Management of the Striga epidemics in pearl millet production: a review
Abstract Pearl millet (Pennisetum glaucum [L.] R. Br.) is a drought-resilient and nutritious staple food crop widely cultivated in arid and semi-arid regions. Worldwide, pearl millet is ranked the 6th most widely produced cereal crop after wheat, rice, maize, barley, and sorghum, with a total produc...

| description | Abstract Pearl millet (Pennisetum glaucum [L.] R. Br.) is a drought-resilient and nutritious staple food crop widely cultivated in arid and semi-arid regions. Worldwide, pearl millet is ranked the 6th most widely produced cereal crop after wheat, rice, maize, barley, and sorghum, with a total production of 30.5 million tons on 32.1 million hectares. In Burkina Faso, it is the 3rd widely cultivated crop next to sorghum and maize, with a mean yield of 0.8 ton ha−1, far below the potential yield of 3.0 tons ha−1 attributable to various production challenges. Among the production constraints, the parasitic weed Striga species, particularly S. hermonthica is endemic and causes up to 80% yield losses under heavy infestation. Different control methods (e.g., cultural practices, chemicals and bio-herbicides) have been recommended, but they have been largely ineffective due to diverse and complex problems, including the life cycle, seed production, and prolonged seed dormancy of S. hermonthica; poor access and cost of implementation. Breeding for host plant resistance presents a cost-effective, environmentally friendly and affordable method for smallholder farmers to control and reduce Striga infestations and improve pearl millet yields. Therefore, the objectives of this study were to present the impact of S. hermonthica damage on pearl millet production and productivity and assess the effectiveness of different management methods of S. hermonthica with an emphasis on host plant resistance. The first section of the review assesses the impact of Striga infestation on pearl millet production, followed by the developmental stages of Striga, Striga infestation and damage management strategies, breeding for Striga resistance and other Striga control methods. The paper summarises genetic resources, new breeding technologies, and innovations for the precision and speed breeding of Striga-resistant cultivars. The review will guide the use of the best breeding strategies and accelerate the breeding of new pearl millet cultivars that are best-performing and resistant to S. hermonthica to reduce damage incurred by Striga infestations on farmers’ fields in Burkina Faso and related agro-ecologies. |
