Problems solved by technology

[0002] Chemical weed control is one of the main means of weed control in paddy fields, and the use of a single compound herbicide can easily lead to weed resistance
At the same time, when weeds occur in paddy fields, the grass phases are complex, and grasses, sedges, and broad-leaved weeds are mixed, and the use of a single compound herbicide will show some defects and defects. Limitations, can not completely solve the weeds in farmland

Embodiment 1

[0023] Embodiment 1: Composition Pesticide Formulation Technology.

[0024] 24% N-(butoxymethyl)-α-chloro-α',6'-diethylacetanilide 0.6% 3-trifluoromethyl-N-(5,8-dimethoxy-[ 1,2,4]Triazolo[1,5-c]pyrimidin-2-yl)benzenesulfonamide dispersible oil suspension: N-(butoxymethyl)-α-chloro-α',6'- Diethylacetanilide 24%, 3-trifluoromethyl-N-(5,8-dimethoxy-[1,2,4]triazolo[1,5-c]pyrimidin-2-yl ) benzenesulfonamide 0.6%, quinine 6%, sodium lignosulfonate 4%, clay 2%, NNO 2%, silicon magnesium silicate 2%, calcium dodecylsulfonate 4%, organic silicon 3% , peanut oil 3%, methyl oleate to 100%. Put the above materials into the reactor mixer together, stir for 2 hours, open the feed valve at the bottom of the kettle, inject the materials into the multi-stage sand mill for grinding, and the fineness of the ground materials is 98% after passing through 5-10um. Put it in a high shear emulsification kettle for 4 hours.

Embodiment 2

[0027] Example 2: Indoor toxicity assay.

[0028] Test method: use soil irrigation method (NY / T 1155.5-2006), in an area of ​​0.01m 2 Fill the pot with a certain amount of soil to 3 / 4 of the pot, and then water from the top of the pot to make the soil completely moist to saturated. Sow 15-20 seeds of the target weeds evenly on the surface of the pot soil, cover with 1 cm of fine soil, and place them in the greenhouse for cultivation. After 24 hours, each pot was irrigated with 10ml of medicinal solution quantitatively, and each treatment was repeated 4 times, and the treatment without chemical was set as the control. After the treatment, the test materials were placed in the greenhouse for cultivation, and the growth of the target weeds was regularly observed. Always keep a 1-2cm water layer in the treatment pot. After 20 days, the damage symptoms and growth inhibition of the target were visually observed, and the fresh weight of the above-ground part was weighed, and the vi...

Embodiment 3

[0049] Example 3: The composition controls weeds in paddy fields.

[0050] Experimental crops: transplanted into paddy fields, 5 days after transplanting.

[0051] Application method: mix 300 kg of fine soil per hectare and spread, keep 3-5cm water layer for 5-10 days after application.

Abstract

The invention relates to a synergistic weeding composition for a paddy field. The synergistic weeding composition comprises a compound (A) and a compound (B) in a weight ratio of (10-80): 1, wherein (A) is N-(butoxymethyl)-alpha-chloro-alpha',6'-diethylacetanilide, and (B) is one selected from a group consisting of 3-chloro-2-metyl-N-(5,8-dimethoxy-[1,2,4]triazolo[1,5-c]pyrimidin-2-yl)benzsulfamide and 3-trifluoromethyl-N-(5,8-dimethoxy-[1,2,4]triazolo[1,5-c]pyrimidin-2-yl)pyridinesulfonamide. The synergistic weeding composition provided by the invention exerts synergistic effect on grassy weeds, improves weeding effect and is safe to paddy rice. The weeding composition has synergistic effect and a broadened weeding spectrum and is applicable to prevention and treatment of weeds in the paddy field.

Description

technical field [0001] The invention relates to a compound pesticide combination and its application technology, in particular to a paddy field synergistic herbicide composition. Background technique [0002] Chemical weed control is one of the main means of weed control in paddy fields, and the use of a single compound herbicide can easily lead to weed resistance. At the same time, when weeds occur in paddy fields, the grass phases are complex, and grasses, sedges, and broad-leaved weeds are mixed, and the use of a single compound herbicide will show some defects and defects. Limitations, can not completely solve the weeds in farmland. [0003] N-(butoxymethyl)-α-chloro-α',6'-diethylacetanilide belongs to amide herbicide compounds, mainly absorbed through weed shoots and young secondary roots, inhibiting protein synthesis in vivo, The young weed plants are swollen, deformed, dark green in color, and eventually lead to death. [0004] 3-Chloro-2-methyl-N-(5,8-dimethoxy-[1...
