Effect of Temperature, pH and Photoperiod on the Growth of Alternaria petroselini (FCLW#23) for the Mycoherbicidal Management of Weeds of Leguminous Crop
Keywords:
Alternaria petroselini (FCLW#23), pH, Temperature, Photo period.Abstract
Pulses are the most important food crops after cereals, constitute the major source of dietary protein. India is the world's largest producer and the largest consumer of leguminous crop. The plant pathogen causes the some effect on weeds as the phytotoxin it produces it would be possible to use either the pathogen or the phytotoxin as a Bio-herbicide. However have limitations that often make their use impractical with current technology. Alternaria petroselini (FCLW#23) was isolated from weeds of leguminous crop. The effect of various parameters like temperature, pH and photoperiod were investigated for the growth of Alternaria petroselini (FCLW#23) used as a mycoherbicidal agents. Results of experiment indicated that the maximum phytotoxic effect in temperature 28°C and pH range of 5.0. The Alternaria petroselini (FCLW#23) was grown under different photoperiod. Good mycelium growth was recorded with 24 hours continuous darkness.
