The latest session of the "Strategic Farming: Let's Talk Crops!" program, hosted by the University of Minnesota, focused on the emerging field of targeted spray technology.
Dr. Rodrigo Werle, a Weed Scientist from the University of Wisconsin-Madison, shared insights from his research, particularly on how this technology could revolutionize crop management by reducing costs and increasing efficiency.
Targeted spray technology, which includes systems like Bosch and BASF’s One Smart Spray and John Deere’s See & Spray, allows for precise herbicide application by detecting weeds using cameras and AI algorithms.
This technology is especially promising for green-on-brown (weed on fallow land) and green-on-green (weed in crop) applications, making it suitable for diverse farming environments.
During the discussion, Dr. Werle highlighted that these advanced systems are designed to only activate spray nozzles when weeds are detected, which could substantially reduce the amount of herbicide used. This not only leads to cost savings but also lessens the environmental impact of farming.
For instance, initial tests have shown that post-emergence herbicide usage can be reduced by up to 76% in low weed infestation scenarios, although savings drop significantly in high infestation areas.
Moreover, Dr. Werle emphasized the importance of a robust soil residual program as a foundation for effective weed management. He argued that while targeted spraying is beneficial, it should be integrated with other management strategies, such as using cover crops and planting in narrow rows to promote quicker canopy closure.
The potential of targeted spray technology extends beyond just herbicide application. These systems can also create detailed maps of weed distribution and treated areas, providing valuable data for further enhancing farming practices.
As this technology continues to develop and become more integrated into modern farming operations, it promises to bring about significant changes in how farmers manage their crops and combat weeds efficiently.
Farmers interested in adopting this technology should consider all aspects, including the initial costs and the specific needs of their farming operations, to fully benefit from this innovative approach to agriculture.
