Interactive effects of treatments of ecological plant protection product Carbecol on the chlorophyll and carotenoids contents of tomato plants

Abstract

Plant pigments play a key role in the photosynthetic process of plants and their levels provide a physiological marker to evaluate plant health and determine stress response to application of different kinds of plant protection products. The aim of this work was to determine the response of leaf chlorophylls and carotenoids content in tomato plants to application of ecological plant protection product Carbecol alone or in combination with humic substances Ecolit. A greenhouse experiment was conducted in triplicate by employing distinct treatments of both Carbecol and biofertilizer Ecolit. Results showed that application of Carbecol increased the content of leaf pigments in tomato plants. The highest concentration of green photosynthetic pigments concentrations was registered in treatment with integrated application of Carbecol and Ecolit. Hence, experimental results demonstrated that the photosynthetic pigment status is affected by the application of plant protection product and humic substances.
