Description

Asulam is a selective systemic herbicide belonging to the carbamate chemical class. It is valued for its effective control of a broad spectrum of grasses and weeds, particularly in non-crop areas and specific agricultural settings. This product is essential for professionals in the agrochemical industry, forestry management, and turf care seeking reliable, post-emergence vegetation control solutions.

Application

• Selective Weed Control in Sugarcane: Primarily used for post-emergence control of annual and perennial grasses in sugarcane plantations.
• Forestry Management: Applied for vegetation management in forestry, controlling competing weeds and brush to promote tree growth.
• Industrial Vegetation Management (IVM): Effective for managing unwanted vegetation along railways, roadways, pipelines, and utility rights-of-way.
• Turf Management: Used in certain turfgrass settings for selective control of invasive grassy weeds.
• Non-Crop Area Maintenance: Ideal for maintaining clear grounds in airports, storage yards, and similar industrial perimeters.
• Formulation Intermediate: Serves as a key technical-grade active ingredient (TGAI) in the manufacturing of various herbicide formulations.
