EFFECT OF PHENOLICS ON THE GROWTH OF TOMATO AND REPRODUCTION OF ROTYLENCHULUS RENIFORMIS

I. Mahmood, Z. A. Siddiqui

Abstract


Root dip treatments of phenolics viz. catechol, hydroquinone, phloroglucinol, pyrogallol and orcinol for 30 and 60 min. in different concentrations reduced multiplication of Rotylenchulus reniformis and improved growth of tomato plants. Improvement in growth was directly proportional to the concentration of phenolics (except higher concentration of hydroquinone which was toxic to plants) and time of root dip treatment. Among the phenolics used, hydroquinone was best fellowed by phloroglucinol, catechol, pyrogallol and orcinol.
