The latest data indicate that pests reduce the yield of agricultural crops in the world for 42% and in Europe for 28%. Approximately one half wastes on weed damage, one quarter on disease, and second quarter on pest damage. It is also important to draw attention to responsibility of individuals for the application of plant protection measures, which is prescribed by each state. This responsibility exists because of the danger of pesticides for humans, animals and the environment. All farmers have to worry not only about preventing the spread of quarantine, but also for spread of many other pests. In fact, many measures of plant protection give the desired success only if implemented systematically, affecting larger areas. Success of farmer's production depends of whether the other farmer, his neighbor, acts on the same way. By improper application of pesticides, for example by stronger wind, an individual can contaminate nearby crops and plantations over permitted threshold values, can poison a neighbor's bees, and with negligent application of herbicides can damage and even destroy crops and plantations nearby. Crop protection is the science and practice of managing pests, plant diseases and other pest organisms that damage agricultural crops.
