Embodiment 1

[0085]Weigh 3% mefentrazone, 7% tribenuron-methyl, 30% fluroxypyr, 3% TERSPERSE 2700, 2% diffusing agent NNO, 3% pull-off powder BX (sodium dibutylnaphthalene sulfonate), 2 % K-12 (sodium lauryl sulfate), 5% soluble starch, 5% 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 granulating steps to prepare 40% of the mefentrazone-tribesulfuron-pyroxyfen water-dispersible granules.

Embodiment 2

[0087] Weigh 1.6% mefentrazone, 10.4% tribenuron-methyl, 48% fluroxypyr, 4% TERSPERSE2700, 2% diffusing agent NNO, 1% pull-off powder BX, 1% K-12, 1% carboxymethyl Cellulose, 3% urea, and diatomaceous earth are added to 100% by weight. The above-mentioned raw materials are prepared through the conventional method for preparing water-dispersible granules, ie, mixing, ultra-micro airflow pulverization, mixing, and granulating steps to prepare 60% mefentrazone·tribesulfuron·fluroxyrpyr water-dispersible granules.

Embodiment 3

[0089] Weigh 10% carfentrazone, 2.5% tribenuron-methyl, 40% fluroxyfen, 4% TERSPERSE 2700, 1% pull-off powder BX, 1% K-12, 0.5% dextrin starch, 2% ammonium sulfate , Attapulgite added to 100% by weight. The above-mentioned raw materials are prepared through the conventional method for preparing water-dispersible granules, ie, mixing, ultra-micro airflow pulverization, mixing, and granulating steps to prepare 52.5% of mefentrazone-tribesulfuron-chlorfluroxyacetic acid water-dispersible granules.

Abstract

The invention discloses a herbicide composition for preventing and killing off farmland weeds and application thereof, and in particular relates to a herbicide for preventing and controlling broadleaf weeds in the wheatfield. The herbicide composition is a triplet herbicide mixture consisting of carfentrazone-ethyl serving as a first active ingredient, tribenuron-methyl or thifensulfuron-methyl serving as a second active ingredient and fluroxypyr serving as a third active ingredient. The weight ratio of the first active ingredient to the second active ingredient to the third active ingredient in the composition is (1-16) to (2-32) to (8-128), and preferably (1-10) to (2-10) to (10-30); and the composition can be prepared into agriculturally allowable formulations such as wettable powder, water dispersible granules and dispersible oil suspending agents in practical application. The composition has the advantages of expanding the weed prevention and control spectrum, reducing the herbicide application frequency, reducing the prevention and control cost, slowing down the production of herbicide resistance of the weeds and meeting the requirement on safety of pesticide formulations, along with reasonable components, good weed control effect and high crop safety.

Description

technical field [0001] The present invention relates to a herbicide composition for wheat fields, in particular to a herbicide composition for controlling broad-leaved weeds in wheat fields, which consists of the first active ingredient mefentrazone, the second active ingredient tribenuron-methyl or thiensulfone Long, and the third active ingredient fluroxypyr. Background technique [0002] Fentrazone English common name carfentrazone-ethyl, molecular formula C 15 h 14 Cl 2 f 3 N 3 o 3 , chemical name ethyl-2-chloro-3-{2-chloro-5-[4-(difluoromethyl)-4,5-dihydro-3-methyl-5-oxo-1H-1,2 , 4-triazol-1-yl]-4-fluorophenyl}propionic acid ethyl ester. Mefentrazone inhibits protoporphyrin oxidase, thereby splitting the membrane. It is used on cereal crops for post-emergence foliar treatment, so that sensitive broad-leaved weeds will be blocked and quickly dry up and die. The weed killing speed is fast, and it can be absorbed by the leaves of the plants within 15 minutes after ...
