I am planning to spray EcoVia EC with a ULV fogger like Vectorfog C100 to sray tall trees and bushes. But the instruction of the EcoVia EC says "For ULV (cold fog) and thermal fog applications, apply undiluted or dilute with light mineral oil or another suitable non-phytotoxic diluent". C100 has a 1-gallon tank and a flow rate of 8-16 GPH, which means it can finish a tank in less than 7.5 min. I just cannot image how much EcoVia EC I would need to treat the area if undiluted or how much oil to spread on trees if diluted. Can we just use water? What is the different between the application with water and oil diluent? Thank you for your help.
In a cold/ULV Fogger, you can dilute concentrates like EcoVia EC with either water or with oil. Typically you would dilute with water whenever possible outdoors to reduce the risk of phytotoxicity on the plants you are treating. Per the product label, use up to 0.25-1.5 fl oz of product per 1000 sq ft of ground surface area, or up to 10-60 fl oz per acre. It sounds like you will likely need to dilute the product to apply at this rate if your fogger is applying product that quickly.
