Effects of low temperature phosphine fumigation on postharvest quality of white chrysanthemum ‘Dabaiju’

Toxicity of Phosphine Fumigation Against <I>Bactrocera tau</I> at Low Temperature

“…Phosphine gas free of ammonia was generated by the reaction of aluminum phosphide tablets (Nippon Kasei Co. Ltd, Japan) and 5% (vol:vol) solution of sulfuric acid, as previous described (Zhang et al 2012). The content of phosphine in the generated gas was determined by the spectrophotometric method, based on the reaction of phosphine with silver nitrate in aqueous solution to form an egg-yellow chromophore with an absorption maximum at 400 nm (Rangaswamy 1984).…”

“…In recent years, pure phosphine that is free of ammonia has been successfully used to control aphids, western ßower thrips, peach fruit moth, and leafminer in strawberry, lettuce, broccoli, apples, and carnations at low temperatures (Horn et al 2005, Liu 2008, Liu et al 2010, Zhang et al 2014. Moreover, Chinese white chrysanthemum "dabaiju" (Dendranthema morifolium Tzvel) exhibited no phytotoxic symptoms after phosphine fumigation at a dose of 3.04 mg/liter for 8 d at 2ЊC (Zhang et al 2012). Therefore, it is reasonable to explore the efÞcacy of phosphine fumigation against pests with quarantine signiÞcance.…”

Transcriptional inhibition of the Catalase gene in phosphine-induced oxidative stress in Drosophila melanogaster

“…PH3 was generated using aluminum phosphide tablets in acidified water [24]. The content of PH3 was determined by a spectrophotometric method [25].…”

Effect of different phosphine gas concentrations against Frankliniella occidentalis (Pergande, 1895) (Thysanoptera: Thripidae) on tomato and green pepper fruit, and determination of fruit quality after application under low-temperature storage conditions

“…Also, chemical control of this pest under field conditions is very difficult because it is a polyphagous and multivoltine pest. For the last few decades, either pure phosphine gas alone or combination with CO2, has been tested for postharvest fumigation of fresh food products such as apple, broccoli, cut flowers, lettuce, grape, peach, pear, plum, paprika, and white chrysanthemum under cold weather conditions (Liu, 2008;Zhang et al, 2012;Rogers et al, 2013;Emekci et al, 2014).…”
