Monitoring of the Pesticide Droplet Deposition with a Novel Capacitance Sensor

Abstract: Rapid detection of spraying deposit can contribute to the precision application of plant protection products. In this study, a novel capacitor sensor system was implemented for measuring the spray deposit immediately after herbicide application. Herbicides with different formulations and nozzles in different mode types were included to test the impact on the capacitance of this system. The results showed that there was a linear relationship between the deposit mass and the digital voltage signals of the capaci… Show more

“…In addition, there are relatively few devices that enable real-time monitoring in conjunction with sensor network technology. Although literature on wind speed measuring equipment, methods, and online rapid detection [23] exists, the detection of the downwash airflow field under UAV has not fully been elucidated.…”

“…Therefore, many strategies, mainly different application techniques, have been developed to improve the amount of pesticide deposited on the target plant . To evaluate spraying efficiency, it is imperative that a facile methodology is developed to assess the performance of different spraying techniques in terms of distribution and the amount of product deposited on target crops …”

“…2,3 To evaluate spraying efficiency, it is imperative that a facile methodology is developed to assess the performance of different spraying techniques in terms of distribution and the amount of product deposited on target crops. [4][5][6] When assessing spray deposition, if pesticides themselves are used in each application scenario, different analytical methods are needed to determine the pesticide deposited on the target crops due to the different physicochemical properties of each pesticide. This is time and cost prohibitive.…”

“…A total of 13 papers were published in this Special Issue entitled: "Emerging Sensor Technology in Agriculture", and the topics addressed include different emerging technologies with applications on ecosystems (grasslands) [1] and several agriculture crops such as peppers [2], apples [2,3], grapevines [2,[4][5][6][7], cocoa trees [6], citrus [8], legumes [9], wheat and rice [10,11]. Two papers were also related to the use of remote sensing to detect forage quality [9], regions of interest of pigs [12], and pesticide droplet deposition [13] using machine learning.…”

“…Other management practices such as pesticide application require accurate monitoring methods to assess efficiency in the distribution of droplets within crop canopies to minimize detrimental effects in the environment and maximize application efficiency. A rapid method to detect spraying deposit was developed based on capacitance sensors [13].…”
