Problems solved by technology

[0004] Mesotrione is easy to conduct in the xylem and phloem of plants, and has contact killing effect and specific effect. The field efficacy test results show that 100 g / L mesotrione suspension concentrate is effective against annual broad-leaved weeds and some grass weeds in corn fields. Grasses such as velvetleum, amaranth, quinoa, Polygonum, barnyardgrass, crabgrass, etc. have good control effects, but have poor control effects on amaranth and some grass weeds

Embodiment 1

[0021] The water-dispersible granules containing mesotrione and clopyralid of the present embodiment are made of the following components by weight percentage:

[0022] Mesotrione 20%

[0023] Clopyralid 30%

[0024] Surfactant 11%

[0025] Filling balance

[0026] In this example, the weight content of the active ingredients mesotrione and clopyralid in the water-dispersible granules is 50%. Surfactants are wetting and dispersing agents. The wetting agent is sodium lauryl sulfate, with a weight content of 2%; the dispersant is calcium lignosulfonate, with a weight content of 9%; the filler is white carbon black and kaolin, and the weight content of white carbon black is 10%.

[0027] The production method of the water-dispersible granules containing mesotrione and clopyralid in this embodiment is to add the active ingredients mesotrione and clopyralid into the carrier, then add a surfactant, and mix in a mixer , add 17% water after pulverized by airflow machine, then kne...

Embodiment 2

[0029] The difference between this embodiment and embodiment 1 is: the water dispersible granule of this implementation is made of the following components by weight percentage:

[0030] Mesotrione 25%

[0031] Clopyralid 50%

[0032] Surfactant 12%

[0033] Filling balance

[0034] In this example, the weight content of the active ingredients mesotrione and clopyralid in the water-dispersible granules is 70%. Surfactants are wetting and dispersing agents. The wetting agent is sodium lauryl sulfate, with a weight content of 3%; the dispersant is an alkylnaphthalene sulfonate formaldehyde condensate, and the weight content is 9%; the filler is attapulgite.

Embodiment 3

[0036] The difference between this embodiment and embodiment 1 is: the water dispersible granule of this implementation is made of the following components by weight percentage:

[0037] Mesotrione 12.5%

[0038] Clopyralid 12.5%

[0039] Surfactant 10%

[0040] Filling balance

[0041] In this example, the weight content of the active ingredients mesotrione and clopyralid in the water-dispersible granules is 25%. Surfactants are wetting and dispersing agents. The wetting agent is sodium lauryl sulfate, with a weight content of 3%; the dispersant is an alkylnaphthalene sulfonate formaldehyde condensate, and the weight content is 7%; the filler is attapulgite.

Abstract

The invention relates to a water dispersible granule containing mesotrione and clopyralid and a production method thereof. The water dispersible granule contains mesotrione and clopyralid as active ingredients and accounts for 1%-90% of a herbicide by weight percent, wherein the weight ratio of the mesotrione to the clopyralid is 1: (0.1-10), preferably 1: (1-2). According to the invention, the synergistic effect of the prepared herbicide is significant, and the pesticide effect is greatly improved; the pesticide effect is improved, so that the field dosage of the active ingredients is reduced, the production and use costs are reduced, and the pesticide residue and the environmental pollution are reduced; and the water dispersible granule is composed of the active ingredients with different action mechanisms, so that action sites are increased, thereby being beneficial to overcoming and delaying the drug resistance of weeds.

Description

technical field [0001] The invention belongs to the field of agricultural herbicides, in particular to a water-dispersible granule containing mesotrione and clopyralid and a production method thereof. Background technique [0002] The application of chemical herbicides is the most effective means of controlling weeds in farmland. However, long-term continuous high-dose use of a single chemical herbicide is likely to cause problems such as herbicide residues, environmental pollution, and the development of weed resistance and resistance. The development of new varieties and reasonable mixing are effective ways to solve the above problems. However, as the price of new herbicide varieties continues to rise, the development of compound agents with less investment and short development cycles is more and more popular among domestic and foreign researchers. Pay attention to. [0003] Mesotrione, a triketone compound, is a preemergence and postemergence broad-spectrum selectiv...
