Problems solved by technology

Such as: tribenuron-methyl, isoproturon, and thifensulfuron-methyl are used to weed thoroughly in wheat fields, but the weeding speed is slow
For example, although the herbicide tribenuron-methyl+metrazone has a fast weeding speed, it has a long residual period, and it cannot be used in fields where peanuts and vegetables are planted later, which is prone to phytotoxicity

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 B100kg, the auxiliary agent 40kg, and the filler 850kg to obtain 1000gk10% emulsifiable concentrate.

[0016] 2. Take 300kg of the original drug A, 30kg of the original drug B, 60kg of auxiliary agents, and 610kg of fillers to obtain 1000gk 30% wettable powder.

[0017] 3. Take 100kg of the original drug A, 150kg of the original drug B, 60kg of auxiliary agents, and 690kg of fillers to obtain 1000gk 25% 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 A500kg, the original drug B60kg, the wetting agent 30kg, the disintegrant 30kg, the dispersant and the adhesive 30kg, the release agent 10kg, the carrier 350kg, and get 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. Get 400kg of the original drug A, 50kg 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 composite herbicide for wheat field is prepared from thifensulfuron-methyl, another herbicide Zuocaotong, carrier, surfactant, disperser and / or agricultural auxiliary. Its advantages are quickly taking its effect and short residual period (one month).

Description

technical field [0001] The invention relates to a wheat field herbicide composition. Background technique [0002] Although there are many types of herbicides for wheat fields at present, these products all have their own drawbacks. Some control gramineous weeds, and some control broad-leaved weeds, which cannot take into account the purpose of controlling both weeds. There are also some herbicides whose compound products can control both grass weeds and broadleaf weeds. Such as: tribenuron-methyl, isoproturon, and thifensulfuron-methyl are used to weed thoroughly in wheat fields, but the weeding speed is slow. For example, although the herbicide tribenuron-methyl+metrazone has a fast weeding speed, it has a long residual period, and it cannot be used in fields where peanuts and vegetables are planted later, which is prone to phytotoxicity. Contents of the invention [0003] The problem to be solved by the present invention is to provide a [0004] In order to solve th...
