Bacterial wilt is a serious plant disease caused by soilborne bacteria that block water movement inside stems, leading to sudden wilting, yellowing, stunted growth, and plant death. It commonly affects tomato, potato, chili, eggplant, and many vegetable crops, especially in warm and moist conditions. Management includes resistant varieties, field hygiene, crop rotation, drainage improvement, and removal of infected plants. Biological control products can help suppress harmful pathogens naturally. Novobac BACTONUS is listed as a bio bactericide designed for bacterial wilt control in crops, supporting root-zone protection and healthier plant growth with beneficial microbes.
