The Guthion-resistant strain of walnut aphid parasite, Trio x y s p a II i d us. was mass reared in the greenhouse on potted walnut trees and released into five commercial walnut blocks near Colusa, Stockton, Modesto, and Hanford. Parasites successfully established in four of the five sites, surviving on field rates of Guthion and Supracide. The Guthion-resistant strain persisted in the release...

Sixteen streams in middle and eastern Tennessee were surveyed for the sudden oak-death pathogen Phytophthora ramorum 2010-2012. Surveys were conducted in the spring and fall using healthy Rhododendron leaves, and a total of 354 oomycete isolates were recovered. Sequence analysis of the ITS region provisionally identified 151 Phytophthora, 200 Pythium, two Halophytophthora and one Phytopythium. ...

A comprehensive phylogeny representing 142 described and 43 provisionally named Phytophthora species is reported here for this rapidly expanding genus. This phylogeny features signature sequences of 114 ex-types and numerous authentic isolates that were designated as representative isolates by the originators of the respective species. Multiple new subclades were assigned in clades 2, 6, 7, and...

in this research, chemical composition, gas production characteristics, effective degradability and nutritive value index (nvi) of dm and cp by in situ method of treated walnut hull by nurospora sitophila were studied. three fistulated kermani ram were used for determination of walnut hull degradability. data were analysed using completely randomize design. by processing walnut hull with neuros...

walnuts are one of the most important nut crops worldwide. the area under cultivation increases every year. in 2008, the food and agriculture organization reported exports of about $17.1 billion. the country of iran is the 4th largest producer of walnuts in the world. stages from production to consumption are very important, because the condition and quality of the shelled nutmeats affects the ...

In July 2000, the fi nger of blame for a mysterious mass killer of Californian oak trees came to rest on a previously undescribed plant pathogen. From the initial identifi cation of Phytophthora ramorum, it took less than four years to produce a draft sequence of its genome, one of the fastest-ever discovery-to-sequence stories for a complex pathogen. This achievement was a United States initia...

There are more than 60 species in the genus Phytophthora (94), and most are destructive plant pathogens. Extensive efforts are directed at the control of Phytophthora diseases each year, yet they still cause serious crop losses. For example, more than $200 million in lost production annually is attributed to Phytophthora diseases in Australia alone (47). Late blight, caused by P. infestans, pro...

Two distinct Phytophthora taxa were found to be associated with brown rot of pomelo (Citrus grandis), a new disease of this ancestral Citrus species, in the Vinh Long province, Mekong River Delta area, southern Vietnam. On the basis of morphological characters and using the ITS1-5.8S-ITS2 region of the rDNA and the cytochrome oxidase subunit 1 (COI) as barcode genes, one of the two taxa was pro...

milk and dairy products are in diet almost every day. milk fat contains 70% of saturated fatty acids which can cause an increase in total and low-density lipoprotein cholesterol, and the risk of cardiovascular diseases. therefor, modification of fat composition at dairy products such as yoghurt seems necessary. walnut has high amount of essential fatty acids, anti oxidants and other beneficial ...
