Portée Et Impact De La Dérivé Sur Les Arthroodes Des Principaux Produits Phytosanitaires Utilises Des Cultures Maraichères Des Niayes Du Sénégal

Abstract:In the northern fringe of the Louga region, when plant protection products are sprayed, a relatively large proportion may be lost to the environment. This could have harmful consequences for the health of operators and biodiversity. The aim is to assess and measure the range of droplets from plant protection product drift treatments in relation to climatic conditions, as well as their impact on health and arthropods. The study is being conducted through a survey of 122 market gardeners and on-farm experimentation.As a result, 81% of the growers surveyed had very clear ideas about the problems associated with spray drift. 67% of growers estimated that 10% of the spray liquid used during spraying ended up in the untreated zone. The study also showed that the potential drift distance applied to the tomato crop with the use of a manual backpack sprayer is 6.875 m. The differences between the arthropods found before and after treatment ranged from 1 to 27 individuals per 0.5 m collection point within the first five metres of drift.In conclusion, knowledge of drift and its extent is very important information in the prevention or reduction the negative impact of the use of plant protection products
