prowl freeze #174235
Asked April 10, 2014, 3:30 AM EDT
Prowl exposed to winter freeze in north mi. [sub zero]...will such deteriorate effectiveness now?...crop is vinifera grapes...last year's planting...prr emergent for weeds..Prowl
Grand Traverse County Michigan
Soil temperatures under the deep snow cover we experienced remained quite warm compared to the sub-zero temps recorded above the snow. Many growers reported to me that the soils never froze this winter due to the heavy snow cover. I would not expect any significant degradation of Prowl's effectiveness due to cold.
Prowl exposure not that applied, but stored in shed from last year and submitted to below zero temps in the bottle and desire to apply soon...remain effective?
I do not know the answer to this question. A product representative from the manufacturer would be able to help you. There may also be information on the label which may provide an answer.
