Abstract

Background: Plant pathology addresses the study of diseases and pests affecting the plant kingdom, which cause significant agricultural losses and ecosystem damage globally. Understanding the nature and interactions between plants, pathogens, and pests is crucial for effective disease control. Diseases caused by fungi, bacteria, viruses, and pests such as insects and nematodes contribute to reduced crop yields and food insecurity. Methods: This study used field observation and laboratory-based diagnostic techniques to identify and analyze plant pathogens and pests in various crops. Molecular techniques were employed for pathogen identification, while Integrated Pest Management (IPM) strategies were implemented to control pest outbreaks. Results: Fungal infections, such as *Phytophthora infestans* in potatoes, and viral diseases like Tobacco Mosaic Virus (TMV) in tomatoes were identified. Insect pests, including aphids and caterpillars, were also prevalent. IPM strategies involving biological control, crop rotation, and resistant varieties successfully mitigated pest damage in treated plots by 60%. Results from molecular techniques confirmed pathogen identity, aiding in the development of effective control measures. Conclusion: The study highlights the significant impact of plant pathogens and pests on crop health and food production. Integrated management strategies combining chemical, biological, and cultural practices effectively reduced disease and pest prevalence, improving plant productivity. Future efforts should focus on developing resistant varieties and adopting sustainable farming practices to mitigate plant diseases and pests.

Keywords: Plant pathology, diseases, pests, fungal infections, viral diseases, Integrated Pest Management, crop health, agricultural losses.
