Rust on gerberas

I AM having a lot of trouble with white rust on my gerberas. I have picked the infected leaves off three times now and sprayed them twice with Greenguard. It is back again. What do I have to do to get rid of it?


GERBERAS make a great show in the garden but can suffer from lots of problems, like white rust. A general fungicide should do the trick. You will need to spray continually throughout the season as the rust will not be controlled in a couple of sprays. Keep going with the Greenguard, or alternate with Yates Fungus Fighter, Shield or Super Shield. The advantage with using either Shield or Super Shield is that they also contain an insecticide so you can do two jobs in one if you also have insect pests around the plants.
