Abstract

Pseudomonas fluorescens (Pf) known as biological control agent for yellow curl virus in chili. Another biocontrol agent, Beauveria bassiana (Bb) could control many  pest as thrips, myzus, and caterpillar. This report describe the effectivity of Pseudomonas fluorescens and also Beauveria bassiana to control pest and disseases in chili. The research was carried out on field  of 1000 m, at Gandurejo Village, Bulu District, Temanggung Regency. Pseudomonas fluorescens applied on chili plant 6 (six) times, started at 1 week after planting with interval 1 week per application. Beauveria bassiana applied 3 (three) days after the Pseudomonas. Water was applied on Control area, at the same time as Pseudomonas application. Observations were carried out on 30 sample units each week.

The parameter were plant height, diameter of plant canopy, intensity of plant pest and disease attack, and production of the chili. Result showed that applied of  Pf and Bb significantly affected the height of plant, diameter of plant canopy, and also effectively inhibited caterpillar attack and yellow curl virus with 31,05% inhibited. However, although the application didn’t show any significant effect on yield it could decrease cost significantly. and also reduce synthetic pesticide usage, which support environment friendly agriculture.
