Combinations of treatments to replace the use of conventional fungicides for the commercial control of postharvest diseases of citrus fruit

Evaluation of sodium benzoate and other food additives for the control of citrus postharvest green and blue molds

“…Consequently, the citrus industry worldwide is increasingly demanding for alternatives to conventional fungicides to control postharvest diseases. In the last few years, many studies have been published and reviewed on alternatives to synthetic fungicides for the control of postharvest decay of fresh horticultural produce (Palou et al, 2008;Cunningham, 2010;Janisiewicz and Conway, 2010;Montesinos-Herrero and Palou, 2010;Romanazzi et al, 2012;Bautista-Baños, 2014). Among them, dip treatments with low toxicity substances with antimicrobial properties has been one of the first approaches (Hall, 1988), since the substitution of synthetic fungicides by these products would not require substantial changes in the industrial procedures followed in the packinghouses.…”

Wound responses of wild apples suggest multiple resistance mechanism against blue mold decay

“…Significant progress has been made in finding alternatives to synthetic fungicides during the past three decades including biological control, substances generally regarded as safe (GRAS), and various physical treatments (Janisiewicz and Korsten, 2002;Lurie et al, 1998;Ramanazzi, et al, 2012;Soliva et al, 2014;Wilson et al, 1994). In general, these alternatives do not have as wide a spectrum of activity and curative ability as the synthetic fungicides; however, in combination they can provide consistent control under a broad spectrum of conditions often rivaling the Janisiewicz et al Wild apple resistance 3 synthetic fungicides (Cunningham, 2010;Janisiewicz and Conway 2011). Thus, the combination of a moderate level of resistance in the fruit to postharvest decays with biocontrol agents or other alternatives may tilt the balance against the pathogens and result in adequate control of decay.…”
