Spiral Sorrel (Oxalis spiralis)

Slugs and snails are mollusks that feed on plant tissue, causing irregular holes in leaves and damage to young seedlings. They are most active at night and in moist conditions, leaving characteristic silvery slime trails. These pests can quickly devastate gardens, especially during wet seasons.

Curculionidae (weevils) are small beetles that feed on plants. Adults chew leaf margins, leaving crescent-shaped notches, primarily at night. The larvae live in the substrate and consume roots, causing decline, yellowing, and wilting even when the substrate is moist, and in severe cases, plant death. They frequently affect ornamentals and garden plants such as strawberries, citrus, roses, hydrangeas, azaleas, blueberries, begonias, and many potted plants.

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.

Root rot is a serious fungal disease that affects the root system of plants, causing them to decay and die. It is primarily caused by overwatering, poor drainage, or soil-borne fungi such as Pythium, Phytophthora, Rhizoctonia, and Fusarium. The disease thrives in waterlogged conditions where roots are deprived of oxygen, making them susceptible to fungal infection.
