BACKGROUND The potato psyllid is a serious pest of potatoes. Sampling plans on potatoes for the potato psyllid have yet to be developed, thus the authors' objectives were (1) to determine the most efficient within-plant sampling unit, (2) to determine the spatial dispersion of potato psyllids in potato fields and (3) to develop a binomial sequential sampling plan for this pest. RESULTS Signif...

We reported a case of anesthetic treatment of appendicectomy to a patient under potato poisoning. The overview of potato poisoning has been reviewed in the report and the symptom of the patient under potato poisoning comparing with other appendicitis patients has been described. We highlighted the deference of methodology of anesthetic treatment comparing the patient under potato poisoning with...

Purple potatoes were used as raw material to study the purple potato wine production process and antioxidant activity. This paper analyzed different fermentation time, fermentation temperature, yeast inoculum, initial pH, the initial sugar content on alcohol and anthocyanin contents of purple potato wine by single factor experiments and response surface methodology(RSM). The results showed that...

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...

In the agriculture industry, adventitious root formation is a core issue of plants asexual propagation. However, the underlying molecular mechanism of adventitious root formation is far beyond understanding. In present study we found that target of rapamycin (TOR) signaling plays a key role in adventitious root formation in potato and Arabidopsis. The core components of TOR complex including TO...

Potato has a variety of reproductive uniquenesses besides its clonal propagation by tubers. These traits are controlled by a different kind of genetic control. The reproductive information has been applied to enable interspecific hybridization to enhance valuable traits, such as disease and pest resistances, from the tuber-bearing Solanum gene pool. While progress has been made in potato breedi...

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...
