Plants are living organisms and, like any living organism, are susceptible to disease. From fungal diseases to viral and bacterial infections, there are many different diseases that plants can fall victims to. The interactions between plants and disease organisms are complex. Understanding basic concepts and principles of how diseases develop, could be half a way to their management.
Many insects, like caterpillars and leaf beetles, mites and nematodes feed on plants. We call these animals phytophagous. If their population growth is too high or they are very specialized to certain plant species, they become pests and cause significant damage in agriculture, horticulture, forests and other ecosystems. In some instances plants themselves can become or be considered pests, if they are invasive and harmful to other plant species and different organisms.
