Problems solved by technology

Due to the relatively single herbicidal spectrum of Hedazhuang, the use of dichlorpyrid for successive years has led to changes in the weeds and weeds in rice fields, and at the same time increased the resistance level of barnyard grass, resulting in a downward trend in the use of Hedazhuang in Northeast China.
In addition, if the use exceeds the normal recommended dose, it will cause damage to the rice
[0008] At present, herbicides in paddy fields are limited by their safety and herbicidal spectrum. Single use of one herbicide cannot solve the problem of weeds in paddy fields. In recent years, the population of resistant weeds in paddy fields has become more and more obvious.

Embodiment 1

[0023] Example 1 0.1% formula (A) compound + 1% Wodazhuang EC

[0024] Compound of formula (A) 0.1%

[0025] Wo Dazhuang 1%

[0026] Dimethylformamide 3%

[0027] Cyclohexanone 1%

[0028] Calcium dodecylbenzenesulfonate 5%

[0029] Fatty alcohol polyoxyethylene ether 3%

[0030] Castor Oil Ethoxylates 1%

[0031] Sorbitol ethoxylate 1%

[0032] Solvent oil make up to 100%

[0033] The specific processing steps of the dispersible oil suspension concentrate of the composition are as follows: mix solvent naphtha, cyclohexanone and dimethylformamide according to the above formula, then add the compound of formula (A) and Wodazhuang to dissolve it completely, and then add Stir the emulsifier evenly to prepare the emulsifiable concentrate containing the compound of formula (A) and Croda officinale according to the present invention.

Embodiment 2

[0034] Example 2 0.5% formula (A) compound+1% Woda Zhuang aqueous emulsion

[0035] Formula (A) compound 0.5%

[0036] Wo Dazhuang 1%

[0037] Mineral spirit 3%

[0038] Tetrahydrofuran 4%

Abstract

The invention relates to a herbicide composition containing a utilization formula (A), a derivative thereof and ordram. The herbicide composition has a synergistic interaction effect, and the mass ratio of the utilization formula (A) and agricultural salt or ester to the ordram is preferably (5 to 200)-(100 to 100).

Description

technical field [0001] The invention belongs to the field of pesticide herbicide compounding, and specifically relates to a compound containing 4-amino-3-chloro-6-(4-chloro-2fluoro-3-methoxybenzyl)-5-fluoropyridine-2 - A herbicide composition compounded with carboxylic acid or its derivative and Crodazhuang and its application. Background technique [0002] Contains 4-amino-3-chloro-6-(4-chloro-2fluoro-3-methoxybenzyl)-5-fluoropyridine-2-carboxylic acid or its derivatives, developed by Dow AgroSciences Novel aryl picolinate herbicides. The present invention selects its utilization formula (A) and its agricultural salt or ester to be compounded with Woda Zhuang, and its utilization formula A is as follows: [0003] (Formula A). [0004] Formula (A) and its agricultural salts or esters are systemic herbicides that can be absorbed through leaves and roots, conduct through xylem and phloem and accumulate in the meristematic tissues of weeds to exert herbicidal activity . ...
