Karakterisasi Jamur Patogen Penyebab Penyakit Pada Tanaman Srikaya (Annona Squamosa) di UD. Sabila Farm

Introduction

Karakterisasi jamur patogen penyebab penyakit pada tanaman srikaya (annona squamosa) di ud. Sabila farm. Identifikasi jamur patogen (Colletotrichum sp., Fusarium solani sp., Curvularia sp.) penyebab penyakit pada tanaman srikaya (Annona squamosa) di UD. Sabila Farm untuk strategi manajemen penyakit efektif.

Abstract

Soursop (Annona squamosa) is a horticultural crop with high economic value. However, this plant is susceptible to diseases caused by pathogenic fungal infections, which can reduce yield and fruit quality. This study aims to identify pathogenic fungi affecting soursop plants at UD. Sabila Farm and understand their role in disease development. The research was conducted at UD. Sabila Farm, located in Kapanewon Pakem, Sleman Regency, Special Region of Yogyakarta. Further laboratory analyses were carried out at the Biology Laboratory, Faculty of Agriculture, Universitas PGRI Yogyakarta. The study employed field exploration and laboratory identification using Potato Dextrose Agar (PDA), samples were collected from leaves, stems, and fruits showing signs of infection. The findings revealed several fungal pathogens contributing to plant diseases, such as Colletotrichum sp., Fusarium solani sp., and Curvularia sp.. Morphological characterization and pathogenicity analysis provide a foundation for developing effective disease management strategies. This research is expected to support farmers in maintaining plant health and improving soursop production sustainably.

Review

This study addresses a critical issue concerning the health and productivity of soursop (Annona squamosa), a horticultural crop of significant economic value. The objective to identify pathogenic fungi affecting soursop plants at UD. Sabila Farm and understand their role in disease development is clearly articulated and highly relevant to agricultural practice, particularly in the specified region of Yogyakarta. The methodology, involving field exploration and subsequent laboratory identification using standard techniques such as Potato Dextrose Agar (PDA) with samples from various infected plant parts (leaves, stems, fruits), appears appropriate for achieving the stated aims. The research sets a foundational step towards understanding the etiology of soursop diseases in the local context. A significant strength of this research lies in its identification of specific fungal pathogens, namely *Colletotrichum* sp., *Fusarium solani* sp. (likely intended as *Fusarium solani* or a member of the *F. solani* species complex), and *Curvularia* sp. These findings are crucial as they provide concrete targets for disease management. The abstract also mentions morphological characterization and pathogenicity analysis, which are essential components for robust pathogen identification and confirmation of their role in disease development. This information is invaluable for developing targeted and effective disease management strategies, directly supporting farmers in maintaining plant health and ultimately improving soursop production, aligning with the goal of sustainable agriculture. While the abstract provides a promising overview, the full manuscript would benefit from a more detailed elaboration on several aspects. For instance, a comprehensive description of the morphological characteristics used for identification and the specific methods employed for pathogenicity analysis (e.g., adherence to Koch's postulates) would strengthen the scientific rigor. Furthermore, including quantitative data regarding the incidence or severity of diseases caused by each identified pathogen, or their prevalence across different plant parts, would add substantial depth. Consideration of environmental factors influencing disease development and, if possible, initial thoughts on potential specific management strategies derived from these findings would enhance the practical impact of the study. Despite these points for further detail, the study presents a valuable initial characterization of soursop pathogens, forming a solid basis for future research and practical application.
