SPIDER MITE DETECTION IN COTTON USING HYPERSPECTRAL REMOTE SENSING The strawberry spider mite (Tetranchus turkestani) is a serious pest in California cotton and causes reddish discoloration on leaf surfaces that may be detectable through remote sensing. Once mite populations reach a critical threshold the entire field is typically sprayed with pesticide. If outbr... Effect of Plastic Tarps Over Raised-beds and Potassium Thiosulfate in Furrows on Chloropicrin Emissions from Drip Fumigated Fields Plastic tarps are commonly used in raised bed strawberry production to minimize emissions of preplant soil fumigants and are left in place throughout the growing season as part of the standard cultural practices. Use of tarps with lower permeability or soil amendments with chemical such as thiosulf... Performance of Low Permeable Tarps on reducing 1,3-dichloropropene and Chloropicrin Emissions in a Strawberry Field Trial Low permeable tarps have great potential to reduce fumigant emissions in strawberry fields with raised beds. A field study was conducted in fall 2007 near Oxnard, CA to compare the emission reductions efficiency of two low permeable tarps [virtually impermeable film (VIF) and semi-impermeable film (... STRAWBERRY FRUIT PROTEIN WITH A NOVEL POST-TRANSLATIONAL INDOLE-ACYL MODIFICATION. Although the importance of auxin in development and ripening of strawberry (Fragaria) fruit is well established, little is known about auxin metabolism in strawberry, or auxin functions in these important agricultural processes. Auxin is found in both free and conjugated forms. We found that achene... THE USE OF REVERSE TRANSCIPTASE FOR EFFICIENT FIRST AND SECOND STRAND CDNA SYNTHESIS FROM DSRNA TEMPLATES Molecular characterization of eight distinct, difficult-to-clone, RNA plant viruses was accomplished after the development of a reverse transcriptase-based first- and second-strand cDNA synthesis method. Double-stranded (ds) RNA templates isolated from strawberry and blackberry, as well as from sev... EFFECTS OF BIOLOGICALLY DERIVED PRODUCTS ON MOBILITY AND REPRODUCTION OF THE ROOT LESION NEMATODE, PRATYLENCHUS PENETRANS, ON STRAWBERRY Biological products reported to have nematotoxic effects were evaluated for the suppression of P. penetrans mobility in vitro and reproduction on strawberry plants. Mobility was evaluated by exposing nematodes to a range of concentrations of products in aqueous solutions for 24, 48, and 72 h, follo... EVALUATION OF NATIVE STRAWBERRY GERMPLASM FOR RESISTENCE TO ANTHRACNOSE Anthracnose diseases of strawberry are caused by several Colletotrichum species. A subset ("supercore") of the Fragaria core collection maintained at the USDA National Clonal Repository, Corvallis, OR, contains an elite group of 15 native F. virginiana clones and 12 F. chilo... PRE AND POST-INFECTION ACTIVITY OF PYRACLOSTROBIN FOR CONTROL OF ANTHRACNOSE FRUIT ROT OF STRAWBERRY CAUSED BY COLLETOTRICHUM ACUTATUM Anthracnose fruit rot, caused by Colletotrichum acutatum, is a serious problem for production of annual strawberries in central Florida and worldwide. The efficacy of pre- and post-infection applications of pyraclostrobin (Cabrio EC) was evaluated under field conditions over two seasons in Florida. ... STRAWBERRY LATENT VIRUS: A POTENTIAL LINK BETWEEN PLANT AND INSECT VIRUSES More than two decades ago, a number of laboratories studied strawberry mild yellow edge disease (SMYED) and tried to verify the presence of a luteovirus that was anecdotally associated with it. Martin and Converse purified a spherical virus from a SMYE diseased plant, but later found similar particl... FUNGICIDE MANAGEMENT OF FRUIT DISEASES OF STRAWBERRY IN LOUISIANA AND MISSISSIPPI Fungicide studies were conducted at Hammond, LA and Poplarville, MS during the 2002 and 2003 fruiting seasons. Ten (MS) or 13 (LA) fungicide treatments were applied at 7-10 day intervals to the strawberry cultivars, Camarosa (LA), Chandler (MS) and Pelican (MS). Berry diseases were identified and ...       Last Modified: 11/25/2009 ARS Home | USDA.gov | Site Map | Policies and Links  FOIA | Accessibility Statement | Privacy Policy | Nondiscrimination Statement | Information Quality | USA.gov | White House
