[15N2]-Pyrimethanil

[15N2]-Pyrimethanil is a pesticide used to control fungal diseases in crops such as grapes, apples, and pears. This pesticide is effective against a wide range of fungal pathogens, including Botrytis cinerea, which causes gray mold disease in fruits and vegetables. [15N2]-Pyrimethanil works by inhibiting the enzyme responsible for fungal respiration, thereby preventing the growth and spread of fungal colonies. Chemically, [15N2]-Pyrimethanil is a pyrimidine derivative with a molecular formula of C12H13N5O and a molecular weight of 243.27 g/mol. The compound has two nitrogen atoms that are labeled with the stable isotope 15N, which allows for easy detection and quantification of the pesticide in biological and environmental samples using mass spectrometry. The recommended application rate of [15N2]-Pyrimethanil varies depending on the crop and disease being treated, but typically ranges from 100 to 500 grams per hectare. The pesticide is usually applied as a foliar spray or a post-harvest dip, with multiple applications needed throughout the growing season to ensure effective disease control. While [15N2]-Pyrimethanil is considered a relatively safe pesticide with low toxicity to humans and animals, it is important to follow proper handling and application procedures to minimize exposure and environmental contamination. Additionally, the use of [15N2]-Pyrimethanil should be integrated with other disease management practices, such as crop rotation and cultural controls, to reduce the risk of resistance development and promote sustainable agriculture.
