Embodiment 1

[0026] Example 1 (8% Penoxsulam · Pyriflubac oil suspension concentrate):

[0027] Penoxsulam 2%,

[0028] Pyrimifluben 6%,

[0029] Styrene phenol ethoxylate 5%,

[0030] Sodium lignosulfonate 5-8%,

[0031] Organic bentonite 5-7%,

[0032] Refined soybean oil to 100%.

[0033] 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% to pass through a 1-5um filter sieve and then discharged to produce 8% penoxsulam pyrimidine with good fluidity Fenugreek Oil Suspension Concentrate.

[0034] This example is used to prevent and control annual weeds in direct-seeding rice fields: statistics are made on gramineous weeds, se...

Embodiment 2

[0038] Example 2 (20% penoxsulam·pyrimiflubac water dispersible granules):

[0039] Penoxsulam 5%,

[0040] Pyriflubac 15%,

[0041] Sodium Lauryl Sulfate 4%,

[0042] Carboxylate 5%,

[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% penoxsulam·pyrimiflubac water-dispersible granules.

[0046] This example is used to prevent and control annual weeds in rice seedling throwing fields: statistics are made on gramineous weeds, sedge weeds and broad-leaved weeds. There are 4 treatments in the experiment, and treatment 1 is 20% penoxsulam. Pyrimifluben water-dispersible granules, treatment 2 was a single dose of 10% penoxsulam water...

Embodiment 3

[0050] Example 3 (25% penoxsulam·pyrimifluor wettable powder):

[0051] Penoxsulam 5%,

[0052] Pyriflufen 20%,

[0053] Sodium Lauryl Sulfate 2%,

[0054] Sodium butylnaphthalene sulfonate 3%,

[0055] Calcium Lignosulfonate 5%,

[0056] Silica 5%,

[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. Penoxsulam · Pyriflubac wettable powder.

[0059] This example is used to prevent and control annual weeds in rice seedling-throwing fields: make statistics on gramineous weeds, sedge weeds, and broad-leaved weeds. There are 4 treatments in the experiment, treatment 1 is 25% penoxsulam·pyrimifluzide wettable powder, treatment 2 is a single dose of 10% penoxsulam wettable powder, treatment 3 is a single dose of 10% pyrimiazide Ether wettable powder, treatment 4 was the control (no application of pesticides...

Abstract

The invention relates to a weeding composition containing active components of penoxsulam and pyriminobac-methyl in a weight ratio of 8:1-1:16. The weeding composition provided by the invention has the advantage that compound of penoxsulam and pyriminobac-methyl improves weeding effect, expands weed control spectrum, reduces resistance risk caused by single usage of penoxsulam or pyriminobac-methyl, realizes low toxicity and low residual, substantially reduces drugs dose, drug frequency and usage cost; and the weeding composition is a novel composition suitable for controlling annual weeds in rice fields.

Description

technical field [0001] The invention belongs to the technical field of pesticide weeding, and relates to a herbicidal composition with penoxsulam and pyrifluconid as active ingredients, which is suitable for controlling annual 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 requirements. Since the development of pesticides in my country has just started,...
