Fusiform Rust primarily affects which part of the plant?

Fusiform Rust primarily affects the stems of pine trees. This fungal disease, caused by the organism Cronartium quercuum f. sp. fusiforme, forms galls or swellings on the stems, which can significantly impact the tree's health and structural integrity. The galls can disrupt the flow of nutrients and water within the tree, ultimately leading to stunted growth or even death in severe cases. Understanding the specific part of the plant that Fusiform Rust targets is crucial for effective management and control strategies. This knowledge enables proper scouting, identification of symptoms, and timely intervention to mitigate damage to affected trees.
