Reseña del libro "Praxisnahe Tracerversuche Zum Verbleib Von Pflanzenschutzwirkstoffen Im Agrarökosystem (en Alemán)"
According to the FAO's latest estimates, the world food supply can only be guaranteed if the 1982 agricultural production is increased by approx. 50% by the year 2000. 3 of this production increase must be achieved on areas already under cultivation. This means that in addition to balanced mineral fertilization the use of pesticides will have to be intensively continued in order to fully exploit the im- proved yield potential of the cultivated plants achieved by breeding. The primary research objective is therefore to extend our knowledge of the uptake and effects of pesticides in the plant as well as their persistence in agricultural ecosystems in order to be able to apply them both more efficiently and more safely. The Institute of Radioagronomy at the Kernforschungsanlage JUlich GmbH QUlich Nuclear Research Centre) is carrying out practical experiments into these problems using 14C-Iabelled pesticides under field conditions. In this way state- ments will become possible on the uptake and residue situation in plants, trans- location and metabolism in the soil, the balance in the year of application as well as on the uptake of untreated cultures in the crop rotation. Parallel to this, uptake after leaf spraying or after seed grain treatment is being studied under standardized conditions, as well as for example the mineralization, sorption and fixation of active substances and metabolites in the soil. Results from the past 12 years are being utilized as a basis for an evaluation of the state of knowledge.
