Embodiment 1

[0020] Example 1 20% triclopyr dimethylamine saline solution

[0021] Triclopyr 20%; Dimethylamine 5%; Tallowamine 5%; Polyoxyethylene alkylamine 6%; Deionized water to make up 100%.

[0022] The preparation method is as follows: Dimethylamine is both a salt-forming agent and a pH regulator. First add dimethylamine into deionized water, then gradually add chlorpyrrole under stirring condition, stir while adding, heat up to make clopyroxy acetic acid completely dissolve. Adjust the pH to 6.0. Cool down to 40°C, add surfactant polyoxyethylene alkylamine and tallow amine, stir evenly to obtain 20% triclopyr dimethylamine saline solution.

Embodiment 2

[0023] Example 2 30% triclopyr ethylenediamine saline solution

[0024] Triclosan 30%; ethylenediamine 15%; fatty amine polyoxyethylene ether 6%; polyoxyethylene alkylamine 6%; deionized water to make up 100%.

[0025] The preparation method is: Ethylenediamine is both a salt-forming agent and a pH regulator. First add ethylenediamine into the deionized water, then gradually add chlorpyroxyacetic acid under the condition of stirring, stir while adding, and heat up to make the clopyroxyacetic acid completely dissolve. Adjust the pH to 6.0. Cool down to 40°C, add surfactant fatty amine polyoxyethylene ether, polyoxyethylene alkylamine, stir evenly to obtain 30% chlorpyroxy ethylenediamine saline solution.

Embodiment 3

[0026] Example 3 40% Triclopyr Triisopropanolamine Saline

[0027] Triclopyr 40%; Triisopropanolamine 20%; Fatty amine polyoxyethylene ether 10%; Polyoxyethylene alkylamine 7%; Ethylenediamine 1%, deionized water to make up 100%.

[0028] The preparation method is as follows: firstly add triisopropanolamine into deionized water, then gradually add clopyroxy acetic acid under stirring condition, stir while adding, and heat up to dissolve clopyroxy acetic acid. Adjust the pH to 6.0 with an appropriate amount of pH regulator ethylenediamine. Cool down to 40°C, add surfactant fatty amine polyoxyethylene ether, polyoxyethylene alkylamine, stir evenly to obtain 40% clopyroxytriisopropanolamine saline solution.

Abstract

The invention relates to a weeding composition, which comprises, by mass, 1-60% of triclopyr raw pesticide, 1-20% of a salt forming agent, 1-30% of a surfactant and the balance of a filler. Accordingto the invention, the composition can obviously improve the deposition and penetration effects of the drug on the surface of plants, and enhance the ability of the drug to penetrate through organellemembrane structures, so that the composition has higher weeding activity than the existing triclopyr and butoxyethyl triclopyr.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a herbicide containing triclopyr and a preparation method thereof. Background technique [0002] Triclopyr is a systemic conduction type selective herbicide, which can be absorbed through the leaves and roots of plants, conduct in plants, and can be used to control broad-leaved weeds. Triclopyr is slightly soluble in water and it is difficult to make a water solution. Therefore, in the actual use process, its ester will be used to expand the range of dosage forms. For example, butoxyethyl clopyroxyacetic acid and triethylamine salt of clopyroxyacetic acid have been registered. Among the existing registered products, there is no product in which triclopyr is salted with polyvalent organic amines. [0003] The inventors of the present application have found through research that the dimethylamine, ethylenediamine, triisopropanolamine, and tetraethylenepentamine of chlorpyroxy ...
