Whiteflies
Whiteflies are small, soft-bodied, winged insects closely related to aphids and mealybugs. They are moth-like in appearance, about 1/16 inch long, triangular in shape, and gray-white in color. These sap-sucking pests feed on plant tissue, causing yellowing, stunted growth, and wilting. They also excrete honeydew, which attracts ants and promotes sooty mold growth. Whiteflies can transmit serious plant viruses.

Root Rot
Root rot is a serious fungal disease that affects the root system of plants, causing them to decay and die.

The disease thrives in waterlogged conditions where roots are deprived of oxygen, making them susceptible to fungal infection.
