Abstract : An integrated disease management strategy for floral malformation of mango cv. Dashehari was developed in Uttar Pradesh, India, during 1998/99 and 1999/2000. The treatments comprised: pruning of malformed particles (T1); spraying 40 ppm mangiferin Cu2+ chelates (T2); spraying 40 ppm mangiferin Zn2+ chelates (T3); spraying 0.1% Bavistin [carbendazim] 50 WP (T4); spraying 0.05% phosphamidon 85 EC (T5); spraying 200 ppm NAA (T6); 2% urea spray (T7); T1 + T2 (T8); T8 + T3 (T9); T1 + T4 (T10); T1 + T5 (T11); T1 + T3 (T12); T12 + T5 (T13); T1 + T6 (T14); T14 + T5 (T15); T14 + T4 (T16); T1 + T7 (T17); T10 + T7 (T18); T11 + T7 (T19); T10 + T5 (T20); untreated (control). T20 had the lowest incidence of floral malformation during 1998/99 (15.1%) and 1999/2000 (10.7%). Data are also presented for number of hermaphrodite flowers, number of male flowers, panicle thickness and internodal distance.
