TRADE OR OTHER NAMES: The active ingredient triforine is found in a variety of commercial fungicides. Some trade names for products containing triforine include Brolly, Denarin, Funginex, Nimrod T, Saprol, and Triforine DC (1, 242, 207, 363). Triforine is in mixed formulations with carbendazim, permethrin, mancozeb, and bupirimate (1).

REGULATORY STATUS: In the United States, triforine is marketed for use on almonds, apples, asparagus, blueberries, cherries, hops, ornamentals, peaches and roses. Triforine is a "restricted use" pesticide (RUP) with an EPA toxicity classification of I (highly toxic). Check with specific state regulations for local restrictions which may apply. Products containing triforine must bear the Signal Word "Danger" on their label (207, 243).

Outside the U. S. triforine is used on the previously mentioned commodities plus beans, cereals, cotton, cucurbits, grapes, hops, mangoes, mushrooms, sugar beets, tobacco and vegetables. It is also marketed on ornamentals in the home and garden market (243).

INTRODUCTION: Triforine is a piperazine derivative used as a systemic fungicide with protectant, eradicant and curative characteristics. It is used for control of powdery mildew, rusts, black rot and scab on cereals, fruit, ornamentals, and vegetables (1, 242, 207, 243). Triforine is also active against storage diseases of fruit and suppresses red spider mite activity (242). Because of it's low hazard to beneficial insects, triforine may be used in Integrated Pest Management (IPM) programs.

FORMULATION: Triforine comes in emulsifiable concentrates, liquid seed treatments, and wettable powder formulations (1). Triforine is miscible with common insecticides and herbicides in the recommended manner of use (1).
