There are 24 million acres of native and tame pasture and range as well as 1.4 million acres of grass hayland in South Dakota.
With the rise of herbicide-resistant weeds, the use of an adjuvants is also on the rise and may be necessary to help control resistant weeds.
Noxious Weed Recommendations: Herbicides for pasture, range, and non-crop areas, including roadside and other right-of-way that may be harvested for hay or grazed, are given a priority.
Producers need to plan in advance on how to deal with bare fields that contain an overabundance of weeds. Weeds in these fields have deposited significant amount of seeds on the soil surface, which can easily germinate when adequate moisture and temperature are available.
The warmer weather and spring migration this March have us all thinking of better days ahead. Unfortunately, it also has us thinking about flooding again this spring.

In South Dakota, the spring can come with a wide range of temperature fluctuations. This will affect the performance of burndown herbicides. Depending upon the target weed, type of herbicide and application rate, there will likely be decreased weed control in cooler temperatures.
The goals of applying any crop protection products include: increasing effectiveness, mitigating drift, and maximizing profits. We will focus on mitigating drift, even though all three interact with each other.
