摘　　要：Fusarium species(including Fusarium anthophilum)have many insidious effects on mankind,animals,and plants.Their attack may lead to diseases or spoilage,and the production of mycotoxins.This study was conduct­ed to find solutions to the infections by F.anthophilum.Three sub-trials(botanical,chemical and biocontrol sub-trials)were set up using completely randomized design,and each treatment was replicated thrice.The percent­age inhibition of F.anthophilum in the botanicals-alone subtrial(i.e.,Eu­calyptus,Euphorbia,Andrographis,and Melaleuca spp.)at 50%and 100%concentrations ranged from 20%to 100%.At 72,120,and 168 HAI(hours after inoculation),Eucalyptus(all concentrations)controlled the pathogen significantly more,followed by Melaleuca(all concentrations).All the bo­tanicals(at both concentrations)controlled Fusarium sp.significantly more compared to the control.Based on the second sub-trial:the best synthetic fungicide+Trichoderma harzianum treatment was Mancozeb100%,and the percentage inhibition by these combined chemical+biocontrol treatments ranged from 28%to 50%.Mancozeb100%,followed by Metalaxyl+Cu(I)O 100%produced the highest inhibition.All chemical treatments were sig­nificantly different compared to the control(120 hours after inoculation).Based on the third subtrial:the best Botanical+T.harzianum treatment was Alligator pepper100%followed by Tumeric100%.The percentage inhibition of Fusarium sp.by these treatments ranged from 28%to 70%.Alligator pepper100%followed by Tumeric100%,then Tumeric50%,and Eucalyptus100%…were significantly different compared to the control.Combining different agents was effective in controlling the pathogen.However,lower percentage inhibitions were obtained.More research on integrating the control agents is being admonished.
