Diseases of fungi origin are important diseases of Telfairia occidentalis (fluted pumpkin) in the main growing areas of the leafy vegetable in Cameroon. A study was conducted between March and June in the cropping seasons of 2019 and 2020 in Dschang to determine the influence of sowing date and removal of diseased leaves on the incidence and severity of leaf spot disease caused by Phoma sorghina. There were four sowing dates, with no variation in planting distance in the two cropping seasons. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Each replication had three experimental units with similar sowing dates. Seeds were sown at the rate of 1 m × 1 m, with four seeds per experimental unit. Data for disease incidence and severity was recorded every fortnight, commencing three weeks after emergence (WAE.. View more»
