What is soil drench application rate of Merit 2F (ml per gal) to treat Aphids on Podocarpus 6 feet tall by 50 feet long?
The hedge is about 12 to 18 inches wide.
Typically when treating an evergreen hedge made up of shrubs you would do 0.2 oz of Merit 2F Insecticide per foot of shrub height, so for each individual plant along your hedge that is 6 feet tall you would use 1.2 oz (35 ml) in a sufficient water volume to give a good soil drench coverage. On average you use 5-10 gallons of water per 5 feet of shrub length to ensure the product gets moved into the root zone completely. If for instance you have 2, 6 foot shrubs in a 5 foot length area, you would use 5-10 gallons of water along the root system at the base of the hedge with 2.4 oz (71 ml) of Merit mixed in to that water volume. If you are planning to spray the whole hedge down rather than do a root/soil drench, then the label calls for 1.5 oz per 100 gallons of water.
