Embodiment 1

[0022] Formulation example 1: 80% water-dispersible granules of bentazone·fenflumezone·pentoxsulam.

[0023] Benazone 60%, Metrazone 10%, Penoxsulam 10%, Aryl Sulfonate Formaldehyde Condensate 5%, Polyoxyethylene Aryl Ether 5%, Ammonium Sulfate 2%, Polyethylene Glycol 2 %, Kaolin makes up 100%. Mix the above-mentioned active ingredients, wetting agent, dispersant, disintegrant, binder and solid carrier evenly, pulverize with an ultra-fine jet mill, knead, and then add to a fluidized bed granulation dryer for granulation and drying and sieving to obtain 80% bentazone·fentrazone·pentoxsulam water dispersible granules.

Embodiment 2

[0024] Formulation example 2: 70% wettable powder of bentazone·metrazone·pentoxsulam.

[0025] 55% of bentazone, 8% of mefentrazone, 7% of penoxsulam, 10% of sulfosuccinate, 5% of polyoxyethylene aryl ether, and 100% of diatomaceous earth. Mix the above-mentioned effective ingredients, wetting agent, dispersant and solid carrier, mechanically pulverize, then airflow pulverize, and mix uniformly to prepare 70% bentazone·metrazone·pentoxsulam wettable powder.

[0026] Formulation example 3: 25% bentazone·metrazone·pentoxsulam oil suspension concentrate.

[0027] 22% bentazone, 1.5% mefentrazone, 1.5% penoxsulam, 10% n-butyl naphthalene sulfonate, 10% alkylphenol polyoxyethylene ether, 2% magnesium aluminum silicate, 100% vegetable oil %. After the above-mentioned active ingredients, wetting agent, dispersant, thickener and liquid carrier are dispersed by high-speed shearing and sand-milled in a sand mill, a highly dispersed and stable suspension system formed in a non-aqueous ...

Embodiment 1

[0036] Biological Assay Example 1: Indoor bioactivity assay.

[0037] Drugs to be tested: 95% of the original drug of bentazone, 90% of the original drug of mefentrazone and 98% of the original drug of penoxsulam.

[0038] Targets for testing: Monochoria vaginalis, Echinochloa crusgalli.

Abstract

The invention relates to weeding composition containing bentazone and carfentrazone as well as penoxsulam. The effective components of the weeding composition are bentazone and carfentrazone as well as penoxsulam, and the weight part ratio of bentazone, carfentrazone and penoxsulam is (1-40):(1-15):(1-15). The weeding composition has a synergistic effect, expands a weeding spectrum, reduces the pesticide consumption, alleviates the environmental pollution and delays the pesticide resistance of the weeds, and an effect of preventing and removing annual weeds in paddy fields is remarkably superior to that of a separately used individual weedicide.

Description

technical field [0001] The invention relates to a pesticide herbicide composition and its application field, in particular to a herbicide composition with bentazone, mefentrazone and penoxsulam as active ingredients, which is mainly used for controlling annual weeds in paddy fields. Background technique [0002] Bentazone: a selective contact-killing post-emergence herbicide, used to treat weed stems and leaves at the seedling stage. It is mainly used in rice, soybean, peanut, wheat and other crops to control broad-leaved weeds and sedge weeds, but it is ineffective against gramineous weeds. [0003] Fcarfentrazone-ethyl: is a triazolinone contact-type selective herbicide, suitable for controlling broad-leaved weeds and sedge weeds on wheat, barley, rice, corn and other crops. [0004] Penoxsulam (penoxsulam): belongs to the triazolopyrimidine sulfonamide herbicide, has good control effect on various weeds commonly seen in paddy fields, including barnyardgrass, annual sedge...
