Aplikasi Pupuk Hayati Dan Beauveria Bassiana Vuillemin Lokal Terhadap Pertumbuhan, Ketahanan Dan Produksi Tanaman Padi (Oryza Sativa L.)
ABSTRACT
Red chili plant (Capsicum annum L.) is a horticultural plant that has high economic value in Indonesia. Pest attacks on red chili plants are an obstacle in the cultivation of red chili. Armyworm caterpillars (Spodoptera litura F.) are pests of red chili plants that can cause yields to decrease up to 80%. The control using local entomopathogenic fungi Beauveria bassiana is an effort to control S. litura using environmentally friendly materials. This research aims to obtain local concentrations of B. bassiana which can control S. litura in red chili plants. The research was conducted at the Plant Pest Laboratory and Experimental Garden, Faculty of Agriculture, Riau University from July to August 2020. The research was designed a completely randomized design with five treatments are concentration of local B. bassiana 20 g.l-1 water, 25 g.l-1 water, 30 g.l-1 water, 35 g.l-1 water and 40 g.l-1 water and four replications in order to obtain 20 experimental units. The results showed that the concentration of B. bassiana local 30 g.l-1 of water contains a conidia density of 4.1 × 108 con.ml-1 is a was able concentration as bioinsecticide of controlling the S. litura pest on red chili plants with a total mortality of 77.5%, the initial time of death was 48 hours after application and the lethal time was 50 with 83 hours after application.
Key words: Biopesticide, Capsicum annum, Beauveria bassiana, Spodoptera litura, local entomopathogenic fungi.
