Chemical Control of Sasaella ramosa Makino in Mulberry Fields

Abstract

Sasaella ramosa Makino has raised serious ploblems for the productivity and the managements of mulberry in Fukushima Prefecture. In field experiments, Glyphosate [N-(phosphono-methyl) glycine isopropylamine, emulsifiable concentrate, active ingredient 41%], a translocated type herbicide, was tested for the control of S. ramosa Makino by foliage application in mulberry fields.
Glyphosate (spray volume: 400l/ha of 20 or 40 times dilution) was effective for the control of S. ramosa Makino including the subterranean stems in the application at mid-summer or early winter.
Glyphosate applied between mulberry rows did not injure mulberry, without so much as the spray solution drifted on the foliage of mulberry.
