A season-long survey of common weeds was taken near onion and potato fields located within a large vegetable production region in western New York in 2008 and 2009. The objective was to determine the abundance of weed species known as hosts for Iris yellow spot virus (IYSV), a serious pathogen of onion, Potato leafroll virus (PLRV) and Potato virus Y (PVY), which are major pathogens of potato. ...

Chloroplasts were isolated from triazine-sensitive and triazine-resistant biotypes of common groundsel (Senecio vulgaris L.), common lambsquarter (Chenopodium album L.), and redroot pigweed (Amaranthus retroflexus L.). Chloroplast lipids were extracted and analyzed for differences among sensitive and resistant biotypes. The distribution of lipid between major lipid classes differed in chloropla...

Processing tank was carried out phase 2-3 true leaves (t.l) soybeans. biological efficiency mixtures 70-86% exceeded values benchmark (Galaxy Top, 1.5 + Aramo, l/ha, 65-74%). high noted against ...

Nitrate toxicosis associated with consumption of pigweed red-root (Amaranthus retroflexus) wasdiagnosed in a small herd of cattle in the suburb of Mashhad, northeastern Iran. The clinical signs wereruminal tympany, incoordination, tachycardia, dyspnea, head pressing, aggressive movements and jugulardistension. Seven animals including 3 young calves and 4 cows died of intoxication; other affecte...

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...

allelopathic plants, because of reduction in herbicide uses, are important in weed management. the allelopathic effects of sage salvia officinalis and white wormwood artemisia sieberi water extract were evaluated on germination and seedling growth of redroot pigweed amaranthus retroflexus at concentration of 0, 5, 10, 15, and 20% in controlled conditions. anova revealed that the extract concent...
