:20) Suspension Concentrate

[0059] According to the formula requirements, mix 10 parts of compound A1, 20 parts of cyhalofop-ethyl, 5 parts of dispersant SP-28F, 3 parts of wetting agent SP-SC3266, 4 parts of Nongru 0201B, 2 parts of Nongru 1601#, 0.1 part of yellow Raw rubber, 0.5 parts of white carbon black, 5 parts of ethylene glycol, and water to make up to 100%, are added to the mixing tank in turn for mixing, first undergo high shear for coarse crushing and homogenization, and then pumped into the sand mill for Finely grind, and use a particle size distribution instrument to detect the particle size of the sand-milled material. When the particle size reaches the standard requirement, filter to obtain a 30% compound A1·cyhalofop-ethyl (10:20) suspension concentrate.

Abstract

The invention relates to a new herbicide composition and its application method, belonging to the technical field of agricultural herbicides. The composition is composed of component A and component B, and the weight ratio between the two components of component A and component B is 1:100 to 100:1; component A is selected from compounds shown in general formula I, and component Part B is selected from the group consisting of cyhalofop-methyl, propanil, cyclafen, bispyriben or saflufenacil. The herbicide composition is mainly used for controlling broad-leaved weeds, gramineous weeds and sedges in paddy fields, and has obvious synergistic effect compared with the herbicidal effect of each component when used alone.

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] The publication number is CN102464611A, which discloses a herbi...
