Preliminary Study on the Occurrence Dynamics of Cordana Leaf Spots in Banana in Hainan Province
摘要
Abstract
To clarify the occurrence and impact of Cordana leaf spot of banana in Hainan Province,a systematic investigation was conducted from February 2023 to January 2024 on the main cultivated variety'Haigongjiao'in Hongguang Farm,Fushan Town,Chengmai County,using a fixed-point periodic method to study the dynamics of Cordana leaf spot in the field.The results revealed that Cordana leaf spot can occur throughout the year,with an epidemiological curve that is nearly S-shaped.During the growing season from June to November,the disease index increased progressively with the growth stage of the banana plants,peaking in April and November,with the highest peak occurring in November.Humidity was identified as a crucial factor influencing the dynamics of Cordana leaf spot,with rapid disease expansion occurring during the rainy season.Additionally,continuous drizzle in autumn and at the transition between spring and summer also contributed to the spread and expansion of this disease.关键词
