Trichoderma spp. were known to have antagonistic activity against many soil borne diseases. In this experiment we prepared five different formulations of asperellum and stored them in normal temperature. Later the efficacy all checked sheath blight disease rice both in-vitro in-vivo. Among F5 [Trichoderma grown potato dextrose broth (500ml) + Talc(500g)] treated plants showed very good result m...

Soil fumigation induces an ‘increased growth response’ (IGR) in crops of about 35%, even in soils with low pathogen and weed pressures (1). Populations of Pseudomonads and other bacteria increase in fumigated soils as soon as 2-wks after treatment (2). Some Pseudomonads can stimulate plant yields through the production of siderophores, growth promoting substances and by the suppression of soil-...

It is truly a priviledge and an honour to be invited to present this inaugural Garrett Lecture, It was also a priviledge and an honour the first time I met Professor S, D, (Denis) Garrett, which was in October 1963, when I was a graduate student at the University of California, Berkeley, under the late W, C, Snyder, Professor Garrett was the invited keynote speaker (Garrett, 1965) at the First ...

The genus Pseudomonas is one of the best-studied bacterial groups in soil, and includes numerous species of environmental interest. Pseudomonas species play key roles in soil, for instance in biological control of soil-borne plant pathogens and in bioremediation of pollutants. A polymerase chain reaction-denaturing gradient gel electrophoresis system that specifically describes the diversity of...

Biological control represents an important approach of agricultural biotechnology for controlling many fungal plant pathogens. Trichoderma spp. are the most promising and effective bioagents against many plant pathogenic fungi. In present paper, two strains of Trichoderma aspellerum isolated from soil were screened for their efficacy against some common soil borne plant pathogens by dual cultur...
