Within the Veneto Carbon Living Lab, early in-field diagnosis of herbicide resistance is integrated with the planning of targeted management strategies. These strategies aim both to control emerged weeds and to reduce the seed dispersal of those not managed by the adopted techniques, in order to ensure optimal crop yield and long-term seed bank management.

The technology used for diagnosing resistance to ALS (acetolactate synthase) inhibitors in the field is called LAMP (Loop-Mediated Isothermal Amplification). This method was developed to provide rapid results on the resistance status of four different Amaranthus species—a genus that is widespread and particularly problematic in soybean cultivation.

Following diagnosis, various control strategies (both chemical and non-chemical) are implemented to manage the severe infestations reported by farmers participating in the Living Lab. If necessary, an intervention is carried out just before soybean harvest using a wick applicator and a systemic, non-selective herbicide (glyphosate). This tool allows for the targeted treatment of plants that grow above the crop canopy, thereby preventing further seed dispersal.

Objectives 

The specific objective of this activity is to test various sustainable weed management strategies on pilot farms, and to implement innovations in weed control aimed at reducing the environmental impact of herbicides and the selection pressure on resistant weed populations. The goal is also to preserve soil carbon content and to reduce both water use and contamination.
