Chemical devitalization of stumps of hazel-trees and ash-trees

1990
Cet essai vise à tester 11 traitements destinés à dévitaliser des souches de noisetier et de frêne. Deux facteurs sont étudiés : le mode d'application (pulvérisation après la coupe, dépôt en même temps que la coupe, badigeonnage), la matière active (glyphosate ; triclopyr ; 2,4-D + 2,4-DP ; 2,4 - D + triclopyr ; sulfamate d'ammonium).
