I see the ratio for apples is: "Use 1 - 2 gal per 100 gal of water at 100 - 800 gal per acre. (Concentrate Spray: Use 3 - 8 gal per acre in a minimum of 20 - 100 gal water per acre.)" I will need ~20 gallons of water to spray my apple trees. Will I really need 3 gallons of spray for 20 gallons of water? Is this ratio on the label for commercial sprayers?
The product label for the Ultra-Pure Oil Horticultural Insecticide, Miticide and Fungicide will give rates per Acre since it is designed for commercial applications. If you are treating a smaller area, than you would need to calculate the correct amount of concentrate for the area that you need to treat, and then use sufficient water for your application. If you only have a few trees to treat, we do sell several other horticultural oils that may be easier to measure. Monterey Horticultural Oil comes in several different sizes, and you would use 2.5 to 5 ounces per gallon of water to treat Apples.
