Embodiment 1

[0026] Example 1 (20% cyprosulfuron-pyrimifluben oil suspension concentrate):

[0027] Cyprosulfuron-methyl 10%,

[0028] Pyrimifluben 10%,

[0029] Styrene phenol polyoxyethylene ether 5-6%,

[0030] Sodium lignosulfonate 7-8%,

[0031] Organic bentonite 5-9%,

[0032] Refined soybean oil to 100%.

[0033] Put the above materials (except organic bentonite) into the reaction kettle mixer together, stir for 2 hours, put the materials together with the pre-dissolved organic bentonite into the high-shear emulsification kettle, cut 2 materials and mix them with the pre-dissolved Put the organic bentonite into the high-shear emulsification kettle together. After 3 hours of emulsification, open the feed valve at the bottom of the kettle after emulsification, and inject the material into a multi-stage sand mill for grinding. The fineness of the ground material is 98% after passing through 1-5um. After discharging, it can be made into 20% cyprosulfuron-pyrimifluben oil suspensio...

Embodiment 2

[0038] Example 2 (20% Cyprosulfuron-pyrimifluben water-dispersible granules):

[0039] Cyprosulfuron-methyl 10%,

[0040] Pyrimifluben 10%,

[0041] Sodium lauryl sulfate 4~5%,

[0042] Carboxylate 5-6%,

[0043] Urea 30-40%,

[0044] Kaolin up to 100%.

[0045] Put the above materials together into the conical mixer and mix evenly, and then pulverize through the jet mill, and then mix the pulverized materials through the conical mixer. Knead into a plastic material, and finally put the material into an extrusion granulator to extrude and granulate. After granulation, dry and sieve to obtain 20% cyprosulfuron-pyriflun-methyl water-dispersible granules.

[0046] This example is used to control barnyardgrass, Cyperaceae weeds and annual broad-leaved weeds in paddy throwing seedling fields: the statistics of barnyardgrass, Cyperaceae weeds and annual broad-leaved weeds are carried out, and 4 treatments are set up in the experiment. 1 is 20% cyprosulfuron-pyriflun-methyl w...

Embodiment 3

[0050] Example 3 (25% Cyprosulfuron-pyrimifluor WP):

[0051] Cyprosulfuron-methyl 10%,

[0052] Pyriflubac 15%,

[0053] Sodium lauryl sulfate 2~5%,

[0054] Sodium butylnaphthalene sulfonate 3-5%,

[0055] Calcium lignosulfonate 5-7%,

[0056] White carbon black 5~8%,

[0057] Kaolin up to 100%.

[0058] Put the above materials together into the conical mixer and mix them evenly, and then crush them through the jet mill, and then mix the pulverized materials through the conical mixer. Cyprosulfuron-pyrimifluben wettable powder.

[0059] This example is used to control barnyardgrass, Cyperaceae weeds and annual broad-leaved weeds in rice throwing fields: statistics are made on Barnyardgrass, Cyperaceae weeds and annual broad-leaved weeds. There were 4 treatments in the experiment, treatment 1 was 25% cyprosulfuron-pyrimiflun-methyl WP, treatment 2 was a single dose of 10% cyprosulfuron-methyl wettable powder, treatment 3 was a single dose of 10% pyrimazone Ether wet...

Abstract

The invention relates to a weeding composition containing active components of cyclosulfamuron and pyriminobac-methyl in a weight ratio of 12:1-1:10. The weeding composition provided by the invention has the advantage that compound of cyclosulfamuron and pyriminobac-methyl improves weeding effect, expands weed control spectrum, reduces resistance risk caused by single usage of cyclosulfamuron or pyriminobac-methyl, realizes low toxicity and low residual, substantially reduces drugs dose, drug frequency and usage cost; and the weeding composition is suitable for controlling barnyard grass, nutgrass flatsedge weeds and annual broad leaf weeds in rice fields.

Description

technical field [0001] The invention belongs to the technical field of agricultural weeding, and in particular relates to a herbicidal composition with cyprosulfuron-methyl and pyriflubac-methyl as active ingredients, which is suitable for controlling barnyardgrass, Cyperaceae weeds and annual broad-leaved weeds in paddy fields. Background technique [0002] As people's requirements for food safety and environmental protection continue to increase, the use of pesticides on crops that people rely on for survival has also attracted much attention. With the phase-out of highly toxic pesticides, new agents with high efficiency, low toxicity, safety and environmental friendliness are needed. At the same time, the long-term use of pesticides has resulted in the resistance of pests and weeds, and the requirements for control agents are getting higher and higher. This requires pesticide research and development personnel to develop efficient and safe new agents to meet the control r...
