Acquisition of fungicide-resistance by the sensitive strain contact-cultured with dicarboximide fungicide-resistant strains of Botrytis cinerea.

Detection of Botrytis cinerea field isolates with multiple fungicide resistance

Spread of Botrytis cinerea Strains with Multiple Fungicide Resistance in German Horticulture

Botrytis cinerea is a major plant pathogen, causing gray mold rot in a variety of cultures. Repeated fungicide applications are common but have resulted in the development of fungal populations with resistance to one or more fungicides. In this study, we have monitored fungicide resistance frequencies and the occurrence of multiple resistance in Botrytis isolates from raspberries, strawberries,...

Suspension Array for Multiplex Detection of Eight Fungicide-Resistance Related Alleles in Botrytis cinerea

A simple and high-throughput assay to detect fungicide resistance is required for large-scale monitoring of the emergence of resistant strains of Botrytis cinerea. Using suspension array technology performed on a Bio-Plex 200 System, we developed a single-tube allele-specific primer extension assay that can simultaneously detect eight alleles in one reaction. These eight alleles include E198 an...

resistance to qoi fungicide and cytochrome b diversity in the ‎hungarian botrytis cinerea population

quinol oxidation inhibitors (qois) are one of the most important classes of fungicides used in agriculture. they block electron transfer between cytochrome b and cytochrome c1, thereby impeding the production of atp via oxidative phosphorylation. qoi fungicides are generally at high risk of provoking resistance in fungal phytopathogens. resistance has been reported in more than thirty species, ...

Effectiveness of control strategies against Botrytis cinerea in vineyard and evaluation of the residual fungicide concentrations.

This investigation was undertaken to test different control strategies against Botrytis cinerea vineyards. Two commercial vineyards, "Barbera" and "Moscato," located in Piedmont (Northern Italy) were divided into seven plots and treated with different combinations of fungicides including fenhexamid, pyrimethanil, fludioxonil + cyprodinil, iprodione, and boscalid, a new carboxamide compound. An ...
