Description

Norflurazon is a selective pre-emergence herbicide belonging to the pyridazinone chemical class. It is valued for its effective control of a broad spectrum of annual grasses and broadleaf weeds in key agricultural and non-crop settings. This product is essential for professional growers and land managers seeking reliable, long-lasting residual weed control. Its primary applications include use in tree fruits, nuts, vines, and industrial vegetation management.

Application

• Tree Fruit & Nut Orchards: Pre-emergence control of weeds in established almonds, pistachios, citrus, peaches, and pears.
• Vineyards: Management of weed competition in grapevines to optimize water and nutrient uptake.
• Industrial Vegetation Management (IVM): Long-term control of vegetation on non-crop areas such as railways, utilities rights-of-way, and fence lines.
• Forestry: Site preparation and herbaceous weed control in conifer plantations and forest regeneration areas.
• Turfgrass: Selective weed control in certain warm-season turfgrass species like bermudagrass (subject to local label approvals).
• Research & Development: Used as a reference standard and active ingredient in agrochemical formulation studies.
