    Abstract

    On a 1.8 ha eggplant nursery with open drainage of the excess of nutrient solution the distribution of oxamyl was measured after it had been added to the nutrient solution. When it was applied via injection at a tap of a section, the distribution was more uniform than when applied via the central tank. Due to low irrigation rates it took eight days to distribute oxamyl from the section tap to all the plants in that section; in June one day was adequate. In January 2.2% of the applied dose was measured in the excess nutrient solution and in June 44.2%. It was estimated that 8.6% of the applied dose left the nursery via the central drainage pit.
