Discrimination of Morningglory Species (Ipomoea spp.) Using Near-Infrared Spectroscopy and Multivariate Analysis

Weed science, 2023
The occurrence of weeds is one of the main factors limiting agricultural productivity. Studies on new techniques for the identification of these species can contribute to the development of proximal sensors, which in the future might be coupled to ...

Measuring Interference from Midseason Tall Morningglory (Ipomoea purpurea) to Develop a Model for Teaching Weed Seedbank Effects on Chile Pepper

Weed technology, 2017
Tactics that target seedbanks are important components of weed management systems; however, such tactics can be difficult to adopt because consequences of seedbank reduction are often unclear. This study developed model-based software to provide insights

Seed Dormancy and Germination Ecology of Three Morningglory Species: Ipomoea lacunosa, I. hederacea, and I. purpurea

Seeds
Morningglories (Ipomoea lacunosa, I. hederacea, and I. purpurea) are persistent, problematic weeds in summer row crops throughout warm-temperate regions.

Diminishing weed control exacerbates maize yield loss to adverse weather. [PDF]

Glob Chang Biol, 2021
Individually, adverse weather and weed interference cause significant maize yield losses; however, the combined effects of the two on maize is poorly understood. Using machine learning techniques on a database of herbicide trials spanning 27 years, we identified poor late‐season weed control, high temperatures, and low water availability during silking

Sugarcane Crop Residue and Bagasse Allelopathic Impact on Oat (Avena sative L.), Tall Morningglory (Ipomoea purpurea L. Roth), and Redroot Pigweed (Amaranthus retroflexus L.) Germination

, 2018
Allelopathy, the chemical interaction between plants, may result in the inhibition of plant growth and development, and includes compounds released from a primary crop that adversely impact crop or weed species.

Impact of volatility reduction agents on dicamba and glyphosate spray solution pH, droplet dynamics, and weed control. [PDF]

Pest Manag Sci, 2023
Dicamba and glyphosate spray solution pH, droplet dynamics (size and velocity), and weed control as impacted by recent federally mandated volatility reduction agents (VRAs) were evaluated across a broad geography. Abstract BACKGROUND Regulations in 2021 required the addition of a volatility reduction agent (VRA) to dicamba spray mixtures for ...

Pest categorisation of <i>Pantoea ananatis</i>. [PDF]

EFSA J, 2023
Abstract The EFSA Plant Health Panel performed a pest categorisation of Pantoea ananatis, a Gram‐negative bacterium belonging to the Erwiniaceae family. P. ananatis is a well‐defined taxonomic unit; nonetheless, its pathogenic nature is not well defined and non‐pathogenic populations are known to occupy several, very different environmental niches as ...

Deep learning-based laser weed control compared to conventional herbicide application across three vegetable production systems. [PDF]

Pest Manag Sci
In 2024, trials in New Jersey and New York evaluated the effectiveness of laser weeding with a Carbon Robotics unit compared with herbicides on beets, spinach, and peas. Results demonstrated that laser weeding was as effective or superior to herbicides in controlling weeds, reducing biomass by ≥97% and boosting crop growth by ≥30%.

FMC 57020 Effects on Chloroplast Development in Pitted Morningglory (Ipomoea lacunosa) Cotyledons

Weed science, 1985
The effect of FMC 57020 [2-(2-chlorophenyl) methyl-4,4-dimethyl-3-isoxalidinone] on chloroplast development was examined in the cotyledons of 5-day-old, etiolated pitted morningglory (Ipomoea lacunosaL.

Interspecific variation in persistence of buried weed seeds follows trade-offs among physiological, chemical, and physical seed defenses. [PDF]

Ecol Evol, 2016
Improved understanding of factors driving variation in persistence of weed seeds in soil seedbanks is needed to support more effective management approaches. We quantified interspecific trade‐offs among physiological, chemical, and physical traits of weed seeds and their persistence in the soil seedbank in a common garden study.
