Control of sorghum downy mildew of maize and sorghum in Africa
2000
Bock, C.H. | Jeger, M.J. | Cardwell, K.F. | Mughogho, L.K. | Sherington, J.
In Africa, sorghum downy mildew (SDM), caused by Peronosclerospora sorghi, infects both sorghum and maize. Systemic infection can result in severe yield loss. The effects of seed treatments and foliar sprays of metalaxyl on the disease were determined on maize in Nigeria (1992) and sorghum in Zimbabwe (1993/4). Seed treatment at 1.0 g a.i/kg or a foliar spray at 0.96 g a.i./l significantly reduced the incidence of the disease, although the latter was less consistent. The effect on yield was less clear. In Nigeria, severe stem borer damage in some plots prevented definitive yield assessment in response to fungicide. In Zimbabwe, there was no effect of fungicide on sorghum yield due to the overriding influence of insect damage (1993) and drought (1994). Planting density of sorghum in Zimbabwe did not appear to influence disease incidence at the densities used. Metalaxyl can be used to control SDM effectively on sorghum and maize in Africa.

Arya, R.L. (I.I.P.R., Kanpur (India) | Nirannjan, K.P. | Singh, A. | Singh, J.B. (Indian Grassland and Fodder Research Institute, Jhansi (India))
A field experiment was conducted during rainy (kharif) season of 1993-94 to 1995-96 at the Indian Grassland and Fodder Research Institute, Jhansi to study the different food-fodder cropping systems and manurial schedules under rainfed conditions. Significantly higher grain and stover yields of sorghum were obtained in sorghum + pigeonpea/Cenchrus setigerus intercropping system compared with that in sorghum + cowpea intercropping system. Sorghum + cowpea intercropping produced significantly more green fodder and dry-matter yields of fodder crops than sorghum + grass strips plots. Sorghum grain-equivalent yield was more in sorghum + pigeonpea followed by sorghum + cow pea and sorghum + grass strips plots. Among the different manurial schedules, combined application of organic and inorganic sources of plant nutrients produced significantly higher grain and stover yields of sorghum, green fodder and dry-matter yields of fodder crop as well as sorghum grain-equivalent yield compared with 100 through inorganic fertilizers application. The survival of trees under rainfed condition was 84.3 after 20 months of their establishment. The tree attained 103.4 cm height and 1.33 cm collar diameter under rainfed condition.
