Rotation of abamectin (Zephyr), hexythiazox (Onager), or other recently registered miticides with the older miticides may help to reduce resistance to any one of them and slow the development of resistance in areas where it is not yet a problem.
Abamectin (Zephyr) is effective against mites anytime during the season but works best early to mid-season before the leaf ages and "hardens off".
At this point it is important to determine their level of resistance to dicofol, propargite, and abamectin when determining the best miticide to use.
