Disease Occurrence, Incidence and Severity in Vegetable Gardens of Green-the-Home Project Beneficiaries in Baybay City and Hilongos, Leyte, Philippines

Abstract

This survey aimed to identify the major diseases affecting the Green-the-Home (GTH) vegetable gardens project beneficiaries in Barangays Guadalupe and Marcos in Baybay City, Leyte, and Barangay Liberty, Hilongos, Leyte, Philippines. The study documented the occurrence, incidence, and severity of various vegetable diseases, including the existing pest management practices of vegetable growers. Disease incidence and severity observed in vegetable gardens varied depending on the type of disease, crop, and site. The surveyed crops included okra, upo, ampalaya, tomato, string beans, sweet pepper, chili, eggplant, and cucumber, which are common in the sampling areas. The most common diseases found within the three project sites were okra leaf mold, Cercospora leaf spot of ampalaya, Cercospora leaf spot of sweet pepper, and Cercospora leaf spot of chili. The majority of vegetable growers employed physical and cultural pest management approaches, such as weeds removal (66.6%), the use of nets (63.3%), intercropping (60%), tillage (50%) and bagging (46.6%). Disease occurrence in the areas was influenced by environmental factors such as rainfall, temperature, humidity, and poor management practices of vegetable gardens. Since Baybay and Hilongos have the same climatic pattern, such environmental factors are consistent in both areas. It is recommended that the Government and other lead agencies, such as the Department of Agriculture (DA) and the Agricultural Training Institute (ATI), assist GTH in promoting pests and diseases literacy programs among vegetable growers. They should also provide adequate access to extension services and disseminate appropriate, safe, and long-term pest management strategies to vegetable growers.
