I have a NorthStar 16 gallon, 2.2 GPM, 70 PSI broadcast sprayer. I want to use Tengard to spray my yard (large area) for ants, army worms and other insects.
For Lawns, mix 0.4 to 0.8 fluid ounce of Tengard SFR in 4 to 25 gallons of water per 1,000 square feet.Use the higher rate for fast knockdown and increased residual control. Dense or excessive(greater than 3 inches) lawn height and arid conditions may require higher volume application rates. Repeat application if necessary. Application in combination with compatible surfactants or wetting agents may enhance penetration.
