Abstract
The invention relates to a synergistic bactericidal composition containing benziothiazolinone and tricyclazole. The synergistic bactericidal composition presents strong antibacterial and bactericidal activities on magnaporthe grisea, has the efficacies of prevention, elimination and control, is applied to agricultural production of rice, and plays an important role in increasing the yield of rice. The synergistic bactericidal composition can postpone generation of drug resistance, is safe in use and convenient to popularize, increases the yield and guarantees the harvest. The synergistic bactericidal composition containing benziothiazolinone and tricyclazole is characterized by being composed of benziothiazolinone and tricyclazole as active components, and the raw materials in percentage by weight for preparing the bactericidal composition are 2-7% of benziothiazolinone and 40-70% of tricyclazole. The synergistic bactericidal composition is prepared into wettable powder or a suspension agent.
Description
Technical field
What the present invention relates to is a kind of Synergistic bactericidal composition containing benziothiazolinone and tricyclazole, show the extremely strong antibacterial and bactericidal activity of rice Pyricularia grisea, there is prevention, root out, therapeutic efficiency, be applied to agricultural rice produce in, increasing production of rice is increased income and plays an important role.This Synergistic bactericidal composition is different from other microbicide compositions existing, can delay drug-fast generation, use safety, increase production without increasing the work force, and is convenient to promote.
Background technology
Rice blast endangers disease the most serious in Rice Production, and paddy fields, the whole world nearly all has secondary disease to occur, and distributes very extensive.Its extent of injury is in the popular time, and general underproduction 10-20%, serious reaches more than 45-50%, and chemical control is the important means of control rice blast.At present, agriculturally conventional agricultural chemicals such as Isoprothiolane, iprobenfos, kitazine, Hinosan etc. have produced more serious resistance all, China widelys popularize the special effect agent of tricyclazole as lower-cost control rice blast, through using for many years, achieves good effect.
Benziothiazolinone (Benziothiazolinone) belongs to different thiazoles compound, a kind of efficient, low toxicity, broad-spectrum germicide, its mechanism of action is mainly: with the anion binding of bacterium, genuine surface of cell membrane or react with sulfydryl, destroy the synthetic system of protein and cell membrane, the breeding of anti-bacteria, fungi, interference pathogen cell metabolism, make its physiologic derangement cause pathogen dead.This compound all has good control efficiency to because of bacterium, fungus-caused corps diseases.The benziothiazolinone of Shaanxi Xida Huate Science & Technology Industrial Co., Ltd.'s development and production is formally registered in first acquisition Ministry of Agriculture agricultural chemicals in 2008 as disinfectant use in agriculture, and applies.This product all has good control efficiency to the rot of crops, canker, anthracnose, scab, leaf spot, downy mildew, and fool proof to crops.
Summary of the invention
The object of this invention is to provide a kind of Synergistic bactericidal composition containing benziothiazolinone and tricyclazole; effectively become as benziothiazolinone is mixed with tricyclazole; there is obvious synergy complementation; utilize the difference of germ action site; by protecting and Uptake and translocation rice plant medicament; play prevention & protection, germ is rooted out in treatment; improve rice plant activity itself; reach increasing both production and income object; be better than benziothiazolinone and the alone effect of tricyclazole two medicaments; and also effective to the bacterial strain producing resistance, can also reduce costs.
A kind of Synergistic bactericidal composition containing benziothiazolinone and tricyclazole takes following scheme to realize: microbicide compositions is made up of active ingredient benziothiazolinone, tricyclazole, and Synergistic bactericidal composition raw materials percentage by weight is benziothiazolinone 2-7%, tricyclazole 40-70%, additive complement to 100%.
Described additive comprises dispersant, wetting agent, antifreeze, thickener, defoamer, assistant carrier.Synergistic bactericidal composition containing benziothiazolinone and tricyclazole makes wetting powder or suspending agent.
Dispersant in described additive adopts lignosulfonates, pull open one in powder, NNO, polyoxyethylene three phenetole phosphenylic acid salt, alkylnaphthalene sulfonate, alkylphenol polyoxyethylene or mixture; Wetting agent adopts alkylbenzenesulfonate; One in antifreeze employing ethylene glycol, propane diols or mixture; One in thickener employing xanthans, aluminium-magnesium silicate or mixture; Defoamer adopts silicone defoaming agent; One in inserts employing White Carbon black, precipitated calcium carbonate, kaolin, diatomite, water or mixture.
A kind of Synergistic bactericidal composition process of preparing containing benziothiazolinone and tricyclazole:
1, bactericidal composition makes wetting powder, benziothiazolinone, tricyclazole, additive is weighed by said ratio, fully mix in twin-screw stirred tank, airslide disintegrating mill is sent to after High-speed gas impacting is pulverized through conveyer, use twin-screw stirred tank mix and blend 30 minutes again, through being up to the standards, namely obtain the large packaging of finished product, finished product meets or higher than the indices mandatory requirement of country to wetting powder.
2, bactericidal composition makes suspending agent, dispersant, the assistant carrier in benziothiazolinone, tricyclazole, interpolation is weighed by said ratio, 1 hour is fully mixed with a high-speed stirred still, first after coarse sand grinding machine evenly grinds, then grind through fine sand grinding machine, then the thickener added under stirring with another high-speed stirred still in additive and antifreeze, stir again 1 hour, through being up to the standards, namely obtain finished product, finished product meets the indices requirement of country to suspending agent.
A kind of Synergistic bactericidal composition containing benziothiazolinone and tricyclazole is preventing and treating the application in rice disease.A kind of Synergistic bactericidal composition containing benziothiazolinone and tricyclazole; be different from other antimicrobial combination; active ingredient benziothiazolinone is mixed with tricyclazole; there is obvious synergy complementation; utilize the difference of germ action site; by protecting and Uptake and translocation rice plant medicament; play prevention & protection, germ is rooted out in treatment; improve rice plant activity itself; reach the object of increasing both production and income; be better than benziothiazolinone, tricyclazole and separately plant the alone effect of medicament, and also effective to the bacterial strain producing resistance, can also reduce costs.
