• Abstract: Italian ryegrass is a grass weed commonly found in winter wheat fields that are competitive with winter wheat for moisture and nutrients. Ryegrass can cause substantial reductions in yield and grain quality if not properly controlled with the use of herbicides. To control the cost and environmental impact we detect weeds in drone and satellite imagery. Satellite imagery is too coarse to be used for precision spraying, but can aid in planning drone flights and treatments. Drone images on the other hand have sufficiently good resolution for precision spraying. However, ryegrass is hard to distinguish from the crop and annotation requires expert knowledge. We used the Python segmentation models library to test more than 600 different neural network architectures for weed segmentation in drone images and we map accuracy versus the cost of the model prediction for these. Our best system applies herbicides to over 99% of the weeds while only spraying an area 30% larger than the annotated weed area. These models yield large savings if the weed covers a small part of the field.

  Invasive plant species are detrimental to ecology of both agricultural and wildland areas. Invasive plant species such as Euphorbia esula, or leafy spurge, have spread through much of North America from Eastern Europe. We gathered a dataset of leafy spurge presence and absence in grasslands of western Montana, USA, then surveyed these areas with a commercial drone. We trained image classifiers on these data, and our best performing model, a pre-trained DINOv2 vision transformer, identified leafy spurge with 0.84 accuracy.

  HarvestNet is a dataset for mapping the presence of farms in the Ethiopian regions of Tigray and Amhara during 2020-2023. We introduce a new approach based on the detection of harvest piles characteristic of many smallholder systems. We conclude that remote sensing of harvest piles can contribute to more timely and accurate cropland assessments in food insecure regions.

• Site-specific weed management in corn using UAS imagery analysis and computer vision techniques [0.0]
  Currently, weed control in commercial corn production is performed without considering weed distribution information in the field. The objective of this study was to perform site-specific weed control (SSWC) in a corn field by 1) using an unmanned aerial system (UAS) to map the spatial distribution information of weeds in the field. Using our SSWC approach, we were able to save 26.23% of the land (1.97 acres) from being sprayed with chemical herbicides compared to the existing method.
