Dicofol

Dicofol is a highly effective active ingredient belonging to the organochlorine chemical class, specifically within the diphenyl-ethanol derivative group. Its primary function is that of a contact acaricide, utilized extensively to control populations of spider mites and other phytophagous mites across a wide range of agricultural and horticultural crops.

The mechanism of action of dicofol involves the disruption of oxidative phosphorylation processes within the pest's organism. This interference leads to paralysis and the eventual death of the mites. The substance is highly toxic to various life stages, including larvae, nymphs, and adults, though it exhibits limited ovicidal activity against mite eggs.

The compound is widely applied in the protection of fruit trees, vegetable crops, vineyards, and ornamental plants. It demonstrates significant efficacy against spider mites (Tetranychidae family) and gall mites. Due to its excellent adherence to leaf surfaces, it provides long-lasting residual protection following application, safeguarding crops from re-infestation.

Application procedures require thorough coverage of the leaf surface with the working solution, as dicofol lacks systemic properties and does not translocate within plant tissues. The optimal time for application is immediately upon the detection of the first signs of mite infestation, taking into account ambient temperatures and plant health to minimize potential phytotoxicity.

Safety precautions are of paramount importance when handling this substance due to its potential toxicity to humans and the environment. Operators must use full personal protective equipment, including respirators and chemical-resistant gloves. The use of dicofol is prohibited in water protection zones due to its extreme toxicity to aquatic organisms, and strict pre-harvest intervals must be adhered to in all cases.
