The optimum temperatures for growth of Botryosphaeria dothidea, the cause of Botryosphaeria panicle and shoot blight of pistachio, were 27-30 C on potato-dextrose agar. The optimum temperatures for pycnidiospore germination were 24-36 C. Pycnidiospores that germinated at 36-39 C failed to develop colonies. Optimum temperatures for disease development on artificially inoculated fruit were 27-33 C and for development of pycnidial initials and pycnidia on fruit, 30 C. The latent period for pycnidia development on pistachio fruit naturally infected by B. dothidea was shorter at 33 C than at 10-27 C []
