Eriophyid mites damage leaf buds. The new leaves and flowers will be discolored and misshapen. Small brown specks on new leaves are the first indication of an Eriophyid mite infestation. Plants become stunted and misshapen, but usually do not die from this type of mite. Since these mites are extremely tiny, almost transparent in color, and hide in buds, they are very difficult to find even with a magnifying glass.
Mites are very difficult to control.
Destroy heavily infected plants. Increase humidity of the remaining plants' environment, keep infested plants moderately moist at all times, and filter the sunlight falling on infested plants with filmy curtains. Apply less fertilizer. Spray plants weekly with a weak soapy water solution to prevent reinfestation. Foliar miticides should be applied at 7 to 10 day intervals.
