Weed management strategies for the control of Rottboellia cochinchinensis in maize in Trinidad
A weed management strategy for the control of Rottboellia cochinchinensis (Lour.) W.D. Clayton in maize, based on reducing the level of spikelet germination from the seedbank and reducing the intensity of weed‐crop interference, was conducted over two seasons.

| description | A weed management strategy for the control of Rottboellia cochinchinensis (Lour.) W.D. Clayton in maize, based on reducing the level of spikelet germination from the seedbank and reducing the intensity of weed‐crop interference, was conducted over two seasons. The management practices evaluated included chemical control (atrazine, metolachlor, pendimethalin, EPTC), cultural control (straw mulch), mechanical control (inter‐row cultivation) and biological control (living mulch). The results indicated that the various management practices had no effect on the growth and development of the crop but significantly affected the weed. The pendimethalin (1°5 kg a.i. ha−1) and inter‐row cultivation (14 and 28 days after planting) treatments gave satisfactory control of the weed in the crop over the duration of the critical period of weed competition. All other treatments were ineffective. All management practices made significant contributions to the weed seedbank, thus ensuring the predominance of the weed.

Zusammenfassung. Bekämpfung von Rottboellia cochinchinensis in Mais in Trinidad
Zur Bekämpfung von Rottboellia cochinchinensis (Lour.) W.D. Clayton durch Herabsetzung der Keimrate und der Konkurrenzstärke wurden über zwei Vegetationsperioden Versuche durchgeführt. Es wurden chemische Bekämpfungsmittel (Atrazin, Metolachlor, Pendimethalin, EPTC) eingesetzt sowie das Gras indirekt (Strohmulch), mechanisch (Jäten von Hand, Hacken zwischen den Reihen) und biologisch (Untersaat) bekämpft. Die verschiedenen Verfahren blieben ohne Wirkung auf die Entwicklung der Kulturpflanze, wirkten aber signifikant auf das Unkraut. Mit Pendimethalin (1,5 kg AS ha−1) und der Bodenbearbeitung zwischen den Reihen (14 und 29 Tage nach der Aussaat) ließ sich eine befriedigend Bekämpfung über die kritische Phase der Unkrautkonkurrenz hin erreichen. Alle anderen Maßnahmen waren unwirksam.
