Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of contain cyprodinil with and the bactericidal composition of antibiotics compound jinggangmeisu or kasugarnycin.
Technical background
Cyprodinil, English name: cyprodinil, molecular formula: C

Kasugarnycin is an agricultural antibiotic, has stronger interior absorption, and this medicine mainly disturbs amino acid whose metabolism esterase system, thereby influences the synthetic of protein, suppresses the mycelia elongation and causes cell granulationsization, but spore germination is not had influence.
No matter be cyprodinil, jinggangmeisu (kasugarnycin) 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.And a kind ofly do not have the novel pesticide of cross resistance to prevent and treat pathogen if want newly developed, and then need screen 10,000～1.5 ten thousand compounds, expensive 1～1.5 hundred million dollar, the construction cycle is 6～10 years.And that the active ingredient of the different mechanisms of action is carried out is 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.
Cyprodinil is different with jinggangmeisu (kasugarnycin) mechanism of action, and mutually composite have good synergistic effect within the specific limits.And composite about cyprodinil and jinggangmeisu (kasugarnycin) do not see relevant report at present at home and abroad as yet.
Summary of the invention

Embodiment
To further instruction of the present invention, but the present invention is not limited thereto below in conjunction with embodiment.Percentage in following examples all is weight percentage.
The embodiment of the invention is the method that adopts Toxicity Determination and field trial to combine.
Implementation of an application example one: cyprodinil and jinggangmeisu (or kasugarnycin) are composite to the rice blast Toxicity Determination
After the effective inhibition concentration scope of each medicament was determined in prerun, each medicament was established 5 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 rice blast.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 cyprodinil and jinggangmeisu (or kasugarnycin) shared ratio in combination
A is a cyprodinil
B is jinggangmeisu (or kasugarnycin)
Result of the test is as shown in the table:
Table 1 cyprodinil, jinggangmeisu and composite toxicity test analysis of results table thereof to rice blast
As shown in Table 1, cyprodinil, jinggangmeisu are to the EC of rice blast
50Be respectively 3.48mg/L and 39.36mg/L.The virulence of cyprodinil is higher than the virulence of jinggangmeisu.The virulence of cyprodinil is apparently higher than the virulence of jinggangmeisu.Cyprodinil and jinggangmeisu were mixed in the scope at 1: 1～1: 64 and all show obvious synergistic effect.Wherein, both mixed synergies in 1: 2～1: 16 scope are comparatively desirable, and mixed synergies is particularly outstanding in 1: 2～1: 8 scope.
Table 2 cyprodinil, kasugarnycin and composite toxicity test analysis of results table thereof to rice blast
As shown in Table 2, cyprodinil, kasugarnycin are to the EC of rice blast
50Be respectively 5.46mg/L and 0.17mg/L.The virulence of cyprodinil is higher than the virulence of kasugarnycin.Cyprodinil and kasugarnycin were mixed in the scope at 1: 1～1: 64 and all show obvious synergistic effect.Wherein, both mixed synergies in 1: 2～1: 32 scope are comparatively desirable, and mixed synergies is particularly outstanding in 1: 2～1: 16 scope.
