Description

Herbicidal composition containing triazinone herbicide and ALS inhibitor herbicide and use thereof

The present invention relates to a method of controlling the growth of harmful plants using a herbicidal composition comprising an ALS inhibitor herbicide and a triazinone herbicide.

Harmful plant growth can lead to a significant reduction in crop yields. Therefore, it is very important to achieve a bumper crop, to control the growth of harmful crops, and to continue to control harmful plants in farmland.

ALS inhibitor herbicides can be used to control the growth of harmful plants. For example, ALS inhibitor herbicides include sulfonylurea herbicides such as amidosulfuron, azimsulfuron, bensulfuron, chlorimuron, cyclopropyl ether Cyclosulfamuron, ethoxysulfuron, flazasulfuron, flucetosulfuron, flupyrsulfuron, foramsulfuron, chloropyrazole Halosulfuron, imazosulfuron, mesosulfuron, Metazosulfuron, methiopyrisulfuron, monosulfuron, nicosulfuron, orthosulfamuron, oxasulfuron, Primisulfuron, Propyrisulfuron, pyrazosulfuron, rimsulfuron, sulfometuron, sulfosulfuron, trifloxysulfuron, pyrazole Zuomihuanglong, chlorsulfuron, cinosulfuron, ethametsulfuron, iodosulfuron, iofensulfuron, metsulfuron- Methyl), prosulfuron, thifensulfuron, triasulfuron, tribenuron, triflusulfuron, tritosulfuron, Metasulfuron methyl, chlorimuron-ethyl, clopyrasulfuron, and sulfometuron-methyl.

The above herbicides, their production processes, herbicide compositions containing the above herbicides and herbicides thereof are known in the art and are in the ninth edition of the British Crop Protection Commission's 1991 Pesticide Manual (the Pesticide) Manual, 9th edition (1991), The British Crop Protection Council, London), Ag Chem New Product Review, Ag Chem Information Services, Indianapolis, Ind. and the like.

However, ALS inhibitor herbicides, such as sulfonylurea herbicides, may be phytotoxic to crops. Sunflower is one of the crops that is sensitive to ALS inhibitor herbicides, with apical developmental delay, discoloration and root rupture (Alonso-Prados et al., 2002). The phytotoxicity of herbicides can affect crop growth and even death. Therefore, there is a need for a composition that is free of phytotoxic or small amounts of phytotoxicity and that is highly effective in controlling the growth of harmful plants.

Surprisingly, it has now been found that the herbicidal compositions of the invention comprising triazinone herbicides and ALS inhibitor herbicides are capable of reducing the phytotoxicity of ALS inhibitor herbicides to crops such as forage crops, such as sugar cane, which is harmful to The efficacy of plant growth will not decrease.

The present invention therefore relates to a method for controlling the growth of harmful plants and reducing the phytotoxicity of ALS inhibitor herbicides. The method comprises applying to the crop or its location a composition comprising a triazinone herbicide and an ALS inhibitor herbicide.

"Phytotoxicity" as described in the context of the present invention relates to all herbicide effects that impede the normal development of the crop. The phytotoxicity of herbicides may inhibit crop growth and even cause crop death. Therefore, to maintain crop health, a herbicide that is free of phytotoxicity or a small amount of phytotoxicity is required.

Triazine ketone herbicides containing ALS inhibitor herbicides can be administered continuously or simultaneously in any order and combination. The triazinone herbicide can be applied alone with the ALS inhibitor herbicide (including tank mix, premix, fermentation broth spray or slurry), and other pesticides such as other fungicides, insecticides and Nematicide, or as a mixture of agents (packaged) Premix, concentrate, compound (or product), and other pesticides, such as other fungicides, insecticides and nematicides.
