Field ecology of the ochratoxin A producing Penicillium verrucosum:Survival and resource colonisation in soil.

The survival of Penicillium verrucosum and indigenous soil fungi in soil containing waste grain was evaluated for the period October 1994 to March 1996. P, verrucosum while its abundance in bulk soil was more constant. In the soil plus waste grain sample, P. verrucosum initially infected more than 50% of the kernels but during the first few months it was ousted by other fungi. A hypothesis regarding waste grain as the natural niche for the fungus in the field was therefore partly rejected. A gradual decrease in the abundance of P. verrucosum in soil during spring, a die-odd in the second winter were found in both samples.
