It is difficult to treat this pest as there is fruit on the tree. Normally we would say to treat the white scale and mites with PestOil or Yates White Oil. These products will coat and suffocate these pests. There is only a one day withholding period when using these products. The problem arises as you wouldn't really want any of the oil to coat the skin of the fig as it is such a delicate fruit. The oil may have the effect of burning the soft, tender skin on the fig. Perhaps you could pick the fruit (hopefully they will be ready to be harvested) and then spray the branches and leaves that have scale on them. When you do spray, make sure that the temperature is mild and does not exceed 30 degrees C. Ensure that the soil is moist at the time of spraying and the tree is not under any stress. Also, try Yates Nature's Way Citrus & Ornamental Spray. How wonderful to have a 50 year old tree. You must have well and truly looked after it. Happy fig eating.
