Magnesium oxide (MgO) can be used as a synergist in fungicides containing isothiazolinones. Isothiazolinones are a class of biocides that are used to control a wide range of fungi, including molds, mildew, and yeasts. However, they can be inactivated by certain metals, such as copper and zinc. Magnesium oxide can help to prevent this inactivation by chelating these metals.
In addition, Magnesium oxide can also help to improve the solubility of isothiazolinones in water. This is important because isothiazolinones are more effective when they are in solution.
A study published in the journal “Chlorophenols—Advances in Research and Application” found that the addition of Magnesium oxide to a fungicide containing isothiazolinone significantly improved its bioefficacy against a variety of fungi. The study also found that Magnesium oxide was safe to use and did not have any negative effects on the environment.
Overall, Magnesium oxide is a promising synergist for fungicides containing isothiazolinones. It can help to improve the solubility, bioefficacy, and safety of these fungicides.
Here are some specific examples of how Magnesium oxide is used in fungicides:
- In the wood treatment industry, Magnesium oxide is used in combination with isothiazolinones to protect wood from mold and mildew.
- In the agricultural industry, Magnesium oxide is used in combination with isothiazolinones to protect crops from fungal diseases.
- In the food and beverage industry, Magnesium oxide is used in combination with isothiazolinones to prevent the growth of mold and bacteria in food and beverages.
Magnesium oxide is a safe and effective synergist for fungicides containing isothiazolinones. It can help to improve the solubility, bioefficacy, and safety of these fungicides, making them more effective at controlling fungal diseases.
