Research on the Prevention and Control Measures of Eucalyptus Cylindrocladium Quinqueseptatum
In order to investigate the control effects of different fungicides on Eucalyptus robusta Smith Cylindrocladium quinqueseptatum,this paper takes Nanning region of Guangxi as the experimental site and investigates different wettable powders.Reagent 1:carbendazim(50%wettable powder);Reagent 2:Daisenzin(65%wettable powder);Reagent 3:methyltobuzin(70%wettable powder),and Reagent 4:The prevention and control effect of metalaxyl manganese zinc(72%wettable powder)on Eucalyptus Cylindrocladium quinqueseptatum at different dilution ratios(250 times,500 times,1000 times)and different post treatment times(5 days,10 days,15 days,etc.).The results show that as the dilution ra-tio of the drug increases and the increased treatment time,the prevention and control effect will signifi-cantly decrease.Among different application conditions,metalaxyl manganese zinc(250 times)had the highest control effect on the 5th day after application,and under this experimental condition,the control effect of Eucalyptus Cylindrocladium quinqueseptatum was 87.28%.This paper provides a theoretical basis for Eucalyptus cultivation.
