“…Further, it should be noted that the potentially reduced exposure from PF techniques does not necessarily translate into environmental benefits. The technology itself appears to have great potential for achieving the political goal of pesticide reduction (Finger et al 2019; Rajmis, et al 2022), but careful consideration needs to be given to the prospects and limitations that can be assumed after large‐scale adoption of PF. On the one hand, reductions in pesticide use caused by a significant proportion of untreated area can directly relate to reduced side effects on so‐called nontarget organisms.…”

Precision farming technology allows pesticides to be applied precisely to the target while leaving the rest of the field untreated. In the regulation of pesticides, however, a homogeneously sprayed field is considered as the standard scenario. To this end, the current status of pesticide risk assessment from the perspective of terrestrial vertebrates, terrestrial invertebrates, and plants as well as aquatic organisms was examined with respect to the EU registration of a pesticide to be applied via precision farming techniques. We highlight which and how respective parts of the technical procedures could be adapted to account for this technology. Our results demonstrate that large parts of risk assessment procedures can be modified, reducing pesticide application and the exposure to the environment. However, further studies and definite procedures are essential to realistically apply, for example, area restriction in the currently required environmental risk assessment schemes. Precision farming has then great potential to achieve the political and public goal of reducing pesticide use, increasing environmental safety, and enhancing the needs of a sustainable agricultural practice.

“…Another increasingly used method for field spray is the use of drone (unmanned aerial vehicle (UAV)) systems, which take advantage of the airflows to deliver a large amount of the treatment agent on the abaxial surface of the leaves [ 66 ]. The implementation of UAVs has gained popularity in smart crop monitoring and pesticides management as it can provide precise monitoring, large area coverage, timely operation, and optimized operation parameters, which in turn can further improve the effectiveness of pesticide application [ 67 , 68 ]. However, this has not yet been tested for foliar spray of RNAi under field conditions.…”

RNA interference (RNAi) is a powerful tool that is being increasingly utilized for crop protection against viruses, fungal pathogens, and insect pests. The non-transgenic approach of spray-induced gene silencing (SIGS), which relies on spray application of double-stranded RNA (dsRNA) to induce RNAi, has come to prominence due to its safety and environmental benefits in addition to its wide host range and high target specificity. However, along with promising results in recent studies, several factors limiting SIGS RNAi efficiency have been recognized in insects and plants. While sprayed dsRNA on the plant surface can produce a robust RNAi response in some chewing insects, plant uptake and systemic movement of dsRNA is required for delivery to many other target organisms. For example, pests such as sucking insects require the presence of dsRNA in vascular tissues, while many fungal pathogens are predominately located in internal plant tissues. Investigating the mechanisms by which sprayed dsRNA enters and moves through plant tissues and understanding the barriers that may hinder this process are essential for developing efficient ways to deliver dsRNA into plant systems. In this review, we assess current knowledge of the plant foliar and cellular uptake of dsRNA molecules. We will also identify major barriers to uptake, including leaf morphological features as well as environmental factors, and address methods to overcome these barriers.

Three-Dimensional Structure Measurement for Potted Plant Based on Millimeter-Wave Radar

Potted plant canopy extraction requires a fast, accurate, stable, and affordable detection system for precise pesticide application. In this study, we propose a new method for extracting three-dimensional canopy information of potted plants using millimeter-wave radar and evaluate the system on plants in static, rotating, and rotating-while-spraying states. The position and rotation speed of the rotating platform are used to compute the rotation–translation matrix between point clouds, enabling the multi-view point clouds to be overlaid on the world coordinate system. Point cloud extraction is performed by applying the Density-Based Spatial Clustering of Applications with Noise algorithm (DBSCAN), while an Alpha-shape algorithm is used for three-dimensional reconstruction of the canopy. Our measurement results for the 3D reconstruction of plants at different growth stages showed that the reconstruction model has higher accuracy under the rotation condition than that under the static condition, with average relative errors of 41.61% and 10.21%, respectively. The significant correlation between the sampling data with and without spray reached 0.03, indicating that the effect of the droplets on radar detection during the spray process can be neglected. This study provides guidance for plant canopy detection using millimeter-wave radar for advanced agricultural informatization and automation.
