Re: CULT: Terrachlor and rots

Rick Tasco, speaking of "southern blight" or "mustard seed fungus", a
devasating condition caused by a soil-borne fungus requested information
thus:

 mason-dixon line and above let me know if you ever experienced this.      >>

This is a pretty distinctive blight. I have had it in those areas of my yard
where the soil is poor and compacted, shady and sodden, with poor air
circulation. It carried off a patch of asarum and periodically attacks some
hostas. Especially lethal to species aquilegias. I have not had this on
bearded irises, athough I lost a setosa to it. Terraclor, a very elegant
chemical, knocks it out. That is all that knocks it out. I use it as a soil
drench, both to cure and as a prophylactic treatment in garden areas at risk.
The fungus doesn't go away by itself, although it will go dormant, producing
the characteristic fruiting bodies like mustard seeds which are visible on
the soil surface. The disease can remain in the soil for many years in a
dormant state.

I am reliably informed by a member of the local professional horticultural
community that using Terraclor two years running on an area can stunt some
perennial plants.

We took a ride last evening and the tree frogs were peeping in the ditches.
Spring!
