Relationship of contact angle of spray solution on leaf surfaces with weed control

Abstract The weeds are important in agricultural and livestock areas because these plants can cause several damages, especially in the yield. The herbicide pulverization for weed control is the most used, but the efficiency of the control can be dependent the several factors, for example, the correc...
