Deskripsi

Botryosphaeria panicle and shoot blight of pistachio caused by the fungus Botryosphaeria dothidea is favored by high temperatures, 80° to 85° F, and wetness periods longer than 12 hours. Based on these requirements, the disease becomes severe in late spring and summer when temperatures increase and after sprinkler irrigations begin. The disease was substantially reduced by shortening sprinkler irrigations from 24 to 12 hours and from 48 to 24 hours in two commercial pistachio orchards in the Sacramento and San Joaquin valleys, respectively.
