Evaluation of Equisetum arvense (Horsetail Macerate) as a Copper Substitute for Pathogen Management in Field-Grown Organic Tomato and Durum Wheat Cultivations

Agriculture, 2020
Effective pathogen management, as an aspect of agroecological crop protection (ACP) necessitates the replacement of copper (Cu) fungicides, but there is little knowledge relating to the performance of potentially suitable alternatives in large-scale ...

Physiologic Specialization of Puccinia triticina on Wheat in the United States in 2002 [PDF]

Plant Disease, 2004
Collections of Puccinia triticina were obtained from rust-infected wheat leaves by cooperators throughout the United States and from surveys of wheat fields and nurseries in the Great Plains, Ohio Valley, Southeast, California, and the Pacific Northwest, in order to determine the virulence of the wheat leaf rust fungus in 2002.

Genetic analysis of adult-plant resistance to leaf rust in a double haploid wheat (Triticum aestivum L. em Thell) population

Genetics and Molecular Biology, 2004
A genetic analysis of adult plant resistance to leaf rust (Puccinia triticina) was performed in in vitro obtained double haploid progenies from a cross between the Brazilian wheat cultivar Trigo BR 35, which, under the high inoculum pressure of the ...

Resistance of triticale to wheat leaf rust (Puccinia triticina) [PDF]

Czech Journal of Genetics and Plant Breeding, 2011
Reactions of winter triticale cultivars mostly from central Europe to recent and old leaf rust isolates were tested in the greenhouse. In one trial 20 cultivars were tested with 8 leaf rust isolates, collected recently from official wheat and triticale trials in the Czech Republic and Slovakia.

The Automation of Hyperspectral Training Library Construction: A Case Study for Wheat and Potato Crops

Remote Sensing, 2021
The potential of hyperspectral measurements for early disease detection has been investigated by many experts over the last 5 years. One of the difficulties is obtaining enough data for training and building a hyperspectral training library.

Short communication: Emergence of a new race of leaf rust with combined virulence to Lr14a and Lr72 genes on durum wheat

Spanish Journal of Agricultural Research, 2016
Leaf rust is a foliar disease caused by the fungus Puccinia triticina that may severely reduce durum wheat yield. Resistance to this pathogen is common in modern durum germplasm but is frequently based on Lr72 and Lr14a.

Verticillium dahliae CFEM Effector VdCR Stabilises the Susceptibility Factor GhAGP31 to Suppress Host Vascular Immunity and Promote Cotton Verticillium Wilt

Plant, Cell &Environment, EarlyView.
ABSTRACT Plant pathogenic fungi secrete a wide array of effector proteins to manipulate host immunity, including those containing CFEM (Common in Fungal Extracellular Membranes) domains. Here, we identified a CFEM domain‐containing effector VdCR from Verticillium dahliae, the causal agent of cotton Verticillium wilt.

Progress Towards Genetics and Breeding for Minor Genes Based Resistance to Ug99 and Other Rusts in CIMMYT High-Yielding Spring Wheat

Journal of Integrative Agriculture, 2014
Wheat rusts continue to cause significant losses worldwide despite major efforts given to their genetic control. This is due to frequent evolution and selection of virulence in pathogen overcoming the deployed race-specific resistance genes. Although the
