A variety of microorganisms, nematodes, fungi, insects, harmful birds and other animals (vertebrates) can cause considerable damage as well as high yield and quality losses. This is particularly true in intensive crops such as cereals, vegetables, fruit and grapes. According to long-term experience, the yield loss for wheat is at least 30% and for rice around 50%. Plant protection is therefore of particular importance with regard to securing the world's food supply. Until the 1950s, it was common practice worldwide to use massive amounts of chemicals in the fight against pests, because little was known about the negative effects. Climate change also contributes to negative development.
