I know its not the best time of year to be spraying a 3 way herbicide, but a gentleman wanted his 2 acre lawn sprayed as weeds were getting out of control. So this afternoon I sprayed entire 2 acre lawn and about 1 to 2 hours later a pop up thunderstorm came rolling through and dumped only 15 hundredths of rain. Will the chemical work or will I need to re spray, and if I do need to re spray would you do it at no cost??

I had a pop up downpour cell on a lawn literally 15 minutes after I sprayed 3 way with a sticker. Almost complete broadleaf kill (brand new client, neglected yard.) so yes, you'll be fine

Raymond said the right thing...with a sticker.
If you added a Surfactant I would go look early next week and determine your results and post them.
I have the same happen often. Sometimes I have to retreat....other times not.
What I find surprising is at times I expect a low control and get a high control, other times the opposite.

In my experiments 60 minutes before rain was marginal, but rain after 150 minutes had no effect --no reduction in weed control.

I think you will be fine. I would not do it over again--(free) unless he is a regular customer getting continuing treatments.
If he wants it done over for free--he should have rain insurance or have such a feature written into the contract or oral agreement.
The idea that a "spreader sticker" will speed up intake or reduce the effects of rain is probably salesman's hype.
But I hope to test the idea .

Is this the one you mean?

It has a low use rate, about one-tenth of one percent in the spray solution in the tank.
Still, I would like to see proof that it works to reduce the rain effects on weed control.

Yeah that's the one except my label is blue, not green. Proof? It's all I've use the last 15 yrs and haven't had to respray after a rain. I've sprayed as I saw the storm coming on the radar. Wait for the 15 mark, then leave. Weeds are dead/dying when I come back a few days later. Anecdotal I know, but all I need.

Happens to me all the time, I've even sprayed in a light drizzle and still had almost no impact on efficacy. I always use lesco spreader sticker which is a Non ionic also, except with a few different products that recommend no sticker.
