    I am looking to apply some prodiamine to my own yard tomorrow. Its kinda raining off and on throughout today and expected the same tomorrow. Must the ground be completely dry to apply it and how long does it need to remain dry out before it can rain again? Thanks

    Perfect conditions. Pre needs to get into the soil. Light rain or drizzle is fine. Post emergent products typically need to dry.

    prodiamine needs to be watered in with at least .5 inches of water so rainfall after is a must or irrigation. I've applied in slight drizzle with no I'll effects besides me getting wet.

    Thanks. I knew it had to be watered in but i didnt know if there was a time frame that it needed to not rain. I didnt find anything on the label saying such.

    One more thing. Put your rain cap on your spreader. Wet fertilizer does not spread well. It makes a mess.
    Find a way to keep your spreader hopper dry.
    Make a cover out of a fert bag, if you have to.
    Also find a way to keep the bags dry. Remember most plastic bags have holes in them--this is to let the air out so that the bags stack on a pallet easier.

    Huge rain storm headed for the midwest on Feb 19th. Monday.
