Abstract
Rice farming in the Cote dIvoire faces enormous constraints, including that of adventitious management. A study on rice adventitious was conducted with the objective of inventorying rice adventitious as well as herbicides that are used for chemical control in the city of Daloa. Thus, 60 rice growers selected at random and from three (3) bunds representing plots of approximately four (4) meters were randomly selected. In each plot, all the weeds met were identified as well as the herbicides used by the rice growers. Floristic surveys have identified 34 species divided between 30 genera and 15 families. The most represented families are the Poaceae, Cyperaceae, Asteraceae, Euphorbiaceaes and Amaranthaceae. A total of 14 herbicides have been identified and their choice by the rice grower is essentially guided by the experience of rice growers on their effectiveness. We have counted as for the herbicides used, 2,4-D amine salt and glyphosate because of their large spectrum of action on weeds.
