Embodiment 1

[0022] Formulation Example 1 (6% penoxsulam·oxentrazone wettable powder).

[0023] Penoxsulam 1.5%, Fenoxam 4.5%, Sodium Dodecyl Benzene Sulfonate 4%, Sodium Lignosulfonate 3%, Talc 2%, White Carbon Black 2%, Attapulgite Supplement to 100%.

[0024] The above formula is coarsely pulverized in proportion, put into a mixer and mixed evenly, and then jet pulverized to obtain 6% penoxsulam · fenoxazone wettable powder.

Embodiment 2

[0025] Formulation Example 2 (6.9% penoxsulam · fenoxam suspension concentrate).

[0026] Penoxsulam 0.9%, Mefenpyramid 6%, Nongru 1601# 15%, p-oleamidoanisole sulfonic acid 5%, alkylphenol formaldehyde resin polyoxyethylene ether sulfate 4%, bentonite 3%, xanthan gum 0.1%, silicone 0.4%, glycerin 4%, deionized water to make up to 100%.

[0027] The above formula is pre-crushed according to the proportion, and then added to a sand mill for grinding, and then mixed by high shear to prepare a 6.9% penoxsulam·oxafen suspension concentrate.

Embodiment 3

[0028] Formulation Example 3 (15% penoxsulam·oxaflume water-dispersible granules).

[0029] Penoxsulam 2.5%, Mefenpyramid 12.5%, Sodium Lauryl Sulfate 6%, Polycarboxylate 4%, Sodium Chloride 2%, Polyethylene Glycol 3%, Kaolin to 100% .

[0030] Dry pulverize, granulate, dry, and sieve the above formula according to the proportion to prepare 15% penoxsulam·oxentrazone water-dispersible granules.

Abstract

The invention discloses a weeding composition containing penoxsulam and metamifop for a paddy field. The weight part ratio of penoxsulam to metamifop in the weeding composition is (20:1)-(1:20), and preferably (1:1)-(1:10). The prevention and control effect of the weeding composition disclosed by the invention is improved obviously compared with that of a single agent, the use dosage of pesticide is reduced, and the adverse effect of the pesticide on ecological environment is reduced; and the weeding composition has great significance in the comprehensive treatment of weed resistance, and has great economic benefit and social benefit.

Description

technical field [0001] The invention relates to a paddy field herbicide composition, which uses penoxsulam and fenpyramid as active ingredients and is used for controlling annual weeds in paddy fields. Background technique [0002] Chemical weeding is one of the main means of controlling weeds in agriculture. In recent years, due to the large-scale single use of some herbicide varieties, many weeds have developed resistance. At the same time, when weeds occur, the grass phase is complex, not only annual and perennial weeds are mixed; herbs, vines and shrubs are both present, and the emergence of weeds is uneven, and seeds, young and old weeds alternately occur. Therefore, when the herbicide species are used alone, they will show certain defects and limitations. [0003] Penoxsulam is a broad-spectrum herbicide for post-emergence paddy fields. It can effectively control barnyard grass, stephae and annual Cyperaceae weeds, and is effective against many broad-leaved weeds wit...
