Abstract

The invention relates to a new pesticide prepared by compounding bronopol and benzimidazole bactericide or acid salt thereofA bactericide is used. The benzimidazole bactericide is represented by a general formula , wherein R in the formula1Represents hydrogen or alkyl. R2Represents hydrogen, alkyl, alkoxy, alkylthio. R3Represents hydrogen or alkyl. The compound agent shows good synergistic performance and is suitable for preventing and killing various diseases of rice, fruit trees, vegetables and tobacco.

Description

A kind of agricultural double-crossed disinfectant
It is composite with as a kind of new disinfectant use in agriculture to the present invention relates to bronopol and benzimidazole germicide or its ackd salt.
The bronopol chemical name is a 2-bromo-2-nitro-1, ammediol.This compound is the earliest as a kind of industrial bactericide, is widely used in aspects such as water treatment, leather, papermaking, cosmetics be anticorrosion.After be developed again and be used for agricultural seed treatment.Bronopol all has high activity to most bacteriums and fungi, can kill or suppress the growth of germ under extremely low concentration fully.
The benzimidazole germicide of general formula (I) (R in the formula 1Represent hydrogen, alkyl.R 2Represent hydrogen, alkyl, alkoxyl, alkylthio group.R 3Represent hydrogen, alkyl.) be the important disinfectant use in agriculture of a class.For Saccharomyces, Dendrochium and Basidiomycotina all have effect preferably.This series bactericidal agent is used for agricultural production with the form of simple substance or strong acid salt usually, and the form of strong acid salt has better control efficiency generally speaking.
In general formula (I), with R 1Be hydrogen, R 2Be hydrogen, R 3Carbendazim for the methyl representative.With R 1Be normal-butyl, R 2Be hydrogen, R 3Benomyl for the methyl representative.With R 1Be hydrogen, R 2Be rosickyite base, R 3In agricultural production, obtained extensive use for the albendazole of methyl representative is all own.
We find to have demonstrated splendid Synergistic performance under study for action surprisingly when bronopol and benzimidazole germicide or its ackd salt are composite.Though its synergy mechanism also is not determined at present.But has potential using value undoubtedly.
The objective of the invention is to provide a kind of new by bronopol with have the benzimidazole germicide of general formula (I) or the compound sterilizing mixture of its ackd salt.R in the formula 1Represent hydrogen, alkyl.R 2Represent hydrogen, alkyl, alkoxyl, alkylthio group.R 3Represent hydrogen, alkyl.
Another object of the present invention is to provide this compound mixture type and and technology of preparing and the application in agricultural production.
A component of the composite bactericide that the present invention relates to is a bronopol, and its chemical name is a 2-bromo-2-nitro-1, ammediol.
Another component of the composite bactericide that the present invention relates to has general formula (I)
Figure A9912599800041
The benzimidazole sterilization.R in the formula 1Represent hydrogen, alkyl.R 2Represent hydrogen, alkyl, alkoxyl, alkylthio group.R 3Represent hydrogen, alkyl.That have typical meaning is carbendazim (R 1Represent hydrogen, R 2Represent hydrogen, R 3Represent methylidene).Benomyl (R 1Represent normal-butyl, R 2Represent hydrogen, R 3Represent methylidene).Albendazole (R 1Represent hydrogen, R 2Represent n-pro-pyl, R 3And its their strong acid salt represent methylidene).
The agent shape of composite bactericide of the present invention can be wetting powder, aqueous suspension agent, colloidal suspending agent, and the content of its effective ingredient bronopol (mass ratio) can be between 0.1~90%.Be preferably in 1.5~50%.The content of benzimidazole germicide (mass ratio) can be between 0.1~90%.Be preferably between 5~75%.The required auxiliary agent of using comprises carrier, wetting agent, dispersant, thickener, defoamer, crystallization inhibitor etc. during the preparation formulation.
Wherein carrier comprises silicon bath soil, kaolin, atlapulgite, white carbon etc.Its consumption can be preferably between 20~80% between 10~90%.
Wetting agent and dispersant are various in style, and common a kind of surfactant can play wetting and peptizaiton simultaneously.Wetting agent and dispersant commonly used in pesticidal preparations have lignin sulfonic acid sodium salt or calcium salt, dodecyl sodium sulfate, alkylphenol polyoxyethylene, alkylphenol polyoxyethylene phosphate (salt), oxirane and propylene oxide block polymer etc.Total consumption of wetting agent and dispersant can be preferably between 5%-10% between 3%-15%.
Thickener and defoamer are used for the preparation of colloidal suspending agent or aqueous suspension agent.Thickener commonly used has carboxymethyl cellulose, methylcellulose, polyvinyl alcohol, polyacrylamide, xanthans etc.Its consumption can be regulated as the case may be, generally is no more than 10%.Be preferably between the 0.2-5%.Defoamer can be selected silicone based defoamer, polyalcohol and ester defoamer thereof etc. for use.Its consumption is generally between 0.05%-1%.
Example one wetting powder (wt/wt)
Bronopol 20%
Benomyl 20%
Ultra-fine silicon bath soil 50%
Sodium lignin sulfonate 4%
Calcium lignosulfonate 3%
Dodecyl sodium sulfate 3%
Example two wetting powders (wt/wt)
Bronopol 10%
Carbendazim hydrochloride 40%
Ultra-fine silicon bath soil 40%
Sodium lignin sulfonate 6%
Dodecyl sodium sulfate 4%
Example three aqueous suspensions (wt/wt)
