Abstract
Yellow disease is a complex disease caused by
Fusarium sp., Phytophthora sp., and nematodes. Infected
plants were quickly killed and were difficult for replanting,
causing significant losses for the growers. Various control
methods were examined including the use of bioconrol
agents and cover crop Arachis pintoi. The research
objective was to determine the ability of biocontrol agents
and A. pintoi to improve pepper growth and reduce yellow
disease incidence on pepper plants in the field. Research
results showed that the treatment of biocontrol and
A. pintoi promoted vegetative growth of pepper plants, and
increased pepper height for up to more five times, and
reduced yellow disease incidence to 30%
Abstrak
Penyakit kuning merupakan penyakit kompleks yang
disebabkan oleh Fusarium sp., Phytophthora sp. dan
nematoda parasit. Tanaman sakit mengalami kematian
yang cepat dan kebun yang telah terinfeksi sulit untuk
ditanami kembali, sehingga mengakibatkan kerugian yang
nyata terhadap petani. Berbagai cara pengendalian telah
diuji termasuk penggunaan agens hayati Plant Growth
Promoting Rhizobacteria (PGPR), Trichoderma sp. dan
tanaman Arachis pintoi. Tujuan penelitian adalah
mengetahui kemampuan agensia hayati dan Arachis pintoi
dalam meningkatkan pertumbuhan dan mengurangi
kejadian penyakit kuning pada tanaman lada di lapang.
Hasil penelitian menunjukkan bahwa perlakuan agens
hayati dan A. pintoi meningkatkan tinggi dan jumlah daun
tanaman lada lebih dari lima kali serta mempercepat
munculnya sulur dibandingkan dengan kontrol dan
fungisida. Aplikasi Trichoderma sp. yang dikombinasi
dengan A. pintoi menekan kejadian penyakit kuning hampir
30%.
