Spot spraying in oilseeds and protein crops

Abstract

Prod 2019-3b pole BAP Pole EA SPE GESTAD AGROSUP; International audience; Currently, spraying chemical products in agriculture became the main means of weed controlbecause this cultural practice is very fast, inexpensive and very effective. However, awarenessof their negative impacts (environment, human health) requires thinking about new technicaland agronomic solutions. New technologies are promising techniques for a site-specific weedmanagement through the development of localized spraying.Some sprayers (often small width) located on the row may be able to answer thoseexpectations but they are most often expensive. In this context, the objective of the project“PLEVOP” (development of spot sprayer in oilseed and protein crops), proposed byTerres-Inovia, is the operational development in arable crops of a spot sprayer located on therow through model crops: the rapeseed and sunflower. The aim is to complete the chemicalweeding on the row by mechanical weeding (hoeing) on inter-row. Working with amanufacturer, MARECHAL, the objectives of the project are to 1) explore the potential of thissystem, 2) define its use conditions (volume, nozzle type, nozzle height, speed of passage, highwork output ...) and the effectiveness of this technique, in order to provide quality advice tofarmers.Through the tests conducted we want to 1 / know the influence of the type of guidance (GPSRTK,tracer wheels, vision ...) on this type of spray and 2 / study the biological efficiency onweeds by comparing it to that full treatment.Finally, to qualify the environmental gain (reduction of use and impact) and to evaluate thepracticability and the economic balance will be undeniable assets to accompany the farmer innew agri-environmental practices.
