Embodiment 1

[0026] Example 1 (8% penoxsulam·cyprosulfuron oil suspension):

[0027] Penoxsulam 2%,

[0028] Cyprosulfuron-methyl 6%,

[0029] Styrene phenol ethoxylate 5%,

[0030] Sodium Lignosulfonate 8%,

[0031] Epoxidized soybean oil 5%,

[0032] Organic bentonite 5%,

[0033] Refined soybean oil to 100%.

[0034] Put the above materials (except organic bentonite) into the reaction kettle 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% through 1- After 5um, the material is discharged, and the material is put into a high-shear emulsification kettle together with the pre-dissolved organic bentonite. After emulsification, it can be made into 8% penoxsulam·cyprosulfuron oil suspension with good flowability agent.

[0035] This example is used to prevent and control annual weeds in direct-seeded rice fields: the test is carried out in ...

Embodiment 2

[0039] Example 2 (20% penoxsulam·cyprosulfuron water-dispersible granules):

[0040] Penoxsulam 5%,

[0041] Cyprosulfuron-methyl 15%,

[0042] Sodium Lauryl Sulfate 4%,

[0043] Carboxylate 5%,

[0044] Urea 40%,

[0045] Kaolin up to 100%.

[0046] 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·cyprosulfuron water-dispersible granules .

[0047] This example is used to prevent and control annual weeds in rice seedling throwing fields: the experiment is carried out in rice seedling throwing fields with many weeds, barnyardgrass and broad-leaved weeds. There are 4 treatments in the experiment, and treatment 1 is 20% penoxsulam · Cyprosulfuron-methyl water-dispersible gran...

Embodiment 3

[0051] Example 3 (15% penoxsulam·cyprosulfuron wettable powder):

[0052] Penoxsulam 5%,

[0053] Cyprosulfuron-methyl 10%,

[0054] Sodium Lauryl Sulfate 2%,

[0055] Sodium butylnaphthalene sulfonate 3%,

[0056] Calcium Lignosulfonate 5%,

[0057] Silica 5%,

[0058] Kaolin up to 100%.

[0059] Put the above materials together into the conical mixer and mix them evenly, and then pulverize them through the jet mill, and then mix the pulverized materials through the conical mixer. Penoxsulam · Cyprosulfuron wettable powder.

[0060] This example is used to prevent and control annual weeds in rice seedling throwing fields: the experiment was carried out in a rice transplanting field with many weeds such as Qianjinzi, barnyardgrass and broad-leaved weeds. There were 4 treatments in the experiment, and treatment 1 was 15% penoxsulfonate Amine Cyprosulfuron WP, treatment 2 was a single dose of 10% penoxsulam WP, treatment 3 was a single dose of 20% cyprosulfuron WP, treatm...

Abstract

The invention relates to a penoxsulam and cyclosulfamuron herbicidal composition. The composition comprises the following ingredients by weight percent: 0.01-20% of an active component penoxsulam, 0.1% to 30% of an active component cyclosulfamuron and the balance of pesticide adjuvant. The penoxsulam and cyclosulfamuron herbicidal composition has the advantages that the herbicidal effect is improved after penoxsulam and cyclosulfamuron are compounded, resistance risks resulted from single use of penoxsulam or cyclosulfamuron is reduced, toxicity is low, residue is low, the use amount of a pesticide, use frequency of the pesticide and use cost are obviously reduced, higher effect of the composition is obviously higher than that of a single dose. The penoxsulam and cyclosulfamuron herbicidal composition is a good novel composition pesticide for preventing and controlling annual grassy weeds in a paddy field at present.

Description

technical field [0001] The invention belongs to the technical field of pesticide weeding, and in particular relates to a paddy field herbicidal composition with penoxsulam and cyprosulfuron-methyl as active ingredients, which is used 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 i...
