Dichlone is a fungicide that belongs to the quinone class. Dichlone alters the permeability of the cell membrane in fibroblastic cells. It rapidly enters the cell and stimulates oxygen uptake.

Dichlone is not approved in the European Union. A default MRL of 0.01 mg/kg has been set according to Art 18(1)(b) Reg 396/2005.
Dichlone is used to control various fungi in fruit, vegetables, ornamentals, and field crops, particularly blossom blights, scab in apples and pears, and brown rot in stone fruit.

Application

It is intended to be used as a certified reference material (CRM) for calibration in chromatography and other analytical techniques. Dichlone CRM may also find its use as mentioned below:

• To evaluate the toxicity of some naturally occurring quinones and easily synthesized quinone derivatives on the two-spotted spider mite and three aphid species in laboratory and greenhouse conditions
• To assess antifeedant and toxic effects of selected quinones against the cabbage looper, Trichoplusia ni larvae
• Evaluation of four 1,4-naphthoquinones and 10 pyrimidinone-fused 1,4-naphthoquinones for antimicrobial activity against drug-resistant oral bacteria
• To determine the effectiveness of the use of Supercritical Fluid Extraction (SFE) and Supercritical Fluid Chromatography (SFC) techniques in the analysis of the levels of pesticide residues in canned foods, vegetables, and fruits
