6 7 8 9 Abstract 10 Cyanogenic glycosides are natural plant toxicants. Action by endogenous plant enzymes 11 can release hydrogen cyanide causing potential toxicity issues for animals including 12 humans. We have quantified amygdalin in seeds from different apple varieties, determined 13 the effects of processing on the amygdalin content of apple juice and quantified amygdalin 14 in commerciall...

Standard practice for grape disease management in Marlborough 10 years ago was to spray for diseases using calendar based spray programmes. Communication of grape disease management research has led to a change of practice for many grape growers. The key tool developed by the research programme was targeted spraying for diseases. This involved field monitoring for diseases and the use of decisi...

We used the California Pesticide Use Reports to study use of fungicides, bactericides, fumigants, and selected insecticides, primarily for vegetable, fruit, and nut production in California from 1993 to 2000. There were no obvious trends in decreased use of most compounds used to treat plant disease. However, growers have rapidly adopted recently introduced "conventional" compounds. There is ve...

Recent issues of ARE Update featured articles evaluating the failures of two California marketing cooperatives, Tri Valley Growers (TVG) and Rice Growers Association (RGA). Along with Blue Anchor’s dissolution and Calavo’s conversion, these combined events have created doubts about the future of cooperatives in California agriculture. Restructured forms of cooperatives are emerging. For example...

Abstract Background and Aims: Apple scar skin disease (ASSD) is one of the destructive diseases of pome fruits which is caused by ASSVd. Case presentation: We report molecular detection of ASSVd in symptomatic apples cv. Red Delicious with simultaneous presence of a new variant of HSVd from Khorasan Razavi province. Conclusion: This is the first report on the association of HSVd with...

The importance of speciation without the complete geographical separation of diverging populations (sympatric speciation) has become increasingly accepted. One of the textbook examples of recent speciation in sympatry is the apple maggot fly Rhagoletis pomonella, in which genetically differentiated host races feed on either hawthorn or apple. Three recent articles by Feder and collaborators sho...

Woolly apple aphid, Eriosoma lanigerum (Hausmann), has become a pest of increasing importance in Washington apple orchards in the past decade. The increase in aphid outbreaks appears to be associated with changes in pesticide programs and disruption of biological control. We sampled woolly apple aphid colonies in central Washington apple orchards for natural enemies of this pest from 2006 to 2...

The internal quality of apple is impossible to be detected by eyes in the procedure of sorting, which could reduce the apple’s quality reaching market. This paper illustrates an instrument using X-ray and machine vision. The following steps were introduced to process the X-ray image in order to determine the mould core apple. Firstly, lifting wavelet transform was used to get a low frequency im...

Apple has a lot on its plate at the moment with the release of the Apple Watch, but another major development for 2015 will be the unveiling of iOS 9. The latest Apple operating system will be expected to play a major role in the forthcoming iPhone 7, and Apple has traditionally released the latest version of its operating system well ahead of its flagship smartphone.
