Basis 75

Technological Precision in Maize Weed Control

«Basis 75» by DuPont is more than just a post-emergence herbicide; it is a sophisticated tool built on the synergy of two sulfonylureas: rimsulfuron and thifensulfuron-methyl. This dual-action composition addresses a vast spectrum of field challenges, from perennial couch grass and thistle to aggressive annuals like common lambsquarters and green foxtail.

The Mechanism of Selectivity

The core objective of this herbicide is to strike the weed without harming the crop. DuPont’s system achieves this through selective action: the components inhibit the acetolactate synthase (ALS) enzyme, which is vital for weed cell division. Within the maize plant, the active ingredients are metabolized rapidly, making this one of the safest systemic options available for corn crops.

Engineering Aspects and Field Application

• Systemic Efficacy: Unlike contact herbicides, Basis 75 is rapidly absorbed by leaves and translocated to growth points. This is critical for controlling rhizomatous perennials like couch grass and thistle.
• Formulation Science: The water-dispersible granule formulation ensures optimal solubility and stability of the tank mix, preventing nozzle clogging and ensuring uniform coverage.
• Dosage and Strategy: Maximum efficiency is achieved at a rate of up to 25 grams per hectare. The selectivity of the formula allows for a single-pass treatment per season, significantly optimizing logistics and input costs.

For the professional agronomist, the short pre-harvest interval is a key indicator of quality. With only a 1-day safety window post-application, the product demonstrates high technological efficiency and rapid environmental biodegradation.
