Kløvertræthed - er nematoder årsagen?

Kløvertræthed forekommer ved, at især rodsårsnematoder angriber kløverens små rødder, og igennem de huller der herved opstår, kan svampe og bakterier komme ind i rødderne

Sen afpudsning begrænser angreb af kløversnudebiller

Hvidkløver til frø er usikker at dyrke - selv i konventionel produktion. Det er svært at opnå en passende tæthed af planter, undgå ukrudt og få afgrøden skårlagt og høstet under gunstige vejrforhold. Som økolog må man samtidig acceptere, at der er kløversnudebiller i marken. Og at billernes larver ernærer sig af hvidkløverfrø

Kløvertræthed: Er nematoder årsagen - og hvilke?

I de senere år har der været problemer med at etablere hvidkløver i kløverrige sædskifter. Denne kløvertræthed undersøges i et FØJOIII projekt. Foreløbige resultater tyder på, at rodsårsnematoden er en vigtig årsag. Dertil kommer svampe, som invaderer roden via de huller, som nematoden efterlader

Quality assessment of diagnosis and antibiotic treatment of infectious diseases in primary care:a systematic review of quality indicators

Objective: To identify existing quality indicators (QIs) for diagnosis and antibiotic treatment of patients with infectious diseases in primary care. Design: A systematic literature search was performed in PubMed and EMBASE. We included studies with a description of the development of QIs for diagnosis and antibiotic use in patients with infectious diseases in primary care. We extracted information about (1) type of infection; (2) target for quality assessment; (3) methodology used for developing the QIs; and (4) whether the QIs were developed for a national or international application. The QIs were organised into three categories: (1) QIs focusing on the diagnostic process; (2) QIs focusing on the decision to prescribe antibiotics; and (3) QIs concerning the choice of antibiotics. Results: Eleven studies were included in this review and a total of 130 QIs were identified. The majority (72%) of the QIs were focusing on choice of antibiotics, 22% concerned the decision to prescribe antibiotics, and few (6%) concerned the diagnostic process. Most QIs were either related to respiratory tract infections or not related to any type of infection. A consensus method (mainly the Delphi technique), based on either a literature study or national guidelines, was used for the development of QIs in all of the studies. Conclusions: The small number of existing QIs predominantly focuses on the choice of antibiotics and is often drug-specific. There is a remarkable lack of diagnostic QIs. Future development of new QIs, especially disease-specific QIs concerning the diagnostic process, is needed.KEY POINTS In order to improve the use of antibiotics in primary care, measurable instruments, such as quality indicators, are needed to assess the quality of care being provided. A total of 11 studies were found, including 130 quality indicators for diagnosis and antibiotic treatment of infectious diseases in primary care. The majority of the identified quality indicators were focusing on the choice of antibiotics and only a few concerned the diagnostic process. All quality indicators were developed by means of a consensus method and were often based on literature studies or guidelines

Organic clover seed production: Does intercropping with plant species with at strong scent distract the clover seed weevil and increase seed yield?

A field experiment was conducted in 1999-2001 in order to test if intercropping with other plant species with at strong scent would be able to distract clover seed weevils away from the clover seed field. Intercropping with chives, caraway, oregano or thyme did not have any effect on the number of clover seed weevils registered and white clover seed yield was not affected by any of the treatments. It is concluded, that a well-established white clover seed crop is very competitive against other plant species
