Embodiment 1

[0013] Embodiment 1 wettable powder (WP)

[0014] The active ingredient is 1-80%, the surface active agent is 1-20%, and the rest is filler, which is obtained by mixing and pulverizing. The fineness meets the requirements of spraying, generally 325 mesh.

[0015] 1. Get the original drug A10kg, the original drug B300kg, the auxiliary agent 40kg, and the filler 550kg to obtain 1000gk30% emulsifiable concentrate.

[0016] 2. Take 30kg of the original drug A, 70kg of the original drug B, 60kg of auxiliary agents, and 840kg of fillers to obtain 1000gk10% wettable powder.

[0017] 3. Take 30kg of the original drug A, 150kg of the original drug B, 60kg of auxiliary agents, and 760kg of fillers to obtain 1000gk30% wettable powder.

Embodiment 2

[0018] Embodiment 2 water dispersible granules (WDG)

[0019] 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 performance symbols feel standard.

[0020] 4. Get the original drug A50kg, the original drug B500kg, the wetting agent 30kg, the disintegrant 30kg, the dispersant and the adhesive 30kg, the release agent 10kg, and the carrier 350kg to obtain 1000kg55% WDG.

Embodiment 3

[0021] Example 3 Dry Suspension Concentrate (DF).

[0022] 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, suspending agent, dispersing agent, stabilizer and other properties meet the requirements of national standards.

[0023] 5. Take 50kg of the original drug A, 400kg of the original drug B, 30kg of the wetting agent, 30kg of the disintegrating agent, 30kg of the dispersant and the binder, and 460kg of the carrier to obtain 1000kg of 45% DF.

Abstract

A herbicide for wheat field is prepared from thifensulfuron-methyl, fluroxypyr, carrier, surfactant, disperser and / or agricultural auxiliary. Its advantages are high effect and short residual period (one month).

Description

technical field [0001] The invention relates to a wheat field herbicide. Background technique [0002] With the rapid development of society, science and technology have been further improved. Farmers' continuous awareness and use of herbicides. At present, the types of herbicides in wheat fields are also changing, and the secondary weeds in wheat fields have evolved into major weeds. Such as Zeqi (mao Maoyan) and pig's weeds are already the main weeds in wheat fields, and they are difficult to control. At the same time, with the increase of dosage, the resistance of weeds is continuously strengthened. Although the existing tribenuron-methyl + fluroxypyr has special effects on lacquer and pig worm, it also has its own limitations. The first is that the medication period is short and the medication is applied from the 2-leaf stage to before jointing of wheat. Secondly, it is not safe for some subsequent crops. For example, the safe interval for planting peanuts is at lea...
