Abstract

Chemical plant protection and its perspectives in ČSSR

A number of 374 chemical preparations for plant protection are licenced in ČSSR. Yearly more than 5.5 millions ha of tilled land are treated with chemical pesticides. The parts of effective groups in the plant protection measures amount to: herbicides = 62%, fungicides = 16%, biological preparations = 12.7%, insecticides = 9.3%. Chemical control actions injure the structure of agrocoenoses, therefore integrated control measures must be introduced for the purpose of reducing the injuries as far as possible. Solely when the critical number of a pest species is overstepped chemical control should be applied. In ČSSR 8 species of animal pests are objects of prognosis; 23 animal species as well as a virus disease and 2 mycoses are objects of the warning service.
