Abstract
The invention relates to a synergisitic bactericidal composition containing imazalil and flusilazole. The active ingredients of the bactericidal composition comprise the imazalil and the flusilazole, wherein the weight ratio of the imazalil to the flusilazole is 5-80:40-1. The active ingredients are added with an aid and an excipient to prepare wet powder, water dispersible granules, a suspending agent, and emulsion in water or microemulsion. The bactericidal composition is mainly used for preventing and controlling powdery mildew, anthracnose, cladosporium cucumerinum and downy mildew.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of application of bactericidal composition on crop pest that presses down mould azoles and Flusilazole that contain.
Technical background
Pressing down mould azoles (imazalil) is triazole bactericidal agent.Molecular formula is C

2O, chemical name: 1-{2-(2,4 dichloro benzene base)-2-(2-propenyloxy group) ethyl }-the 1H-imidazoles.
Pressing down mould azoles is a kind of interior absorption wide-spectrum bactericide, and the mechanism of action is to influence cell permeability of the membrane, physiological function and lipid anabolism, thereby destroys the cell membrane of mould, the formation of mould fungus inhibition spore simultaneously.Usually as seed treatment, or oranges and tangerines volume, banana and other fruit sprayed or the fruit that floods after being used to prevent to gather in the crops rots.But found to press down the control efficiency excellence of mould azoles in the last few years to powdery mildew and anthracnose on melon and fruit, the vegetables.
Flusilazole (flusilazole) is the miazines bactericide.Molecular formula is C

3Si, chemical name: two (4-fluorophenyl) methyl (1H-1,2, the support of 4-triazol-1-yl methylene) silane.
Flusilazole belongs to triazole bactericidal agent, and this medicine mainly is the biosynthesis that destroys and stop the cell membrane important composition composition ergosterol of germ, causes cell membrane not form, and makes germ death.In the antithetical phrase due to the germ of Gammaproteobacteria, Basidiomycetes and Fungi Imperfecti disease effective, invalid to oomycetes.
No matter be to press down mould azoles, Flusilazole 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.It is different with the Flusilazole mechanism of action to press down mould azoles, and mutual composite have good synergistic effect within the specific limits.And, do not see relevant report at present at home and abroad as yet about pressing down the composite of mould azoles and Flusilazole.

Implementation of an application example two: it is composite to the powdery mildew of cucumber Toxicity Determination to press down mould azoles and Flusilazole
Test medicine provides by Shaanxi means of agricultural production trade Co., Ltd of U.S. nation.
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 powdery mildew 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 (mg/L) 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 and press down mould azoles and Flusilazole shared ratio in combination
A is for pressing down mould azoles
B is a Flusilazole
Result of the test is as shown in table 1:
Table 1 presses down mould azoles, Flusilazole and composite toxicity test analysis of results table to powdery mildew of cucumber thereof
As shown in Table 1, press down mould azoles, Flusilazole EC to powdery mildew of cucumber
50Be respectively 28.53mg/L and 0.97mg/L.The virulence that presses down mould azoles is lower than the virulence of Flusilazole.Press down mould azoles and 10: 1,6: 1,2: 1,1: 2,1: 6 synergy ratio of Flusilazole proportioning and be respectively 1.58,1.74,2.15,1.88,1.61, illustrate that pressing down mould azoles and Flusilazole was mixed in the scope at 10: 1 to 1: 6 and all shows obvious synergistic effect, synergy ratio SR maximum when pressing down mould azoles and Flusilazole weight ratio and be 2: 1 wherein, synergistic effect is the most obvious.
