Publication Type: Abstract Only Publication Acceptance Date: 2/25/1999 Publication Date: N/A Citation: N/A Interpretive Summary: Technical Abstract: Low temperature storage combined with sulfur dioxide slow release pads caused 100% mortality of omnivorous leafroller, Platynota stultana Walshingham, second instar (the least susceptible stage to low temperature storage) after 3 wks of exposure in table grapes, Vitis vinifera L. Temperatures in packed grape clusters decreased from ambient to 2C within approximately 2 d after placement in storage. Sulfur dioxide concentrations in grape clusters ranged between 0.2 and 1.0 ppm during the 1-6 wk storage period. The combination treatment uses existing packinghouse facilities and has potential to control the pest in table grapes for export. |
