Description

Isopropalin is a selective pre-emergence herbicide belonging to the dinitroaniline chemical class. This compound is valued for its effectiveness in controlling a broad spectrum of annual grasses and certain broadleaf weeds in key agricultural systems. It is primarily utilized by the agricultural industry for crop protection in fields such as tobacco, vegetables, and certain fruits. Isopropalin CAS NO 33820-53-0 offers reliable residual soil activity, providing extended weed control to support healthy crop establishment and yield.

Application

• Pre-emergence Herbicide for Tobacco: Provides critical early-season control of grasses and weeds in tobacco fields, reducing competition for nutrients and water.
• Vegetable Crop Protection: Used in the cultivation of tomatoes, peppers, and other vegetable crops to ensure clean fields and minimize manual weeding costs.
• Orchard and Vineyard Management: Applied in non-bearing or established tree fruit and grape vineyards to manage weed populations in the row middles.
• Nursery and Ornamental Production: Supports weed-free growth in container and field nursery stock, maintaining plant quality and market value.
• Industrial Vegetation Control: Employed in non-crop areas, such as around farm buildings or storage yards, for total vegetation management.
• Research and Development: Serves as a reference standard or active ingredient sample for agrochemical formulation development and efficacy studies.
