Problems solved by technology

Glufosinate-ammonium has the following disadvantages: the control effect on some perennial tolerant plants (such as tall, lignified weeds) is poor; the control of older weeds is not complete, and older weeds are prone to resurgence
[0007] When the above pesticides are used alone, the actual control effect on non-cultivated weeds is not ideal, and weeds are prone to develop resistance
At present, there is no report about the herbicidal composition compounded by diquat and triclopyr and its application

Embodiment 1

[0057] Embodiment 1 (55% diquat triclopyr triethylamine saline solution)

[0058] Formula ratio: Diquat 10%, Triclopyr 45% Triethylamine, Lauryl Polyoxyethylene Ether 10%, Ethanol 5%, Sodium Benzoate 0.5%, Citric Acid 0.2%, Silicone defoamer 0.05 %, water up to 100%.

[0059] Add the above formula components in proportion to the reaction kettle, stir and mix evenly, and filter to obtain 55% diquat·triclopyr triethylamine saline solution.

Embodiment 2

[0060] Embodiment 2 (40% diquat · triclopyr triethylamine saline solution)

[0061] Formula ratio: Diquat 12%, Triclopyr 28% Triethylamine, Coconut Oil Fatty Acid Diethanolamide 4%, Betaine 8%, Benzoic Acid 0.15%, Ammonium Sulfate 0.5%, Isooctyl Alcohol 0.5% , water up to 100%.

[0062] The preparation method is the same as in Example 1.

Embodiment 3

[0063] Example 3 (27% Diquat · Triclopyr Aqueous Suspension Concentrate)

[0064] Formula ratio: Diquat 3%, Triclopyr 24%, Alkylphenol polyoxyethylene ether 3%, Aliphatic amine polyoxyethylene ether 5%, Phenethylphenol phosphate triethanolamine salt 4.5%, EO- PO block polyether 1.5%, propylene glycol 5%, magnesium aluminum silicate 1.2%, xanthan gum 0.15%, Kathon 0.2%, silicone defoamer 0.6%, water to 100%.

[0065] The preparation method of this water suspension is as follows:

[0066] 1) Diquat, synergist (alkylphenol polyoxyethylene ether and fatty amine polyoxyethylene ether), wetting and dispersing agent (phenethylphenol phosphate triethanolamine salt and EO-PO block polyether) , antifreeze (propylene glycol), defoamer (organic silicon defoamer, half of the total amount) is added to the reaction kettle with quantitative water according to the formula ratio, and the stirring device is turned on to stir until the materials are evenly mixed;

[0067] 2) To the mixture in s...

Abstract

A herbicidal composition containing diquat and triclopyr and applications thereof are disclosed. The composition includes active herbicidal components which are the diquat and the triclopyr. The weight ratio of the diquat to the triclopyr is (20-1):(1-20). In the composition, after the diquat and the triclopyr are compounded, the composition is free of antagonism, synergistic effects are obvious, weeding effects are obviously improved, and the composition has characteristics of rapid production of desired effects and long duration time. Compared with a single agent, the herbicidal spectrum is broadened, control effects are improved, the herbicide using amount is reduced, the herbicide using cost is reduced, development of herbicide resistance of weeds is delayed, disadvantages in practical application processes of noncropland herbicides at present are overcome and using choices of noncropland herbicide varieties are increased.

Description

technical field [0001] The invention belongs to the field of herbicides, and in particular relates to a herbicidal composition containing diquat and triclopyr and its application, which is suitable for preventing weeds in non-cultivated land. Background technique [0002] The growth of weeds in non-cultivated land affects the appearance of the city, or becomes the intermediate host or overwintering place of certain pests and diseases, thus bringing certain harm to urban greening or agricultural production. Chemical herbicides on non-cultivated land in my country are weed control without involving the cultivation of stubble crops, and the application of pesticides is generally based on herbicides such as destructive and long-lasting herbicides. The herbicides used on non-cultivated land are mainly paraquat, glyphosate, glufosinate and diquat. [0003] In 2012, the Ministry of Agriculture, the Ministry of Industry and Information Technology, and the State Administration of Qu...
