Once a year product to kill spider mite eggs and larvae
How often is any miticide effective for a quarter century? By carefully demanding that users apply the product only once per growing season, Gower has been able to keep Hexygon effective for more than a quarter century. I do not follow technical reports, but I have been using this product for at least 25 years and hope it remains effective, with a long residual, for another quarter century. Rotate with horticultural oil and a Neem product growth regulator to work with an adult miticide to make any program to fight mites more effective. Seed World is an outstanding supplier -- excellent prices, prompt shipping, and terrific customer service.
