“…distributed worldwide (Kobayashi 1970, Old et al 1991, Adams et al 2005. Valsa sordida (anamorph: Cytospora chrysosperma) is the causal agent of canker on different species of plant genera, Populus and Salix, and more rarely on other angiosperms all over the world (Abbasi et al 2015, Kaistn et al 2015. Because of V. mali were isolated and identified from Salix matsudana, Populus spp., it may become a common pathogenic of canker disease transmission between shelter forest and economic forest.…”

Cytospora species are found in Xinjiang with stem canker disease. Cytospora species were identified based on morphological characteristics and molecular biology from economic forests and shelter belt in Xinjiang. A total of 281 isolates were obtained from woods canker of 17 hosts in Xinjiang. The strains identified were Valsa mali (anamorph: Cytospora sacculus), Valsa sordida (anamorph: Cytospora chrysosperma), Valsa macolica (anamorph: Cytospora schulzeri), Leucostoma niveum (anamorph: Cytospora nivea) and Cryptosphaeria pullmanensis (anamorph: Cytosporina pullmanensis). The V. mali and V. sordida wwere the main pathogens of economic forest and shelter forest, respectively. It is also hoped that this will lead to improve management strategies for diseases associated with these fungi. Bangladesh J. Bot. 51(4): 1029-1037, 2022 (December) Special

“…This pathogen is widely distributed in the northern regions of China [13,14], posing a severe threat to poplars. In fast-growing poplar plantations, the incidence of Valsa canker ranges from 20% to 40%, reaching over 90% in some cases [15][16][17], causing substantial economic losses to commercial forestry. Against this background, V. sordida was investigated in this experiment.…”

A key step in the study of tree pathology is the identification of appropriate method for inoculating pathogens of diseases in branch and trunk. Pathogens of diseases in branch and trunk are commonly inoculated through punching, burning, and toothpick inoculation. However, there is a lack of comparative analysis of the inoculation outcomes of these three methods. In this work, Six‐year‐old P. alba var. pyramidalis were inoculated with V. sordida, using punching, burning, and toothpick techniques, respectively, to investigate the differences in the effectiveness of these inoculation methods. Results reveal that the incidence rate was 93.55% in the toothpick inoculation group, significantly higher than 80.65% in the burning inoculation group (p = 0.007), while punching inoculation exhibited significant pathological responses in the early stages, with spontaneous healing in the later stage. Addi-tionally, toothpick inoculation was more efficient in inducing Valsa canker when inoculating the pathogen at the bottom of the tree, with lower intra‐ and inter‐row spacing (stand density) providing better outcomes than higher intra‐ and inter‐row spacing. The results of this study demonstrate that toothpick inoculation is an optimal option for studying the artificial inoculation of V. sordida in six‐year‐old P. alba var. pyramidalis, providing technical support for research on poplar diseases and offering a theoretical basis for the inoculation of other diseases in branch and trunk.
