Pesticide use and mycotoxin production in fusarium and Aspergillus phytopathogens.

The major mycotoxigenic species of fusarium and Aspergillus phytopathogens are identified in this review with 48 references. Since fungicides are widely used to contro crop diseases caused by these fungi, their efficacy with respect to mycotoxin production needs to be considered. In both laboratory studies with pure cultures and field trials with crop plants, the overall evidence concerning the effectiveness of fungicides is contradictory and in certain cases somewhat unexpected. In particular, at sub-lethal doses of a number of fungicides including carbendazim, tridemorph, difenoconazole and tebuconazole with triadimenol, mycotoxin production from fusarium  phytopathogens may increas. The limited evidence on the effects in Aspergillus species is also conflicting. Under laboratory conditions, miconazole and fenpropimorph have been shown to increase aflatoxin production from A. parasiticus. Since fungal infection of plant products is often preceded by insect damage, there is interest in the effectiveness of insecticides to reduce infestation, infection and mycotoxin contamination.
