Abstract

Bioeflicacy of carbendazim tolerant isolate of Trichoderma harzianum and exotic isolates of T. viride and T. virens were evaluated against dry ischolar_main rot pathogen of mungbean incited by Macrophomina phaseolina under glasshouse conditions. T. harzianum when applied to the soil besides being effective against the disease, increased seed germination by 96 per cent, plant height by 35.5cm and total biomass by 2.53 g/plant compared to T. viride and T. virens isolates. In addition, soil application of T. hazianum @ 5 g/kg and seed treatment @ 10⁸ conidia/ml was found effective against dry ischolar_main rot pathogen. Integration of T. harzianum as soil application (5g/kg) + seed treatment (10⁸C/ml) with sub-lethal doses of carbendazim (0.02%) significantly reduced dry ischolar_main rot incidence (95.3%) over soil treatment (91.5%) and seed treatment alone (86.5%).

Abstract

The object of the present paper is to study some properties of G ⊂ Γ introduced by D.Somasundaram [7], matrix transformations involving G and to introduce a special type of sequence spaces, which we designate as integral sequence spaces.
