Do not make consecutive applications with another FRAC 3-containing fungicide.  REI is 24 hrs for girdling and turning of canes in table and raisin grapes. Recommended 24 hr REI for hand-labor in wine grapes.

Tetraconazole is a systemic, protectant and curative (within a few days of infection) fungicide and is absorbed quickly into the plant tissue.

Apply METTLE 125 ME at 5 fl oz/A using a final spray volume of 25 to 50 gallons water per acre to protect against grapevine pruning diseases caused by Botryosphaeria spp., Eutypa lata, Phaeoacremonium aleophilum, Phaeomoniella chlamydospora. An adjuvant may be used to increase penetration into the pruned wood surfaces. Apply METTLE 125 ME within 24 hours of pruning.
