Precision agriculture is highly dependent on the collection of high quality ground truth data to validate algorithms used in prescription maps. However, process collecting labor-intensive and costly. One solution increasing by recruiting citizen scientists through a crowdsourcing platform. In this study, platform application was built using human-centered design process. The primary goals were ...

Alternative strategies to control weeds are required at the field level reduce herbicides and derived pollution. As cover crop, rye (Secale cereale L.) is adopted mainly because of its allelopathic weed control, which takes place through a strong inhibition germination seedling growth in several types grass broad-leaved weeds. The present study consisted of: i) trial, focused on evaluation biom...

Because of the increasing number of glyphosate-resistant weeds, alternate herbicide-resistant crops and herbicides with different modes of action are required to protect crop yield. Glufosinate is a broad-spectrum POST herbicide for weed control in glufosinate-resistant crops, including soybean. The objective of this study was to compare herbicide programs with glufosinate applied singly at lat...

A 50-yr study at Fairbanks, AK, was started in 1984 to determine soil seed longevity of 17 weed species. Seeds were buried in mesh bags 2and 15-cm deep and were recovered 0.7, 1.7, 2.7, 3.7, 4.7, 6.7, 9.7, 19.7, and 24.7 yr later. Viability was determined using germination and tetrazolium tests. By 24.7 yr after burial (YAB), no viable seeds were found for common hempnettle, flixweed, foxtail b...

Abstract Tolpyralate is a 4-hydroxyphenylpyruvate dioxygenase–inhibiting herbicide that applied postemergence for control of annual broadleaf and grass weeds in corn. Current Canadian label recommendations tolpyralate specify the addition methylated seed oil (MSO) adjuvant (MSO Concentrate®) improved weed control. The efficacy with other proprietary adjuvants has not been widely reported peer-r...

Abstract Tolpyralate is an herbicide that usually mixed with atrazine for broad-spectrum weed control in corn. Previous research has provided information on the effective dose (ED) of tolpyralate applied alone and a 1:33.3 mixture atrazine; however, commercially at 30 to 40 g ai ha −1 minimum 560 atrazine. Therefore, five field trials were conducted over 3 yr (2019 2021) determine ED complement...

sulfonylurea herbicides mixtures with phenoxy herbicides can lead to effective control of broadleaved weeds. pot experiments were conducted to study the effect of foramsulfuron and nicosulfuron mixtures with 2,4-d plus mcpa on redroot pigweed and common lambsquarters in 2010 at the greenhouse of agricultural faculty of ferdowsi university of mashhad, iran. experiments were performed as a comple...
