Characterization of Resistance to Squash Silverleaf Disorder in Summer Squash
Feeding nymphs of the silverleaf whitefly, Bemisia argentifolii (formerly known as Bemisia tabaci Gennadius, B strain), cause a physiological disorder known as squash silverleaf (SSL) in summer squash (Cucurbita pepo L.). This disorder is characterized by a progressive silvering on the upper leaf surface caused by the development of large air spaces between the palisade mesophyll cells and the ...
متن کاملRelative susceptibility of peach rootstocks to crown gall and Phytophthora root and crown rot in Chile
G. Guzmán, B.A. Latorre, R. Torres, and W.F. Wilcox. 2007. Relative susceptibility of peach rootstocks to crown gall and Phytophthora root and crown rot in Chile. Cien. Inv. Agr. 34(1):31-40. Crown gall (Agrobacterium tumefaciens) and Phytophthora root and crown rot (PRCR), caused by P. cryptogea, are two major limiting factors affecting peach (Prunus persica) production in Chile. At present, N...
متن کاملSuppression of Phytophthora Root Rot in Red Raspberries with Cultural Practices and Soil Amendments
Various soil amendments and cultural practices were examined in both a phytophthora-infested (Phytophthora fragariae var. rubi) (+PFR) and uninfested fi eld (–PFR) planted to ‘Heritage’ red raspberries. Although plants in the +PFR fi eld did not exhibit typical disease symptoms due to unseasonably dry weather, their growth was less than those in the –PFR fi eld. After 2 years, plants in the +PF...
متن کاملDetermining Phytophthora Resistance in Elite Paradox Clones and Specific Etiology of a Paradox Crown and Root Rot
The objectives of this research are: (1) to evaluate elite Paradox hybrid clones for resistance to Phytophthora citricola, a virulent and prevalent crown and root pathogen affecting California walnuts and (2) to determine specific etiology of a root and crown rot problem in upper Sacramento Valley orchards on Paradox walnut rootstock. Two screens for resistance to P. citricola were completed in...
متن کاملStop the Rot! Using Cultural Practices to Reduce Bacterial Bulb Decay in Onions
Narrow plant spacing reduced bacterial bulb decay by 53 to 64% Do you know how easy this is? A simple modification to adjust your planting configuration is all it would take to drastically reduce losses from bacterial bulb decay. Our studies showed that when plant spacing was reduced from 6 or 8 inches to 4 inches with 3 or 4 rows per 3-foot plastic mulch bed (row spacing: 4 rows = 6 inch; 3 ro...
