EFFECTS OF TREATMENTS WITH BIOPESTICIDE CARBECOL AND FUNECOL ON TOMATO (SOLANUM LYCOPERSICUM. L) LATE BLIGHT

Tomato late blight (Phytophtora infestans) is a major disease of tomato (Solanum lycopersicum L.) in many agricultural regions, causing huge losses in vegetable production. A greenhouse experiment was conducted to investigate the efficacy of the new biofungicide Carbecol alone or in combination with treatments of the biofungicide Funecol in the control of late blight in tomato and their impact on crop productivity. Tomato plants were treated four times during the growing period with Carbecol alone or in combination with treatments of Funecol at different concentrations to control late blight of tomato. The experimental results revealed that foliar disease of late blight in tomato was significantly reduced by treatments applied in combinations of Carbecol and Funecol in comparison with untreated plant or Carbecol alone. However, the best results were reached in the variant with integrated application of Carbecol at a rate of 0.4% plus treatments with Funecol at a rate of 0.4%. The treatments had a beneficial effect on the tomato fruit production. The integrated application of Carbecol and Funecol gave the best effect and the yield increased by 16% in comparison with untreated plants.
