Rotational Crops: Treated areas may be replanted with any crop specified on this label as soon as practical after last application. Any crop not specified on this label may be planted into treated areas 120 days after last application.

Spray Volume: Apply by ground in a minimum of 10 gallons of spray solution per acre or by air in a minimum of 5 gallons of spray solution per acre. Check equipment calibration frequently. For best disease control, complete coverage and uniform application are essential, especially when lower spray volumes are used. Use the appropriate spray volume to ensure complete coverage.


ASPARAGUS - Rust (Puccinia spp.): 4 to 6 fl. oz. per acre

Application Directions:

Applications may be made using ground or aerial application equipment. For optimum disease control, the lowest labeled rate of spray surfactant should be tank-mixed with Tebuzol 3.6F. Tebuzol 3.6F is a sterol demethylation inhibitor (DMI) fungicide (Group3). Alternating Tebuzol 3.6F with other DMI fungicides may lead to resistance.

Apply Tebuzol 3.6F as a foliar spray to the developing ferns after harvest of spears is completed. Apply at the earliest sign of rust pustules or when weather conditions are conducive for rust development.

Apply 4 to 6 fl. oz. of Tebuzol 3.6F per acre (0.11 lbs. a.i. - 0.17 lbs. a.i. per acre) in alternation with another effective fungicide. Under conditions of severe rust pressure, use the higher rate. Repeat applications on a 14-day interval as necessary to maintain control of rust.


  • Do not apply to harvestable spears.
  • Do not apply within 100 days of harvest in California and 180 days in all other states.
  • Do not make more than three foliar applications per season (18 fl. oz./acre or 0.51 lbs. a.i./acre).
  • A 50-foot spray drift buffer zone is required for all aerial applications.
  • Restricted-entry interval (REI) = 12 hours

DRY BULB ONION, GARLIC, GREAT-HEADED (ELEPHANT) GARLIC, WELCH ONION, SHALLOT -White Rot: 20.5 fl. oz. per acre applied in a 4 to 6 inch band over/into each furrow. May be applied by chemigation to control white rot. Rust (Puccinia allii, Puccinia porri) Purple blotch (Alternaria porri): 4 to 6 fl. oz. per acre.

Application Directions:

White rot: For the control of white rot, make one application in the furrow at the time of planting. The in-furrow application may be made at the rate of 20.5 fl. oz. Tebuzol 3.6F per acre. Apply the entire per acre rate in a 4 to 6 inch band over/into each furrow. Additional control may be obtained by including two foliar applications at 4 to 6 fl. oz./acre.

Rust: For the control of rust make foliar applications at the rate of 4 to 6 fl. oz. Tebuzol 3.6F per acre per application. Repeat at 10- to 14- day intervals. Apply Tebuzol 3.6F in a protective spray schedule or when weather conditions are favorable for rust development.

For optimum results use as a preventative treatment. Begin applications as soon as crop and/or environmental conditions become favorable for disease development. The lowest recommended rate of a spray surfactant may be tank-mixed with Tebuzol 3.6F. Tebuzol 3.6F must have two to four hours of drying time on foliage for the active ingredient to move systemically into plant tissue before rain or irrigation occurs. After this period of time, Tebuzol 3.6F will be resistant to weathering. Tebuzol 3.6F is a demethylation inhibitor (DMI) fungicide (Group 3).

*Not for use in New York.


  • Do not apply more than 32.5 fl. oz. Tebuzol 3.6F per acre per season if an in-furrow treatment is made.
  • If Tebuzol 3.6F is not applied as an infurrow treatment then do not apply more than 12 fl. oz. Tebuzol 3.6F per acre per season as a foliar spray.
  • Do not apply within 7 days of harvest.
  • Restricted-entry interval (REI) = 12 hours



This pesticide is toxic to mammals, fish and aquatic invertebrates. Do not apply directly to water, or to areas where surface water is present or to intertidal areas below the mean high water mark. Runoff may be hazardous to aquatic organisms in neighboring areas. Do not contaminate water when disposing of equipment washwater or rinsate.

Ground Water Advisory: Tebuconazole is known to leach through soil into the ground under certain conditions as a result of label use. Use of this chemical in areas where soils are permeable, particularly where the water table is shallow, may result in ground-water contamination.

Surface Water Advisory: This product may contaminate water through drift of spray in wind. This product has a high potential for runoff for several months or more after application. Poorly draining soils and soils with shallow water tables are more prone to runoff that contains this product. A level, well maintained vegetative buffer strip between areas to which this product is applied and surface water features such as ponds, streams, and springs will reduce the potential for contamination of water from rainfall-runoff. Runoff of this product will be reduced by avoiding applications when rainfall is forecasted within 48 hours.
