Abstract
The germicide composite mainly consists of bavistin 5-30%, triazolone 1.5-15.0%, sulphur 10-35%, dispersant 0.1-1.0%, emulsifier 3.0-10.0%, anti-bubbling agent 0.1-1.0% and water, and it may contain densifier in 0.2-1.0% and antifreezer in 2-6%. It can be used for prevention and control of several diseases of wheat, rice, beet, vegetable, fruit, peanut, rubber tree, etc. with obvious yield-increasing effect.
Description
The present invention relates to a kind of microbicide compositions of controlling plant diseases, particularly the suspending agent of bactericide and sulphur mixing.
Before the present invention makes, the multiple diseases that two kinds of bactericide of carbendazim and triazolone (triadimefon) are usually used in preventing and treating crop, its single agent has wetting powder, suspending agent (colloidal suspending agent) or missible oil.These preparations have the better prevention effect to some disease of crop, be used to prevent and treat wheat scab, cercospora leaf spot of sugar beet, cucurbits powdery mildew, leaf spot of peanut as carbendazol wettable powder or colloidal suspending agent, rust and powdery mildew that the triazolone preparation is used to prevent and treat crop such as wheat, vegetables all once had remarkable prevention effect.But the general manufacturing cost of these single agent is higher, cost an arm and a leg, and long-term use is easy to develop immunity to drugs, service life is short.It is reported that (plant protection journal 1982,9 (2): 131-136), carbendazim obviously descends, proves conclusively in the drug effect of preventing and treating diseases such as powdery mildew of cucumber, cercospora leaf spot of sugar beet and produced pesticide resistance.In recent years, both at home and abroad agricultural chemicals circle begin to utilize cheap, become various preparations from non-resistant and the double sulphur of controlling of sick worm with bactericide compounded, thereby reduce cost and toxicity of pesticide, keep medicine original to imitate and delay drug-fast development speed, commonly used have a Switzerland Wyss Samen﹠amp; The Fungizid stop that Pflanzen company produces, 63% wetting powder (sulphur+carbendazim=51+12%), 40% sulphur-carbendazim the colloidal suspending agent (20+20%) of Chemical Industry Inst., Guangzhou City development, the Bayletor kombat PB that Germany Bayer company produces, (sulphur+triazolone=50+2%) waits preparation to 52% wetting powder.These single agent or sulphur mix preparation range of application are narrower, and be poor to the rust control efficiency as the carbendazim preparation, not outstanding to the powdery mildew control efficiency, and its sulphur mix preparation is also significantly little to the control efficiency of rust.Triazolone-sulphur mix preparation or single agent are not remarkable to the control efficiency of fungal diseases such as sac fungis such as the carbon jaundice disease of crop, leaf spot and imperfect fungus.Triazolone and carbendazim mix preparation, as triazolone-carbendazol wettable powder (5+35%) that Dongtai City's agricultural chemicals factory in China Jiangsu Province produces, though range of application is wider, cost is higher, environmental pollution is also bigger.
The purpose of this invention is to provide a kind of plant multiple diseases of preventing and treating, have the microbicide compositions of the advantage of carbendazim, triazolone and the various preparations of sulphur concurrently.This be a kind of be dispersion medium, good stability with water, toxicity is low and drug effect significantly, synergistic effect, applied range, with low cost, the simple agricultural chemicals suspension agent of manufacturing process arranged.
Technical scheme of the present invention is such: with carbendazim, triazolone and sulphur is that solvent and auxiliary agent and water are mixed in the sand milling jar, again through the sand mill dispersion grinding to fineness below 5 microns, become even flowable suspension.The component of suspension contains (percentage by weight):
Carbendazim 5-30%
Triazolone 1.5-15.0%
Sulphur 10-35%
Dispersant 0.1-1.0%
Emulsifier 3.0-10.0%
Defoamer 0.1-1.0%
Water adds to 100%
Wherein, dispersant such as wooden malicious sulfoacid calcium, methylene bis sodium naphthalene sulfonate, fatty alcohol-polyoxyethylene ether or its mixture.Emulsifier is calcium dodecyl benzene sulfonate, alkyl phenol formaldehyde resin polyoxyethylene ether, styryl phenyl polyoxy ethyl ether, cumenyl phenethyl phenol APEO or its mixture.Defoamer is organic silicone oil or isooctanol.In above-mentioned prescription, can also add the thickener polyvinyl alcohol of 0.2-1.0% or xanthans etc., add the antifreeze glycol of 2-6% or propane diols etc.
The present composition is through toxicological test, and rat peroral acute toxicity LD509432 milligram/kilogram through skin acute toxicity LD50＞12400 milligram/kilogram, belongs to low toxicity level.
The present composition shows through laboratory test with through the field application test, compare with prior art formulations, the diseases of wheat, beet, paddy rice and other crops is had better control efficiency and doublely controls effect, and synergistic effect is obvious, can promote plant growth, anti-early ageing and obvious effect of increasing production.

The present composition has been gathered the advantage of carbendazim, triazolone and sulphur, also has synergistic effect, can be widely used in preventing and treating fungal disease on the various crop such as wheat, paddy rice, fruit tree, vegetables, beet, peanut and bamboo grows, plant disease especially for the same crop Zhiduo County of can holding concurrently simultaneously, obvious effect of increasing production, and can delay the drug-fast generation and the speed of development, prolong the service life of carbendazim and triazolone.Carbendazim, sulphur and triazolone have nothing in common with each other to the mechanism of action of fungi, and carbendazim mainly acts on the metabolic process of protein among the fungal cell, and DNA's is synthetic in the interference cell, is systemic fungicide.During dispenser, carbendazim penetrates in the plant corpus from the dispenser position, adheres on the interior SMT protein of cell nucleus, suppresses mycelial growth and growth.Triazolone also is a kind of systemic fungicide, and main effect is the metabolism of disturbing whole germ cell, and sterol is synthetic in the inhibition cell.Sulphur mainly acts on fungal cell's OR process as protective fungicide, disturbs the metabolism of fungi energy, and the prevention pathogen is invaded and does in the object, and certain bactericidal insecticidal activity is arranged.Mix this three kinds of medicaments, except that each medicament separately the effect to pathogen; Also exist the interaction between the various bactericide and use the combined influence of back, thereby have synergistic effect, and enlarged the scope of application crop.Simultaneously, mix the medicament of these three kinds of different mechanism of action, can also in time root out the few drug-fast strain of quantity in the pathogen population, alleviate the selection pressure of tool pesticide resistance fungus strain, thereby prevent drug-fast generation, delay the speed of development of drug resistance.
The present composition has also that processing technology is simple, constant product quality, good dispersion, suspensibility height, plate-out ability is good and adhesion strength is strong characteristics, energy resistance of rainwater washing against, lasting medicine.The amount ratio list agent of present composition organic agricultural chemicals reduces, and utilizes more inexpensive sulphur, and is dispersion medium with water, has not only reduced manufacturing cost and use cost, has also reduced toxicity, reduces the pollution to environment.
