Jeff from Heber, Ar writes,
Why would you buy 1.4% concentration instead of using a smaller amount of the 5% solution?
Different concentrations are labeled for different types of pests, applications, places to be applied, etc. For example PyGanic Crop Protection EC 1.4 is labeld to be used in greenhouses and outdoors on crops and ornamentals. Evergreen Pyrethrum Concentrate is labeled to be used in homes, barns, food handling areas, etc.
