Prime Source Azoxy 50 WDG Fungicide and Strobe 50 WG are essentially the same product, just made by different manufacturers. They both contain Azoxystrobin at 50% and are labeld for all the same target pests.
Prime Source Azoxy 50 WDG Fungicide 1 lb jug is 16 oz.
Prime Source Azoxy 50 WDG Fungicide must be mixed with water and applied as a liquid solution. It does not need to be irrigated further after the application has been made unless the product label states to do so for the specific disease you are targting. We recommend to hold any lawn watering for the next 24 hours at least.
Prime Source Azoxy 50 WDG Fungicide is mixed at 0.4 oz to 0.8 oz per gallon of water for rose blackspot every 7-14 days.
Prime Source Azoxy 50 WDG Fungicide does not control or prevent dollar spot, per the product label. You would need to use an additional or alternate fungicide to treat dollar spot, such as Ferti-Lome F Stop Lawn Fungicide Granules or Fame Granular Fungicide. We have more tips in our Dollar Spot Treatment Guide as well.
It is not recommended to apply Prime Source Azoxy 50 WDG Fungicide with a hose end applicator as it is hard to regulate the water volume being used. For best results, it is recommended to use a pressurized handpump or backpack sprayer to ensure a sufficient amount of water is being used evenly per 1000 sq ft.
