Problems solved by technology

At present, the production and application of chemical herbicides have been greatly improved, but because most of the herbicides used in potatoes are not very selective, they can only be selected by changing the method of use.

Embodiment 1

[0010] Embodiment 1. The weight proportion and preparation method of each component of 25% rimsulfuron-clethodim oil suspension concentrate:

[0011] Trisulfuron-methyl: 15%

[0012] Clethodim: 10%

[0013] Silica: 2%

[0014] Pull open powder BX: 1%

[0015] Farm milk 0408: 10%

[0016] Methyl oleate: 62%

[0017] After the above components are mixed, wet pulverization is used to make the average particle size below 5 μm to obtain an oil suspension.

Embodiment 2

[0018] Embodiment 2. The weight ratio and preparation method of each component of 45% rimsulfuron-ethyl quine wettable powder:

[0019] Trisulfuron-methyl: 30%

[0020] Arginine: 15%

[0021] Methylcellulose: 6%

[0022] Sodium Lauryl Sulfate: 4%

[0023] Kaolin: 45%

[0024] Put all the materials into the reaction kettle at one time, make them fully mixed under stirring conditions, crush and pour to a certain fineness.

Embodiment 3

[0025] Example 3. The weight ratio and preparation method of the components of 24% rimsulfuron-methyloxypyridine oil suspension concentrate:

[0026] Trisulfuron-methyl: 16%

[0027] High-efficacy haloxyfop: 8%

[0028] Silica: 4%

[0029] Farm milk 0408: 10%

[0030] Methyl oleate: 62%

[0031] After the above components are mixed, wet pulverization is used to make the average particle size below 5 μm to obtain an oil suspension.

Abstract

The invention discloses a weeding composition for potato fields, the active component of which is formed by combination of rimsulfuron with clethodim or sethoxydim herbicide by weight ratio of 1:4-4:1. The composition can be prepared into oil suspension agent, emulsifiable concentrate, wettable powder, water dispersible granules and the like in accordance with the known methods. The composition is characterized by high-efficient weeding effect, wide weeding spectral, less dosage, low residue, low cost, safety to the crops, and better control effect to the broadleaf weeds and grassy weeds, and can basically control the hazards of full season weeds in the potato fields by pesticide application once.

Description

Technical field: [0001] The invention relates to a herbicidal composition for post-emergence potato field, which belongs to the technical field of pesticides. technical background: [0002] Potato is one of the main economic crops in our country, and weeds in potato seriously affect the quality and yield of potato. Weeds are plants cultivated unconsciously by people. They compete with crops for fertilizer, water, sunlight, and land. If they are not controlled, the quality and yield of agricultural products will decline and become a major disaster in agricultural production. At present, the production and application of chemical herbicides have been greatly improved, but since most of the herbicides used in potatoes are not very selective, they can only be selected by changing the method of use. [0003] After in-depth research and experiments, the inventor found that rimsulfuron-methyl was used in combination with acetaminophen, high-efficiency haloxyfop, clethodim, Jingwen...
