Abstract
The toxin production of Corynespora cassiicolai Wei and its toxicity to different cucumber varieties were studied in the paper.The results showed that the appropriate conditions for toxin production were pH value 6,temperature 25℃,lightening for 12h/d and continuous shaking culture for 15 days.The toxicity of the pathogen was different to different cucumber varieties.Toxicity was the strongest to Jinchun No 3,while it was the least to Zhongnong No 5.
