Sustaining the Future of Plant Breeding: The Critical Role of the USDA‐ARS National Plant Germplasm System

Crop Science, Volume 58, Issue 2, Page 451-468, March–April 2018., 2018
Plant breeders require genetic diversity to develop cultivars that are productive, nutritious, tolerant of biotic and abiotic stresses, and make efficient use of water and fertilizer. The USDA‐ARS National Plant Germplasm System (NPGS) is a major source for global plant genetic resources (PGR), with accessions representing improved cultivars, breeding ...

Phosphite: a novel P fertilizer for weed management and pathogen control

Plant Biotechnology Journal, Volume 15, Issue 12, Page 1493-1508, December 2017., 2017
Summary The availability of orthophosphate (Pi) is a key determinant of crop productivity because its accessibility to plants is poor due to its conversion to unavailable forms. Weed's competition for this essential macronutrient further reduces its bio‐availability.

Pest categorisation of Elsinoë fawcettii and E. australis

EFSA Journal, Volume 15, Issue 12, December 2017., 2017
Abstract The Panel on Plant Health performed a pest categorisation of Elsinoë fawcettii and E. australis, the causal agents of citrus scab diseases, for the EU. The identities of the pests are well‐established and reliable methods exist for their detection/identification. The pests are listed in Annex IIAI of Directive 2000/29/EC as Elsinoë spp.
