Description
Technical field
The invention belongs to technical field of pesticide, it relates to the application in a kind of fungicidal composition disease containing fenamidone and thiocarbamates.
Technical background
Fenamidone (fenamidone) molecular formula: C17H17N3OS, chemical name: (S)-1-anilino-4-methyl-2-methylthio group-4-benzylimidazoline-5-ketone, fenamidone is similar with the mechanism of action of Famoxate and methoxy acrylic bactericide, suppressing line runic to breathe by stating blocks electrons transfer in former side of body level at hydrogenation olive ferment Q mono-cytochrome C radon, imidazoles bacterium cave (s)-enantiomorph specific activity (R)-enantiomorph is much higher.
Zinc manganese ethylenebisdithiocarbamate (Mancozeb) chemical name: the complex salt of the two dithio carbamyl manganese of ethylene and zinc. The protectiveness sterilant that fungicidal spectrum is wider. Mainly suppress the oxidation of pyruvic acid in thalline. The multiple diseases such as the anthrax on fruit tree, vegetables, early blight is effective, and its normal and systemic fungicide mixture simultaneously, for the generation of delaying drug resistance.
Carbatene (Metiram) chemical name: two (the two sulphur carbamates) zinc (2+) of three [ammonia] ethene)] [tetrahydrochysene-1,4,7-two thiophene diazocine-3,8-connects dithione], polymer. Protectiveness sterilant, belongs to low-toxin farm chemicals, and the very microbial various disease of Oomycete is had good anti-effect.
Zineb (Zineb) chemical name: zinc ethylenebisdithiocarbamate. Zineb is the protective material that a kind of foliage spray uses, to many germs as Pseudoperonospora cubensis, late disease bacteria and anthrax bacteria etc. have stronger action of contace poison. To plant safety, effective constituent chemical property is more active, water is easily oxidized to different thiocyanation compound, the enzyme that cause of disease thalline includes-SH base has strong restraining effect, and can directly kill germ spore, suppress the germination of spore, stop in germ invaded plants body, but the lethal effect of the cause of disease mycelium in invaded plants body is very little. Therefore, it may also be useful to zineb controlling disease should rest in disease to be begun to see that the phase carries out, and could obtain good effect. The drug effect phase of zineb is short, decomposes very fast, about 7 days its residual effect phases after the moisture in sun exposure and absorption air.

The embodiment of the present invention is the method adopting Toxicity Determination and field test to combine. First by Toxicity Determination, the synergy ratio (SR) after clear and definite two kinds of medicaments are composite by a certain percentage, SR < 0.5 is antagonistic action, 0.5��SR��1.5 are summation action, SR > 1.5 is synergism, on this basis, then carries out field test.
Test method: determine after the effective inhibition concentration scope of each medicament through prerun, medicament establishes 5 dosage process respectively by active constituent content, if clear water comparison. Carry out with reference to " farm-chemical indoor determination test rule sterilant ", adopt mycelial growth rate method to measure medicament to the virulence of crop germ. Measure colony diameter with cross interior extrapolation after 72h, calculate each process net growth, mycelial growth inhibition rate.
Net growth (mm)=measurement colony diameter-5
Mycelial growth inhibition rate is converted into probit value (y), and liquor strength (�� g/mL) converts logarithmic value to (x), tries to achieve virulence regression equation (y=a+bx) with method of least squares, and thus calculates the EC of often kind of medicament50Value. Calculating two medicaments different ratio synergy ratio (SR) according to Wadley method, SR < 0.5 is antagonistic action, and 0.5��SR��1.5 are summation action simultaneously, and SR > 1.5 is synergism. Calculation formula is as follows:
Wherein: a, b are respectively active components A and activeconstituents B ratio shared in combination;
A is fenamidone;
The one that B is selected from zinc manganese ethylenebisdithiocarbamate, Carbatene, zineb, zinc 1,2-propylene bisdithiocarbamate.
