Phytophthora infestans

Phytophthora infestans is a type of microorganism known as an oomycete, which causes the potato blight disease. It infects potato plants and tomatoes, leading to dark, rotting spots on leaves, stems, and tubers. This pathogen spreads rapidly through water and wind, causing significant crop damage and economic loss. It thrives in cool, damp conditions and can develop quickly, making effective management essential. Understanding and controlling Phytophthora infestans is important for protecting food supplies and maintaining healthy agriculture.
