Show COUNTY AGENTS NOTES Controlling cattle grubs pays. Between early October and November 15 Is the most effective time to treat cattle with insecticides to control the grubs, explained Extension Agent Verl Matthews. For each dollar Invested In materials, labor and other costs associated with cattle grub control treatment, cattle owners can receive returns as high as 10 to 20 dollars. The systemic insecticides are not to be used for treating cattle In Utah from November 15 through 1. There is danger of bad reactions during that period. In spite of the ease of treating cattle with effective organic phosphate insecticides and the great value to be received from such control, many Utah cattle owners are not participating in any cattle grub control program. Consequently the heel flies which lay the eggs on the animals, the larvae that migrate through the tissues of animals and the grubs that eventually emerge through the skin in the animal's backs do damage causing losses that total an estimated $?00 million per year In the U.S. Cattlemen who are. serious about control of grubs in cattle should seek cooperative community effort. Organic phosphates such as Ruelene, Coital, Korlan. Neguvon and Trolene have given satisfactory control of the two types of heel flies and cattle grubs affecting cattle in Utah. |
