The Effect of Some Biological Fungicides and Liquid Organic Fertilizers on Sigatoka Disease on ‘Mas’ Banana Plants (Musa acuminata Colla)

potential and export prospects. According to the Directorate General
of Horticulture, Ministry of Agriculture, banana production from 2009
to 2014 fluctuated due to attacks by Plant Destruction Organisms
(PDO), particularly Sigatoka disease caused by the fungus
Mycosphaerella musciola. This study investigated biological agents
like Trichoderma sp. and Gliocladium sp., along with liquid organic
fertilizers, to control the disease without synthetic fungicides.The
research, conducted at the University of Muhammadiyah Malang,
used a split-plot design with two factors: biological pesticides
(Tricogreen, Natural Glio, Trico-G) and liquid organic fertilizers (rabbit
urine POC, shrimp shell MOL, banana hump MOL). The experiment
had nine treatment combinations with three plant samples each.
Results showed that biological pesticides significantly reduced
Sigatoka disease intensity, with the J3P3 treatment (Trico-G and
Banana Hump MOL) achieving the lowest infection rate of 29.55%,
reducing disease intensity by 70.45%. Liquid organic fertilizers also
improved plant growth, increasing leaf number and leaf area. This
indicates that biological agents and organic fertilizers effectively
manage Sigatoka disease and promote healthy banana plant growth.
