Alternaria macrospora

There is a need and scope for exploiting sources of alternative chemotherapeutants which are reserved in many plant species Based on the importance of Alternaria leaf spot, the present investigation was carried out with a view to find out the efficacy of bacterial biocontrol agents and botanicals against A. macrospora.

Biological agents provide economical and relatively non-polluting delivery systems for protective materials compared to other chemical methods and biocontrol measures against plant pathogens are widely recognised as a step towards ecofriendly farming. The present investigation carried out to know the interactions of Trichoderma spp. with Alternaria macrospora causing leaf spot of cotton.

Eleven fungicides viz., thiram, captan, copper oxychloride, mancozeb, chlorothalonil, carbendazim, hexaconazole, propiconazole, combination products of carbendazim + mancozeb, captan + hexaconazole and azoxystrobin (each at recommended dose, 500 ppm below their recommended dose and 500 ppm above their recommended dose) were evaluated in vitro against Alternaria macrospora causing leaf spot of cotton.

Eight systemic fungicides viz., Propiconazole, Hexaconazole, Difenconazole, Tebuconazole, Benomyl, Carbendazim, Tridemoph and Thiophanate methyl (each @ 500 and 1000 ppm concentration) were evaluated in vitro against Alternaria macrospora causing leaf spot of cotton. All the treatments significantly inhibited mycelial growth of Alternaria macrospora over untreated control. Among eight fungicides Propiconazole, Hexaconazole, Difenconazole and Tebuconazole at both (@ 500 and 1000 ppm) concentration inhibited 100 per cent growth of A. macrospora.
