Cover crops, tillage, and the suppression of soil borne diseases in soybean
Cover crops have historically been shown to be useful in the management of pathogens of high value crops, such as fruits, vegetables, and nuts. However, the properties of these cover crops and the type of suppressive soil that they induce, can be useful in the production of agronomic crops as well. …

Utilisation of Proximal Sensing Technology to Map Variability in Ontario Vineyards
… used for the optimisation of production in agronomic crops. The overall goal of this study was to determine whether high resolution proximally sensed observations acquired by the GreenSeeker™ technology could be correlated with soil moisture, vine water status, yield components and grape …

Use of Fluridone for Control of Palmer Amaranth (Amaranthus palmeri) in Cotton (Gossypium hirsutum) and on Ditchbanks
… has been considered the most problematic weed in agronomic crops across the Midsouth. As a result of glyphosate resistance, producers began to again utilize a diverse herbicide program for management of this weed, which consists of several soil-residual herbicides most notably diuron, fluometuron, …

The Evaluation of Root System Architecture (RSA) As A New Breeding Target for Climate-Resilient Winter Wheat (Tritium aestivum L.)
… production will depend on genetic capacity of crops to adapt to increased biotic and abiotic barriers induced by climate change. Historically, shoot-based traits were breeding targets for overcoming yield gaps between developed and undeveloped nations. However, the rate of genetic gain has …

A Genomic and Proteomic Investigation of the Plant Pathogen Armillaria mellea: Buried Treasure or Hidden Threat?
… mellea is a major plant pathogen of timber and agronomic crops. Yet, no large-scale “-omics” data are available to enable new studies, and limited experimental models are available to investigate basidiomycete pathogenicity. Herein it is revealed that the A. mellea genome comprises 58.35 Mb, …

Prickly Sida (Sida spinosa L.): Biology and In-Crop and Post-Harvest Management Programs
… southern U.S. and is a troublesome weed in many agronomic crops. In northeastern Louisiana on silty clay loam and clay soils, prickly sida seedling emergence began in early March when soil temperature reached 13.8 C and ceased in mid-October. Seasonal peaks in emergence were associated with …

Preferences of Louisiana agronomic crop producers and crop consultants regarding sources of information related to agricultural production
The dissemination of information related to agronomic crop production is crucial to the success of the agriculture industry in Louisiana. This information is distributed by various sources and through multiple methods. The primary purpose of this study was to determine the preferences of Louisiana …
