Pesticidal combination of the present invention can be prevented and treated multiple citrus disease, for example, rubber disease, anthracnose, blister mite, two spotted spider mite, leaf miner etc., concrete, now enumerate this composition to experimentation and the result of the Toxicity Determination of oranges and tangerines resin disease (broken skin disease) and citrus red mite, please refer to following content:
1, composition of the present invention is to the Toxicity Determination of oranges and tangerines resin disease (broken skin disease):
The mycelial growth rate method is adopted in test, getting experiment soup that 5ml prepares joins the hot medium of 45ml (PDA medium is housed, 45-50 ℃) conical flask in, after shaking up, pour diameter 90mm glass culture dish rapidly into, each culture dish is poured band medicine medium 12ml into, and each handles 4 repetitions, level leaves standstill, cooling back flat board.Cut bacterium cake from what cultivate 4d for examination bacterium edge with diameter 5mm card punch, receive and be with on the malicious medium with choosing one side that pin will have a mycelia, all operations all carries out sterile working at superclean bench.After the processing flat board is placed on and adopts the right-angled intersection method to measure the colony diameter that each is handled respectively after cultivating 4d in 20 ℃ the constant temperature aseptic culture case, calculate the mean value of respectively handling colony diameter, average clean amount of growth and the mycelial growth inhibition rate of colony diameter.
The clean amount of growth of bacterium colony (mm)=colony diameter-5
Mycelial growth inhibition rate (%)=((the clean amount of growth of the contrast bacterium colony-clean amount of growth of processing bacterium colony)/clean amount of growth of contrast bacterium colony) * 100
Concentration conversion is become the natural logrithm value, and inhibiting rate conversion arcsin function value is dependent variable with arcsine letter replacement value, be independent variable with dosage natural logrithm value, carry out linear regression analysis with the DPS Biological Statistic Analysis Software, draw regression equation, carry out anti-natural logrithm conversion again and draw EC50; Calculate toxicity index and the co-toxicity coefficient (CTC) of medicament according to the abundant method of Sun Yun.
Actual measurement toxicity index=standard medicament EC50/ reagent agent EC50 * 100; The theoretical toxicity index of the single agent=single agent actual measurement toxicity index * content of single agent in mixture; The theoretical toxicity index of the mixture=theoretical toxicity index sum of each single agent; The theoretical toxicity index of toxicity index/mixture * 100 of co-toxicity coefficient=mixture actual measurement; Evaluation criterion: CTC≤80 are antagonism, and 80<CTC<120 are summation action, and CTC 〉=120 are synergistic effect, and experimental result please refer to table 6;
