Last year’s wet weather means farmers will likely be seeing more of a problem with winter annuals.

Making sure your sprayer is ready to go is always key.

Tom Wolf owns Agrimetrix Research and Training and is known to many producers as the “Sprayer Guy.”

He says it’s important to identify the job you want to do with the right nozzles.

"Know what spray quality it produces and what pressure ranges it works at, that's a very fundamental thing we have to remind people. We also want to look to the future, how do you get through a dense canopy with a spray, what do you have to do to do that? Do you use more water volume? Do you use more spray pressure? Our research shows water volume is the probably the single most effective tool to do that."

He says the lentils they've been growing are very difficult to get through with dense canopies.

He also adds the application may vary depending on the area of target and accessibility versus the in-crop canopy.

"Depending on the kind of canopy you have, and this is particularly true for broad-leaf canopies is to use a finer spray. The finer droplets are able to move around obstacles and leaves and make their way further down. When we spray a lentil canopy with quite a coarse spray we find the coarse droplets at the top and only the fine droplets at the bottom, they are the only ones that survive."

Boom height and speed are also important to watch as a higher boom can lead to more spray drift.
