“…Major important diseases in sorghum were MStV and anthracnose (Indira et al, 2002;Narayana et al, 2002). MStV incidence was highly genotype-dependent with genotypes ICSV 93046, M 35-1 and ICSV 745 showing high, medium and low susceptibility to MStV, respectively ( Table 2).…”

“…These two foliar diseases prematurely defoliate plants, leading to losses in pod and haulm yield. As summarised from field survey reports (Navi et al, 2001), anthracnose, caused by Colletotrichum graminicola, and maize stripe viral disease (MStV), caused by a tenuivirus, are prevalent diseases of sorghum in most parts of India (Indira et al, 2002;Narayana et al, 2002). Anthracnose can attack all plant parts.…”

“…MStV systemically infects plants causing stunting. Depending on the growth stage at which infection occurs, infected plants either do not produce panicles or set few seeds if panicles are produced (Narayana et al, 2002). The virus is persistently transmitted by the plant hopper Peregrinus maidis, which is also a key pest of sorghum (Narayana et al, 2002).…”

Crop residues from groundnut and sorghum constitute important fodder resources for dairy production and fodder trading on the Deccan Plateau in India. This paper addresses the effect of important diseases of groundnut and sorghum on pod and grain yield and crop residue yield and quality. In four genotypes of groundnut, late leaf spot (Phaeoisasariopsis personata) and rust (Puccinia arachidis) are the two major foliar diseases that together could reduce pod and haulm yield by 70% and in vitro digestibility of haulms by 22%. Two genotypes (ICGV 9202 and 92093) were highly resistant to these foliar diseases maintaining high pod and haulm yield as well as high in vitro digestibility of haulms (>62.3%) even under highest disease pressure. Important diseases in sorghum investigated were a viral disease caused by maize stripe virus (MStV) and anthracnose caused by Colletotrichum graminicola. MStV reduced grain yield by 30%, stover yield by 42% and digestible stover yield by 45%. Effects of MStV were highly genotype-dependent and grain and stover were affected in different ways in different varieties. The choice of appropriate genotype for a given farming situation will depend on trade-off scenarios for benefits from grain and stover. Similarly, anthracnose could reduce grain yield by 47% and stover yield by 23% but effects on stover quality were variable. As observed for MStV, effects of anthracnose were highly genotype-dependent and genotypes were identified that maintained high grain and stover yield under high disease pressure.

“…The buoyant density is 1.35 g cm -3 in CsCl. It is a positive-sense monopartite single-stranded RNA-containing virus which encodes for a single protein of about 350 kDa [78,79,80]. It produces mosaic and red-leaf symptoms in sorghum.…”

Viruses infecting sorghum are widely distributed in Asia and Africa and are of economic importance. In recent years, apparent virus disease incidence has increased, probably due to changes in agricultural practices associated with the introduction of hybrids and new varieties that are being developed and released continuously. The first virus disease described on sorghum in the world was Sugarcane mosaic virus (SCMV). Nigeria is one of the leading sorghum producing countries in the world and most of its populace in the northern part depend on sorghum as their primary staple food and so far, seven viruses have been identified on sorghum in Nigeria: Maize mosaic virus (MMV), Maize stripe virus (MSpV), Maize streak virus (MSV), Sugarcane mosaic virus (SCMV), Guinea grass mosaic virus (GGMV), Sorghum mosaic virus (SrMV) and Maize dwarf mosaic virus (MDMV). This calls for proper molecular characterization and deployment of management strategies of the diseases the viruses incite. Future research needs are discussed.

“…M 35-1 alone covers over 70% of the area under post -rainy sorghum in India. Narayana and Muniyappa (1995) and Narayana et al (2002) have indicated MStV causes substantial losses in vegetative growth and grain yield of sorghum in India. Recently, Pande et al (2003) and Navi et al (2003) have shown loss in grain and stover yields with variability in digestibility (%) of healthy and MStV infected plants.…”

Extensive on-farm disease surveys were conducted from August 1999 until March 2001 in four sorghum-growing states of the Indian Deccan plateau. A total of 965 fields were surveyed covering 228 fields in Andhra Pradesh (AP), 406 in Karnataka (KAR), 290 in Maharashtra (MH) and 41 in Tamil Nadu (TN). Among 14 foliar diseases observed, maize stripe virus (MStV), a tenuivirus transmitted by the delphacid plant hopper (Peregrinus maidis), and among five panicle diseases, ergot or sugary disease (Claviceps sorghi and C. africana) were the most destructive diseases. MStV was prevalent in 28.4% and ergot in 13.4% of the fields surveyed in two years across four states. Yet, the mean incidence of MStV in AP was 6% with 85% mean severity. The values in KAR were 12% incidence and 83% severity, in MH 5% and 67%, and in TN 12% and 76%, respectively. The mean incidence of ergot in AP was 34% with 67% mean severity. The values in KAR were 41% and 79%, in MH, 30% and 67%, and in TN 100% and 100%, respectively. Variation in frequency of occurrence of MStV was observed between 1999 and 2001. Variations in frequency could be due to weather factors, vector survival, cropping pattern, and host specificity. The frequency of ergot also was varying among years, locations, seasons and cultivars. An ergot epidemic was observed during the 1999 rainy season in Maachinenipalli village (16835 0 N; 7883 0 E), Andhra Pradesh. In September 2000, the disease had spread to 13 neighboring administrative zones damaging about 130,000 ha. This paper elucidates the distribution of diseases observed between 1999 and 2001 but does not imply that the diseases are restricted necessarily to a particular zone or location.
