So we would like to spray the field trial with a selective fungicide, which kills the powdery mildew, but does not affect the rust. Till recently we used MILGO-E (ICI, Rotterdam) for this purpose. The active compound is ethirinol 28%. However, this fungicide is not available anymore. I am very much interested whether anybody can suggest other chemicals to achieve our goals. I would be interested also in experimental data on the (lack of) effect of mildew-fungicides on rust fungi. Thanking you very much for your advice in this matter, Rients Niks From BIOSCI-REQUEST Wed Jul 12 15:37:11 1995 Return-Path: BIOSCI-REQUEST Received: (from daemon@localhost) by net.bio.net (8.6.12/8.6.6) id PAA27330 for rust-mil-list; Wed, 12 Jul 1995 15:37:11 -0700 Received: from morgan.angis.su.OZ.AU (morgan.angis.su.OZ.AU [129.78.25.38]) by net.bio.net (8.6.12/8.6.6) with ESMTP id PAA27327 for ; Wed, 12 Jul 1995 15:37:07 -0700 Received: (from pbic00@localhost) by morgan.angis.su.OZ.AU (8.6.10/8.6.6) id IAA11036 for Rust-mil@net.bio.net; Thu, 13 Jul 1995 08:35:22 +1000 Date: Thu, 13 Jul 1995 08:35:22 +1000 From: "Plant Breeding Inst."

We have not attempted field experiments, but for greenhouse studies we are attempting to use Bayleton¨ or Tilt¨ to control early mildew infections prior to rust infections for adult plant studies. The assumptions are that there is loss of effectiveness with time (3-6 weeks depending on concentration) and that being located on the leaf surface, mildew is more sensitive than rusts. We have had varied success with the procedure. Perhaps there are some useful research results.

You could therefore try one of these fungicides (tridemorph, fenpropimorph or fenpropidin) at a low rate. I suggest that you do a pilot experiment before committing yourself to choosing one fungicide for your entire trial.
