All stages of street improvement - from development and use by way of autos to upkeep - have an effect on actual and chemical soil stipulations, water circulation, and air and water caliber, in addition to vegetation and animals. Roads and site visitors can adjust flora and fauna habitat, reason vehicle-related mortality, hamper animal migration, and disperse nonnative pest species of crops and animals.

Some progress, however, has been made in this direction. Volatile inhibitors from soil which have been implicated in mycostasis are CO 2, ammonia, ethylene, and sulfur compounds. A comprehensive review of the effects of O 2 and CO 2 on the growth and metabolism of fungi has been published (Tabak and Cooke, 1968). In addition, Griffin (1972) discusses many aspects of CO 2 chemistry in soil in relation to fungal growth. Nonvolatile substances exhibiting antifungal effects which have been identified in soil include metals and salts, nitrous acid, molecular-sieve fractions of soilleachates, and aromatic compounds from leaf litter and detritus.
C. lunata. and T. basicola and suggest that microbial competition for nutrients might be the causal mechanism for the foliar mycostasis (Sztejnberg and Blakeman, 1973). Mycostasis of B. cinerea conidia was closely related to microbial competition for amino acids. A common leaf saprophytic bacterium, Pseudomonas sp. isolate 14, competed very actively for amino acids in glucose-amino acid mixtures and removed 80% from solutions in 5 hr (Brodie and Blakeman, 1976). Inhibition of conidial germination was closely correlated with amino acid uptake by this bacterium.
1965; Ballesta and Alexander, 1972). Lysis, to varying extents, of killed conidia by wall-degrading enzyme preparations and by soil also has been observed (Chu and Alexander, 1972). , 1965; Bloomfield and Alexander, 1967). Unfortunately, the question has not been addressed experimentally to the extent that is merited. , 1965), but this cannot be taken as evidence for heterolysis, since induced autolysis is not ruled out. , 1963; Garcia Mendoza and Villanueva, 1962, 1964) incubated in crude enzyme prep- John L.
