Rust
Rust is a common fungal disease caused by fungi in the order Pucciniales that affects a wide variety of plants. The disease gets its name from the characteristic orange, yellow, or reddish-brown pustules that appear on leaves, resembling metal rust. This obligate fungal parasite requires living plants to survive and can cause significant economic losses in agricultural crops.

Apple scab
Apple scab is a serious fungal disease caused by Venturia inaequalis. It creates dark, olive-green to black spots on leaves and fruit. If left untreated, it can cause leaves to fall off early and make the fruit cracked or deformed. The fungus survives winter in fallen leaves and spreads through rain and wind during wet spring weather.

Spider Mites
Spider mites are tiny arachnids (less than 1/20 inch long) related to spiders and ticks that feed on plant sap. They thrive in hot, dry conditions and can cause significant damage to ornamental and vegetable plants. During severe infestations, crop losses can reach 14% or higher as these pests disrupt vital plant processes including photosynthesis, carbon dioxide absorption, and transpiration.
