The distribution of the fungicide Benlate on the leaves of sugarcane vars. S17 and M13/56 after application by helicopter was assessed. Spraying was performed by a Bell 45 G helicopter fitted with a combination of D8 and D10 hollow cone nozzles (Spraying Systems Co.) with D45 whirl plates. Application rate was 70 l/ha at 32 psi and droplet size was in the range of 350 to 750 µm. The flying speed was 88 kph and spraying was at 2 metres above the cane canopy. A phosphorescent chemical was added to the spray mixture. The fungicide was found over the ten uppermost leaves of both varieties but distribution was better in M13/56. No difference was found between the coverage of flowered and vegetative canes in variety S17. The distribution of the chemical, which has a translaminar action, was considered to be adequate for satisfactory control of yellow spot diseases. | |
