NC State Weed Scientist Says Liberty Herbicide Effective when Applied Properly

Today we are visiting with Dr. Wesley Everman, Weed Scientist and Extension Expert with NC State University.

What has been your experience with application of Liberty?
 

“I have had several different seasons to look at Liberty, under a lot of different growing conditions. Across the board we have seen excellent results with Liberty. We just have to time it properly, the right time of day and the right size of weeds, and its an excellent system.”
 

How is it different that glyphosate or other herbicides?
 

“Liberty is different from glyphosate and other systemic or translocated herbicides in the sense that it doesn’t move around the plant. Coverage is essential and you have to have higher carrier volume than you traditionally would in a RoundUp system. You also have to make sure you get the weeds when they are smaller. With a big weed it takes a lot to cover the whole plant and get that control that we want. But with a smaller weed, you can control much easier with the coverage.”

Why is proper application of Liberty important?
 

“Proper application of Liberty is important because we need to make sure we put it out there quickly. If we don’t put it out at the right rate and right size of weed, and right time of day, we can see a reduction in control. So we need to put everything together to give us the best chance to control our weeds.”
 

What are the most important things to remember about the application of Liberty herbicide?
 

“The size of the weeds, you want to get them 3-4” tall and make sure you spray it in the middle of the day, not really early in the morning or late at night. Spray application should be medium to fine droplet size with a little higher carrier.”
 

What has been your level of satisfaction with Liberty?
 

“I have been very satisfied with Liberty. We tend to get out there and make timely applications, and even though we have dry or extra wet conditions, if you get out there on time you will have good control and we have been very happy.”
