Directions and Usage

Apply in solution at the rate of 1 pound in 5 to 20 gallons of water. Apply in early morning or late afternoon, avoiding periods of heavy direct sunlight. For best results, premix the required amount in water prior to adding to the spray tank or concentrate tank. This material dissolves faster in warm water. It gives off an endothermic reaction (turns icy cold) when it is being dissolved. See product label for specific use rates.
