ISOLASI DAN IDENTIFIKASI PATOGEN PENYEBAB PENYAKIT LODOH PADA SEMAI KALIANDRA (Calliandra callothyrsus)

Abstract


Procurement of qualified forest tree seeds is one of the determinants of the sustainability of forest management. Pathogen attacked in the nursery is one of the causes of the unfulfilled targets for the provision of seeds of forest crops needed. Therefore, the development of disease in the nursery need to be studied in order to make precautionary or control measures appropriately. The aim of this study is to isolate and identify causes of damping off which causing death in seedling of  Kaliandra (Calliandra callothyrsus).

Seedling of Kaliandra which consists of 6 family numbers and come from 2 provenans Papua and NTT shows death due to damping off disease. Seedling of Kaliandra which showed death isolated then isolates were observed macroscopically and microscopically ,Postulat Koch test was done to identify cause of disease causing death at Kaliandra seedling.

The results of identification indicate that the causes of damping off disease are Fusarium sp and Rizoctonia sp.
