Plant health care in organic farming – The role of natural substances in a biodiversity-based system approach
One of organic agriculture’s defining traits is its approach towards plant health care, relying mainly on preventive and indirect measures within the agroecosystem. As a last resort, organic farmers can combine these with direct measures, if these are based on the use of natural substances. The principles of organic agriculture seek to prevent the introduction […]
Functional biodiversity: Mediterranean plants to improve natural enemies in organic citrus
Resurgent pests or invasive exotic pests (e.g., two new species of mealybugs, or the Trioza erytreae, transmitter of the Huanglongbing disease (HLB)) are major challenges of the Mediterranean citriculture). The solution could be to increase the presence and prevalence of natural enemies of pests through the introduction of plant biodiversity such as perimeter hedges, ground […]
Use of Copper-Based Fungicides in Organic Agriculture in Twelve European Countries
The reduction of copper-based plant-protection products with the final aim of phasing out has a high priority in European policy, as well as in organic agriculture. Our survey aims at providing an overview of the current use of these products in European organic agriculture and the need for alternatives to allow policymakers to develop strategies […]
Reynoutria sachalinensis extract elicits SA-dependent defense responses in courgette genotypes against powdery mildew caused by Podosphaera xanthii
Powdery mildew (PM) caused by Podosphaera xanthii is one of the most important courgette diseases with high yield losses and is currently controlled by fungicides and sulphur applications in conventional and organic production. Plant derived elicitors/inducers of resistance are natural compounds that induce resistance to pathogen attack and promote a faster and/or more robust activation of plant […]
