Acaricidal activity of Fusarium subglutinans 12A on Tetranychus urticae Koch (Acari: Tetranychidae

In this study, efficacy of different spore concentrations of fusarium subglutinans 12a isolate on tetranychus urticae koch females was investigated. the experimental design was a complete randomized block and all trials were conducted in five replications. in the study, 1x10^4, 1x10^6 and 1x10^8 spores/ml spore concentrations were applied to shell bean leaves that were prepared according to leaf disc method spraying in droplets at 1 atm pressure. observations on mortality of females and also mycosis developing on dead individuals were conducted on the 3rd, 5th, and 7th days after application. according to the study results, mortality rates were higher than control at three spore concentrations, but they did not differ from each other (f 44,239; df 3; p> 0.05). mycosis were not significant at three spore concentrations (f 2,387; df 2; p> 0.05). moreover, it was determined that the time-dependent mortality rate after application of fusarium subglutinans 12a isolate was the highest on the 7th day at all spore concentrations.
