| Abstract/Contents: | Assesses the Couch fungicide synergy theory, originally postulated by Dr. Houston Couch, suggesting that fungicides may be used effectively at fractions of their label rates when applied in conjunction with other fungicides. Reports that, in 2008 reassessment studies, "Burpee and Latin did not observe consistent synergistic interactions when they tested the same rates and combinations as Couch did" in the control of dollar spot. Concludes that "we do not recommend using lower than the labeled rates of pesticides" to prevent potential development of dollar spot resistance to fungicides. |
