EFFECTS OF BIOPESTICIDE CARBECOL, FUNECOL AND BIOFERTILIZER ECOLIT ON PHOTOSYNTHETIC PIGMENTS AND HYDROGEN PEROXIDE CONTENTS IN TOMATO (Solanum lycopersicum L.) PLANTS

The photosynthetic pigments , hydrogen peroxide content is a physiological marker to evaluate plant physiology and determine the response to application of different kinds of plant protection products. The aim of this study was to determine the response of leaf chlorophylls and hydrogen peroxide contents in tomato plants to application of biofungicide Carbecol alone or in combination with biofungicide Funecol and biofertilizer Ecolit. A greenhouse experiment was conducted out with tomato (Solanum lycopersicum L., cv Manusa) plants. Experimental results showed that plant treatments with Carbecol increased the contents of photosynthetic pigments in tomato plants, in particular chlorophyll a. The highest concentration of photosynthetic pigments was registered in treatment with integrated application of Carbecol, Funecol and Ecolit. The treatments with Carbecol alone increased the concentration of hydrogen peroxide in leaves. The highest level of this metabolite in leaves was observed in treatment with application of biofertilizer Ecolit. The integrate use of biofungicides and biofertilizer Ecolit increased tomato yield by 14%.
