Abstract

Kiwi is an important commercial fruit crop in China. Leaf spot diseases of kiwi caused by fungal pathogens seriously affect the growth of the fruit tree. In 2023, large areas of kiwi leaves suffered by black spot disease were observed in an orchard in Guizhou Province, China. A total of 230 leaves of twenty-five kiwi trees were randomly investigated, and the incidence of leaves with black spot symptoms was 19.13%. The disease caused leaf defoliation, leading to the significant reduction of quality and economic value of kiwifruits. The morphological characteristics, phylogeny based on the sequences of ITS, tub2, his3, cal and tef1 genes and pathogenicity of the disease-associated fungus were described in this study, confirmed Diaporthe hispaniae as the causal agent of leaf black spot disease of kiwi in Guizhou Province, China. Results in this study revealed the potential threat of D. hispaniae as a fungal pathogen to kiwi crop cultivation. Further researches, such as monitoring pathogen population and screening of effective fungicides, are required to develop effective strategy to control the kiwi leaf black spot disease caused by D. hispaniae.

期刊介绍： The Editors of Crop Protection especially welcome papers describing an interdisciplinary approach showing how different control strategies can be integrated into practical pest management programs, covering high and low input agricultural systems worldwide. Crop Protection particularly emphasizes the practical aspects of control in the field and for protected crops, and includes work which may lead in the near future to more effective control. The journal does not duplicate the many existing excellent biological science journals, which deal mainly with the more fundamental aspects of plant pathology, applied zoology and weed science. Crop Protection covers all practical aspects of pest, disease and weed control, including the following topics: -Abiotic damage- Agronomic control methods- Assessment of pest and disease damage- Molecular methods for the detection and assessment of pests and diseases- Biological control- Biorational pesticides- Control of animal pests of world crops- Control of diseases of crop plants caused by microorganisms- Control of weeds and integrated management- Economic considerations- Effects of plant growth regulators- Environmental benefits of reduced pesticide use- Environmental effects of pesticides- Epidemiology of pests and diseases in relation to control- GM Crops, and genetic engineering applications- Importance and control of postharvest crop losses- Integrated control- Interrelationships and compatibility among different control strategies- Invasive species as they relate to implications for crop protection- Pesticide application methods- Pest management- Phytobiomes for pest and disease control- Resistance management- Sampling and monitoring schemes for diseases, nematodes, pests and weeds.
