Paphs - brown rot issues

[mauraec]

I rotate these fungicides around; Manzate, Captan (both in powder form) and a systemic liquid type (don't know what it is - name and instructions all in Thai but very effective). I spray about once every 2 months or so. Remember I grow my orchids outdoors 24/7 and exposed to the rains that tend to leach out chemicals and fertilisers pretty fast. Thus the high frequency of application.

Thank you - I'll look for those. (But not the Thai liquid!)
