Antagonisme jamur rizosfer tanaman karet terhadap Rigidoporus microporus secara in vitro dan in planta
Penyakit jamur akar putih (JAP) yang disebabkan oleh Rigidoporus microporus merupakan penyakit penting pada tanaman karet. Pengendalian penyakit JAP umumnya menggunakan fungisida sintetik yang berdampak buruk terhadap lingkungan dan berbiaya mahal. Salah satu cara pengendalian penyakit tular tanah yang lebih murah dan efisien adalah pemanfaatan mikroorganisme antagonis. Penelitian ini bertujuan untuk menguji antagonisme jamur rizosfer tanaman karet (JRK) terhadap R. microporus.
