Embodiment 1

[0020] Weigh 5% penoxsulam, 5% bensulfuron-methyl, 3% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, U.S.), 2% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate) ), 3% pull open powder BX (sodium dibutyl naphthalene sulfonate), 2% K-12 (sodium lauryl sulfate), 3% white carbon black, 5% ammonium sulfate, diatomaceous earth added to 100% parts by weight. 10% penoxsulam·bensulfuron-methyl water-dispersible granules are prepared by the above-mentioned raw materials through the conventional method for preparing water-dispersible granules, ie, mixing, ultrafine airflow pulverization, mixing, and granulation.

[0021] In this embodiment, the weight ratio of penoxsulam and bensulfuron-methyl can be changed between 1.6:1-1:40, and the total weight content of the two is still 10%, forming a new embodiment.

Embodiment 2

[0023] Weigh 1.5% penoxsulam, 60% bensulfuron-methyl, 5% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, U.S.), 3% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate ), 4% pull open powder BX (sodium dibutyl naphthalene sulfonate), 4% K-12 (sodium lauryl sulfate), 3% white carbon black, 5% ammonium sulfate, diatomaceous earth added to 100% parts by weight. 61.5% penoxsulam·bensulfuron-methyl water-dispersible granules were prepared by the above-mentioned raw materials through the conventional method for preparing water-dispersible granules, ie mixing, ultra-micro airflow pulverization, mixing and granulation.

[0024]In this embodiment, the weight ratio of penoxsulam and bensulfuron-methyl can be changed between 1.6:1-1:40, and the total weight composition of the two is still 61.5%, forming a new embodiment.

Embodiment 3

[0026] Weigh 16% penoxsulam, 10% bensulfuron-methyl, 5% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, U.S.), 2% diffusing agent NNO (alkylnaphthalenesulfonate formaldehyde condensate) ), 2% pull open powder BX (sodium dibutyl naphthalene sulfonate), 2% K-12 (sodium lauryl sulfate), 3% white carbon black, 5% ammonium sulfate, diatomaceous earth added to 100% parts by weight. 26% penoxsulam·bensulfuron-methyl water-dispersible granules are prepared by the above-mentioned raw materials through the conventional method for preparing water-dispersible granules, ie, mixing, ultrafine airflow pulverization, mixing, and granulation.

[0027] In this embodiment, the weight ratio of penoxsulam and bensulfuron-methyl can be changed between 1.6:1-1:40, and the total weight content of the two is still 26%, forming a new embodiment.

Abstract

The invention relates to a herbicide composition for preventing and removing weeds in farmlands and an application, in particular to a herbicide used for preventing and removing gramineous weeds, broadleaf weeds and sedge weeds in paddy fields. The herbicide composition is a binary herbicide mixed agent taking penoxsulam and bensulfuron methyl as active components. The weight ratio of the penoxsulam to the bensulfuron methyl in the composition is 1.6:1-1:40, preferably 1.6:1-1:10. The compound herbicide can be prepared into water dispersed granules, a suspending agent, an oil suspending agentand wettable powder. The invention is used for preventing and removing the weeds in the paddy fields, has reasonable components and better preventing effect in comparison with the activity of the components when being applied independently, expands the preventing and removing spectra of the weeds, lowers the preventing and removing cost, delays the generation of the resistibility of the weeds, has good safety to crops and conforms to the safety requirement of pesticide preparations. The invention has the fresh-weight average preventing and treating effect of 87.35-98.01% to the gramineous weeds, the broadleaf weeds and the sedge weeds in the paddy fields after being applied for thirty days.

Description

technical field [0001] The present invention relates to a paddy field herbicide composition, in particular to a kind of herbicide for preventing and treating gramineous weeds, broad-leaved weeds and sedge weeds in paddy fields, which is composed of penoxsulam, Bensulfuron-methyl is a binary herbicide composition with an active component. Background technique [0002] Since around 1950 when 2,4-D and 2M4Cl were widely used to control broad-leaved weeds in rice fields, the varieties of herbicides used in rice fields have developed rapidly, and the varieties have been continuously improved and perfected. Diphenyl ethers, sulfur Substitute carbamates, amides, quinoline carboxylic acids, sulfonylureas and other herbicides have formed a relatively complete chemical herbicide system suitable for different cultivation methods of rice, which has become indispensable and very important in the world's rice production. measures to increase production. [0003] However, with the contin...
