Embodiment 1

[0023] Formulation Example 1: 65% halfluxazone-metazone-oxoxaden water-dispersible granules.

[0024] Fluclopyrid 10%, Mefentrazone 20%, Pinoxaden 35%, Alkylnaphthalene Sulfonate 5%, Formaldehyde Condensate of Sodium Naphthalene Sulfonate 5%, p-methoxy fatty amidobenzene Sulfonic acid 5%, sodium hexametaphosphate 3%, hydroxyethyl cellulose 0.5%, silicone oil 0.1%, anhydrous calcium chloride 0.1%, diatomaceous earth supplement 100%. Mix the above active ingredients, wetting agent, dispersant, disintegrant, binder, defoamer, stabilizer and solid carrier evenly, pulverize with ultra-fine jet mill, knead, and then add fluidized bed to granulate and dry Granulating, drying and sieving are performed in the machine to prepare 65% chloropyridine-mefentrazone-oxoxaden water-dispersible granules.

Embodiment 2

[0025] Formulation example 2: 50% halfluxazone-mefentrazone-oxoxaden water-dispersible granules.

[0026] Fluclopyrid 5%, Mefentrazone 15%, Pinoxaden 30%, Sodium Lauryl Sulfate 5%, Dibutylnaphthalene Sulfonic Acid Formaldehyde Condensate 5%, P-Methoxy Fatty Amidobenzene Sulfonic Acid 5% %, sodium hexametaphosphate 3%, polyvinyl acetate 0.5%, capric acid 0.1%, anhydrous calcium chloride 0.1%, and diatomaceous earth make up 100%. Mix the above active ingredients, wetting agent, dispersant, disintegrant, binder, defoamer, stabilizer and solid carrier evenly, pulverize with ultra-fine jet mill, knead, and then add fluidized bed to granulate and dry Granulating, drying and sieving in the machine can prepare 50% halflufenid-mefentrazone-oxoxaden water dispersible granule.

Embodiment 3

[0027] Formulation example 3: 80% wettable powder of haclopyrid, mefentrazone, pinoxaden.

[0028] Fluclopyrid 20%, Mefentrazone 30%, Pinoxaden 30%, Dioctyl Sulfosuccinate Sodium Salt 3%, Sodium Butyl Naphthalene Sulfonate 5%, P-Methoxy Fatty Aminobenzene Sulfonate Acid 5%, attapulgite make up 100%. Mix the above effective ingredients, wetting agent, dispersant and solid carrier, mechanically pulverize and then airflow pulverize, and mix uniformly to prepare 80% fluclopyrid-mefentrazone-oxoxaden wettable powder.

Abstract

The invention relates to a weeding composition containing fluorochloropyridyl ester, carfentrazone-ethyl and pinoxaden. The active ingredients of the weeding composition are fluorochloropyridyl ester, carfentrazone-ethyl and pinoxaden; the weight ratio of fluorochloropyridyl ester to carfentrazone-ethyl to pinoxaden, is (1-10): (1-20): (1-35). The weeding composition has synergetic effect, and is obviously superior to one independently used single agent in the effect of preventing and weeding annular weeds in a wheat field; the weed control spectrum is expanded, and meanwhile, the dosage of pesticide is reduced, the pollution on the environment is reduced, and the drug resistance of the weeds is delayed.

Description

technical field [0001] The invention relates to a pesticide herbicidal composition and its application field, in particular to a herbicidal composition containing halfluxazone, mefentrazone and pinoxaden as active ingredients, which is mainly used for controlling annual weeds in wheat fields. Background technique [0002] At present, chemical control is still the most important means in the comprehensive management of farmland weed damage. However, long-term continuous high-dose application of a single chemical herbicide is likely to cause environmental pollution, phytotoxicity to crops, and weeds are prone to resistance. At the same time, due to the complex grass phase and various types of weeds in the field, such as grass weeds, broad-leaved weeds and other weeds, the use of a single species can no longer effectively solve this problem, and it will show a certain aspect. Defects. Reasonable compounding of chemical herbicides has many advantages such as expanding the herb...
