Text 1.What is plant protection and why it is so important?

Ever since humans have relied on planted crops as the main source of food, plant diseases, insects, rodents, weeds and other pest organisms have been a constant threat to food supply.

The term 'pest' is used throughout this website to refer to all biotic agents that cause diseases of crops and other valued plants, insects, plant-parasitic nematodes, mites and vertebrates that feed upon them, and weeds that compete with them.

The biblical locust plagues, the potato blight epidemic that killed millions of people in Ireland in the 1850s, and the complex of pests that have attacked rice crops throughout Asia for thousands of years are just some examples of the devastation that pests can cause. More recently, while estimates of potential global losses due to insect and vertebrate pests, diseases and weeds varies from crop to crop, it has been estimated that these pests possibly cause up to 40% of the world’s production of food by reducing crop yield and causing losses in storage.

An integrated approach to plant protection

The mission of the International Association for the Plant Protection Sciences (IAPPS) is to promote and support an integrated, scientific approach to plant protection. Embracing a wide range of research approaches, technologies and practices, IAPPS aims to encourage the development and implementation of plant protection practices that provide farmers with ecologically sustainable and socially acceptable means of preventing and controlling pests, obtaining an economically profitable yield and, at the same time, assuring the resilience and long term viability of crop production and protection systems.
