Abstract

Corynespora cassiicola Causes Black Spots on Papayas One of the problems in papaya production is black spot disease which causes the appearance of the fruit to be less attractive and lowers the market price. This study aimed to isolate, identify, and determine the level of pathogenicity of the cause of black spot disease on papaya var. California. Identification was carried out based on morphological characters, while in vivo experiment was conducted using a completely randomized design with five replications. The treatment involved the vertical position of the fruits (first, second, third, fourth, and fifth), all fruit were inoculated with pathogenic fungi. The results showed that disease symptoms on papaya fruit involving small yellowish to dark brown spots is caused by the fungus Corynespora cassiicola. The fungus C. cassiicola has black-brown colonies, the surface of the colonies is smooth with flat edges, and curved like velvet. This fungus has a few upright conidiophores bent, septa, single and some are branched, brown, while the conidia are single, slightly bent, and septa 2–12. The pathogenicity of this fungus is moderate. The fastest incubation period occurred in fruit with the fourth vertical position, the largest disease spot areas was in the fruit in the first vertical position, and the highest disease severity was in the fruit with the first vertical position.

Abstract

The Gatos Farmers Group in Sumpiuh Village, Banyumas District, has consistently cultivated organic rice over the past two years. This initiative was driven by awareness of the negative impacts of conventional rice farming, particularly the use of chemical inputs, on both the environment and human health. As part of the support provided to the organic rice cultivation efforts of the Gatos Farmers Group, this community service program involved organic pesticide production training and pratice, aimed to enhance farmers' knowledge and equip them with technical skills to produce organic pesticides using natural materials readily available in their surroundings. The training began with participatory planning, followed by lectures on the subject, and continued with hands-on practice in making organic pesticides. The training successfully improved farmers' knowledge of organic pesticides, as evidenced by the increase in post-test scores compared to pre-test scores, further validated through statistical testing using a paired sample t-test. Post-training monitoring indicates that members of the Gatos Farmers Group have adopted organic pesticide production and applied it to their rice farming.
