However, the growing environmental concerns associated with herbicide treatments have motivated the adoption of precise chemical control approaches that detect and treat infested areas exclusively. The main challenge in developing such control practices for O. cumana lies in the fact that most of its life-cycle occurs in the soil sub-surface and by the time shoots emerge and become observable, the damage to the crop is irreversible. This paper approaches early O. cumana detection by hypothesizing that its parasitism already impacts the host plant morphology at the sub-soil surface developmental stage. To validate this hypothesis, O. cumana- infested sunflower and non-infested control plants were grown in pots and imaged weekly over 45-day period. Three-dimensional plant models were reconstructed using image-based multi-view stereo followed by derivation of their morphological parameters, down to the organ-level. Among the parameters estimated, height and first internode length were the earliest definitive indicators of infection. Furthermore, the detection timing of both parameters was early enough for herbicide post-emergence application. Considering the fact that 3-D morphological modeling is nondestructive, is based on commercially available RGB sensors and can be used under natural illumination; this approach holds potential contribution for site specific pre-emergence managements of parasitic weeds and as a phenotyping tool in O. cumana resistant sunflower breeding projects.<\/jats:p>","DOI":"10.3390\/s19071569","type":"journal-article","created":{"date-parts":[[2019,4,2]],"date-time":"2019-04-02T03:21:26Z","timestamp":1554175286000},"page":"1569","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["3-D Image-Driven Morphological Crop Analysis: A Novel Method for Detection of Sunflower Broomrape Initial Subsoil Parasitism"],"prefix":"10.3390","volume":"19","author":[{"given":"Ran Nisim","family":"Lati","sequence":"first","affiliation":[{"name":"Department of Plant Pathology and Weed Research, Newe Ya\u2019ar Research Center, Agricultural Research Organization, Ramat Yishay 30095, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sagi","family":"Filin","sequence":"additional","affiliation":[{"name":"Mapping and Geo-Information Engineering, Technion-Israel Institute of Technology, Haifa 3200003, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3084-4485","authenticated-orcid":false,"given":"Bashar","family":"Elnashef","sequence":"additional","affiliation":[{"name":"Mapping and Geo-Information Engineering, Technion-Israel Institute of Technology, Haifa 3200003, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hanan","family":"Eizenberg","sequence":"additional","affiliation":[{"name":"Department of Plant Pathology and Weed Research, Newe Ya\u2019ar Research Center, Agricultural Research Organization, Ramat Yishay 30095, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,4,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"586","DOI":"10.1007\/s11119-013-9317-6","article-title":"Plant growth parameter estimation from sparse 3D reconstruction based on highly-textured feature points","volume":"14","author":"Lati","year":"2013","journal-title":"Precis.
