Tropical Fruit Discussion / Re: Cosavet DF Edge Sulfur for Powdery Mildew
« on: December 16, 2019, 01:42:43 PM »I typically interpret the per acre rate as 100 gallons. I checked the label and it specifies "dilute" application as 100 - 800 gallons per acre and "concentrate" application as 20 - 100. So, I would probably go with the 100 rate.
Try to stay away from tender foliage, especially that of Lemon Zest, as it can burn. Also, try to apply in the evening or during cool weather.I recently bought Cosavet DF Edge (80 percent sulfur) for spraying my mango trees during cold spells. It is a OMRI listed fungicide-miticide that is water dispersible and flowable. I was able to mix it with water and spray with my 2 gallon sprayer.
Have a question for the experts. How much sulfur is too much sulfur when spraying? Can too much sulfur impact fruit set? The label says 10 to 30 lbs per acre, but that is of no use for growers like us.
So is the consensus 3tbsp per gallon or 4tbsp per gallon? Thanks.
