Carrot yellow leaf virus Is Associated with Carrot Internal Necrosis
Internal necrosis of carrot has been observed in UK carrots for at least 10 years, and has been anecdotally linked to virus infection. In the 2009 growing season some growers had up to 10% of yield with these symptoms. Traditional diagnostic methods are targeted towards specific pathogens. By using a metagenomic approach with high throughput sequencing technology, other, as yet unidentified cau...
متن کاملSusceptibility of the Carrot Weevil (Coleoptera: Curculionidae) to Steinernema feltiae, S. bibionis, and Heterorhabditis heliothidis.
Larvae, pupae, and adults of the carrot weevil (Listronotus oregonensis) were infected and killed by the three entomophagous nematodes (Steinernema feltiae, S. bibionis, and Heterorhabditis heliothidis) under controlled conditions. Third-stage larvae were more susceptible than pupae or adults. S. feltiae and S. bibionis were the most aggressive nematode species, causing larval mortality after 2...
متن کاملSweetening the Carrot
It is widely observed that many physicians working in public health facilities do not put in the required effort and/or time in their jobs. At the same time, many public physicians remain highly motivated, working long hours for little financial reward in providing quality health services. This mix of providertypes poses fundamental challenges in the design of compensation mechanisms and monito...
متن کاملBlack spot diseases in carrot
An important problem in organic carrot production in the Netherlands is the occurrence of black spots during storage. Several different fungal pathogens cause similar symptoms, which are collectively known as black spot diseases. We identified Alternaria radicina, A. dauci and Rhexocercosporidium carotae (syn. Acrothecium carotae) as the most prevalent black spot pathogens. We developed laborat...
متن کاملFree fatty acids in carrot-tissue preparations and their effect on isolated carrot mitochondria.
Mitochondria isolated from disrupted carrot tissue oxidize succinate more rapidly than all other substrates tested, have relatively high qo2 values, relatively low cofactor requirements and show respiratory control with ADP only when bovine serum albumin (1 %) is present in the homogenization medium. A protective effect of albumin during the isolation or incubation of mitochondria from insect (...
