CONIFER DISEASES
Apply only to conifers in landscape situations. Apply this product in sufficient water to obtain
uniform coverage of tree canopy, including the undersides of leaves, to the point of spray
runoff. Mix the indicated rate of this product into each 4 gallons of water to be used for each
application, generally sufficient to treat 200 square feet. Do not apply more than 16 fluid ounces
(100 teaspoonfuls) of this product per 1,000 square feet per year on field-grown conifers.
Note: Avoid spraying plants during extremely hot and sunny weather. DO NOT apply this
product within one week before or after application of oil or an oil-based pesticide.
Do not graze treated areas or feed treated plant parts to livestock. Do not use on forests.
tsp. = teaspoonful ( 1/6 fluid ounce) RATE PER 4 GALLONS = 5 tsp. Per Application
Diseases: Scleroderris canker (pines), Swiss needlecast, Sirococcus tip blight,
Rhizosphaera needlecast (spruces), Scirrhia brown spot (pines) Application
Directions: Make the first application in spring when new shoot growth is ½ to 2 inches in length.
Make additional applications at 3 to 4 week intervals until conditions no longer favor disease
development. For use in nursery beds, apply the highest rate specified on a 3 week schedule.
Diseases: Cyclaneusma and Lophodermium needlecasts (pines) Application
Directions: Apply in early spring prior to budbreak. Repeat applications at approximately 6 to 8
week intervals, until spore release ceases in late fall. Apply monthly during periods of frequent rainfall,
and where Lophodermium infections occur during dormancy (Pacific Northwest). During drought
periods, applications may be suspended, then resumed upon next occurrence of needle wetness.
Diseases: Rhabdocline needlecast (Douglas-fir) Application Directions: Apply at budbreak and
repeat at 3 to 4 week intervals until needles are fully elongated and conditions no longer favor
disease development. When irregular budbreak occurs, apply weekly until all trees have broken
bud, then every 3 to 4 weeks as specified above. In nursery beds, apply on a 3 week schedule.
Diseases: Botrytis seedling blight, Phoma twig blight Application Directions: Begin
applications in nursery beds when seedlings are 4 inches tall and when cool, moist
conditions favor disease development. Make additional applications at 7 to 14 day
intervals as long as disease favorable conditions persist.
Diseases: Autoecious needle rust (Weir's cushion rust) (spruces) Application
Directions: Begin applications in nursery beds when 10% of buds have broken and
repeat twice thereafter at 7-10 day intervals.
