Dormant Spray Rate Per Litre?
I got my first dormant spray kit today. The label suggests mixing 120ml of lime sulfur and 60ml Horticultural Oil in 3 litre of water.
problem is, how should I set my sprayer dial to allow enough water to pass? assuming 1ml product mixes 1 L of water flow.
should I set the dial to 40:1 (lime sulfur base) or 20 (:1 horticultural oil base) or 30:1 (average of the two)?
Sorry it sounds like some kind of grade 4 math question, maybe my kid would know :)
