APPLICATION RECOMMENDATIONS
For use only by certified applicators or those under their immediate supervision. For use on fine turf applications of cool- and warm-season grasses, such as bentgrasses, bermudagrasses, bluegrasses, fescues, ryegrasses, St. Augustine grasses, zoysia grasses or their mixtures, except where prohibited. Spectro® 90 WDG is not phytotoxic to any of the above mentioned grasses when used in accordance with the label. It can provide both curative and protective action. For best results, use spray mixture the same day it is prepared. Spray uniformly over the area to be treated with a properly calibrated power sprayer. Begin applications when conditions favor disease development and repeat applications as long as these conditions persist. Treatments should be applied using 14 – 21 day intervals as indicated. When treating golf greens, always treat aprons and approaches. Use the highest recommended rate and shortest application interval under conditions of severe disease pressure. Apply recommended amounts in sufficient water to obtain thorough coverage (2-4 gallons suggested per 1,000 square feet). Spectro 90 WDG should always be used in conjunction with good turf management practices. Apply after mowing or avoid mowing twelve hours after application. Do not mow or water after treatment until spray deposited on turfgrass is thoroughly dry.
SPECIAL INSTRUCTIONS
Irrigate/syringe lightly (0.1 – 0.25 inches of water) after 8-12 hours. Take care not to move material below root zone of turf in treatment area.
Apply before turf has stopped all growth activity and before snow cover. If snow cover is intermittent or lacking, additional applications may be made at monthly intervals in areas of suspected or historic gray snow mold activity. In areas of predominantly pink snow mold, application should be made during the reproductive (fruiting) period of the pathogen for best results. Consult with your local extension service for this information.

Boxwood Volutella leaf blight
By Thaddeus on 11/06/2020
Verified Purchase
I have hedge lines of many boxwoods. (around 30). I noticed some branches were turning a tan/bronze color. I also saw salmon spores which is a common sign. I did loose some boxwoods, but this really worked well at protecting the parts of the plants that survived and the others around it. I like how it has not just Chlorothalonil, but Thiophanate-methyl as well.

When you are treating blue spruce trees with Clearys Spectro 90 WDG, it is recommended that you spray every 3-4 weeks until the conditions are no longer favorable for disease development. Since this product is a curative, you will use it when the disease appears so this could be at any time of the year.

You would use 1-2 tablespoons pf the Clearys Spectro 90 WDG per gallon of water, and make sure to spray thoroughly as this product is a contact fungicide. You might see a white powdery residue for a dew days, but this will eventually wear off.
