Precision application of specific herbicides to susceptible weeds can significantly save herbicide. This is the first study evaluating the performances of precision sprayer for weed control in turf based on the herbicide weed control spectrum in field conditions. The results showed that EfficientNet-v2 and ResNet never fall below 0.992 for discriminating and detecting the grid cells encompassing weeds susceptible to ACCase-inhibiting and synthetic auxin herbicides. MCPA, a synthetic auxin herbicide, is used to evaluate the performance of the developed smart sprayer for precision control of broadleaf weeds in dormant bermudagrass turf. The developed smart sprayer prototype detected and sprayed every grid cell containing broadleaf weeds in field experiments. Compared to the broadcast application, precision spraying of MCPA provided the same level of control of broadleaf weeds. By 18 days after treatment (DAT), the nontreated control had 13 weeds no. m⁻², while the plots that received broadcast and precision spraying had 0 and 1 broadleaf weed plant no. m⁻², respectively. Precision herbicide application according to the herbicide weed control spectrum (HWCS) with the developed smart sprayer provided the same level of broadleaf weed control and could save more herbicides compared to an approach without discriminating weed species. Overall, these findings clearly indicated that the developed smart sprayer prototype could effectively detect, discriminate, and spray herbicides onto the grid cells containing target weeds based on the HWCS.

对易感杂草精准施药，可显着节省除草剂。这是第一项基于田间条件下除草剂杂草控制谱评估精密喷雾器在草坪上控制杂草性能的研究。结果表明，EfficientNet-v2 和 ResNet 从未低于 0.992，用于区分和检测包含对 ACCase 抑制和合成生长素除草剂敏感的杂草的网格单元。MCPA 是一种合成生长素除草剂，用于评估开发的智能喷雾器对阔叶杂草精准控制的性能在休眠的百慕大草皮中。开发的智能喷雾器原型在田间试验中检测并喷洒了每个含有阔叶杂草的网格单元。与撒施相比，精准喷施 MCPA 对阔叶杂草的控制水平相同。到处理后 18 天 (DAT)，未处理的对照有 13 株杂草。m ⁻²，而在接受撒播和精准喷洒的地块上有 0 株和 1 株阔叶杂草。米^-2， 分别。与不区分杂草种类的方法相比，根据除草剂杂草控制谱 (HWCS) 使用开发的智能喷雾器精准施用除草剂提供了相同水平的阔叶杂草控制，并且可以节省更多的除草剂。总的来说，这些发现清楚地表明，所开发的智能喷雾器原型可以基于 HWCS 有效地检测、区分并将除草剂喷洒到含有目标杂草的网格单元上。
