INNOVATION OF MAIN PEST AND DISEASE CONTROL TECHNOLOGY USING BIOPESTICIDES ON SOYBEAN(GLYCINE MAX L.)

Abstract

The use of biopesticides is a control technology that can reduce the occurrence of resistanceand resurgence. The objective of the study was to determine the efficacy of Proposed technology (biopesticides) and Conventional technologies (synthetic pesticides) on soybean varieties. The study was conducted in an endemic location in Banyuwangi Regency, East Java Province, Indonesia, from April to September 2018. The results showed that the Proposed technology was able to suppress the development of stem rot disease (Sclerotium rolfsii) and blight (Rhizoctonia solani) by 54.18% and 47.84% in Martoloyo and Anjasmoro varieties, respectively, compared with Conventional technology. The Conventional technology was less effective in suppressing the development of rust disease (Phakopsora pachyrhizi), especially of Martoloyo and Anjasmoro varieties when compared to other varieties. The highest pest population occurred in the Proposed technology, namely the whitefly Bemisia tabaci followed by the leafminer Liriomyza sp. Predatory arthropods at the proposed technology obtained 13 species and nine types of parasitoids; both types of arthropods are potential as natural enemies but the population was very low at the conventional technology. Proposed technology has better prospects because it is eco-friendly, can suppress the occurrence of resistance and resurgence in endemic lands, and has no chemical pesticide residues.
