Chemical and biological control of mushroom pests and diseases.

Abstract

This study set out to determine the occurrence of diseases and pests in Irish mushroom units and their method of control using chemical, biological and other means of control. It also examined the role of a combination of these methods to enable control with minimal pesticide input. It was found that pesticides alone will never give effective disease and pest control and that they should only be considered an adjunct to the implementation of other methods. They include: (1) Exclusion (2) Containment of spread (3) Elimination. A major factor in good disease and pest control was found to be the implementation of a good programme of hygiene which must be followed from the time of filling a tunnel to the time of emptying after cropping. Biological systems offer good potential for control but at present are not as effective as the best chemical control methods.
