Spraying Early

We’re a custom application outfit and this year, for some reason, we’ve had a ton of customers ask us not to start spraying till the dew has dried… just wondering what everyone’s thoughts and opinions where on that? Been in business for 25 years and never had a problem spraying early so we are at a lost to why everyone is concerned all of the sudden? 🤷🏼‍♂️

Most of the dew goes right back into the plant on a warm morning, I've seen articles that claim a little dew enhances the chemical. Same guys that are screaming about using 20 gallon of water are probably the ones worried about the dew!!

I get concerned about the dew here when it's really heavy in early July, but sometimes we just have to go when we can. Often times that means before it starts to get windy at 9 AM. I might throw in some extra AMS or crop oil if I'm too worried about it. I'd rather spray on the early morning dew then after it gets dark in the evenings.

i prefer to spray with a small amount of dew, my theory is the plant is softer under moist conditions and hangs on better, is use 20 gallon rate and never had an issue, when I spray in the heat of the day seems it drys way too fast

KInda hard when you have a lot of acres to cover and they want to pick the times they better buy a sprayer. I know you want to keep the customers happy but there is only so much time in a day and wind usually starts to make the days smaller

In my part of the world (eastern Dakotas / western Minnesota) we have had discussions when we are in a weather pattern that’s blowing a lot of moist air up from the gulf. That extremely wet leaves in the morning will almost act like rain on a sprayed crop. So it theoretically wouldn’t allow your spray to stay on the surface of the leaf.

However, if we sat and waited for the dew to come off in our...

Hey Evan, I'm the agronomist for FBN for the upper midwest region. So, I'm not going to have an unbiased answer. I would ask you to look at our Farmers First line of adjuvants.

The two call outs I will make regardless of what brand and company you source from.


1) do they have a lot of products that are CPDA certified? Having that certification doesn't guarantee that it is better than an adjuva...

Any brand of surfactant you'd recommend? We're starting to do more of our own spraying now that we've got a self propelled rig, and I've got a lot to learn yet.
