Problems solved by technology

[0017] Weeding in paddy fields has always been a difficult problem in rice planting and management. Weed damage will cause crop yield reduction. At present, the most effective and economical method is chemical weeding, but long-term continuous high-dose use of herbicides with a single species or a single mechanism of action Leading to increasing weed resistance and resistance, weed control is becoming more and more difficult

Embodiment 1

[0040] 23% Sabaphos-Dicamba-Pyrazosulfuron-methyl Dispersible Oil Suspension Concentrate

[0041] Weigh 10% saponin, 11% dicamba, 2% pyrazosulfuron-methyl, 2% sodium alkylnaphthalene sulfonate, 4% Span-60#, 5% Nongru 2201, 1% sodium naphthalenesulfonate, 0.5% bentonite, 5% ethylene glycol, and methyl oleate are added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sand-milled with a sand mill to prepare 23% dispersible oil suspension concentrate of sabaphos-dicamba-pyrazosulfuron-methyl.

Embodiment 2

[0043] 27.75% Sapylphos-Dicamba-Pyrazosulfuron Suspending Concentrate

[0044] Weigh 12% saponin, 14% dicamba, 1.75% pyrazosulfuron-methyl, 4% sodium polycarboxylate, 2% phenylethylphenol polyoxyethylene ether phosphate, 3% sodium alkyl sulfate, 0.5% Carboxymethyl cellulose, 3% polyethylene glycol, 0.2% potassium sorbate, 1% octanol, and deionized water are added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sand-milled with a sand mill until the particle size D90 was less than 10 μm to prepare a 27.75% saponin-dicamba-pyrazosulfuron-methyl suspension concentrate.

Embodiment 3

[0046] 32.5% sapylphos, dicamba, pyrazosulfuron-methyl dispersible oil suspension concentrate

[0047] Weigh 14% saponin, 17% dicamba, 1.5% pyrazosulfuron-methyl, 2% diffusing agent NN0, 3% Nongru 700#, 8% BY-110, 1% sodium alkylsulfonate, 1% silicon Magnesium aluminum acid, 3% glycerin, and wheat oil are added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sand-milled with a sand mill to prepare 32.5% saponin-dicamba-pyrazosulfuron-methyl dispersible oil suspension concentrate.

Abstract

The invention discloses a ternary herbicide composition as well as a preparation and application thereof, and relates to the field of pesticide herbicides. The ternary herbicide composition comprisesanilofos or penoxsulam, and also comprises dicamba and pyrazosulfuron-ethyl, wherein a compounding mass ratio of the anilofos to the dicamba to the pyrazosulfuron-ethyl is (10-70):(10-50):(0.5-15), and a compounding mass ratio of the penoxsulam to the dicamba to the pyrazosulfuron-ethyl is (0.1-10):(10-50):(0.5-15). The herbicide composition provided by the invention has high efficiency, safety, low residues, low costs and synergy, is used for rice post-emergence spraying application treatment of toxic fertilizers or toxic soil and foliar spray treatment, and facilitates comprehensive treatment of crop weeds; and various herbicides in the ternary herbicide composition are scientifically matched and have a reasonable ratio, so that the herbicidal controlling spectrum is expanded, the overall control effects on the weeds are good, and three herbicides can be matched to have a synergistic effect.

Description

technical field [0001] The invention belongs to the field of pesticide herbicides, and in particular relates to a three-component herbicide composition and its preparation and application. Background technique [0002] Sand barnyard phosphorus (English common name anilofos), also known as arojin. Chemical name: O, O-dimethyl-S-4-chloro-N-isopropylphenylcarbamoyl methyl phosphorodithioate, according to China Pesticide Toxicity Classification Standards, Saparinphos is a low toxicity herbicide, The structural formula is as follows: [0003] [0004] Phosphorus is an organophosphorus selective systemic herbicide, which is absorbed through the young shoots and underground stems of plants, inhibits cell fission and extension, makes it difficult for weeds to pull out new leaves, stops growth, and finally dies. Works best on emerging weeds; less effective on established weeds. The growth of weeds stops after receiving the medicine, the leaves are dark green, sometimes decolori...
