Abstract
Experiments on the biological control of
Macrophomina phaseolina of mashbean roots were carried out at two different filed locations viz., Karachi and Islamabad. Infection and or colonization of mashbean roots by M. phaseolina reduced significantly (P=0.01) at both field locations where seeds were treated with Paecilomyces lilacinus. Trichoderma hamatum, Gliocladium virens and Aspergillus candidus. T. harzianum, T. viride and Streptomyces sp., were effective in Karachi soil but not in Islamabad soil,
whereas, Rhizobium meliloti failed to reduce
M. phaseolina infection at any field location.
