Perbandingan Efektivitas Formulasi Biopestisida FOBIO dengan Fungisida Kimia dalam Mengendalikan Penyakit Layu Fusarium pada Tanaman Melon

Abstract

Fusarium wilt caused by Fusarium oxysporum f. sp. melonis is a major constraint in melon cultivation due to its rapid progression and impact on plant productivity. This study aimed to evaluate the performance of different biopesticide concentrations of FOBIO, functioning as a potential PGPR-based biological agent, compared with the chemical fungicide mancozeb in suppressing disease development and enhancing plant growth and yield. The experiment was arranged in a Randomized Complete Block Design with four treatments: biopesticide concentration of FOBIO at 7.5 mL/L, biopesticide concentration of FOBIO at 10 mL/L, mancozeb at 2 g/L, and an untreated control. FOBIO at 10 mL/L extended the incubation period to 62.33 days after transplanting, reduced disease incidence to 15.55%, and achieved the highest control efficacy of 63.16%. This concentration also resulted in the highest vegetative growth. Overall, the biopesticide concentration of FOBIO at 10 mL/L demonstrated superior effectiveness in mitigating Fusarium wilt and improving melon yield and fruit quality..
