Publikasjoner
NIBIOs ansatte publiserer flere hundre vitenskapelige artikler og forskningsrapporter hvert år. Her finner du referanser og lenker til publikasjoner og andre forsknings- og formidlingsaktiviteter. Samlingen oppdateres løpende med både nytt og historisk materiale. For mer informasjon om NIBIOs publikasjoner, besøk NIBIOs bibliotek.

Common scab (CS) is an important disease and quality problem in potato crops worldwide. CS degrades the appearance of the potato tubers, thereby diminishing market value. Knowledge of CS has expanded considerably over recent years, enabling improved detection of the causal pathogens and increased understanding of mechanisms of pathogenicity, and providing potential methods of modulating pathogen response for disease resistance. However, effective control of this disease remains elusive, and will require increased understanding of both the host and the pathogen. Traditional control strategies such as irrigation and reduced soil pH are not sufficient and often fail. Optimizing environmental conditions for reduction of CS can also lead to favorable conditions for other diseases. The most desirable control method would be disease-resistant potato cultivars. However, no currently available commercial potato cultivar has been shown to be completely resistant to CS. In this review, we provide an overview of potato CS caused by plant pathogenic Streptomyces species, recent research on mechanisms and management of the disease, and knowledge gaps that limit successful control of this ubiquitous and troublesome disease.

The agro-ecosystems (e.g. cropping system (tunnel/ greenhouse/ open field, etc.), plant species, cultivar, soil management (fertilization, pH, soil cover, etc.)) has an impact on pests (insects, mites, snails, nematodes, plant diseases and weeds) and the control strategies used. Biological control agents (BCA) can serve as alternatives or as supplements to chemical pesticides. They can reduce the need for chemical treatments and thus the risk of non-target effects to humans and the environment from pesticide use. Further, the use of BCA might help to reduce the risk of pesticide resistance development. The Regulation and use of BCA differs significantly between different European countries, especially for the macroorganisms (insects, mites and nematodes). Norway has its own regulation for macroorganisms, while regulation of microorganisms (fungi, bacteria, viruses and protozoa) is almost the same as for chemical pesticides, and is comparable to the EU regulations. There is a wide range of biological control products available on the international market, and access to these products would benefit Norwegian growers. Norway has, however, a very limited selection of registered biological control products. A new Norwegian project titled “Increasing the use of biological control agents of plant pests” is financed by the Norwegian Ministry of Agriculture and Food. In this project we try to identify the bottlenecks and propose solutions to promote the registration and increase the use of BCA in Norway. A survey has been conducted where experts and agricultural advisors on different cropping systems were asked to prioritize which BCA (products) on the European market should be promoted and registered in Norway (initially against pest insects and mites). Preliminary results from this project will be presented.
