Both CaCN2 and urea inhibited the chlamydospore germination, mycelial growth and sporulation of the pathogen, but CaCN2 by using at the rates of 0.5 and 1.0%, had two inhibition zones for chlamydospore germination with time while urea had only one. Calcium cyanamide was also more effective on reducing mycelial growth and sporulation of the pathogen than urea did. Therefore, the suppression of pea wilt might be due to fungicidal effect of the intermediate products including hydrogen cyanamide and urea from calcium cyanamide.

C. gloeosporioides mycelium grew well on media with fructose and glucose as carbon source while sorbose and starch promoted sporulation. The mycelia of C. dematium grew well with maltose as carbon source while starch promoted sporulation. Of the nitrogen sources tested, organic nitrogens were beneficial for both mycelial growth and sporulation but chemical nitrogens suppressed both growth and sporulation.

The results showed that 13S5 and 13S8 tended to grow faster but sporulate less during subculturing. Sporulation was not significantly different in the first 6 generations, but after subculturing over 6 to 7 generations the sporulation declined significantly, by 81.7% and 69.0% respectively, as compared to that of the first generation.

The peak of lesion sporulation appeared on the 27th day. The most suitable temperature for sporulating was 24℃. If relative humidity was lower than 88%, the lesion could not sporulate. Between 90% and 100%, the higher the RH was, the higher sporulation was. If continuous humidity time was lower than 5 h, the lesion could not sporulate. Between 7 h and 24 h, the longer it was, the higher sporulation was.

Biological characteristics of the pathogen and the resistance of 13 cultivars of tea plant to tea brown blight were studied by means of natural infection in the field and artificial inoculation in vitro. Resistant cultivars and susceptible cultivars of tea plant were divided. And the resistance mechanism was researched tentatively. The findings are as follows: 1 Some biological characteristics of the pathogenic fungus The experiment result showed: the optimum temperature for the growth of fungus mycelium was from 24 to 27℃, the optimum temperature for sporulation ranged 22 to 30℃. Treated at 54℃ in 10 minutes, the spores didn't germinate. The optimum pH for the growth of the mycelium was 5.1～5.9, the optimum pH for sporulation ranged 5.0～6.0. Light had no much effect on the growth of fungus mycelium, but had much effect on the reproduction of the spore.
