Embodiment 1
[0075] Weigh 40% etesulfuron-methyl, 40% penoxsulam, 3% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, USA), 2% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate) , 1% pull open powder BX (sodium dibutyl naphthalene sulfonate), 1% K-12 (sodium lauryl sulfate), 3% soluble starch, 3% glucose, and kaolin are added to 100% by weight. The above-mentioned raw materials are prepared through the conventional method for preparing water-dispersible granules, ie, mixing, ultrafine airflow pulverization, mixing, and granulation to prepare 80% ethersulfuron-pentoxsulam water-dispersible granules.
Embodiment 2
[0077] Weigh 2% etesulfuron-methyl, 64% penoxsulam, 3% TERSPERSE 2700, 4% sodium lignosulfonate, 1% pull-off powder BX, 1% K-12, 1% carboxymethylcellulose, Add 3% urea and diatomaceous earth to 100% by weight. The above-mentioned raw materials are prepared through the conventional method for preparing water-dispersible granules, ie, mixing, ultrafine airflow pulverization, mixing, and granulating steps to prepare 66% etesulfuron-pentoxsulam water-dispersible granules.
Embodiment 3
[0079] Weigh 32% etesulfuron-methyl, 1% penoxsulam, 4% TERSPERSE 2700, 1% pull open powder BX, 1% K-12, 0.8% dextrin, 5% ammonium sulfate, attapulgite to 100 % parts by weight. The above-mentioned raw materials are prepared through the conventional method for preparing water-dispersible granules, ie, mixing, ultrafine airflow pulverization, mixing, and granulation to prepare 33% etesulfuron-pentoxsulam water-dispersible granules.

Abstract
The invention discloses a herbicide for preventing and removing grassy weeds, broadleaf weeds and cyperaceae weeds in rice paddy fields, which is a binary herbicide mixture taking cinosulfuron and penoxsulam as active ingredients, and the weight ration of the cinosulfuron to the penoxsulam in the composition is (32:1)-(1:32), while (8:1)-(1:8) is preferential. The compound herbicide can be prepared into water dispersible granules, wettable powder, powder, granules, suspension and dispersible oil suspension. The herbicide can be used for preventing and removing the weeds in the rice paddy fields and has reasonable components, and the prevention effect is better than the activity when independently applying each component, thereby expanding the weed preventing and removing spectrum, reducing the preventing and removing cost, retarding the production of weed resistance, having good safety for crops and being in line with the requirements on the safety of pesticide preparations.
Description
technical field [0001] The present invention relates to a herbicide composition containing etesulfuron-methyl and penoxsulam, in particular to a herbicide used for preventing and treating gramineous weeds, broad-leaved weeds and sedge weeds in paddy fields. It is a binary herbicide composition composed of ethersulfuron-methyl and penoxsulam as active components. 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.
