Kelthane (dicofol)
Kelthane is an nonsystemic organochlorine miticide with contact activity. It is registered for use on apples, pears, and quince and can be used at any time during the season. Widespread resistance of European red mite to Kelthane has reduced its efficacy. In areas where resistance has not developed, limiting use to only once per year may delay resistance. Kelthane is compatible in tank mixes with other chemicals except those that cause high alkalinity (pH > 8).
Stethorus and predatory mites tolerate Kelthane applications.
