Embodiment 1

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

[0027] Penoxsulam 2%,

[0028] Acylsulfuron-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 · rimsulfuron oil suspension concentrate with good flowability .

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

Embodiment 2

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

[0040] Penoxsulam 5%,

[0041] sulfuron-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·sulfuron-methyl 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 · Sulfur-methyl water-dispersible granules, treat...

Embodiment 3

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

[0052] Penoxsulam 5%,

[0053] sulfuron-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 · rimsulfuron 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 For rimsulfuron-methyl wettable powder, treatment 2 was a single dose of 10% penoxsulam wettable powder, treatment 3 was a single dose of 20% ...

Abstract

The invention relates to a penoxsulam-amidosulfuron weeding composition. Active ingredients of the weeding composition comprise penoxsulam and amidosulfuron. According to weight percentage, the weeding composition comprises 0.05%-30% of the penoxsulam, 0.1%-30% of the amidosulfuron and the balance of pesticide adjuvants. The weeding composition has the advantages that the weeding effect is improved after the penoxsulam is compounded with the amidosulfuron, the resistance risk caused by independently using the penoxsulam or the amidosulfuron is reduced, low toxicity and low residue are realized, the dosage, the use times and the use cost are obviously decreased, and the effect of the composition is obviously superior to that of each single dosage. Therefore, the penoxsulam-amidosulfuron weeding composition is a good novel composite reagent for controlling annual weeds in paddy field.

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 rimsulfuron-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 in ...
