Rong-Rien) Fruits Treated with Preharvest Application of Trichoderma harzianum and Chelated Calcium 2012 tables ; references The effect of preharvest spraying of Trichoderma harzianum and chelated calcium on the quality of rambutan (Nephelium lappaceum L.) fruits and the control of fungal diseases during storage was investigated. Trichoderma harzianum Rifai (4.8 × 108 conidia mL-1) and chelated calcium (5.63 mg L-1), either alone or in combination, were sprayed at 3-wk intervals three times onto rambutan trees 4 wk after fruit set. After harvest, fruits were separated into two groups: one group was subsequently stored in 0.04-mm low-density polyethylene bag at 12 °C for 16 d, and another set was artificially wounded and inoculated with the pathogenic fungi Lasiodiplodia theobromae, Colletotrichum gloeosporioides and Gliocephalotrichum microchlamydosporum, covered with plastic wrap and incubated at 28 °C for 5 d. The fruits were evaluated after storage for 16 d at 12 °C. Postharvest decay incidence and severity significantly decreased in fruits from the trees treated with both T. harzianum and chelated calcium. Moreover, T. harzianum and chelated calcium also reduced populations of the three plant pathogenic fungi on the fruit. The treatment did not also differ from those of the trees treated with carbendazim. Both the chelated-calcium treatment and its combination with T. harzianum also resulted in the lowest weight loss and browning, the highest accumulation of calcium in the peel and spintern, and the thickest peel. T. harzianum and chelated calcium treatments did not affect the total soluble solids, titratable acidity and ascorbic acid content.
