The effects of sunscald on branch rot in sweet cherries and its prevention and control

PENG Wei， ZHU Lixia， XIANG Xiaogang， HU Deyong （Xixiang County Agricultural Technology Extension and Training Center， Xixiang，Shaanxi 7235oo，China） Abstract： In Hanzhong City， Shaanxi Province， sweet cherry trunk rot most frequently occurs on the southwest-facing side of the main trunk， as well as on the sun-exposed surfaces of branches on the east， northeast， and north sides that spread out at a wider angle.Therefore，analysis indicates that sunscald is closely related to sweet cherry trunk rot. Sunscald damages the bark， weakens tree vigor and resistance， and creates favorable conditions for pathogen infection. It also attracts bark-boring insects， leading to a combined “fungal and insect” damage. This study proposed comprehensive measures for the integrated control of sweet cherry stem rot， including optimized cultivation management， physical control methods， and chemical control of pests and diseases.
