Biological characteristics of black leaf spot of rubber caused by Alternaria heveae was researched. The results showed that hyphae optimum growth temperature was 30℃, the most suitable growth pH was 7~8, lethal temperature was 52℃treatment 10 min. The pathogen can effectively use a variety of carbon source and nitrogen source, and lactose and rat lee sugar as the highest carbon source utilization, beef extract and yeast extract as the optimum nitrogen source; Different light treatment had significant effects on mycelial growth and 24 h lighting condition was more advantageous to mycelial growth.
