Pearl millet is the first cereal produced and consumed in Niger. However, its production hampered by several types of constraints including pearl millet downy mildew. The objective of this study is to assess the effect of variety + mineral fertilizer and variety + seed treatment combinations for the integrated management of pearl millet downy mildew. A Split-split-plot device with three factors (variety, mineral fertilizer and fungicide) is used. Data on the incidence and the severity of downy mildew are collected and analyzed. The incidence of the disease reached 8.13 ± 2.24% and 5.24 ± 1.69% after application of 2 g of DAP and 6 g of N15P15K15 per packet respectively compared with 12.41 ± 2.43% for the control. The application of N15P15K15 has more effect with ICRI-Tabi and that of DAP with ICMV-IS 89305. The severity of the disease went from 9.65% for the control at 5.27% after treatment of seeds with Apron Star42W.This effect is more remarkable at the level of HKP and ICRI-Tabi. The study has shown that the application of mineral fertilizer to seedlings reduces the infection of pearl millet downy mildew. In addition, N15P15K15 has more effect than DAP. Likewise, seed treatment with Apron Star42W significantly reduces the attack of the disease.

Abstract
Pearl millet is the first cereal produced and consumed in Niger. However, its production hampered by several types of constraints including pearl millet downy mildew. The objective of this study is to assess the effect of variety + mineral fertilizer and variety + seed treatment combinations for the integrated management of pearl millet downy mildew. A Split-split-plot device with three factors (variety, mineral fertilizer and fungicide) is used. Data on the incidence and the severity of downy mildew are collected and analyzed. The incidence of the disease reached 8.13 ± 2.24% and 5.24 ± 1.69% after application of 2 g of DAP and 6 g of N15P15K15 per packet respectively compared with 12.41 ± 2.43% for the control. The application of N15P15K15 has more effect with ICRI-Tabi and that of DAP with ICMV-IS 89305. The severity of the disease went from 9.65% for the control at 5.27% after treatment of seeds with Apron Star42W.This effect is more remarkable at the level of HKP and ICRI-Tabi. The study has shown that the application of mineral fertilizer to seedlings reduces the infection of pearl millet downy mildew. In addition, N15P15K15 has more effect than DAP. Likewise, seed treatment with Apron Star42W significantly reduces the attack of the disease.

Abstract: (french)
Le mil occupe la première place des céréales produites et consommées au Niger. Cependant, sa production est entravée par plusieurs types de contraintes dont le mildiou du mil figure au premier plan. L’objectif de cette étude est d’évaluer l’effet des combinaisons variété + fumure minérale et variété + traitement de semences pour la gestion intégrée du mildiou du mil. Un dispositif Split-split-plot avec trois facteurs (variété, fumure minérale et fongicide) a été utilisé. Les données sur l’incidence et la sévérité du mildiou sont collectées et analysées. L’incidence de la maladie atteint 8,13±2,24% et 5,24±1,69% après application respectivement de 2 g de DAP et de 6 g par poquet de N15P15K15 contre 12,41±2,43% pour le témoin. L’application de N15P15K15 a plus d’effet avec ICRI-Tabi et celle de DAP avec ICMV-IS 89305. La sévérité du mildiou passe de 9,65% pour le témoin à 5,27% après traitement de semences avec Apron Star42W. Cet effet est plus remarquable au niveau des variétés HKP et ICRI-Tabi. L’étude a montré que l’application de la fumure minérale au semis permet de réduire l’infection du mildiou du mil. Par ailleurs, le N15P15K15 a plus d’effet que le DAP. De même, le traitement de semence avec Apron Star42W réduit significativement l’attaque de la maladie.
