“…The In achieving the objectives of the quantitative and monetary losses studies, two varieties of sugar cane, Co 957 and Bida local, of known susceptibility to S. scitamineum (Obakin, 1978;Wada et al, 1998 and1999a) were evaluated from 1998 to 2000.…”

“…Many sugar cane diseases and pests reported in different parts of the world have also been reported in Nigeria (Wada, 1997;Sivanesan and Waller, 1986;Boboye, 1986). They include whip smut, red rot, leaf blast, sugar cane mosaic, pineapple disease, ratoon stunting disease, leaf scald, mottled stripe, pokkal boeng, sugar cane wilt disease (Sivanesan and Waller, 1986;Wada et al, 1999a). Wada (1997) and Wada et al (1998 and1999b) listed whip smut as the most important disease of sugar cane in Nigeria.…”

The yields of two sugar cane varieties Bida local and Co 957 were reduced by varying concentrations of Sporisorium scitamineum [M. Piepenbr., M. Stoll & Oberw. 2002 (Syn: Ustilago scitamiea H. & P.Sydow)], the causal organism for whip smut of sugar cane at Badeggi (lat. 9°045' long. 6°07'E at an altitude of 70.57m. a. s. l). The two varieties of sugar cane were inoculated with four levels of S. scitamineum inoculum, 0 × 10 6 , 2 × 10 6 , 4 × 10 6 teliospores/ml respectively and planted in a split plot design in four replicates between 1998 and 2000. Results showed that their yields were significantly impaired by the effect of whip smut. The 6 × 10 6 teliospores/ml inoculum concentration recorded the least yield in the two test cane varieties. The yields of Bida local in all the two crop cycles from 1998 to 2000 were significantly lower than the yields of Co 957. Regressions of whip smut incidence on cane yields of Co 957 and 'Bida local' for two crop cycles showed that in both years, there was significant negative correlation between the incidence of whip smut and cane yield, except in 2000 on Co 957 ratoon crop. The highest yield reduction by whip smut was from the plant crop of Co 957 in 1998 and the ratoon crop of 'Bida local' in 1999 where each unit rise in whip smut incidence caused cane yield reduction of between 1.00-1.9 t/ha and 0.1-1.9 t/ha in Co 957 and 'Bida local' respectively. In monetary terms and at current rate of 1US$ to 200 Nigerian Naira (N200), the cane grower of the two cane types looses between $600-1140/t or N120,000-228,000 for Co 957 and $60-1140 or N12000-228,000 for 'Bida local' chewing cane. In the 1999 evaluation, each unit rise in incidence of whip smut reduced the yield of Co 957 by 0.

“…Globally different measures are applied for the avoiding and control of sugarcane smut (Sundar et al, 2012), such as hot water treatment, rouging out diseased plants, planting resistant or tolerant cultivars, and application of fungicides (Gupta, 1979;Agnihotri, 1983;Ferreira & Comstock, 1989;Fauconnier, 1993;Wada et al, 1999;Rott et al, 2000). Fungicides not only eradicate smut from the planting material, but also defend seed cane from infection of pathogen inoculum present in the planting soil (Firehun et al, 2009).…”

Whip smut of sugarcane is considered as the most important disease of sugarcane and occurrs in almost all sugarcane producing regions of the world, including Pakistan. In many cases, the use of the chemical fungicides becomes indispensable to combat destructive plant diseases, which otherwise cause heavy economical losses. Fungicides not only eradicate smut from the planting material, but also prevent re-infection when they are used as a pre-plant treatment of setts. During the present investigation, setts are inoculated with teliospores suspension of Ustilago scitaminea and treated with eleven different fungicides. Pre-inoculated setts are dipped for 30 minutes in hot fungicide solution, ambient fungicide solution. Hot and ambient water without fungicides serves as control. Most of the fungicide treatments significantly improved sett germination and check the smut development. For most of the quantitative and qualitative parameters, Bayleton, Bavistan and Tilt provide better results, as compared to the other fungicides. Based on the results we conclude that the effectiveness of fungicides increase more when applied as hot water fungicidal dip than ambient fungicidal dip.
