Essai de caractérisation des opérations de lutte chimique contre les saute-riaux au nord du Burkina Faso (1990-1992)

Abstract

Characterisation of Grasshopper Chemical Control in Northern Burkina Faso (1990-1992). Description forms of 393 Chemical grasshoppers control operations between 1990 and 1992 in the north of Burkina Faso are analysed. It is shown that the campaign could be divided in two parts. During the first one (mainly July), farmers carry out numerous treatments on small plots in cultivated areas to protect recently planted crops (pearl millet and sorghum). Sprayers installed on trucks are used during the second part of the campaign, mainly in October, in cultivated and fallow areas to protect crops at the critical period of grain maturation.
