| Abstract/Contents: | Discusses potential alternatives to fungicide treatment of turf diseases. Explains that "over-reliance on one or several fungicides, particularly those that attack a single site in fungal cells, has resulted in control failures due to declining sensitivity or resistance in some plant pathogenic fungi." Lists fungicide classes that may be at risk for resistance, including benzimidazole, phenylamide, strobilurin, dicarboximide, DMI, phosphonate, phosphorous acid, and carbamate. Mentions the possibility of cross-resistance between fungicides. Explains that "resistance to one dicarboximide or DMI fungicide almost always results in cross-resistance with other fungicides that have the same mode of action." Discusses potential methods for reducing and avoiding resistance to fungicides, stating that "resistance to fungicides that attack multiple sites in a fungal cell is rare." States that "fungicide control failures not always can be blamed on resistance. They are often caused by other factors relating to the time of disease identification and onset; weather patterns; fungicide specificity and placement; application rate and timeliness; residual activity in the target zone; and a variety of cultural practices." Suggests monitoring "the success of...disease management programs that employ at-risk fungicides and report suspected resistance to [the state] extension plant pathologist." |
