ABSTRACT
The ability of Trichoderma and Gliocladium species to control plant disease and enhance plant growth has been known for many years. The first major discoveries were made by Richard Weindling in the 1930s and 1940s. He made a number of discoveries that have provided much of the impetus for basic and applied research on the biocontrol abilities of these fungi ever since. Among the contributions that Weindling made are the following:
1 T . lignorum (this taxon was changed to G. virens, and now is considered to be T . virens (Bissett, 1991)) parasitizes hyphae of plant pathogenic fungi in two ways, i.e., by coiling about them and by killing at a short distance away (Weindling, 1932) (see Chapter 7 for the current status of this topic).
