Site-Specific Weed Control System

Invention Summary

Effective weed control is essential for successful crop production, and herbicides have long been the primary tool due to their high effectiveness, selectivity, and low cost compared to alternative methods. However, their widespread and repeated use has contributed to a significant drawback—the emergence of herbicide-resistant weed populations. To address this growing challenge, a site-specific, weed-removing tillage system offers a promising alternative. Guided by a pre-loaded weed prescription map, this system precisely actuates individual shanks to engage only with weed-infested soil zones, minimizing soil disturbance and reducing the need for chemical herbicides.

Benefits

  • Save energy required for the draft force by the tillage shanks.
  • Reduces soil disturbance, which minimizes soil moisture and nutrient losses.
  • Reduces the wear rate of tillage mechanisms due to reduced use.
  • It can be mounted in the current equipment for large-scale use. 

Applications

  • Weed control in farming using precision farming.
