Description

Fenazaquin is a highly effective acaricide belonging to the quinazoline chemical class, specifically designed for the control of phytophagous mites. Its primary value lies in its potent ovicidal and adulticidal activity, offering long-lasting residual protection for a wide range of crops. This product is essential for agricultural professionals and formulators seeking reliable mite management solutions to protect high-value fruits, vegetables, and ornamental plants from significant yield and quality losses.

Application

Fenazaquin CAS NO 120928-09-8 is a key active ingredient in agricultural miticides, primarily used in the following scenarios:

• Control of spider mites (Tetranychus spp.) and other phytophagous mites on pome fruits like apples and pears.
• Protection of citrus crops from rust mites and spider mites, safeguarding fruit quality and marketability.
• Integrated Pest Management (IPM) programs in vineyards to manage mite populations on grapes.
• Use on nut crops such as almonds, where mite control is critical for tree health and nut yield.
• Application on high-value vegetables including tomatoes, peppers, and cucurbits in both field and protected cultivation systems.
• Ornamental plant production in nurseries and greenhouses to maintain plant aesthetics and health.
• Formulation into various end-use products such as emulsifiable concentrates (EC) and wettable powders (WP) for commercial agricultural use.
