Spray Nozzle Questions


what kind of spray nozzles you should use during this spray season? Here are some questions you should
first ask.

• Are you using more highly active or nonselective herbicides?

• Are you planting more herbicide-resistant crops?

• Are you able to apply pesticides at the right crop growth
stage? Or do you need a wider window in which to spray?

• Are there sensitive areas (shelterbelts, neighboring fields,
rural homes) close by that you should protect from drift?

• Are you
concerned about the effect of pesticide drift on the environment?

• Are you
trying to avoid future drift problems?
