Fungicide resistance risk assessment

2023
New fungicide active substances are at risk of losing efficacy due to the development of resistance in target pathogen populations. In the European Union, an assessment of resistance risk is required by regulatory authorities for the approval of each fungicide product This chapter will review the development and scientific rationale of the widely used ...

The fungicide-resistance problem

Netherlands Journal of Plant Pathology, 1977
Mutation to resistance is more likely to occur to systemic fungicides than to conventional fungicides. The possibilities to obtain systemic fungicides, to which fungi will not readily become resistant, are discussed. A high potential for development of fungicide resistance does, however, not always imply that problems will arise in practice.

Apple Scab: Resistance to Chemical Fungicides

Biology Bulletin Reviews
The review highlights the situation with the development of resistance to various systemic fungicides in Venturia inaequalis around the world and in Russia, with an assessment of the prospects for their further use. Information is provided on all fungicides used in Russia against apple scab, their effectiveness at a given time, and a description of ...

Industry's response to fungicide resistance

Crop Protection, 1984
Abstract Industry's response to reports of fungicide resistance has varied from denial to a leadership role in defining the problem and implementing solutions. Individual isolated company activities now find co-operative support in an emerging inter-industry organization called the Fungicide Resistance Action Committee.

Mechanism of Resistance to Fungicides

1997
Fungicide resistance has been reported from well over 300 fungi, although the vast majority of these cases involve laboratory-resistant mutants, rather than fungi isolated from field crops. So far, only in some 25 plant pathogens has resistance become a serious practical problem.

The Problem of Fungicide Resistance

BioScience, 1969
The effectiveness of poisonous substances often decreases after they have been in use for some time. This phenomenon, which was apparently known to Theophrastes (Inquiry into Plants, Book IX, Chapter XVI), has caused considerable difficulty to modern man in his efforts to control harmful organisms by the use of toxic compounds.
