Smart spray technology developed at the University of Florida was designed to reduce off-target applications when applying postemergence (POST) herbicides for weed control in plasticulture systems. A trial was conducted in the fall of 2021 and spring of 2022 to evaluate smart spray technology in row middles in a banana pepper field at the Gulf Coast Research and Education Center in Balm, FL. The objective of this study was to evaluate the efficacy of targeted POST-herbicide applications in plasticulture pepper row middles in the presence or absence of a pre-emergent (PRE) herbicide. Flumioxazin reduced broadleaf and overall weed densities in both seasons and lowered grass density in the spring. Two targeted applications reduced the nutsedge density in spring compared to the two banded applications. No significant pepper damage was observed in any treatments. Applied POST herbicide volume following PRE-herbicide was reduced by 84% and 54% for fall and spring respectively. In the absence of a PRE herbicide, targeted applications reduced POST-herbicide volumes by 30% and 45% for fall and spring respectively. No reduction in weed control or pepper yield was observed when comparing targeted with banded applications. Overall, the use of smart spray technology for POST herbicides in row middles reduced applied spray volume with no reduction in weed control, significant injuries on pepper, or negative effects on yield.

佛罗里达大学开发的智能喷雾技术旨在减少在塑料栽培系统中使用芽后（POST）除草剂控制杂草时的脱靶现象。佛罗里达州巴尔姆市墨西哥湾沿岸研究和教育中心于 2021 年秋季和 2022 年春季进行了一项试验，以评估香蕉胡椒田行中的智能喷雾技术。本研究的目的是评估在存在或不存在芽前 (PRE) 除草剂的情况下，在塑料栽培辣椒行中部施用靶向后除草剂的效果。氟菌嗪降低了两个季节的阔叶杂草和整体杂草密度，并降低了春季的草密度。与两个带状应用相比，两个目标应用降低了弹簧中的坚果密度。在任何处理中均未观察到明显的辣椒损害。秋季和春季，事前除草剂后的事后除草剂施用量分别减少了 84% 和 54%。在没有使用前除草剂的情况下，有针对性的施用使秋季和春季的后除草剂用量分别减少了 30% 和 45%。与定向施用和条带施用相比，没有观察到杂草控制或辣椒产量下降。总体而言，在行中使用智能喷雾技术进行后除草剂减少了喷雾量，但杂草控制没有减少，辣椒受到重大伤害或对产量产生负面影响。
