Embodiment 1

[0010] Embodiment 1, wettable powder (WP)

[0011] The active ingredient is 1-80%, the surfactant is 1-20%, and the rest is filler, which is obtained through mixing and crushing. The fineness meets the requirements of spraying, generally 325 mesh. Active ingredient A:B=20-1:1 (mass percentage, the same below).

[0012] 1. Take 90kg of original drug A, 10kg of original drug B, 40kg of auxiliary agent, and 860kg of filler to obtain 1000kg of 10% WP.

[0013] 2. Take 170kg of the original drug A, 30kg of the original drug B, 60kg of auxiliary agents, and 740kg of fillers to obtain 1000kg of 20% WP.

[0014] 3. Take 260kg of the original drug A, 40kg of the original drug B, 80kg of auxiliary agents, and 620kg of fillers to obtain 1000kg of 30% WP.

Embodiment 2

[0015] Embodiment 2, water dispersible granule (WDG)

[0016] Active ingredient 10-85%, wetting agent 0.1-10%, disintegrant 0.1-20%, dispersant and binder 5-30%, release agent 0.1-5%, carrier 1-40%, formulated into The premise is formed by granulation. Disintegration, dispersion, wetting and other properties meet the requirements of national standards. Active ingredient A:B=100-2:1 (mass percentage, the same below).

[0017] 4. Take 500kg of original drug A, 50kg of original drug B, 30kg of wetting agent, 30kg of disintegrating agent, 30kg of dispersant and adhesive, 10kg of release agent, and 350kg of carrier to obtain 1000kg of 55% WDG.

Embodiment 3

[0018] Embodiment 3, dry suspension (DF)

[0019] 10-85% of active ingredient, 0.1-10% of wetting agent, 0.1-20% of disintegrating agent, 5-30% of dispersant and binder. Particle size, suspension rate, dispersibility, stability and other properties meet the requirements of national standards. Active ingredient A:B=100-2:1 (mass percentage, the same below).

[0020] 5. Take 400kg of the original drug A, 50kg of the original drug B, 30kg of the wetting agent, 30kg of the disintegrant, 30kg of the dispersant and the binder, and 450kg of the carrier to obtain 1000kg of 45% DF.

Abstract

The invention discloses a wheat-field weedicide composition, exactly a dual mixed preparation. In the composition, the quality percent of chlorofluoro pyraoxyacetic acid 1-methyl heptyl ester) is 1%-80%, and that of tribenuron is 0.1%-50%. It has advantages of safety to crops, enlarged weeding spectrum, reduced dosage, convenient use and so on. It can more effectively prevent malignant weeds such as Galium aparine L and Zexi, and also effectively control the harm of alternanthera philoxeroides, able to be prepared into wettable powder, water granule, milk oil, dry suspension and so on.

Description

(1) Technical field [0001] The invention belongs to pesticide herbicides, and is precisely a compound compound of fluroxypyr 1-methylheptyl (fluroxypyr ester) and sulfonylurea herbicide tribenuron-methyl for controlling broad-leaved weeds in wheat fields herbicide composition. (2) Background technology [0002] The perennial planting area of ​​wheat in my country is about 27.5 million hectares, which is the second largest planting crop after rice. The damage rate of weeds in wheat fields is greater than 75%, and the resulting reduction in yield is about 15%, up to more than 80%, which is an important factor affecting the quality and yield of wheat. Fluoroxypyroxyacetic acid 1-methylheptyl ester (English common name: fluroxypyr meptyl; chemical name: 4-amino-3,5-dichloro-6-fluoro-2-pyridineoxyacetic acid 1-methyl-heptyl Ester) is the active ingredient of the broadleaf herbicide "Shitalong" (product of Dow AgroSciences, USA) commonly used in wheat fields. It is a selective ...
