ORIENTATIVE RESEARCH ON CONTROL OF PERENNIAL<br />

WEEDS IN POTATO FIELDS<br />

Summary<br />

Results obtained in experiments carried on in 2 localities showed same procedures<br />

in controlling the perennial weeds by mechanical hoeing and herbici<strong>de</strong>s.<br />

The repeated.) ploughings were combined with the disk-ha:rrows work, but the<br />

weeds were not significantly controlled. The herbici<strong>de</strong>s aminotriazol (15 kg/ha)<br />

and glyphosate (2.5-3.5 kg/ha) appIied in September when the weeds were<br />

20-40 em high. have reduced theamount of the weeds with 40-900/0" Even the<br />

weeds like Cirsium arvense, Convolvulus' arvensis, Mentha sp. .and Agropyrum<br />

repens were better eontl'olled in such a way. A poor effeet was enregistered for<br />

Symphytum officinale and Equisetum arvense.<br />

FORSCHUNGSERGEBNISSE ZUR BEKĂMPFUNIG<br />

DER M!EHRJÂHRIGEN UNKRÂUTER IM KART·OFFELANiBAU<br />

Zusammenfassnng<br />

Die Versuehsergebnisse zur Bekămpfung einiger perennieren<strong>de</strong>n Unkrauter,<br />

durch mechanische Massnahmen und Unkrautmittel, wer<strong>de</strong>n bekanntgemacht. Die<br />

Vel'suche wur:<strong>de</strong>n an zwei Standorten durchgefiihrt. Die wie<strong>de</strong>rholte Bo<strong>de</strong>nbearbeitung<br />

allein, hat die Unkrautmasse nicht signifikant reduziert.<br />

Die Unkrautmittel Aminotriazol (15 Kg/Ha) und Glyphosate (2,5-3,5 KgjHa),<br />

angewen<strong>de</strong>t in September, bei 20-40 em. Unkrauthohe, haben die Unkrautmasse<br />

mit 40-90% reduziert.<br />

Gut bekămpft waren die Unkrăuter Cirsium arvense, Convolvulus arvensis,<br />

Mentha spp., und Agropyrum repens und nul' schwach die Unkrauter Symphytum<br />

officinale und Equisetum arvense.<br />
