treatment with metalaxyl

[Guna]

We are growing plants in a gravel bed hydroponic system. They have recently been infected by a
zoosporic strain of Pythium. This requires treatment with metalaxyl, whose field dose is 1.2 kg per
hectare. Does anyone out there know the required dilution for a re-circulating system, so that
phytotoxicity does not occur.

That sounds like a question for my friend Dr. Guna at Fisk U. E-mail him at [email protected]
