Grower Resource: Herbicides and Spray Drift

BY David Schiff | February 1, 2017 - 

Though a blanket of snow covers the fields now, it won’t be long before you’ll be thinking herbicides and spray drift. Here are a couple of handy resources to help.

The first, a cheat sheet on herbicides, helps you figure out the best plan of attack without creating herbicide resistance. Using weed appropriate, different and multiple modes of herbicide action is the best path to decrease the risk of resistance.

You can find more information about defeating herbicide resistance at

The second resource, a one page guide to reducing spray drift, gives you the four key factors to reduce spray drift:

  1. Nozzle selection—How to ready nozzles and find direction to calibrate them
  2. Droplet size—How the size of the droplet affects the chance of drift
  3. Application speeds—How speed and drift are related
  4. Additional considerations—Extra steps you can take, such as using drift-reduction nozzles, to control drift.

Again, you’ll also find more information about controlling spray drift at
