Problems solved by technology

However, with the continuous use of many herbicide varieties in large areas of rice fields, there will inevitably be some problems that need to be faced and should be solved seriously: mainly the outstanding resistance of weeds, among which barnyardgrass is effective against propanil and dichloroquine. acid, butachlor, and carbad are more resistant. Recently, common weeds such as Cyperaceae, Cyperaceae, Alismaceae and other common weeds The resistance to sulfonylurea herbicides has made the weeding problem more complicated; the damage of perennial weeds has become an important problem, especially the perennial weeds of Cyperaceae; the control p

Embodiment 1

[0028] Embodiment 1. preparation of granules (the sum of the raw material parts for preparing pesticides is 100 parts)

[0029] With 70 parts by weight of active ingredient mixture (32 parts by weight of penoxsulam+38 parts by weight of bensulfuron-methyl), 6 parts by weight of liquid paraffin, 4 parts by weight of polyvinyl alcohol, 3 parts by weight of stearic acid Calcium, the remaining amount of clay, mix the above materials to obtain 100 parts of powder mixture, add an appropriate amount of water, mix with a small kneader, then granulate, granulate with a granulator, dry, and sieve to obtain the preparation.

Embodiment 2

[0030] Embodiment 2. prepare suspending agent (the sum of the raw material parts of preparing pesticide is 100 parts)

[0031] 40 parts by weight of the active mixture (18 parts by weight of penoxsulam + 22 parts by weight of bensulfuron-methyl), 5 parts by weight of carboxymethylcellulose (as a thickener), 3 parts by weight of propylene glycol (as an antifreeze agent), 10 parts by weight of calcium lignosulfonate (as a wetting and dispersing agent), and the water of the remainder, the mixture is obtained through main processes such as mixing, stirring, and sand milling.

Embodiment 3

[0032] Embodiment 3. prepare water-dispersible granules (the sum of the raw material parts for preparing pesticides is 100 parts)

[0033] With 75 parts by weight of active ingredient mixture (32 parts by weight of penoxsulam+43 parts by weight of bensulfuron-methyl), 5 parts by weight of polyvinyl alcohol, 2 parts by weight of sodium lauryl sulfate, 6 parts by weight of lignosulfonic acid calcium and the balance of kaolin.

[0034] After the above ingredients were mixed and ground into a fine powder in a plug-type disc mill, the powder was granulated in a fluidized bed by spraying water as the granulating liquid.

Abstract

The invention discloses a weeding composition containing penoxsulam and bensulfuron-methyl, which comprises active ingredient a and active ingredient b, wherein the active ingredient a is penoxsulam, the active ingredient b is bensulfuron-methyl, the weight ratio of the a to the b is 1-90:90-1; preferably, the weight ratio of the a to the b is 1-50:50-1, and particularly preferred, the weight ratio of the a to the b is 1-10:10-1. The active ingredients of the composition account for 8 to 95 percent of the total weight of the composition, and the balance is agriculturally acceptable pesticide adjuvant.

Description

technical field [0001] The invention belongs to the field of agricultural plant protection, and relates to a herbicidal composition with improved performance, especially a herbicidal composition containing penoxsulam and bensulfuron-methyl. Background technique [0002] In recent years, the variety of herbicides used in rice fields has developed rapidly, and the varieties have been continuously improved and perfected. Herbicides such as diphenyl ethers, thiocarbamates, amides, quinoline carboxylic acids, and sulfonylureas have emerged successively, forming A relatively complete chemical herbicide system adapted to different rice cultivation methods has become an indispensable and very important yield-increasing measure in the world's rice production. However, with the continuous use of many herbicide varieties in large areas of rice fields, there will inevitably be some problems that need to be faced and should be solved seriously: mainly the outstanding resistance of weeds,...
