EFFECT OF ECOLOGICAL PRODUCT CARBECOL AND BIOFERTILIZER ECOLIT ON MANAGEMENT OF LATE BLIGHT (PHYTOPTHORA INFESTANS) AND PRODUCTIVITY OF TOMATO (SOLANUM ESCULENTUM) PLANTS

Abstract

Organic agriculture is gaining importance and the market for organic products has been significantly increasing nowadays. Different diseases affect tomato especially the pathogen Phytophtora infestans, which is a major threat in organic and durable agriculture. A greenhouse experiment was carried out to evaluate the effect of new biorational protection product Carbecol and humic substances Ecolit in late blight management in tomato and their impact on the productivity. Tomato plants during vegetation period were treated four times with Carbecol in dose 6 kg/ha alone as well as in combination with application of biofertilizer Ecolit in doze 3L/ha. Control were untreated plants. Experimental results revealed that foliar diseases like late blight of tomato were significantly reduced by treatments applied either alone or in combinations compared to untreated plants. However, the best results were obtained in variant with integrated application of Carbecol, Ecolit plus ecological protection product Funecol in concentration 0,4%. The treatments had beneficial impact on fruits productivity of tomato. Experimental results demonstrated that application of Carbecol alone did not significantly increase the yield. However, the integrated use of Carbecol, humic substances Ecolit and Funecol gave better effect and the yield increased by 15,7% compared to untreated plants. Hence, experimental data suggests that the combined application of Carbecol, Ecolit and ecological fungicide Funecol could reduce the incidence of Phytophtora disease and increase tomato productivity. The integrated application of these ecological products of plant protection and biofertilizer could be an option for development of durable agriculture.
