The Control of Stem Blight and the Spread of Potato Late Blight by Copper Seed Treatment [PDF]

, 2008
Late blight still is an unsolved problem in organic potato farming. Up to now the most effective way to control this disease is the use of copper fungicides. Transferring results from regular farming, seed treatments with copper fungicides shall postpone

Control of Potato Late Blight by Cyazofamid

Journal of Pesticide Science, 2005
To evaluate the efficacy of the novel fungicide cyazofamid against potato late blight, 5 field tests were carried out in 1998-2000. Cyazofamid provided excellent control of late blight in the field. In preventative scheduled application tests, the efficacy of cyazofamid at dose rates of 67 and 100 μg active ingredient (a.i.)/ml with 10-day and 14-day ...

Using herbarium collections to study genetic responses to global change

New Phytologist, EarlyView.
Summary Earth's c. 406 million herbarium specimens represent a largely untapped resource of genetic data that could transform our understanding of global plant populations. Advances in DNA sequencing have made the extraction of genetic data from these preserved specimens increasingly feasible, enabling new insights into plant biodiversity and ...

The anti-Phytophthora effect of selected potato-associated Pseudomonas strains: from the laboratory to the field

Frontiers in Microbiology, 2015
Late blight, caused by the oomycete Phytophthora infestans, is the most devastating disease of potato. In organic farming, late Late blight, caused by the oomycete Phytophthora infestans, is the most devastating disease of potato.

Host‐Induced Silencing of Rhizoctonia Solani 5‐Enolpyruvylshikimate‐3‐Phosphate Synthase Impairs Its Virulence in Rice

Plant Biotechnology Journal, EarlyView.
ABSTRACT Sheath blight disease of rice caused by the fungal pathogen R. solani AG1‐IA remains a big threat to rice production worldwide. A limited genetic variation in rice for tolerance to this pathogen and little success in understanding how it defeats host defence are major reasons behind it.

A Mobile App for Detecting Potato Crop Diseases

Journal of Imaging
Artificial intelligence techniques are now widely used in various agricultural applications, including the detection of devastating diseases such as late blight (Phytophthora infestans) and early blight (Alternaria solani) affecting potato (Solanum ...

Yield losses caused by late blight (Phytophthora infestans (Mont.) de Bary) in potato crops in Ireland [PDF]

, 2008
peer-reviewedField experiments, using foliage blight susceptible cultivars, were conducted at Oak Park, Carlow from 1983 to 2007 to determine the loss in potato production caused by crop infection with Phytophthora infestans.

OsRALF26 Serves as an Endogenous Signal Recognised by XA21 to Promote Robust and Distal Resistance in Rice

Plant Biotechnology Journal, EarlyView.
ABSTRACT Plant immune receptors detect both microbe‐derived and endogenous signals to activate defences. XA21, a rice immune receptor, confers strong race‐specific resistance to a subset of Xanthomonas oryzae pv. oryzae (Xoo) strains by recognising the microbial sulphated peptide RaxX.

Hypersensitive response to Potato virus Y in potato cultivar Sárpo Mira is conferred by the Ny-Smira gene located on the long arm of chromosome IX [PDF]

, 2014
Potato virus Y (PVY, Potyvirus) is the fifth most important plant virus worldwide in terms of economic and scientific impact. It infects members of the family Solanaceae and causes losses in potato, tomato, tobacco, pepper and petunia production.

Sweet Potato Gene Clusters Control Anthocyanin Biosynthesis and Leaf Morphology

Plant Biotechnology Journal, EarlyView.
ABSTRACT Sweet potato (Ipomoea batatas) exhibits diversity in pigmentation and leaf morphology, yet the genetic architecture and regulatory organisation underlying these traits remain poorly resolved, particularly with respect to organ‐specific control.
