Accurate information on the spatial distribution of weeds is key to effective site-specific weed management and efficient sustainable use control measures. This work focuses early detection johnsongrass, common cocklebur velvetleaf present in a corn field using high resolution airborne hyperspectral imagery acquired when plants were four six leaf growth stage. Following appropriate radiometric ...

The mediation of herbicide effects on weed-crop combinations by vesicular-arbuscular mycorrhizal (VAM) fungi is essentially unknown. We conducted a greenhouse study to determine if VAM fungi, whose hyphae interconnect the roots of adjacent plants, modify herbicide effects by enhancing nutrient fluxes between associated plants. Soybean (Glyc ine max (L.) Merr.) and common cocklebur ( X a n t h i...

Knowing precise location and having accurate information about weed species is a prerequisite for developing an effective site-specific management (SSWM) system. Due to the effectiveness of deep learning techniques vision-based tasks such as image classification object detection, its use discriminating between weeds crops gaining acceptance among agricultural research community. However, limite...

Iron administration to iron-starved cocklebur (Xanthium pensylvanicum) plants causes an increase in the iron content of ferritin fractions extracted from mature leaves. Xanthium plants grown under long days (vegetative stage) have more iron and ferritin than similarly iron-treated plants induced to flower under short day regimes. This first demonstration of ferritin in cocklebur (Compositae) le...

We present the case of a 7-year-old male patient with bilateral bronchial cocklebur fruit aspiration, which he sustained while playing. The patient presented with a triad of cough, wheezing, and decreased breath sounds (decreased in the right lung and absent in the left). These symptoms led to a diagnosis of bilateral bronchial foreign body, which was confirmed by computed tomography three-dime...
