The influence of cyprofuram, metalaxyl and aluminiumfosetyl on the respiration of mycelia of Phytophthora cactorum and the sporangia of Plasmopara viticola
1987
Roos, H. (Bonn Univ. (Germany, F.R.). Inst. fuer Pflanzenkrankheiten)
The 200-fold ED50 concentration of cyprofuram (mycelial growth) reduced the mycelial respiration of P. cactorum by 50 per cent while a 14000-fold ED50 concentration of metalaxyl did not significantly influence mycelial respiration. At 200 mug/ml, aluminiumfosetyl completely inhibited mycelial respiration in a shorter time interval with sub-lethal concentrations of aluminiumfosetyl. The reduction of mycelial growth was directly correlated with the reduction in mycelial respiration. A reduction in sporangial respiration of P. viticola could only be demonstrated under the influence of aluminiumfosetyl. A reduction of 86 per cent was recorded after 6 h incubation. This effect was not observed with either cyprofuram or metalaxyl when used at normal field rates
