Can Garden Tech Daconil Fungicide Concentrate be used for needle cast?

When should it be applied?


Garden Tech Daconil Fungicide is labeled for needlecast on conifer trees. This is our go to for needlecast.  You should start spraying in spring when new shoots are 1 to 2 inches long. Spray every 3 to 4 weeks until dry weather returns. For Lophodermium Needlecast in Northcentral and Northeastern states: Start spraying in mid-July to early August before disease occurs; spray every 3 to 4 weeks until dry weather returns. Be sure to review the product label page 14 for specific instructions.
