Chemical plant protection. Past. Present. Future?
After the discovery (1938) and huge commercial and popular success of the insecticide DDT (Figure 1, Nobel Prize for its discoverer Paul Müller in 1948) a number of chemical companies started to develop new pesticide active ingredients. The demand for such chemicals was high: they were inexpensive and highly efficient replacements for earlier labor-intensive crop protection practices. As a result, the number of newly developed pesticides increased continuously and their use spread out to almost all areas of human activities from household crop production to households, forestry, food storage, etc.
