How long should Trimec be put on before it's rain fast? I put it on my yard to kill dandelions Tuesday night @ 6:00 pm. It's now Wednesday around 11:00 am and threatening to rain. Will it be rain proof yet? Thanks

If you used a spreader/sticker you're probably OK. Ideally you'd give it at least 24 hours, though. Wes

As long as its not a down pour you should still get good results after a couple hours.

Thanks guys. I think I got those darn dandelions they were all curled up this morning so I don't think the rain will have any effect.

What was the temp when you applied? The warmer the air, the quicker it's rainfast.

Sounds like good advice from fellow members. There are several formulations of Trimec, but I assume you used the classic amine formulation.

If temps hit 60 or above, it should be good after 3 or 4 hours because dandelions are easy to kill. Heat , humidity, and sunshine help speed uptake.

We've applied Trimec amine in drizzle on cloudy days and got excellent results - providing temps were 60 or above.

We've also found good results with Mec-Amine D when there's a little rain, especially in dry conditions.

Try telling that to customers though.

The temp was in the mid 70's. I used Trimec Classic. Thanks for all your replies. All the dandelions look like they're done for.

I have finished lawns in a drizzle and been OK. Even a down pour within 1 hour has not hurt results on occasion.

I'm with Grandview on this one.

We would tell the customer to check lawn in one week. If bad control we retreat.

Almost never happens. The possible damage from overdosing with a retreat is not worth the chance.

If you've ever tried to wash herbicide off a plant you accidentally sprayed you know it's pretty tough to do without the herbicide doing some damage. Rain shouldn't make much of a difference once the herbicide is dry.
