Problems solved by technology

[0005] Penoxsulam belongs to the class of triazolopyrimidine sulfonamide herbicides. It works by inhibiting acetolactate synthase (ALS). It is absorbed through the leaves, sheaths, stems or roots of weeds, accumulates at the growth point, and inhibits acetylation. The synthesis of lactic acid synthase leads to the inability to synthesize branched-chain amino acids, which in turn affects protein synthesis and weed cell division, causing weeds to stop growing and then die.
It has a certain control effect on barnyard grass, but it is poor, and it is ineffective against Qianjinzi

Embodiment 1

[0028] Example 1 55% penoxsulam-merifenamide-pyrazosulfuron-methyl wettable powder

[0029] Penoxsulam 1%, Benthiazamide 52%, Pyrazosulfuron-methyl 2%, Sodium Lignosulfonate 10%, Sodium Dodecylbenzenesulfonate 8%, Kaolin added to 100%, according to the above The formula weighs each component, bis-pentoxsulam, mefenamide, pyrazosulfuron-methyl, dispersant (sodium lignosulfonate), wetting agent (sodium dodecylbenzenesulfonate), filler (Kaolin) are added to the cone mixer and mixed evenly, and the evenly mixed material is added to the jet mill for crushing, and then mixed evenly, sieved, and the fineness reaches 98%. Passing through a 325-mesh standard sieve, 55% Penoxsulam-Methiazamide-Pyrazosulfuron-methyl wettable powder products. The suspension rate of penoxsulam in the 55% ternary compound wettable powder was tested: 91%, the suspension rate of mefenacet: 92%, the suspension rate of pyrazosulfuron-methyl: 92%; wettability ≤ 80 seconds .

Embodiment 2

[0030] Example 2 56% penoxsulam-merifenamide-pyrazosulfuron-methyl wettable powder

[0031] Penoxsulam 2%, Thienacet 52%, Pyrazosulfuron-methyl 2%, Sodium Lignosulfonate 7%, Dispersant NNO 8%, Sodium Dodecyl Benzene Sulfonate 8%, Diatom Soil 5%, light calcium carbonate was added to 100%, the preparation method was the same as in Example 1, and 56% penoxsulam-fenthiazamide-pyrazosulfuron-methyl wettable powder was obtained.

[0032] The 56% ternary compound wettable powder has a penoxsulam suspension rate of 91%, mefenacet suspension rate of 93%, and pyrazosulfuron-methyl suspension rate of 90%; wettability ≤ 80 seconds.

Embodiment 3

[0033] Example 3 42.5% penoxsulam-merifenacet-pyrazosulfuron-methyl wettable powder

[0034]Penoxsulam 1%, Benifenamide 39%, Pyrazosulfuron-methyl 2.5%, Nonylphenol Polyoxyethylene Ether 2%, Dispersant NNO 2%, Sodium Lignosulfonate 5%, Dodecyl 6% sodium alkylbenzene sulfonate, 15% kaolin, and bentonite were added to 100%. The preparation method was the same as in Example 1 to obtain 42.5% penoxsulam-fenthiazide-pyrazosulfuron-methyl wettable powder.

[0035] The 42.5% ternary compound wettable powder has a suspension rate of penoxsulam: 94%, mefenacet: 91%, pyrazosulfuron-methyl: 95%; wettability ≤ 80 seconds.

Abstract

The invention belongs to the technical field of pesticides and discloses a wettable powder containing penoxsulam, mefenacet and pyrazosulfuron-ethyl. The wettable powder is prepared with the penoxsulam, the mefenacet and the pyrazosulfuron-ethyl as main active components according to the mass ratio of 0.1-40:0.1-80:0.1-60. The total mass percentage content of the penoxsulam, the mefenacet and the pyrazosulfuron-ethyl in the wettable powder is 1-80%. The aqueous agent also includes 1-20% of a dispersing agent, 1-10% of a wetting agent and the balanced being filling materials. The invention also discloses an application of the wettable powder in prevention and removal of weeds in paddy fields. By means of combination of the herbicides, the wettable powder is enlarged in weeding spectrum and is improved in weeding effects, has an outstanding preventing and treating effects on gramineous weeds, cyperaceae weeds and broadleaved weeds, is quick in effects, is long in lasting period, can delay drug resistance, is completely in weeding, is low in residue, is low in toxicity and is safe and environmental-protective.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to a herbicide, in particular to a wettable powder containing penoxsulam, mefenacet and pyrazosulfuron-methyl and an application thereof. Background technique [0002] Rice is one of the main food crops in my country, and weeding in rice fields is a major problem in production. Chemical weeding is currently the main means of controlling weeds. In recent years, due to the large-scale use of some herbicide varieties alone, many weeds have developed resistance. At the same time, because weeds occur with complex grass phases and various types, the use of a single species can no longer effectively solve farmland weeds, and all will show a certain aspect of defects. At present, there are many kinds of herbicides on the market, and at the same time, the application technology is also demanding. If there is a little carelessness in the application, problems such as phytotoxicity and poor ...
