Urea and crop oil

Unread postby Elite » Thu Jun 25, 2020 5:34 am

Is a crop oil necessary if I intend on spreading urea, or are they used for two completely different purposes?

Different purposes. Crop oil is a surfactant for your herbicide.

Do you mix the crop oil in with the herbicide, like chlethodim?

Yes, but I never worried about using crop oil unless it already comes pre mixed. See the directions on how much to mix if you are going to use it. I don't use chlethodim either. I have never needed it. Glyphoste has always been all I needed.

Read the label on the herbicide you are using. Normally you use spray grade ams in water first to condition water for round up and some other herbicides. 1-3 lbs to the acre depending on how much water spraying per acre. Then surfactant then herbicide. There is a mixing order on label and tells you which surfactant to use for that herbicide. There are quite a few different ones. Nis, crop oil, mso etc.

But for food plots and yard I wouldn't worry too much about adding surfactants. Just get a faster better kill using them. Some are pretty expensive also.

Is crop oil necessary if I don't end up needing an herbicide?

No. Crop oil is for the herbicide to increase it's effectiveness.

Crop oil is an oily subtance to help the herbicide stick to weeds for a better burn down. Crop oil isnt needed just helps it stick. Urea is a dry pelleted fertilizer. I just spread urea on about 2500 acres of corn.
