Treating whiteflies on ficus. Not sure if it's measured by weight or my arena measuring cup.
Arena 50 WDG Insecticide states to use 0.9 to 1.26 oz in 100 gallon of water for whiteflies on shrubs. If the product came with a measuring cup, it will always be best to use it. If you do not have the measuring cup, then you will need to go base off weight.
