 Abstract

Liriomyza trifolii (Burgess) (Diptera: Agromyzidae) is one of the most serious pests in greenhouses. The aim of the study is to investigate the effects of foliar fertilizers, such as calcium nitrate, fulvic acid and their combinations on L. trifolii population and tomato yield under greenhouse conditions in spring and fall of 2009. It was shown that fulvic acid and calcium nitrate combinations had negative effect on L. trifolii population in growing tomato plants. In addition, fulvic acid and calcium nitrate combination increased yielding by 23%.

Key words: Liriomyza trifolii, fulvic acid, calcium nitrate.
