Abstract/Contents:Discusses the development of fungicides belonging to the strobilurin group that "are chemically related to natural compounds produced by specific mushroom and toadstool fungi that colonise [colonize] pine cones." Explains that "these natural compounds are produced by one group of fungi to stop competition from others, so closely related synthetic chemicals will clearly have a fundamentally 'natural' fungicide pedigree." Profiles azoxystrobin, pyraclostrobin, and trifloxystrobin. States that "azoxystrobin is the active ingredient of 'Heritage'... Azoxystrobin is synthetically derived from strobilurins naturally occuring fungicides produced by particular species of wood-decaying mushroom and toadstool fungi...Pyraclostrobin is a second generation strobilurin fungicide and the active ingredient of 'Insignia'...Pyraclostrobin is classified as a methoxycarbamate strobilurin type fungicide...Trifloxystrobin is the active ingredient of 'Scorpio'...[and is] classified as an oximinoacetate strobilurin type fungicide." Explains that "long term confidence in fungicide management is paramount for users and manufacturers alike...Fungicide resistance is caused by inappropriate use of a single fungicide or several fungicides with the same mode of action." Suggests application methods for strobilurin fungicides, stating that "strobilurin-type fungicides are potentially vulnerable to fungicide resistance. The active ingredient inhibits mitochondrial respiration by blocking electron transfer between cytochrome b and cytochrome c1 at the ubiquinol oxidising [oxidizing] site thus demonstrating a highly specific single-site mode of action." Concludes that "an important part of active resistance management strategies is to ensure the strobilurins are not used exclusively, but alternated as recommended with a fungicide from another group having a completely different mode of action."
