The active ingredients differ in Clearys 3336F Fungicide vs. the active ingredients contained in Copper Fungicides. You should refer to each product label to confirm that the specific disease you are targeting is listed on that label and for complete application instructions.
It is recommended to mow 2 days prior to or waiting 2 days after after application of Clearys 3336F Fungicide to ensure proper absorption of the fungicide.
For best results, mowing should be delayed for 12 hours before applying 3336F Fungicide or for 12 hours after the application.
Clearys 3336F can be applied to established turfgrass and listed ornamentals for the listed diseases on the label as directed.
3336F Fungicide is labeled for Cercospora Needle Blight/Leaf Spot at the rate of 12-16 fl oz per 100 gallons of water. For smaller volume applications, this would break down to 0.75 to 1 fl oz per gallon of water.
For foliar spray applications, treatments should begin when first signs of the diease are present and repeat at 7-14 day intervals during the season. Use at the higher rate at shorter retreatment intervals when disease pressure is high.
Please view the product label for additional information.
For active lawn diseases, best results are going to be treating with 2 different class fungicides in 14-28 day interval rotation for 2-3 applications then rotating to the other fungicide for the same 14-28 day intervals for 2-3 applications.
Clearys 3336F Fungicide is a Group 1 Fungicide and Eagle 20EW is a Group 11 Fungicide. Please view our Lawn Care Guide for some of the most common Lawn Diseases and Guides for more information and treatment recommendations.
You could potentially mix Clearys 3336F Fungicide with an Azoxystrobin product; however, usually those fungicides would be used in rotation instead of mixed together to help avoid disease resistance. If you would like to tell us more about your application, then we are happy to give a more detailed recommendation.
Depending on the disease you are targeting, excessive irrigation/rainfall may move the application of 3336F Fungicide below the root zone and reduce the effectiveness of the treatment. We recommend waiting at least 7 days to reapply the fungicide if there was rainfall immediately following the application and be sure to have atleast 24 hrs following the application before rainfall is expected.
The only exception with Clearys 3336F would be if you are targeting root pathogens (diseases) where the product label recommends additional light watering (1/10th to 2/10th’s inch of water) to move the active ingredient into the root zone.
3336F Fungicide is applied with sufficent water at the time of application with no rainfall/irrigation with 24 hours of the application. Per the label only specific diseases require watering in after application so in general it is not needed. You should not apply more fungicide to the area before the interval timing listed on the label per area.
While Clearys 3336F Fungicide does not list your specific plant on the product label, it is generally safe to use on most ornamentals. We encourage you to have the problem identified before applying fungicides so that you can apply the best product for the disease, if there is one. Ixora are acid-loving plants, so be sure you are pruning properly and using fertilizer specific for acid-loving plants, such as FoxFarm Happy Frog Acid Loving Plants Organic Fertilizer (6-4-4).
Clearys 3336F Fungicide is not labeled to treat for Volutella Blight. Cupro 5000 would be a better option to treat for Volutella Blight on Pachysandra.
Clearys 3336F Fungicide is not labeled for leaf blotch. We would recommend a product such as Garden Tech Daconil Fungicide Concentrate instead, which is specifically labeled for leaf blotch.
Clearys 3336F Fungicide is a fungicide (not insecticide) that should be applied when the bees are not foraging to avoid contact with the product.
Please provide the targed fungus/disease so that we can offer the proper dilution/application instructions. Thank you!
Clearys 3336F Fungicide can be applied as a foliar application or a soil drench application for a maple tree. If doing a foliar application it would be applied at 12-16 ounces of product into 100 gallons of water and sprayed all over the canopy and bark. If doing a soil drench application it would be applied at 8-16 ounces of product into 100 gallons of water and poured around the trunk avoiding the drip line.
Per the Clearys 3336F Fungicide label, page 6: Apply material with properly calibrated hand held, mechanical or motorized spray equipment or by chemigation through appropriate sprinkler irrigation,flood,or drip systems. Begin applications when disease first appears and repeat at 7-14 day intervals or as needed during the growing season. Use the shortest interval when conditions are unusually favorable for the development of disease
Clearys 3336F Fungicide is only labeled to treat rusts on ninebarks. Powdery mildew on ninebarks doesn’t appear to harm them it is more aesthetic. A horticultural oil would be good to use.
