FUNGICIDES: Mixing Mix Benlate with Dexon; mix Benlate with Truban; do not combine Dexon with Truban because they both do the same thing; Dexon is stable only one or two days in water; the others somewhat longer. A74-792 0

FUNGICIDES: Weekly Spray for Brown Spot on Cattleyas Weekly spray with Physan (Captan 50%) plus intermittently with Natriphene is far too much and could cause the spotting. A75-618 0
