Abstract


‘Melomas’, a new pomelo clone (Citrus grandis) was introduced to the public in 1998 by MARDI. Several pilotprojects involving the planting of Melomas were conducted to further promote this pomelo clone. One of theseprojects was conducted in Stesen MARDI Kuala Kangsar, Perak and as a result, healthy and vigorous pomelo treeswere grown. In 2007, the pomelo trees managed to produce an abundance of flowers, but surprisingly the fruitsetting had died and almost no harvesting was done. A very low harvest was reported due to an occurrence offungus in numerous locations in Northern Perak in 2007 and 2008. A study was conducted beginning fromJanuary 2007 to December 2011 to tackle this phenomenon. It was noticed that every flowering season coincidedwith high daily rainfalls. The relatively high humid conditions had increased the incidence of Anthracnoseinfection that caused the young flower bud to die and undeveloped fruit sets to drop unattainably. The heavyrainfall severely prolongs raindrop smears on the flower fruit set. Almost every Melomas grower faced the samepredicament. This case study was designed to intervene and stop the causal fungus infection brought by the rain.Transparent plastic covers (TPC) were introduced to prevent raindrops from continuously smearing the flowerbunch. It was stapled onto the branch above the bunch of flowers to form a small half cylinder plastic roofing thatprevents the raindrop falling onto the small fruits. To tackle the problem, a series of workshops and technologytransfer seminars were arranged for the Melomas growers by the MARDI extension personnel. The results showedthat the manipulation of the microenvironment around the flowers had helped the grower to recover andeventually increase the Melomas yield. It was observed that this low-cost technique had significantly increased thenumber of Melomas fruit sets as opposed to the control treatment (without plastic covers). This technique hadbeen practiced by local pomelo farmers in Padang Rengas, spanning over an area of 35 ha and it is being practicedin a pilot project at MARDI Kuala Kangsar. It has a proven 85% success rate and has been reported to significantlyboost the productivity in the area.
