Technique in producing off-season mango has been adopted in Thailand since 1986. Paclobutrazol, plant growth retardant, was used in combination with thiourea for producing as well as breaking of flower buds. Experiments were conducted on the application methods and it was found that soil drenching is more effective for the induction of flowering in mango as compared to foliar spray. The rate of paclobutrazol application depended on the size of tree canopy as well as mango cultivars. For the common mango cultivars, the rate of paclobutrazol applied is generally determined by multiplying the diameter of tree canopy (expressed in meter) with 1.0-1.5 g of active ingredients of paclobutrazol. At 120 days after the application of paclobutrazol, 0.5 percent thiourea was sprayed to the tree for bud breaking, whereas most buds would develop into flower within 2 weeks. Using this method, inflorescences were visible within 2.5 to 4 months after the paclobutrazol application depending on cultivar. However, the success in producing off-season mango is also dependent of other factors such as climatic conditions, mango cultivars, orchard mangement and the most importance is the experience of mango growers. At present induction of flowering in mango is not the major problem in Thai growers, as they can control the flowering in the on-season and off-season times. The other problems of mango production that need further researches are few or none fruit set and pre-harvest fruit drop in both on-season and off-season production.
