Problems solved by technology
[0004] Compared with insecticides and fungicides, herbicides have higher requirements for the use of technology. Improper use of insecticides and fungicides may only affect the control effect, while improper use of herbicides is related to the safety of crop growth.
Most of the existing "annual weed herbicides" have a single m...

Embodiment 1
[0022] A herbicide for annual weeds in direct-seeding rice fields, which is a mixture of pyrazosulfuron-methyl, clomazone and butachlor. Pyrazosulfuron-methyl is a highly effective sulfonylurea selective paddy field herbicide Clomazone is an organic heterocyclic selective pre-emergence herbicide, and butachlor is a special herbicide with high selectivity for rice fields. It is safe for rice and has a wide herbicidal spectrum. The mixture of the three can be used for annual weeds in direct-seeded rice fields. It has better control effect.
[0023] Raw materials: by mass percentage, pyrazosulfuron-methyl technical 2%, clomazone technical 8%, butachlor technical 60%, castor oil polyoxyethylene ether condensate 20%, organic bentonite 2.5%, oleic acid Methyl ester 7.5%;
[0024] Such as figure 1 As shown, mix pyrazosulfuron-methyl original drug, castor oil polyoxyethylene ether condensate, organic bentonite and methyl oleate, grind together, pass through a 75 μm test sieve, and a...
Embodiment 2
[0026] Raw materials: by mass percentage, pyrazosulfuron-methyl technical 1.7%, clomazone technical 8.8%, butachlor technical 62.5%, castor oil polyoxyethylene ether condensate 20%, organic bentonite 2.5%, oil Acid methyl ester makes up 100%; Preparation processing flow is as embodiment 1.
Embodiment 3
[0028] Raw material preparation: by mass percentage, pyrazosulfuron-methyl technical 2.3%, clomazone technical 7.2%, butachlor technical 57.5%, castor oil polyoxyethylene ether condensate 20%, organobentonite 2.5%, oleic acid Methyl ester makes up 100%; the preparation process is as in Example 1.

Abstract
The invention discloses a herbicide for annual weeds in direct-seeding paddy fields. The herbicide includes pyrazosulfuron-methyl, clomazone and butachlor as technical drugs; wherein, butachlor, clomazone and pyrazosulfuron-methyl The herbicides are compounded according to the ratio of 30:4:1; after compounding, the original drugs of pyrazosulfuron-methyl, clomazone and butachlor account for 1-80% of the total mass of the herbicide. The herbicide processing method includes: grinding the pyrazosulfuron-methyl technical substance, emulsifier, thickener and solvent, passing through a 75 μm test sieve, and adding them to the mixing kettle; respectively adding the clomazone and butachlor technical substances to the mixing kettle , mix well at room temperature. The present invention is formed by mixing pyrazosulfuron-methyl, clomazone and butachlor. Pyrazosulfuron-methyl is a high-efficiency sulfonylurea selective paddy field herbicide, and clomazone is an organic heterocycle Selective pre-emergence herbicide, butachlor is a special herbicide with high selectivity for paddy fields. It is safe for rice and has a wide herbicidal spectrum. The mixture of the three has a good control effect on annual weeds in direct-seeded paddy fields.
Description
technical field [0001] The invention belongs to the technical field of pesticides and relates to a herbicide, in particular to a herbicide for annual weeds in direct-seeded rice fields and a processing method thereof. Background technique [0002] Herbicides refer to agents that can completely or selectively kill weeds, also known as herbicides, a class of substances used to eliminate or inhibit plant growth. Among them, sodium chlorate, borax, arsenate, and trichloroacetic acid have a deadly effect on any kind of plants, and their effects are affected by three factors: herbicides, plants, and environmental conditions. According to the function, it can be divided into killing and selective herbicides. Most of the selective herbicides, especially the derivatives of nitrophenol, chlorophenol and carbamic acid, are effective. [0003] The development of herbicides in the world is gradually stabilizing, mainly developing varieties with high efficiency, low toxicity, broad spect...
