“…Five treatments used were as follows: parkia fruit powder, parkia fruit peel powder, neem leaf powder, neem seed powder and a control (only sorghum infested with Striga with no plant material). Further, after pre-irrigation, sorghum seed (cultivar CMDT 45, highly susceptible to Striga) (Marley et al, 2004) was sown and thinned to one plant/hole, four plants/pot. Fifteen days after sowing (DAS), compound fertilizer 15 : 15 : 15 (N : P : K) and urea were applied 21 and 42 DAS, respectively at the recommended rate of 64 kg N ha 7 1 .…”

“…Management approaches for control of Striga in Nigeria are generally based on cultural control strategies such as trap cropping, appropriate rates of fertilizer and suitable herbicide application, hand pulling and hoe weeding (Kuchinda et al, 2003) and host plant resistance (Lagoke et al, 2000;Marley et al, 2004) where available.

Striga hermonthica is a major threat to cereal production in Nigeria. Management approaches for control of Striga are generally based on cultural control strategies and host plant resistance. The use of plant products for the control of S. hermonthica is limited. Seed and leaf powders of neem and fruit and fruit peel powders of parkia trees were evaluated under screenhouse and field conditions in the Nigerian Savanna. Screenhouse evaluation of the plant materials showed that neem seed powder was the most effective, with only 16.5% of Striga emergence. This was followed by parkia fruit powder and parkia fruit peel powder, with 29.1% and 38.8% Striga emergence respectively. In the field, all plant materials significantly reduced Striga emergence. The lowest number of emerged Striga plants was observed on plots treated with neem seed powder (with 1.7 emerged Striga per 3m 2 while the control plots had 30.3 emerged Striga plants per 3m 2 ). Crop plants treated with neem seed powder did not show any reaction to Striga infestation, while parkia fruit powder and parkia fruit peel powder had reaction scores of 1.7 and 2.0 respectively when compared to neem leaf powder with 3.0 and the control with 4.7. Treatment by all the plant products however, significantly increased grain yield, which was highest in the treatment with neem seed powder. Our results highlight the possibilities of using these plant products for the control of S. hermonthica.

The ability of Fusarium oxysporum (PSM 197), a potential mycoherbicide for control of Striga hermonthica, to control different Striga species (S. hermonthica, S. asiatica and S. gesneroides) and another parasitic weed, Alectra vogelli, was investigated under glasshouse conditions. Significant reductions in the total number of emerged plants of S. asiatica (91.3%), S. gesneroides (81.8%) and S. hermonthica (94.3%) were achieved in the presence of F. oxysporum (PSM 197). The pathogen only caused a reduction of 8.5% in A. vogelli. This high susceptibility of the three Striga species provides a possible opportunity to control these parasites simultaneously with this mycoherbicide.

“…It is the dominant parasitic weed species in the Nigerian Savanna, occurring in ecological zones extending from latitudes 7-14 N 0 . It is one of the major threats to cereal production where severe damage can cause total crop loss in farmers' fields particularly under low fertility conditions (Lagoke et al, 1991;Ogungbile et al, 1998;Kim el al., 2002, Marley et al, 2004.…”

The experiments were conducted in the Pathology Laboratory of the University of Agriculture, Makurdi (07 0 E14'N, 08 0 38'E) with the principal objective to evaluate sesame and Pigeon pea genotypes in their ability to stimulate germination of S. hermonthica seeds. The treatments consist of 17 and 13 varieties of Sesame and Pigeon pea, respectively. These varieties were screened in a completely randomized design (CRD) with four replications. There were significant differences among the varieties of Sesame and Pigeon pea in respect to relative germination percentage. In sesame, higher relative germination of 47.8% and 30.4% were recorded with variety 69B-882 and Yandev 55, respectively. The relative germination of 16-28% was recorded by varieties: -Ex-Pankshin -98, 73A-79B, Cross-95, E-8, Ncriben -01M, 73A-892B, 60-2-3-1-8B, and Ciano-16. The 17 sesame varieties were grouped in four (4) based on their efficacy to stimulate seed germination of S. hermonthica: High (69B-882 and Yandev 55), Moderate (ExPankshin -98, 73B, Cross-95, E-8, Ncriben-01M, 73A-82B, 60-2-3-1-8B and Ciano-16); low (Yandev-75, Type-4, Ciano -27, Eva and 69-1-1); Very low (Pachequeno, Ncriben-03L), respectively. But in the Pigeon pea accessions, the percentage germination of Striga seeds was highest with TCC 1035, Cita 4, TCC 6, TCC 8126, Cita 3, TCC 87 and Cita 2 (in descending order, 4.03 to 3.05%). These were followed by TCC2, TCC 8129, TCC 151 and Cita1 (2.99 to 2.06%) and the TCC8 and TCC 8129 (1.74 and 0.76%). The two test crops (sesame and Pigeon pea), the two controls, (GR -24 and water) recorded the highest and lowest germination percentages, respectively. In the two varieties, the high and moderate stimulant producers can be used as good trap varieties. There is the need to screen more sesame and Pigeon pea genotypes to increase the potential for use of this control strategy.
