Efficiencies of 5 Bio-fungicides Against Phytophthora Foot Rot Disease in Black Pepper
摘要
Abstract
Phytophthora foot rot disease is a destructive disease and responsible for severe economic losses in black pepper production throughout the world.In China,agrochemicals are often used to control the disease,which is negatively perceived by consumers and increasingly banned by governmental policies.The use of biofungicides to control diseases is an environment-friendly approach.The bio-control efficiencies of 5 bio-fungicides against Phytophthora foot rot disease were determined by the dural culture method on PDA plates and potted plant test in this study.Trichoderma WP,Bacillus subtilis WP and B.subtilis Z culture were found potent in the pathogen growth inhibition with the EC50 values of 0.49 μg/mL,0.78 μg/mL and 1.13 μg/mL,respectively.However,B.subtilis WP and B.subtilis Z culture exhibited excellent bio-control efficiencies (83% and 82% respectively),the after bio-fungicide,Paecilomyces lilacinus WP,showed an efficiency of 69%.In conclusion,B.subtilis WP and B.subtilis Z culture are potent bio-fungicides,their application might help in forming the green agriculture of black pepper.关键词
