These two herbicides are used alone to control broad-leaved weeds, either they are quick-acting but not thorough, or weeding is thorough but slow, which is very harmful to wheat
However, the control effect on the vicious weeds of wheat fields, pig's weeds and varnish is not good.
Moreover, with the increase in the amount of herbicides used in wheat fields, the resistance of weeds is becoming more and more serious, and the harm of vicious weeds such as pig worms and lacquer is also more serious.

[0019] 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.
[0020] 1. Take 10kg of the original drug A, 300kg of the original drug B, 40kg of auxiliary agents, and 550kg of fillers to obtain 1000kg of 30% wettable powder.
[0021] 2. Take 30kg of the original drug A, 70kg of the original drug B, 60kg of auxiliary agents, and 840kg of fillers to obtain 1000kg of 10% wettable powder.
[0022] 3. Take 30kg of the original drug A, 150kg of the original drug B, 60kg of auxiliary agents, and 760kg of fillers to obtain 1000kg of 30% wettable powder.
[0024] The active ingredient is 10-85%, surfactant 0.1-10%, disintegrant 0.1-20%, dispersant and binder 5-30%, release agent 0.1-5%, carrier 1-40%, by formulating The premise is formed by granulation. Disintegration, dispersion, wetting and other performance symbols feel standard.
[0025] 4. Get the original drug A50kg, the original drug B500kg, the wetting agent 30kg, the disintegrant 30kg, the decomposition agent and the adhesive 30kg, the release agent 10kg, and the carrier 350kg to obtain 1000kg55% WDG.
[0027] The active ingredient is 10-85%, the wetting agent is 0.1-10%, the disintegrant is 0.1-20%, the dispersant and binder are 5-30%, and the particle size, suspending agent, dispersing agent, stabilizer and other properties meet the national standard .
[0028] 5. Get 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 decomposition agent and the binder, and 460kg of the carrier to obtain 1000kg of 45% DF.

Abstract
The invention discloses a composite weedicide. The composite weedicide comprises a mixture of 95 percent fluroxypyr and 97.4 percent carfentrazone serving as effective ingredients; and the range of the weight ratio of the 95 percent fluroxypyr to the 97.4 percent carfentrazone is between 1:99 and 99:1. The invention also discloses a plurality of preparation formulations of the composite weedicide. In the invention, the 95 percent fluroxypyr and the 97.4 percent carfentrazone are compounded and mixed to serve as a wettable powder preparation, which can give play to the comprehensive advantages of the two medicaments. The composite weedicide can not only achieve the effect of weeding rapidly and radically, but also reduce the dosage and facilitate the use of a peasant. The harm of various broad leaf weeds in a paddy field, a wheat field and a corn field can be prevented by using the weedicide once; therefore, the dosage of the weedicide in the paddy field, the wheat field, the corn field and the like can be reduced; and the prevention and removal effects on noxious weeds can be improved.
Description
technical field [0001] The invention relates to the technical field of pesticides, in particular, the invention relates to a herbicide; more specifically, the invention is a combined herbicide. Background technique [0002] Wheat fields, rice fields, and corn fields are large food crops in my country, but the development of combined herbicides is very slow. The used mefentrazone is an azole herbicide, and mefentrazone inhibits protoporphyrin oxidase, thereby causing membrane splitting. 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. It is safe for cereal crops such as wheat and corn. It has special effects on the weeds resistant to the long-term use of sulfonylurea herbicides, and is safe for subsequent crops. Fluroxypyr is a systemic conduction postemergence herbicide. After the drug is quickly absorbed by the plants, the sensitive plants will respond to typical hormoneherb...
