New Insecticide Registration

A new insecticide is now available for use on home lawns to control insects such as Chinch Bug, Ants, and Sodweb worm. DeltaGard , is a third generation synthetic pyrethroid that in addition to formulation improvements provides, superior knockdown activity at much lower use rates than exhibited in previous generations of this insecticide family.
Pyrethroids are essentially man made versions of a natural insecticide (pyrethrins) derived from chrysanthemum plants that is found in nature. This class of insecticides generally exhibits beneficial characteristics that include high toxicity to insects, low toxicity to humans and fast degradation in the environment.

By low toxicity, we mean that the LD50 of Deltagard is in the range of “greater than 15,000 mg/kg.” This means that in comparison to table salt, deltamethrin (the active ingredient) is 5 times LESS toxic. Sodium chloride or table salt has an LD50 of 3,000 mg/kg. See our library entry Safety Issues- Toxicity & LD50 .

Here at Turf King Hamilton, we will continue to use organic insecticides in our Lawn Care programs where possible. If the situation is such that an particular stubborn infestation needs a pesticide treatment, it is good to know that an insecticide of very low mammalian toxicity such as Deltagard is now available.
