Spray herbicide in cold
Can you spray herbicides such as a 3-way mixture in when the weather is still cold? And will it be effective?
These weeds were sprayed at a temp average of about 40 degrees on March 28.
And then at a temperature only slightly warmer of average for the day of 46 on April 7, 2013 .
Weeds were yellow rocket.
Both sprays appeared to work, or at least to result in major distortion and yellowing...so far.
