Embodiment 1

[0029] Example 1 (10% bispyribac-triclopyr oil suspension concentrate)

[0030]

[0031] Add the above materials (except organic bentonite) into the reactor mixer together, stir for 2 hours, then put them together with the pre-dissolved organic bentonite into a high-shear emulsification kettle for 2-3 hours, and open the bottom of the kettle after emulsification The feed valve is used to inject the material into the multi-stage sand mill for grinding, and the fineness of the ground material is 98% after passing through a 1-5um filter sieve, and then the material is discharged to produce 10% bispyribac-triclopyr with good fluidity Oxyacetic acid oil suspension.

[0032] With reference to "GB / T17980.40-2000 Criteria for Field Efficacy Tests of Pesticides (1) Herbicides Control Rice Field Weeds", the preparation prepared in Example 1 is used to prevent and treat annual weeds in direct-seeded rice fields, and is effective against gramineous weeds. , Cyperaceae weeds and broad-...

Embodiment 2

[0046] Example 2 (30% bispyribac-triclopyr water-dispersible granules):

[0047]

[0048] Add the above-mentioned weighed materials into the conical mixer and mix them evenly, and then pulverize them through the jet mill. The crushed materials are then mixed through the conical mixer. The fineness of the mixed materials is 98% and passes through a 600-mesh standard sieve Add it into a kneader to knead into a plastic material, and finally put this material into an extrusion granulator to extrude and granulate, and after granulation, dry and sieve to obtain 30% bispyribac-chlorpyroxyacetic acid water dispersion granules.

[0049] With reference to "GB / T17980.40-2000 Criteria for Field Efficacy Tests of Pesticides (1) Herbicides Control Rice Field Weeds", the preparation prepared in Example 2 was used to control annual weeds in paddy seedling throwing fields, and was effective against Gramineae weeds. The control effects of grasses, sedge weeds and broad-leaved weeds were cou...

Embodiment 3

[0062] Example 3 (45% bispyribac-triclopyr wettable powder)

[0063]

[0064] Add the above-mentioned weighed materials into the conical mixer and mix them evenly, and then pulverize them through the jet mill. The crushed materials are then mixed through the conical mixer. The fineness of the mixed materials is 98% and passes through a 600-mesh standard sieve That is, 45% bispyribac-triclopyr wettable powder was obtained.

[0065] With reference to "GB / T17980.40-2000 Criteria for Field Efficacy Tests of Pesticides (1) Herbicides Control Paddy Field Weeds", the preparation prepared in Example 3 is used to prevent and treat annual weeds in rice seedling throwing fields, and to Gramineae The control effect of weeds, Cyperaceae weeds and broad-leaved weeds was counted. The experiment was carried out after the 4th leaf stage of rice. The experimental field was sandy loam, the ditches were unobstructed, and the water and drainage were convenient. The grass phase in the field was ...

Abstract

The invention discloses a weed control composition containing bispyribac-sodium and triclopyr, and belongs to the technical field of pesticide weed control. The weed control composition containing bispyribac-sodium and triclopyr comprises an effective amount of an active ingredient I and active ingredient II, wherein the rest is an auxiliary ingredient in a pesticide preparation, wherein the active ingredient I is bispyribac-sodium, the active ingredient II is triclopyr, and the weight part ratio of the active ingredient I to the active ingredient II is 20: 1 to 1: 20, preferably 10: 1 to 1: 10. The composition provided by the invention has an obvious synergistic effect and is suitable for annual weeds in paddy fields.

Description

technical field [0001] The invention belongs to the technical field of pesticide weeding, and relates to a herbicidal composition with bispyribac and triclopyr as active ingredients, which is suitable for controlling annual weeds in paddy fields. Background technique [0002] Rice is one of the main food crops in my country, but various weeds in rice have seriously affected the yield of rice. In recent years, a labor-saving and water-saving planting method - direct-seeding rice has risen rapidly, making it particularly important to control weeds. Among them, resistant barnyardgrass and Qianjinzi, etc., have a greater impact on rice in rice fields and are more difficult to control. Gramineae weeds, followed by broad-leaved weeds such as bermudagrass, knotweed, and eye grass. [0003] At present, the development of herbicides in rice fields is relatively lagging behind, and there are not many varieties. They have been used for a long time, and the weeds have developed resist...
