Summary: This paper provides an overview of research on plant pest control. It reviews the history of the struggle against plant diseases, insects, and weeds and summarizes ancient Chinese agricultural books' thoughts on plant protection. The paper identifies plant pests as a target and presents six types of plant protection methods and 36 subdivision measures. It also reviews the development of pesticide application technology, with a focus on performance measurement and simulation and modeling of pesticide-spraying systems. The paper concludes by proposing three suggestions for further research in plant protection, including considerations for human and environmental health, sustainable and eco-friendly application media, and efficient application equipment systems.

Summary: With increasing pest and pathogen challenges, there is a need for innovative and sustainable solutions for plant protection, such as RNA interference-based pesticides. These products target organisms specifically through the interaction of siRNAs with target RNAs. The regulatory frameworks for pesticide authorization in the US and EU are evolving to address the use of dsRNA-based pesticides.

Summary: Site-specific pesticide applications in precision agriculture have the potential to reduce pesticide use and bring economic benefits. In the 'AssSys' research project, the economic evaluation of site-specific pesticide applications was conducted using a direct injection sprayer system and an automatic application assistant. Field trials and scenario analysis showed cost savings of 26-66% and a clear economic advantage for site-specific applications compared to conventional applications.

Summary: With the changing climate and ecological conditions in farmland, pest outbreaks in agricultural landscapes are becoming more frequent, increasing the need for improved crop production tools and methods. UAV-based agricultural spraying is seen as an important new technology for efficient and effective applications of crop protection products. This paper reviews the current research and progress on UAV application technologies for plant protection, discusses characteristics of atomization by unmanned aircraft application systems, analyzes factors influencing spraying performance, and considers key technologies for reducing drift and enhancing application efficiency.

Summary: The degradation kinetics of pesticides in plants play a crucial role in modeling pesticide residual concentrations. This study proposes a modeling approach using potatoes as a model crop to estimate the degradation rate constants of pesticides in plants. The simulations show that the growth dynamics of potatoes and variations in weather conditions and soil properties can significantly affect the degradation kinetics of pesticides in plants.

Summary: This study evaluated Indian rice farmers' intention to use pesticides and found that most farmers had positive attitudes towards pesticide use but lacked perceived behavioral control and knowledge of safe pesticide use. The study emphasized the crucial role of knowledge, subjective norms, and moral norms in intention to use pesticides.

Summary: This study examines the impact of specialized agricultural services on pesticide application intensity in China and finds that it has dual effects, directly increasing intensity and indirectly reducing intensity. Crop protection services are seen as a core force in reducing pesticide application intensity.

Summary: The study proposed a mechanism-based model to understand the fate of pesticides on plant surfaces. Simulation results showed that pesticide spray solution dissipated rapidly, forming a saturated pesticide solution on plant surfaces, which facilitated the diffusion of pesticide residues into peel tissues.

Summary: This study identified the factors affecting the generation rate of wasted plastic pesticide containers after pesticide application using data from 106 farmers in Greece. Through mathematical modeling and linear regression, significant parameters such as cultivated area, type of crop, and type of pesticide application were found to influence generation rates. The study also estimated the total wasted plastic pesticide containers generation rate in Greece and provided models for predicting regional and national generation rates.

Summary: In order to solve the problem of herbicide residues exceeding the safety standard in open-field cabbage, an intermittent weed spraying control method was proposed by integrating cabbage position, cabbage canopy size, and spraying machine operation speed. Experimental verification showed that the method had high accuracy and significant herbicide-saving effects, which is of great significance for improving the herbicide utilization rate and ensuring the safety of agricultural products.

Summary: Pesticide application techniques are crucial for integrated pest management and environmental safety. A modeling approach based on plant uptake models was proposed to evaluate the efficiency of different pesticide application methods. The results showed that soil-based transpiration route facilitated the accumulation of moderately lipophilic compounds in plant tissues, while plant surface-based exposure route was more favorable for highly lipophilic compounds.

Summary: This study investigated the dermal exposure of plant protection products during spraying, focusing on the impact of nozzle types on spray drift. The use of drift reduction nozzles was found to significantly reduce potential exposure, exceeding the EFSA-recommended drift reduction threshold.

Summary: Plants have evolved adaptive strategies to cope with pathogen infections, including establishing immune memory to enhance their responsiveness to pathogens. Seed priming, as an environmentally-friendly crop protection technique, can effectively induce plant immune memory and enhance disease resistance in crops.
