Time Between Applications
Prodiamine can be split between two applications. I generally like to do a split application. That means I will apply half of the total rate for the amount of months I want coverage at 55°F soil temperature and half of the total rate at 70°F soil temperature.
Weed control is most effective when Prodiamine 65WDG is activated by at least 0.5 inches of rainfall or irrigation or shallow incorporation (1 to 2 inches) before weed seeds germinate and within 14 days following application.
Before Seeding Instructions
Don't apply Prodiamine if you plan on seeding, otherwise, wait until the pre-emergent barrier wears off based on your application rate in the "Interval (Months) Before Overseeding" table in the label. It is non-selective and will kill any seed that is trying to germinate, including desirable turfgrass.
After Seeding Instructions
To reduce the potential to injure overseeded turf, wait 60 days after seeding or until after the second mowing, whichever is longer, before applying Prodiamine 65WDG.
Do not use a surfactant.
