Description

A kind of prothioconazoles-Tebuconazole micro-capsule suspension and preparation method thereof
Technical field
The invention belongs to bactericide field, and in particular to a kind of prothioconazoles-Tebuconazole micro-capsule suspension and its preparation Method.
Background technology
It is well known that growth of the disease to crops has very big harm, and agricultural chemicals rises in preventing and treating plant disease pest, disease Main function.In recent years, the average annual Pesticide use amount in China is excessive, and wherein majority is chemical pesticide, thus caused by environment it is dirty Dye and food-safety problem are increasingly serious, endanger the health of the mankind, it is seen that less toxic, efficient, the environment-friendly novel agrochemical of exploitation It is the main outlet for realizing agricultural product security.
Prothioconazoles are a kind of New-type wide-spectrum triazolinthione series bactericidal agents that Beyer Co., Ltd develops, and its mechanism of action is suppression The demethylation effect of precursor-lanosterol of sterol, i.e. demethylation inhibitors (DMIs) in fungi processed.Prothioconazoles are not only With good systemic activity, excellent protection, treat and root out activity, and the lasting period is grown.Tried by substantial amounts of field efficacy Test, the results showed that prothioconazoles not only have good security to crop, and preventing disease theraping effect is good, and increase production substantially, together Triazole bactericidal agent is compared, and prothioconazoles have broader spectrum of bactericidal activity;It is mainly used in preventing and treating cereal crop such as wheat, big Numerous diseases such as wheat, rape, peanut, rice and legume crop.Moreover, prothioconazoles almost have very well to all wheat class diseases Prevention effect, such as the powdery mildew of wheat and barley, banded sclerotial blight, droop, leaf spot, rust, sclerotiniose, net blotch, moire Disease etc..Prothioconazoles can also prevent and treat the soil-borne disease of oily Lay and peanut, such as sclerotiniose, and main foliage disease, as gray mold, Black spot, brown spot, balck shank, sclerotiniose and rust etc..
Tebuconazole is a kind of efficient, wide spectrum, absorbability triazole type sterilization pesticide, has and protects, treats, rooting out three big work( Can, wide sterilization spectrum, lasting period length.As all triazole bactericidal agents, Tebuconazole can suppress the ergosterol of fungi Biosynthesis so that germ can not form cell membrane, so as to kill germ.Tebuconazole is used as seed treatment in worldwide Agent and foliar spray, wide sterilization spectrum, not only activity is high, and the lasting period is grown;It is mainly used in preventing and treating wheat, rice, peanut, vegetable A variety of fungal diseases on the crops such as dish, banana, apple, pears and corn and Chinese sorghum, its kind more than 60 in more than 50 countries in the whole world Obtained on crop and register and obtain extensive use.Tebuconazole is used to prevent and treat sclerotinia sclerotiorum, and not only preventive effect is good, and with anti-fall Volt, the features such as production-increasing function is obvious.
However, in actual applications, there are some defects in prothioconazoles, the independent dispenser of Tebuconazole or compounding use, For example, agricultural chemicals quick-acting is not good enough, overall usage amount is excessive, and the lasting period falls short of, the technical problems such as spraying times are excessive.
Pesticide micro capsule suspending agent refers to form the small appearance of nucleocapsid structure using natural or synthesis high polymer material Device, by agricultural chemicals cladding wherein, and it is suspended in the formulations of pesticide in water.It includes cyst wall and capsule-core two parts, and capsule-core is that agricultural chemicals has It is the high polymer material of film forming to imitate composition and solvent, cyst wall.This formulation is divided into continuous phase and discontinuous phase, continuous phase be water and Auxiliary agent, discontinuous phase are the agricultural chemicals tiny capsules being wrapped by.Microcapsule method is an important application in prepared by the formulations of pesticide Technology, compared with conventional pesticide technology, microcapsules have protection core material material exempt from it is influenced by environmental conditions, make pesticide activity The decomposition rate of composition slows down, reduces pesticide activity component volatilization loss, so as to obtain the utilization rate for improving active component, extends Its lasting period, the advantages that reducing the number and frequency of dispenser.
The content of the invention
In order to overcome shortcomings and deficiencies present in above-mentioned prior art, inventor is answered prothioconazoles and Tebuconazole Match somebody with somebody, using prothioconazoles-Tebuconazole after compounding as the active ingredient of the micro-capsule suspension, also, inventor intends fully profit With this one dosage type low temperature of micro-capsule suspension, a kind of significant prothioconazoles of synergistic effect-Tebuconazole micro-capsule suspension is prepared, and Obtain excellent prevention effect.
Pesticide micro capsule suspending agent mainly has following four advantages in itself:First, introduce sustained release and control release skill Art, the agricultural chemicals lasting period is extended, reduce dispenser quantity and frequency, improved the utilization rate of agricultural chemicals, save pesticide dosage;The Two, be prepared into the stability that agricultural chemicals can be improved after microcapsule formulations, avoid caused by environmental factor and other chemical substances effectively into Point decomposition, oxidation, loss etc.;3rd, oil phase is separated from the water, to the agricultural chemicals of some water unstables, then can be processed into Microcapsule formulations, expand the use range of agricultural chemicals, improve the compounding capacity with other agricultural chemicals;4th, microcapsule formulations can suppress agriculture The volatility of medicine, shelters offending smell, reduces poisoning of the agricultural chemicals to the toxicity of people, animal and other animals and to crop, subtracts Gently to the pressure of environment.
Therefore, the first aspect of the present invention provides a kind of prothioconazoles-Tebuconazole micro-capsule suspension, the rosickyite bacterium Azoles-Tebuconazole micro-capsule suspension includes following each component by mass percentage:Prothioconazoles:1%~20%, Tebuconazole: 1%~40%;Cyst material:6%~10%;Capsule-core solvent:15%~20%;Emulsifying agent:1%~5%;Thickener:0.1% ~1%;Dispersant:3%~5%;Antifreezing agent:1%~5%;Preservative:0.1%~0.5%;PH adjusting agent:1%~3%; Surplus is water.Wherein, the water is preferably deionization soft water.
Preferably, in above-mentioned prothioconazoles-Tebuconazole micro-capsule suspension, the cyst material is selected from following any It is or a variety of:Arabic gelatin, gum arabic, Lauxite, isocyanates, polyamine.
