Mechanisms of fungicide resistance in phytopathogenic fungi

Current Opinion in Biotechnology, 1996
The disciplines traditionally used to investigate the mode of action of fungicides have been biochemistry and physiology. Over the past decade, classical and molecular genetics have been brought to bear on this problem with increasing success. Recently, genetic studies of fungicide resistance have led to advances in our understanding of the site of ...

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.

Fungicide resistance: definitions and use of terms

EPPO Bulletin, 1985
On the basis of an analysis of current use of terms concerning resistance to fungicides, a series of definitions is proposed for discussion. Consistent use of such terms in scientific publications will facilitate understanding and avoid possible misinterpretations.

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.

Environmental fungicides and triazole resistance in Aspergillus

Pest Management Science, 2013
AbstractFungal diseases are problematic in both human health and agriculture. Treatment options are limited and resistance may emerge. The relatively recent recognition of triazole resistance in Aspergillus fumigatus has prompted questioning of the origin of resistance.

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 ...

Tracking the development of fungicide resistance

2023
This chapter focuses on tracking the development of fungicide resistance. It starts by first providing an overview of the key objectives and requirements in tracking fungicide resistance. The chapter then moves on to review phenotyping tracking of fungicide resistance, which is followed by a discussion on developments in genotyping techniques.

Mechanisms of Resistance to Fungicides

1992
Fungicide resistance is a problem which followed the development of antifungals with specific biochemical modes of action. It is not surprising that the primary mechanism of resistance to these new specific fungicides is target site based. The most characterized example of fungicide resistance based on a modified target is resistance to the ...

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.

Mechanisms of Fungicide Resistance — with Special Reference to Organophosphorus Fungicides

1983
Resistance of plant pathogenic fungi to agricultural fungicides was not important in field practice until about 1970, but it is now an urgent problem in many countries. The resistance problem is mainly due to the recent development and widespread use of new types of fungicides that act more specifically on target fungi and are generally less toxic to ...
