Approximately 200 sweet corn inbred lines were screened for two years for resistance to northern leaf blight, caused by Exserohilum turcicum, and Stewart's wilt, caused by Erwinia stewartii. Inbreds with the best levels of partial resistance to races 1 and 2 of E. turcicum included IL11d, IL676a, IL677a, IL685d, IL766a, IL767a and IL797a. Inbreds with the best partial resistance to E. stewartii included IL126b, IL676a, IL767a, IL772a, IL774g, IL797a, IL798a and M6011. Several of these resistant and moderately resistant inbreds had common ancestors; however, inspection of pedigrees suggested that resistance was derived from Puerto Rican, Bolivian, and other tropical sources and/or dent corn. Thus, many of the sweet corn inbreds may carry different genes for resistance and can be used for the development of populations with improved resistance.

Components of northern leaf blight resistance in maize due to race-specific resistance controlled by the Ht gene, partial resistance derived from inbred H99, and a combination of the two kinds of resistance, were studied subsequent to inoculation with Exserohilum turcicum race O. Lesion types, number of lesions (lesion number), percent leaf area affected (severity), and area under the disease progress curve (AUDPC) based on lesion number and severity were assessed in field studies conducted at two locations in Uganda and one location in Ohio in 1993. Lesion types observed were consistent for genotypes across locations. In general, significant differences among genotypes for data based on lesion number and severity were consistent for AUDPC based on lesion number and severity, respectively, at all locations. In Ohio, both Ht and partial resistance were effective in limiting disease development. In Uganda, susceptible inbreds (A619, A635, and B73) generally had higher severity than genotypes with partial resistance (H99, Mo17, and Babungo 3). However, there was a difference in response among genotypes depending on disease intensity at each location. Ht resistance and moderate partial resistance did not greatly affect lesion number at the higher disease intensity location, compared with the susceptible inbreds, but at the lower disease intensity location genotypes with partial resistance had fewer lesions than susceptible inbreds or the Ht conversions of the susceptible inbreds. At both plot locations, genotypes with partial resistance had lower severity than the susceptible inbreds or Ht conversions of the susceptible inbreds. Hybrids derived from crossing H99 with genotypes with moderate levels of partial resistance (Mo17 and Babungo 3) did not have significantly lower lesion numbers than hybrids of susceptible inbreds crossed with H99, but severity was significantly lower on these hybrids at the high disease intensity location. Results indicate that the level of partial resistance in H99 would be as effective in controlling northern leaf blight as using Ht resistance, or a combination of Ht resistance and moderate levels of partial resistance as found in Mo17.

Eight fungicides, ten botanicals and ten essential oils were taken for their in vitro evaluation against Exserohilum turcicum (Pass.) Leonard and Suggs incited of Northern Leaf Blight of Maize. Among all the tested fungicides (Azoxystrobin 23%, Thiophenate methyl 75%, Propiconazole 25%, Tebuconazole 25.9%, Captan 50%, Zineb 75%, Cymoxanil 8%+Mancozeb 64% and Zineb 68%+Hexaconazole 4%), propiconazole 25% showed maximum inhibition of mycelial growth (92.22%) under in vitro conditions at 5ppm concentration. Among all the tested botanicals Heena (Lawsonia inermis) was found to be most effective in inhibiting mycelial growth (71.11%) at 10% concentration. Lemon tulsi oil was found best in inhibiting mycelial growth (71.30%) of Exserohilum turcicum, among all the tested essential oils at 50ppm concentration. Fungicides, plant extracts and essential oils showing good results under in vitro conditions were tested under glasshouse conditions. Foliar spray of Propiconazole 25%[email protected]% showed reduced disease incidence (23.33%) compared to control (46.33%). Application of 5% of Heena extracts reduced the disease incidence (26.67%). Plants when sprayed with Lemon tulsi oil showed reduced disease incidence (24.17%). The study reveals that not only the fungicides but also the natural plant extracts can greatly contribute to reduce the incidence of disease because of the antifungal compounds present in plants.
