Can I apply Prodiamine WDG with a hose-end sprayer?

The simple answer is NO and this is because the exact rate of application cannot be controlled as easily with a hose-end sprayer.  

We recommend using a pump sprayer or battery-powered hand can for any type of herbicide, insecticide, or fungicide and following all label instructions.  

Here is a how to video of Allyn demonstrating how we recommend applying Prodiamine WDG:
