Vultur

Mechanism of Action and Selectivity of "Vultur"

"Vultur" by Rangoli is a highly specialized contact herbicide utilizing bentazone as its core active ingredient. Belonging to the benzothiadiazinone chemical group, it serves as a potent inhibitor of photosynthesis (the Hill reaction) in broad-leaved weeds. Its primary strength lies in its selectivity: while it effectively disrupts metabolic pathways in weeds, the soybean crop remains unharmed due to its internal ability to metabolize the compound.

Technical Dynamics of Foliar Application

As a contact herbicide, Vultur does not translocate through the plant's vascular system. It acts locally upon contact with the leaf tissue. This technical nuance dictates the application strategy: the success of the treatment depends heavily on the coverage quality of the sprayer nozzles. The water-soluble concentrate formula is designed to penetrate the weed cuticle rapidly, ensuring that troublesome species like ragweed, mustard, and lamb's quarters are neutralized shortly after application.

Operational Guidelines

• Optimal Growth Stage: Since Vultur acts as a post-emergence herbicide, application is most effective when target weeds are in the 2- to 4-leaf stage. At this developmental phase, the metabolic rate of the weeds is highly sensitive to benzothiadiazinone interference.
• Application Rates: The dosage range of 1.0–2.0 L/ha provides agronomists with the flexibility to adjust the treatment intensity based on the specific weed pressure in the field.
• Strategic Use: As a selective herbicide, it is an essential "insurance" tool when early-season soil-applied herbicides fail to provide complete control.

Vultur is classified under Hazard Class 3, necessitating proper protective equipment during handling. With a limit of one application per season, timing is crucial for maximizing the yield potential of the soybean crop.
