The possibility of controllina plant-pathogenic fungi by antagonistic micro-organisms added either as a substitue or as an additive to fungicides has been the subject of extensive research. In recent years the increasing use of potentially hazardous fungicides in agriculture has been the subject of arowing concern of both environmentalists and public health authorities. Trichoderma spp. are active as mycoparasites (DENNIS and WEBSTER, 1971). Successful biological control of Sclerotium rolfsii and Rhizoctonia solani by inoculating infested fields with preparation of T. harzianum has already been described by ELAD et al.(1980a). The control of both pathogens in tomatoes, potatoes, beans, peanuts strawberries and carnations also resulted in yield increases (ELAD et al., 1980b, 1981a, 1981c).
We have recently reported the prevention of reinfestation, of methyl-bromide fumigated soil, by S. rolfsii and R. solani (ELAD et al., 1982). Trichoderma was shown to be better established in the fumigated soil than in the non fumigated one. The percentage of S. rolfsii sclerotia parasitized by Trichoderma, was significantly higher in fumigated plots post-treated with the antagonistic preparation. A prolongea effect of methyl-bromide fumigation was found when followed by application of T. harzianum (ELAD et al., 1981b). The effectiveness of coating seeds with the antagonistic fungus was compared in this study with the broadcast application of the preparation into soil. The interactions between T. harzianum and the pathogenic fungi were observed by using infrared photomicrography and scanning electron microscopy, as well as by detecting the enzymatic …
