Embodiment 1

[0023] Example 1 (80% bentazone·pyrifluaclofen water dispersible granule):

[0024] Benedazone 78%,

[0025] Pyrimifluben 2%,

[0026] Sodium Lauryl Sulfate 5%,

[0027] Carboxylate 6%,

[0028] Kaolin up to 100%.

[0029] 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 80% bentazone-pyrimifluoride water-dispersible granules.

[0030] This embodiment is used to control barnyardgrass, Cyperaceae weeds and annual broad-leaved weeds in rice throwing field: statistics are made on barnyardgrass, Cyperaceae weeds and annual broad-leaved weeds, and 4 treatments are set up in the experiment. 1 was 80% bentazone·pyrimifluben water-dispersible granules, treatment 2 was 80% bentazone water-dispersib...

Embodiment 2

[0033] Example 2 (80% bentazone-pyrimachlor wettable powder):

[0034] Benedazone 78%,

[0035] Pyrimifluben 2%,

[0036] Sodium Lauryl Sulfate 3%,

[0037] Sodium butylnaphthalene sulfonate 3%,

[0038] Calcium Lignosulfonate 5%,

[0039] Silica 4%,

[0040] Kaolin up to 100%.

[0041] 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. Benazone-Pyrizachlor wettable powder.

[0042] This example is used to control barnyardgrass, Cyperaceae weeds and annual broad-leaved weeds in transplanted rice fields: statistics are made on Barnyard grass, Cyperaceae weeds and annual broad-leaved weeds. A total of 4 treatments were set up in the experiment, treatment 1 was 80% bentazone-pyrimifluben WP, treatment 2 was 80% bentazone WP, treatment 3 was 10% pyriflufen WP, treatment 4 was For the control (no application of pesticides and no weeding), th...

Abstract

The invention relates to a weeding composition containing bentazone and pyriminobac-methyl. The effective components of the weed composition contain bentazone and pyriminobac-methyl. The parts-weight ratio of bentazone to pyriminobac-methyl is (50:1) to (1:6). The weeding composition has the advantages that after bentazone and pyriminobac-methyl are compounded, the weeding effect is improved, the weed control spectrum is expanded, the resistance rack caused by single use of bentazone or pyriminobac-methyl is reduced, the dosage and the use cost are reduced, and the weeding composition is suitable for controlling rice field weeds, cyperaceae weeds and annual broadleaf weeds.

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 bentazone and pyriflufen as active ingredients, which is suitable for controlling barnyardgrass, Cyperaceae weeds and annual broad-leaved weeds in paddy fields. Background technique [0002] 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, and the varieties of pesticides with independent intellectual property rights cannot meet the needs, the development of...
