 Abstract

Plant propagation and nursery management is a vital link in the production of quality planting material. Experiments were carried out during 2005-2008 to study the occurrence of diseases on seedlings of guava and the effect of weather parameters on the incidence and severity of anthracnose disease in different major growing areas of Bangladesh. Important plant pathogens viz. Colletotrichum gloeosporioides and Fusarium oxysporum were detected and identified. Incidence and severity of anthracnose of guava varied significantly from season to season as well as from location to location and was also positively correlated with temperature, rainfall and relative humidity.

Key words: Seed, Seedling, Guava, Fruit, Disease, Management
