Fentin hydroxide is an organotin fungicide, which had been used as a magic bullet for Cercospora leaf spot of beet, because it had been regarded as being not so harmful due to its low vapor pressure and stabile against ultraviolet irradiation. Fentin hydroxide registration as an agricultural chemical was expired in 1990. Fentin hydroxide is now regulated as a class II specified chemical substance under the Act on the Evaluation of Chemical Substances and Regulation of Their Manufacture etc. However, it has been widely used as a insecticide and an antifungal ship bottom paint for a long time, marine pollution and contamination of fish and shellfish have now become a serious problem.
Fentin hydroxide, also known as triphenyltin hydroxide, is actually not a medical substance. It is an organotin compound used as a fungicide for crops like potatoes, sugar beets, and pecans [1]. It works by disrupting the cell membranes of fungi, which prevents them from growing and spreading disease [3].
Fentin hydroxide is a restricted use pesticide (RUP), meaning it can only be applied by certified applicators who have been trained in its safe handling and use. This is because fentin hydroxide can be toxic to humans and animals if not handled properly.
Here are some of the dangers of fentin hydroxide:
- Skin and eye irritation: Contact with fentin hydroxide can irritate the skin and eyes, causing redness, burning, and itching.
- Respiratory problems: Inhaling fentin hydroxide can irritate the nose and throat, and in high doses, it can cause more serious problems like coughing, wheezing, and difficulty breathing.
- Nervous system effects: High exposure to fentin hydroxide can cause headache, nausea, vomiting, dizziness, and convulsions.
Fentin hydroxide is also toxic to aquatic life, so it is important to be careful not to contaminate waterways when using it.
Due to its environmental and health hazards, the use of fentin hydroxide is being phased out in many countries. There are safer and more effective fungicides available.
