Embodiment 1

[0022] Example 1 (80% penoxsulam · pentaclofen water dispersible granules).

[0023]

[0024] 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, it is dried and sieved to obtain 80% penoxsulam · penoxafen water-dispersible granules .

[0025] This example is used to prevent and control annual weeds in rice seedling throwing fields: annual grass weeds, Cyperaceae weeds and broad-leaved weeds are counted, and the application time is 10 days after rice seedling throwing. The weeds are about 1 leaf stage, and the method of application is the poisonous soil method, and about 10 kg of fine moistened soil is applied per acre. A total of 5 treatments were set up in the experiment, treatment 1 was 80% penoxsulam · penoxafen ...

Embodiment 2

[0030] Example 2 (80% penoxsulam · penoxafen wettable powder).

[0031]

[0032]

[0033] 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·Cyclofenac WP.

[0034] This embodiment is used to prevent and treat annual weeds in rice transplanting fields: annual grass weeds, Cyperaceae weeds, and broad-leaved weeds are counted, and the application time is 7 days after rice transplanting, and the weeds have not emerged. The method of application is the poisonous soil method, and about 10 kg of fine moistened soil is mixed per acre. A total of 5 treatments were set up in the experiment, treatment 1 was 80% penoxsulam · penoxafen wettable powder, treatment 2 was 20% penoxsulam wettable powder, treatment 3 was 40% penoxafen Wet powder, treatment 4 is 50% fenthiazamide · pyrazosulfuron-methyl wettable powder, treatment 5 is the control...

Embodiment 3

[0039] Example 3 (1.6% penoxsulam · penoxafen granules).

[0040]

[0041] Put the above materials together into the conical mixer and mix them evenly, then pulverize them through the jet mill, and then mix the pulverized materials through the conical mixer. powder. Put this wettable powder into a disc granulator, add water to granulate, and then dry in a drying cylinder, sieve, and cool in a cooling cylinder to prepare 1.6% penoxsulam·cyclafenfen granules.

[0042] This embodiment is used to prevent and eliminate annual weeds in rice transplanted fields: annual grass weeds, Cyperaceae weeds and broad-leaved weeds are counted, and the application time is 14 days after rice transplanting, and the weeds are partially unearthed. The older barnyard grass is about 2 leaves stage, and the broad-leaved weeds have about 1 leaf and 1 heart. The method of application is broadcasting. There were 5 treatments in the experiment, treatment 1 was 1.2% penoxsulam · penoxafen granules, tr...

Abstract

The invention relates to a weeding composition containing penoxsulam and pyriftalid. The weeding composition comprises the active ingredients of penoxsulam and pyriftalid, wherein the ratio of the penoxsulam to the pyriftalid in the weeding composition in parts by weight is (5:1) to (1:16), preferably (3:1) to (1:12). The weeding composition has the advantages that the weeding effect is improved after the penoxsulam and the pyriftalid are compounded; a herbicide controlling spectrum is expanded; the medication time range is expanded relative to the conventional sealants; the resistance risk caused by single use of the penoxsulam or the pyriftalid is reduced; the weeding composition is low in toxicity and low in residue, and suitable for preventing and killing annual weeds of a paddy field; the dosage and the use cost are reduced.

Description

technical field [0001] The invention belongs to the technical field of agricultural weeding, and in particular relates to a paddy field herbicidal composition which uses penoxsulam and cyclopyrafen as active ingredients. Background technique [0002] With the phase-out of highly toxic pesticides, new pesticides 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 chemicals are getting higher and higher. It is necessary for 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, and the varieties of pesticides with independent intellectual property rights cannot meet the needs, the development of new pesticide mixed preparations is the only way for the current development of pestic...
