Potency of entomopathogen Beauveria bassiana fungus as biofertilizer and biostimulant to increase the plant growth of Cayenne pepper (Capsicum frutescens L.)

Abstract This research aimed to determine the Beauveria bassiana entomopathogen fungus as a biofertilizer and biostimulant. The was conducted at Biological Control laboratory Wire House, Universitas Andalas. potency of B. produced IAA hormone carried out by qualitative observing pink color change in Salkowsky solution while dissolve phosphate using Pikovskaya medium. test results on media showed that all tested isolates had potential 7, 10, 14 days. largest clear zone area days, found Bb WS (5.42 mm) followed TD312 (5.28mm). To plant growth testing germination seeds blotter paper. design used non-factorial Completely Randomized. highest percentage BbWS isolates. promoters can be seen from an increase height number chili leaves. All indicated applied biological fertilizers biostimulants cayenne pepper plants.
