Author(s): Sachin Jadhav
Abstract: Genus Alternaria belong to deuteromycetes having number of species and destructive plant pathogen to the families such as Solanceae, Cucurbitaceae, Brasicaceae. Tomato belong to family Solanaceae. The tomato crop grown in rabbi and kharip season having nutritional and economical value. Alternaria species cause early blight disease of tomato and lose the quality and quantity of crop. The disease is control by spraying synthetic chemicals but it creates environmental, ecological problems. Now a day’s biological methods are uses to control the diseases. Biological methods are safer, biodegradable and ecofriendly, so this method is adopted by farmer rather than chemical control method. Biological agents like fungi, herbal extract and natural products are used to control diseases. In present study Alternaria alternata isolated from infected parts of tomato plants on PDA medium. The different concentrations of some plant latex are prepared and used to control the infection of Alternaria.
