At least two origins of fungicide resistance in grapevine downy mildew populations.
Quinone outside inhibiting (QoI) fungicides represent one of the most widely used groups of fungicides used to control agriculturally important fungal pathogens. They inhibit the cytochrome bc1 complex of mitochondrial respiration. Soon after their introduction onto the market in 1996, QoI fungicide-resistant isolates were detected in field plant pathogen populations of a large range of species...
متن کاملFungicide Resistance Management
Fungicides are important tools for managing diseases in many crops. Unlike insecticides and some herbicides which kill established insects or weeds, fungicides are most commonly applied to protect healthy plants from infection. To be effective, fungicides must be applied before infections become established and in a sufficient spray volume to achieve thorough coverage of the plant or treated ar...
متن کاملMechanisms and significance of fungicide resistance†
In this review article, we show that occurrence of fungicide resistance is one of the most important issues in modern agriculture. Fungicide resistance may be due to mutations of genes encoding fungicide targets (qualitative fungicide resistance) or to different mechanisms that are induced by sub-lethal fungicide stress. These mechanisms result in different and varying levels of resistance (qua...

Hollomon D.W. (2015): Fungicide resistance: facing the challenge. Plant Protect. Sci., 51: 170–176 Fungicide resistance continues to generate disease control problems in many crops. Experience amassed over the past fifty years has emphasised the importance of diversity in modes of action in anti-resistance strategies. Because of losses, not only from resistance, but increasingly from environmen...

Fungicide resistance in dollar spot caused by Sclerotinia homoeocarpa is a common problem on golf courses in North America (Figure 1) (2), and managing fungicide resistance is a complex and controversial topic (1,4). With dollar spot, the question of whether to use the same fungicide until resistance develops or to rotate different chemistries and tank mixtures has not been defi nitively answer...
