Alternaria leaf spot of chilli caused by Alternaria alternate is an important disease affecting chilly production areas in India. The disease is primarily controlled through the use of fungicidal seed treatments. In this study, different fungicides viz. Captol, Captan, Ziram, Captofol, Thiram, Indofill Z 78 and Indofill Z 45 were assessed for their ability to reduce the growth of Alternaria alternata under laboratory conditions. Maximum inhibition (100%) was achieved by Captol and capton followed by captofol (89.5 %) while 0.1 % dose given. This paper reports the efficacy of fungicides that can be used under field conditions to control alternaria leaf spot in tropical regions and demonstrates the use of a method of application that could significantly improve the efficacy of disease control.
