How to Stop Drift

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.

Temperature and Herbicide Performance

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.

Preparing Spray Solutions: Mixing Order

Before mixing any pesticide always check the pesticide label for instructions on compatibility of two or more pesticides. Some herbicides and carriers require a compatibility agent, some are not compatible with a compatibility agent.
