Epidemiologi Penyakit Layu Bakteri dan Perkembangan Kompleks Spesies Ralstonia solanacearum

Andree Wijaya Setiawan


Layu bakteri merupakan salah satu penyakit terpenting karena sulitnya pengendalian serta pengaruhnya terhadap produksi banyak tanaman bernilai ekonomi di seluruh dunia. Bakteri Ralstonia solanacearum lebih dikenal dengan sebutan kompleks spesies Ralstonia solanacearum memiliki kisaran tanaman inang yang sangat luas. Tanaman tersebut meliputi lebih dari 400 spesies tanaman dari 50 famili tanaman penting yang dibudidayakan di Indonesia seperti kentang, tomat, terong, tembakau, cengkih dan pisang. Ulasan ini membahas epidemiologi penyakit yang disebabkan oleh R. solanacearum, perkembangan kompleks spesies R. solanacearum, dan mekanisme tindakan dalam manajemen penyakit berdasarkan metode kimia, biologi, budidaya dan fisik.


Kata kunci: Layu bakteri; Ralstonia solanacearum; epidemiologi; kompleks spesies; manajemen penyakit.
