| The effectiveness of Benomyl sprays (270 g a.i./ha) for controlling yellow spot disease in the profusely flowering susceptible variety S17 was evaluated under severe epiphytotic conditions. Sprays applied with mist blowers at intervals of 1, 3 and 4 weeks were compared. There were no differences between treatments at 3- and 4-week intervals. Although they did not control infection as well as weekly sprays, they were nearly as effective in giving a substantial increase in sucrose content. Spraying also improved juice purity but had no effect on cane yield at harvest early in the season. There was a greater response to fungicide control of flowered that in vegetative cane at harvest time. In an industrial trial, four fungicide sprays with mist blowers at intervals of 5 weeks gave 57 per cent control of infection and an increase in sugar yield to 1 to 2 tons/ha. Disease control was also effective when Benomyl was applied above the leaf canopy with ULV sprayers. Therefore, fungicidal control of yellow spot in sugarcane could be fe asible and economic and can be a useful temporary measure to re duce losses in case of change of resistance in varieties, pending their replacement. | |
