| Abstract: | Objective] The purpose was to provide a reference for the prevention and treatment of apple bitter rot in order to improve the quality and economic benefits of apples.Method] The pathogen,pathogen infection characteristics,pathogenesis regularity,signs and kinds of prevention and treatment methods of apple bitter rot were studied.Result]The results showed that it entered onset peak when the temperature was 28-29 ℃ and relative humidity was above 80%.Fruit plants,small spacing,large crown or partial nitrogen too much may cause apple bitter rot easily.Low-lying,poor drainage or the tree breakdown may cause a heavier disease.Conclusion] Pathogens passed through winter by living in mycelia,conidiospore dish,dead fruit,fruit,dry branches or broken injury etc and infection the young fruit from the beginning.The occurence or growth of disease is related with the climate,varieties and cultivation. |
