Description
Technical field
The present invention relates to the agriculture chemical compounding technical field, being specifically related to a kind of is two yuan of composite pesticide sterilizing composites of active ingredient with cyproconazole and chitin.
Background technology
Cyproconazole, chemical name: 2-(4-chlorphenyl)-3-cyclopropyl-1-(1,2; The 4-triazol-1-yl) fourth-2-alcohol belongs to the triazole bactericide, is systemic fungicide; Have the effect of prevention and treatment, be ergosterol demethylation inhibitor, all effective to the mould Pseudomonas of Erysiphe, Rust, spore, Septoria, Venturia germ on cereal crop, coffee, beet fruit tree and the cucumber; Can prevent and treat cereal and coffee rust; Cereal, fruit tree and powdery mildew of cucumber, peanut, beet tops pinta, apple scab and peanut white rot.Single agent is used for a long time, and germ is prone to produce resistance.Chemical structural formula is:
Chitin has another name called chitin, chitin, chitin, and chemical name is poly-n-acetyl-D gucosamine, belongs to glycosaminoglycan, is a kind of natural polymers.At occurring in nature, it extensively is present in the arthropodan crust in ocean, also is present in the cell wall of lower animal mushroom, insect, alga cells film and higher mammal, is the second largest living resources that are only second to vegetable fiber on the earth.Chitin removes that its product is a shitosan behind the acetyl group, has another name called chitosan or soluble chitin, and its chemical name is (1,4)-2-amino-2-deoxidation-b-D glucan.Shitosan is unique positively charged animal fiber in the dietary fiber found up to now of present occurring in nature, has necessarily functional.Be described as the 6th vital principle after protein, fat, carbohydrate, vitamin and mineral salt by American-European academia.
As plant growth regulator and novel biopesticide, crust four, five, hexa polyose content carry out field experiment greater than 80% to crops such as many kinds fruit, vegetables, grains to chitin on agricultural; Aspect disease and insect resistance and the promotion growth remarkable effect is being arranged; Carry out seed dressings such as wheat, pea with the chitosan solution of molecular weight below 2000, can prevent and treat of the harm of underground mould, improve resistance against diseases seed; Lodging tolerance, raising the output can reach 10%-30%.
Simple chemical pesticide uses as single agent and has more and more satisfied not the requirement of agricultural production, and the prevention and elimination of disease and pests consumption is big, and residual height is prone to contaminated environment, and long-term use makes damage by disease and insect produce resistance easily.Biopesticide in the agricultural chemicals makes a kind of new and effective environmental protection type agricultural chemical, and chitin for example is as plant growth regulator; Act on plant itself; Improve its immunity, aspect disease and insect resistance and the promotion plant growing remarkable effect is being arranged damage by disease and insect self, and almost harmless to environment; It is unstable that but its significant drawbacks using separately is an effect, and the effect that depends on environment is bigger.As miss the drug use optimum period, or, whether can still activate resistant effect and uncontrollable in unsuitable crop vigorous growth condition phase medication.The bactericidal effect of chitin can depend on upgrowth situation and the extraneous natural environment situation of crop itself to a certain extent.But characteristics such as chitin is pollution-free basically, non agricultural chemical residuum, nuisanceless production are very friendly to environment, help the sustainable development of environment.So our bactericide through will having some characteristic and novel biopesticide is composite by a certain percentage can solve above chitin drug effect problem of unstable preferably; The new type bactericide cyproconazole has good bactericidal activity equally, and is better with the compatibility of environment.Through my research staff of company long-term scientific research in the agriculture chemical compounding field; Attempt composite with cyproconazole and chitin; Reach medication requirement efficient, stable, environmental protection,, proposed a kind of finally with new type bactericide cyproconazole and the composite composition pesticide of novel biopesticide chitin through lot of experiment validation; Effectively controlling plant diseases reduces environmental pollution.And, do not find any open research or report that relevant these two kinds of compounds are composite up to the present through preliminary search.
Summary of the invention
Based on above technical background, in order to solve some problems that run in the above agricultural production of mentioning, the chemical pesticide of efficient, low-residual and new bio class agricultural chemicals are carried out rationally composite, be an important research direction.Can reduce R&D costs significantly, shorten the R&D cycle, and practicality be stronger.I research staff of company is passing through long-term agriculture chemical compounding screening test research; After the demonstration; A kind of new pesticide sterilizing composite has been proposed; This bactericidal composition contains cyproconazole and two kinds of effective active components of chitin, and all the other prepare required complementary component for agricultural chemicals with the relevant auxiliary agent and the formulations of pesticide.
Composite with active ingredient cyproconazole and chitin as one of important technology characteristic of the present invention; Cyproconazole is a chemical pesticide efficient, low toxicity; Chitin is a kind of biopesticide that has the plant growth regulating function concurrently; All can produce synergistic effect but the such biopesticide of not all chemical pesticide and chitin is composite, like this simple inference.Every kind of chemical pesticide all has its unique chemical structure, and its unique physical and chemical properties characteristic is arranged.Can produce synergistic effect needs certain reasoning based on the chemical structural formula aspect, but more needs concrete experimental verification, concludes, and analyzes, and sums up.And the medicament of finding at present with plant adjusting activity is fewer; The chitin characteristic is very unique, and it can produce mould system by inducing plant, improves the plant disease-resistant ability; Guarantee the good harvest of plant high yield; Can promote the increase of profitable strains such as azotobacter spontaneous in the soil, lactic acid bacteria, cellulose-decomposing bacteria, actinomycetes, regulate useful mould activity in the soil, guarantee it and in good soil environment, grow.After the checkings through a large amount of experiments, we find to have a very strong compatibility with both are composite, can prepare a lot of agricultural chemicals common formulations, and have obvious synergistic effect, and compositely between not all agricultural chemicals all possess this point.
In the bactericidal composition of the present invention in addition; The proportioning of two kinds of active ingredients is that mass percent is similarly one of important technology characteristic of the present invention; Wherein the mass percent of effective active composition cyproconazole and chitin is 1～90: 20～0.1; All have synergistic effect, but its synergistic effect size there is a little difference.The later stage some among a small circle on the basis of the specific aim proportioning screening test of proportioning, can the mass percent of effective active composition cyproconazole and chitin in the bactericidal composition of the present invention be preferably 1～45: 10～0.1.
It is one of key character of the present invention that two kinds of effective active components of cyproconazole of the present invention and chitin are re-dubbed new compositions according to a certain percentage, and another feature is that described to contain the formulation that cyproconazole and the composite bactericidal composition of chitin can be made into be aqueous emulsion, aqua, suspending agent, suspension seed-coating agent, wetting powder, water dispersible granules.
Wherein according to the invention is two yuan of composite bactericidal compositions of active ingredient with cyproconazole and chitin, and it is 1%-90% that the gross mass of two kinds of effective active components accounts for total formulation gross mass percentage, preferred 3%-50%; All the other prepare complementary component for usual auxiliaries in the agricultural chemicals and formulation.
