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 nitrile bacterium azoles that contain.
Technical background
Pressing down mould azoles (imazalil) is triazole bactericidal agent.Molecular formula is C
14H
14Cl
2N
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 it is excellent to the control efficiency of powdery mildew and anthracnose on melon and fruit, the vegetables to find to press down mould azoles in the last few years.
Nitrile bacterium azoles (myclobutanil) is an azoles fungicide.Molecular formula is C
15H
17ClN
4, the own nitrile of chemical name: 2-(4-chlorphenyl)-2-(1H, 1,2,4-triazole-1-methyl).
Nitrile bacterium azoles is one type of triazole bactericidal agent with protection and therapeutic activity.This medicine mainly plays inhibitory action to the biosynthesis of the ergosterol of pathogen, causes cell membrane not form, and makes germ dead.Gammaproteobacteria, Basidiomycetes all have the better prevention effect in the antithetical phrase.This medicament lasting period is long, to crop safety, certain stimulating growth effect is arranged.
No matter be to press down mould azoles, nitrile bacterium azoles 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 different effects mechanism 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 nitrile bacterium azoles 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 nitrile bacterium azoles.

Practice example two: press down mould azoles and myclobutanil compositional to the powdery mildew of cucumber Toxicity Determination
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 confirmed 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 following:
Wherein: a, b are respectively and press down mould azoles and nitrile bacterium azoles shared ratio in combination
A is for pressing down mould azoles
B is a nitrile bacterium azoles
Result of the test is as shown in table 1:
Table 1 presses down mould azoles, nitrile bacterium azoles and composite toxicity test analysis of results table to powdery mildew of cucumber thereof
Can know by table 1, press down mould azoles, nitrile bacterium azoles EC powdery mildew of cucumber
