Abstract
The invention relates to a cyprodinil and propineb-containing sterilizing composition, the weight ratio of the active ingredients of the cyprodinil and the propineb is 5-80:80-5; and added with an auxiliary agent and an excipient, the effective active components can be prepared into wettable powder, water dispersible granules and suspending agent. The sterilizing composition is used for preventing and controlling diseases on fruit trees and cereals and has obvious synergism on the prevention and treatment of gray mold, alternaria leaf spot, peronospora tabacina and anthracnose of crops.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of contain cyprodinil and the composite application of bactericidal composition on fruit tree and vegetable disease of Propineb.
Technical background
Cyprodinil (cyprodinil) is that pure product are powdery solid by the aminopyrimidine bactericide of Syngenta Co.,Ltd's exploitation.Molecular formula: C
14H
15N
3, chemical name: 4-cyclopropyl-6-methyl-N-phenyl pyrimidine-2-amine.
Cyprodinil is the methionine biosynthesis inhibitor.No cross resistances such as same triazole type, imidazoles, morpholine class, phenylpyrrole class.The main mode of action of cyprodinil is to suppress the biosynthesis of methionine moral, suppresses the secretion of hydrolase.Absorbed rapidly by blade in plant corpus, be penetrated into more than 30% in the tissue, protected sediment is stored in the blade; transmit in xylem, also transmit between blade, metabolism at high temperature is rapid relatively; sediment quite stable under the low temperature in blade, metabolite inanimate object activity.Be mainly used in the gray mold, powdery mildew, scab of control wheat, barley, grape, strawberry, fruit tree, vegetables, ornamental plants etc. etc.
Propineb (propineb), molecular formula: (C
5H
8N
2S
4Zn)
x, chemical name: acrylic bisdithiocarbamic zinc.
Propineb is a kind of protective fungicide of quick-acting, long residual, wide spectrum, and its bactericidal mechanism is fixing, and site of action is many, mainly suppresses the oxidation of pyruvic acid in the cause of disease thalline.Downy mildew of crops such as vegetables, grape, tobacco and morning, the late blight of tomato and potato all there are good protective effect, and the disease of powdery mildew, rust and Botrytis is also had fixed inhibitory action.As alternaria leaf spot of apple, Chinese cabbage downy mildew, cucumber downy mildew, downy mildew of garpe, early blight of tomato and late blight, target and late blight, mango anthracnose, Alternaria alternate.
In the real process of agricultural production, preventing and treating the problem that disease is easy to generate most is the drug-fast generation of germ.Important disease such as gray mold, spot defoliation, leaf spot etc. are because its spread speed is fast on the agricultural, and host range is wide, often takes place in the plant growth later stage, is easy to generate resistance especially.In some diseases serious place takes place, use such as common bactericide such as tpn, thiophanate-methyl, tmtd, Propineb etc. have separately caused very serious resistance, and cyprodinil etc. can large tracts of land use because of the higher portion of price.At present, adopt composite bactericidal composition can obviously improve control and result of treatment, reduced the usage amount of agricultural chemicals, reduced cost, become the important means of the various diseases of integrated control.
So far do not see the relevant report of relevant cyprodinil and the composite product of Propineb on domestic and international magazine and the related media as yet.
Summary of the invention
The purpose of this invention is to provide the bactericidal composition that contains cyprodinil and Propineb that a kind of antagonism germ has synergistic effect.
The present invention is achieved through the following technical solutions:
The bactericidal composition that contains cyprodinil and Propineb, cyprodinil and Propineb percentage by weight are 5～80: 80～5, percentage by weight after wherein preferred is 10～60: 70～10, preferred percentage by weight is 20～50: 60～20, effective active composition weight percentage is 10% to 80%, adds auxiliary agent and excipients and makes wetting powder, water dispersible granules, suspending agent.
When making wetting powder, composition comprises following constituent content: cyprodinil 5～80%, Propineb 5～80%, dispersant 3～15%, wetting agent 2～12%, filler 5～84%.
Cyprodinil, Propineb, dispersant, wetting agent, filler are mixed in mixed cylinder, after airslide disintegrating mill is pulverized, mix again, promptly can be made into the cyprodinil Wettable propineb powder.
When making water dispersible granules, composition comprises following constituent content: cyprodinil 5～80%, Propineb 5～80%, dispersant 3～12%, wetting agent 2～8%, disintegrant 0～8%, filler 5～84%.
Cyprodinil, Propineb, dispersant, wetting agent, disintegrant, filler etc. are obtained the particle diameter that needs through comminution by gas stream together, obtain the materials of granulating.It is interior through after granulation and the drying to expect that product are quantitatively sent the fluidized bed granulation dryer to, makes cyprodinil Propineb water dispersible granules product.
When making suspending agent, composition comprises following constituent content: cyprodinil 5～50%, Propineb 5～50%, dispersant 3～12%, wetting agent 2～10%, emulsifier 1～6%, defoamer 0.1～0.5%, thickener 0～2%, antifreeze 0～8%, deionized water surplus.
Dispersant, wetting agent, defoamer, thickener, antifreeze in the above-mentioned formulation material are mixed through high speed shear, add cyprodinil, Propineb, ball milling is 2～3 hours in ball mill, makes diameter of particle all below 5 μ m, makes cyprodinil Propineb suspending agent product.
Described dispersant, wetting agent, emulsifier, disintegrant, defoamer, thickener, antifreeze, filler are the conventional auxiliary agent in present technique field.
Described bactericidal composition is used to prevent and treat the disease on fruit tree and the cereal, is mainly used in to prevent and treat gray mold, spot defoliation, downy mildew, anthracnose.
The invention has the advantages that: (1) cyprodinil has the different mechanisms of action with Propineb, mutual composite no antagonism; The agricultural chemicals of (2) two kinds of different mechanisms of action carries out composite, has both enlarged fungicidal spectrum, has saved production cost again; (3) composition does not contain organic solvent, and environmental pollution is little, and use cost is low; (4) be used to prevent and treat gray mold, spot defoliation, downy mildew, anthracnose and have good synergistic effect.
