Embodiment 1

[0022] Example 1: 60% pyrifluzal-promethazone-sulfuron-flucarbazone water-dispersible granule.

[0023] Pyrimifluzide 20%, Promethazone 30%, Flucarbazone Sulfame 10%, Alkylbenzenesulfonate Polyoxyethylene Triphenylene Phenyl Phosphate 10%, Sodium Polyacrylate 5%, Glycerin Fatty Acetate polyoxyethylene ether 10%, succinic acid 2%, hydroxypropyl cellulose 2%, white carbon black 5%, attapulgite make 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 sieve to obtain 60% pyriflufen-promethazone-sulfuron-sulfazone water-dispersible granules.

Embodiment 2

[0024] Example 2: 75% wettable powder of pyriflufen-promethazone-methyl-flucarbazone.

[0025] Pyrimifluzide 20%, Promasulfuron-methyl 40%, Flucarbazone Sulfame 15%, Calcium Dodecyl Benzene Sulfonate 5%, Naphthalene Sulfonate Formaldehyde Condensate Sodium Salt 5%, White Carbon Black 5%, Diatomaceous earth makes up 100%. Mix the above-mentioned active ingredients, wetting agent, dispersant and solid carrier, mechanically pulverize, then airflow pulverize, and mix uniformly to obtain 75% pyriflumefen-promethazone-methyl-flucarbazone wettable powder .

Embodiment 3

[0026] Example 3: 20% dispersible oil suspension concentrate of pyriflufen-promethazone-methyl-flumezone-sulam.

[0027] Pyrimifluzide 4%, Promethazone-methyl 10%, Flucarbazone Sulfame 6%, Sodium Isopropyl Naphthalene Sulfonate 10%, Glycerin Fatty Acid Ester Polyoxyethylene Ether 5%, Polycondensation of Alkyl Naphthalene Sulfonate 10% polyvinyl alcohol, 2% polyvinyl alcohol, 5% methyl oleate, and 100% epoxy soybean 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 medium can be prepared 20% Pyrimifluben · Promasulfuron · Flucarbazone Sulfame Dispersible Oil Suspension Concentrate.

Abstract

The invention discloses a weeding composition prepared from pyriminobac-methyl, propyrisulfuron and triafamone. Effective components of the weeding composition are the pyriminobac-methyl, the propyrisulfuron and the triafamone; the weight ratio of the pyriminobac-methyl to the propyrisulfuron to the triafamone is (1-30):(1-40):(1-20), and the weight percentage of the total weight of the pyriminobac-methyl, the propyrisulfuron and the triafamone to the weight of the weeding composition is 0.5 percent-85 percent. The weeding composition has a remarkable synergistic effect, and is mainly applied to prevention and control of rice field weeds; a weeding effect is obviously improved compared with that by separately using each single agent, a herbicide controlling spectrum is enlarged, meanwhile the usage amount of a pesticide is lowered, pollution to environment is alleviated, generation of drug resistance of the weeds is delayed, and the service life of the pesticide is prolonged.

Description

technical field [0001] The invention relates to an agricultural herbicide, the active ingredients of which are pyriflubac-methyl, promethazone-methyl and flucarbazone-sulam, which are used for controlling weeds in paddy fields. Background technique [0002] Pyriminobac-methyl: belongs to pyrimidine salicylic acid herbicides, it can be absorbed through the stems, leaves and roots of weeds, and quickly spread to the whole plant, inhibiting the biosynthesis of acetolactate synthase and amino acids, thereby inhibiting And hinder the cell division in weeds, stop the growth of weeds, and eventually make the weeds albino and die. It has special effects on barnyardgrass in paddy fields and is extremely safe to rice. [0003] Propyrisulfuron (propyrisulfuron): belongs to pyrimidinyl sulfonylurea herbicides, mainly used in rice fields to control gramineous and broad-leaved weeds such as barnyardgrass. The product is used at a low dosage and is effective against certain weeds that ar...
