Simulateur de pulvérisation localisée d’herbicide

Abstract : Site-specific spraying is a technological lever to reduce the herbicide amount used in the case of chemical control of weeds. At the present time, detection and control technologies are available to apply herbicide only where weeds are present and thus provide an alternative to homogeneous application of chemicals on the entire surface of the field. In order to assess this practice, a digital simulator has been developed combining virtual infestation maps with different theoretical sprayer configurations. Simulations were used to localize herbicide applications and quantify herbicide reduction based on the spatial distribution of weeds and the width of independent spray units (boom sections or individual nozzles). Moreover, depending on the type of nozzle, the occurrence of under-application (with a risk of weed-control failure) is studied by taking into account the transverse distribution of the herbicide under the nozzle.
