Plants are constantly targeted by many pests and insects. These insects and pests directly feed on the plants, sometimes eating up the produce. They also cause injury to plants and leave them vulnerable to many new diseases. They also act as carriers, transmitting disease causing pathogens, especially viruses into the plant. Insect attacks lead to heavy losses both in yield as well as in quality.
