Thimet Damage on Peanuts
Early season thrips damage is presented in the first two figures (sorry about the focus.) The remaining figures are examples of peanut injury from in-furrow applications of phorate (Thimet or Phorate) on a relatively sandy soil at Lewiston. This level of phorate injury does not affect yield. However, this level of thrips damage can reduce yield by 200 to 500 pounds/acre. Early planted peanuts are most always at the highest level of risk of thrips damage. Populations and damage tend to decrease as later-planted peanuts emerge and grow rapidly.
