The efficacy of Trichoderma harzianum strain DGA01, sodium carbonate (SC), sodium bicarbonate (SBC) and sodium hypochlorite (SH) applied alone or in various combinations was evaluated in vitro against the most important postharvest pathogens of banana such as Lasiodiplodia theobromae, Thielaviopsis paradoxa, Colletotrichum musae, and Fusarium(More)
Lasiodiplodia theobromae, Thielaviopsis paradoxa, Colletotrichum musae, C. gloeosporioides, Fusarium verticillioides, and F. oxysporum were screened in vitro for sensitivity to Na2CO3, NaHCO3, CaCl2, NaCl, and NaClO. The spore germination of all pathogens was completely inhibited by Na2CO3 4 g/l, NaClO 5 g/l, and NaHCO3, CaCl2, and NaCl 6 g/l each. Dipping(More)
The fungal population in the air and on developing fruit on a nonchemical banana farm in the Philippines was estimated from January 1998 to December 2001 to follow the source, determine the origin, and establish the population dynamics of various fungi associated with postharvest diseases of banana. Forty fungal genera were found in the air on a nonchemical(More)
The present study aimed at improving the control of crown rot disease and quality of pesticide-free banana banana fruit by integrated approach combining Bacillus amyloliquefaciens DGA14 and hot water treatment (HWT). The efficacy of treatment combination was tested on cultures of crown rot-causing pathogens, Lasiodiplodia theobromae, Thielaviopsis paradoxa,(More)
In 2012 to 2014, Philippine green coffee beans from Coffea arabica in Benguet and Ifugao; Coffea canephora var. Robusta in Abra, Cavite, and Ifugao; and Coffea liberica and Coffea excelsea from Cavite were collected and assessed for the distribution of fungi with the potential to produce ochratoxin A (OTA). The presence of fungal species was evaluated both(More)
Samples of Theobroma cacao seedlings and mature trees with vascular streak dieback (VSD)–like symptoms were observed in Davao, Philippines in 2014. The symptoms were chlorosis and later necrosis of leaves, mostly those second or third from the stem tips. Abscission of these leaves occurred within 2 or 3 days of the first appearance of symptoms. Swelling of(More)
