Abstract

The study aimed to determine the effect of Beauveria bassiana inoculation on the distribution of endophytic B. bassiana fungus colonization on plants, salicylic acid content, and population of B. tabaci insects on chili plants. The fungal isolates used were endophytic fungi from wheat (TD312), cacao (KT211), coffee plants (APKo), and entomopathogenic fungi from the insect Nilaparvata oratorius (BbWS). The inoculation technique was carried out by soaking the chili seeds for 6 (six) hours. The research was conducted at the Biological Control Laboratory and Wire House, Faculty of Agriculture, Andalas University from June to October 2021. The design used was a completely randomized design. Observation variables included the distribution of B. bassiana fungus colonization on the roots, stems, and leaves of chili peppers. analyzed the content of salicylic acid and observed the population of Bemisia tabaci on plants aged 7 to 63 days after transplanting. The results showed that all tested B. bassiana isolates were able to colonize the roots, stems, and leaves of chili peppers. The TD312 isolate produced the highest endophytic colonization and was found in leaves (53.33%), the lowest B. tabaci population was obtained from the treatment of B.bassiana BbWS isolates (9.00%). The highest content of salicylic acid was found in isolate TD312 at 15,427 ppm and the lowest was in the treatment of BbWS isolate at 9.298 ppm and control at 6.62 ppm. The overall results showed that inoculation of the endophytic entomopathogenic B. bassiana fungus was able to colonize plants and increase the salicylic acid content of chili plants and affect the population of B. tabaci.
