According to the product label of Drexel Imitator Plus, "Do not apply to vegetation in or around ditches, canals or ponds containing water to be used for irrigation." The label also states, "Remove domestic livestock before application and wait 8 weeks after application before grazing or harvesting." Please be sure to review the full product label for more information and complete application instructions. If you are treating an irrigation area, you will need to use a product specifically labeled for aquatic use.
It is recommended when applying Drexel Imitator Plus, or any herbicide, that you use it only when soil temperatures are 55 degrees or higher consistently. If soil temperatures are all over the place due to weather fluctuations as we are coming out of winter and into spring, then you may see spotty results, or may want to wait until further into the season when temperatures are higher.
You can use from 0.5 to 13 oz per gallon when using the Drexel Imitator Plus. Lower rates will be for smaller annual weeds, and higher rates are for more difficult plants like woody plants and vines. It is non-selective, so it will kill anything sprayed directly per the product label instructions.
