Abstract
The invention relates to a bactericide composition with a synergistic effect. Effective active ingredients of the composition comprise cyproconazole and iprodione in a weight ratio of 10:1-1:60, and an aid and an excipient are added into the active ingredients to form wettable powder, water dispersible granules and suspensions. The bactericide composition is mainly used for preventing and controlling the botrytis, early blight, sclerotiniose and spot defoliation of crops.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of application of bactericidal composition on fruit diseases that contains cyproconazole and iprodione.
Technical background
Cyproconazole, (having another name called Cyproconazole) English name: Cyproconazole, molecular formula: C
15H
18ClN
3O, chemical name: 2-(4-chlorphenyl)-3-cyclopropyl-1-(1H-1,2,4-triazol-1-yl) fourth-2-alcohol.
Cyproconazole belongs to triazole bactericidal agent.Be sterol demethylation inhibitor, have prevention and therapeutic action.All effective to the Erysiphales on cereal crop, coffee, beet, fruit tree and the grape, Uredinales, the mould genus of genus spore, Rhynchosporium spp, Septoria, Venturia bacterium.Use with other bactericide, can fine cereal eye spot disease, leaf spot and the net blotch of preventing and treating.The control wheat rust lasting period was 4～6 weeks, and preventing and treating powdery mildew was 3～4 weeks.Cereal, fruit tree and grape powdery mildew, peanut, beet tops pinta, apple snow mildew and peanut white rot.
Iprodione (iprodione), molecular formula are C
13H
13Cl
2N
3O
3, chemical name: 3-(3, the 5-dichlorophenyl)-N-isopropyl-2,4-dioxo imidazoline-1-carboxylic acid amides.
Iprodione belongs to the agent of broad spectrum activity contact sterilization, and the Profilin kinases is controlled signal in the cell of many cell functions, comprises that carbohydrate is in conjunction with the interference effect that enters fungal cell's component.Therefore, it both can suppress fungus spore germination and generation, also can suppress mycelial growth.Can absorb therapeutic action by root.Bacterium such as Botrytis, neurospora, Sclerotinia, bulbil genus had bactericidal effect preferably.Bacterium such as Alternaria, the mould genus of the spore of wriggling, silk nuclear genus, Fusarium, volt leather genus are also produced effect.
No matter be cyproconazole, iprodione or other efficient germicides, long-term use separately makes disease develop immunity to drugs easily, causes the problem that dosage strengthens, preventive effect reduces, the lasting period shortens, and is unfavorable for environment sustainable development.The active ingredient of the different mechanisms of action is carried out composite, is to delay the disease method commonly used that develops immunity to drugs, and according to the effect in the production application, judge this composite be synergistic effect or antagonism.Complex role is more significantly filled a prescription, and can obviously improve preventive effect, reduces the dosage of agricultural chemicals greatly, also can enlarge fungicidal spectrum, improves germicidal efficiency.Cyproconazole is different with the iprodione mechanism of action, and mutually composite have good synergistic effect within the specific limits.And composite about cyproconazole and iprodione do not see relevant report at present at home and abroad as yet.
Summary of the invention
The objective of the invention is to propose a kind of have synergistic function, use cost is low, preventive effect the is good bactericidal composition that contains cyproconazole and iprodione.
The present invention is achieved through the following technical solutions:
A kind of bactericidal composition that contains cyproconazole and iprodione, wherein cyproconazole and iprodione weight ratio are 10: 1 to 1: 60.

Beneficial effect of the present invention: (1) present composition effective active composition cyproconazole and iprodione belong to the bactericide of two kinds of different mechanisms of action, and both are mixed mutually and can produce conflict; (2) present composition has good synergistic effect within the specific limits, and preventive effect is higher than single agent, and dosage is little; (3) the present invention not with an organic solvent is not difficult for producing poisoning, is convenient to transportation and storage; (4) present composition has special efficacy to the gray mold on the gourd, fruit and vegetable, early blight, stalk break, spot defoliation.
Embodiment
To further instruction of the present invention, the percentage among the embodiment all is weight percentage below in conjunction with embodiment, but the present invention is not limited thereto.
The embodiment of the invention is the method that adopts Toxicity Determination and field trial to combine.Pass through Toxicity Determination earlier, the synergy ratio (SR) after clear and definite two kinds of medicaments are composite by a certain percentage, SR＜0.5 is an antagonism, and 0.5≤SR≤1.5 are summation action, and SR＞1.5 are synergistic effect, on this basis, carry out field trial again.
Implementation of an application example one:
Cyproconazole and iprodione are to the stem rot of cucumber Toxicity Determination
Test medicine provides by Shaanxi agricultural chemicals Co., Ltd of U.S. nation.
After the effective inhibition concentration scope of each medicament was determined in prerun, each medicament was established 7 dosage respectively by active constituent content and is handled, and established the clear water contrast.Carry out with reference to " agricultural chemicals indoor bioassay test rule bactericide ", adopt the mycelial growth rate method to measure the virulence of medicament stem rot of cucumber.Measure colony diameter with the right-angled intersection method behind the 72h, calculate and respectively handle clean amount of growth, mycelial growth inhibition rate.
Clean amount of growth (mm)=measurement colony diameter-5
Mycelial growth inhibition rate is converted into probit value (y), and liquor strength (μ g/mL) converts logarithm value (x) to, tries to achieve virulence regression equation (y=a+bx) with method of least squares, and calculates the EC of every kind of medicament thus
50Value.Calculate the different proportioning synergy ratios (SR) of two medicaments according to the Wadley method simultaneously, SR＜0.5 is an antagonism, and 0.5≤SR≤1.5 are summation action, and SR＞1.5 are synergistic effect.Computing formula is as follows:
Wherein: a, b are respectively cyproconazole and iprodione shared ratio in combination
A is a cyproconazole
B is an iprodione
Result of the test is as shown in table 1:
Table 1 cyproconazole, iprodione and composite toxicity test analysis of results table thereof to stem rot of cucumber
As shown in Table 1, cyproconazole, iprodione are to the EC of stem rot of cucumber
50Be respectively 2.93mg/L and 18.35mg/L.The virulence of cyproconazole is apparently higher than the virulence of iprodione.Cyproconazole and iprodione were mixed in the scope at 10: 1～1: 60 and all show obvious synergistic effect.Wherein, both mixed synergies in 1: 1～1: 30 scope are particularly outstanding.
