Estimating the incidence of powdery mildew on cucumber plants in greenhouses in the Al Arabian area of Sirte

Abstract

This study aimed to estimate the prevalence of powdery mildew on cucumber plants in greenhouses in Sirte, through a field study in the Al Arbaeen area. Samples were collected from four targeted greenhouses and subjected to laboratory tests, which confirmed the presence of the disease in the selected greenhouses. Questionnaires were distributed to farmers in the selected greenhouses, and the data were analyzed to estimate the prevalence of powdery mildew. The results of the laboratory study showed the presence of powdery mildew in most of the samples collected from the Al Arbaeen area, indicating the prevalence of the disease in the region and the need to take measures to combat and limit its spread. It is essential to understand the symptoms of the disease and how to control it to maintain crop health and ensure good productivity in the region. Regarding the results of the field study, the average prevalence of powdery mildew in the four greenhouses in the Al Arbaeen area in Sirte was 20%. It was observed that the second greenhouse (with cucumber seeds) recorded the highest infection rate of 30%, while the first greenhouse (with pre-prepared cucumber seedlings) recorded the lowest infection rate of 20%.Powdery mildew was found to have spread throughout the studied area, and was detected in most samples taken from the Al Arbaeen area. This indicates the need to take measures to combat the disease and limit its spread. It is important to recognize the symptoms of the disease and take the necessary measures to maintain crop health and ensure high productivity in the region.
