Taphrina pruni being larger than the healthy one. As a fungus, cool and wet weather conditions promote the germination of spores, whilst warm and dry weather results in infection rarely taking place. Colonisation can become extensive and eradication very difficult. The disease can to some degree be controlled by carefully removing infected branches, witch's brooms and fruit before the infective air borne spores are produced. Applications of copper-containing fungicides have a degree of control over the fungus. Taphrina pruni Taphrina pruni is a fungal plant pathogen of blackthorn (Prunus spinosa) that causes the Pocket or bladder Plum gall, a chemically induced distortion
Prunus kansuensis locally. The fruit is eaten by the endangered golden snubnosed monkeys ("Rhinopithecus roxellana"). Prunus kansuensis Prunus kansuensis (), sometimes called the Chinese bush peach, is a putative species of peach native to China. It is found in Gansu, Guizhou, Hubei, Qinghai, Shaanxi and Sichuan provinces. It is a shrub or tree tall, preferring to grow at above sea level. A genetic and morphological study has shown that it is conspecific with "Prunus persica", the cultivated peach. "P.kansuensis" is being investigated as a source for rootstocks and for crop improvement due to its resistance to multiple diseases, to drought, and to
