Disease Prevention & Treatment

Plant diseases, caused by pathogens like fungi, bacteria, viruses, and nematodes, pose significant threats to crops and ecosystems. Fungi, such as powdery mildew and rusts, thrive in warm, moist conditions and spread quickly. Bacterial diseases, like wilts and leaf spots, enter plants through wounds and can spread via water or insects. Viruses, transmitted by insect vectors, cause symptoms like stunted growth and leaf distortion. Nematodes damage roots, leading to stunting and wilting. Parasitic plants like dodder drain nutrients from hosts. Control involves cultural practices, resistant varieties, and sometimes chemical treatments. Research aims to improve prevention and management strategies for sustainable agriculture.
