Organik tarımda yabancı ot kontrolü için organik herbisitlerin kullanımı gün geçtikçe artmaktadır. Bu çalışmada seçici olmayan
organik herbisitlerden BioLink (%4, %6 ve %9), Matran® EC %15 ve WeedZap %15 konsantrasyonlarına adjuvan olarak BioLink
%1, farklı su miktarları (30 gal/A*=28,06 l/da ve 60 gal/A=56,12 l/da) ile uygulamalarının arazi koşullarında yazlık yabancı ot
türlerinden geniş yapraklı Amaranthus retroflexus L. (horoz ibiği) ve Portulaca oleracea L. (semiz otu) ile dar yapraklı Cyperus
rotundus L. (topalak)’un kontrolündeki etkinliği araştırılmıştır. Sonuç olarak bu çalışmada kullanılan geniş yapraklı yabancı ot
türlerinin kontrolü dar yapraklı yabancı ot kontrolüne göre daha kolay olduğu saptanmıştır. İlaçların etkinlik değerleri herbisitlerin
uygulama gününden sonra gün sayısı arttıkça azalmıştır. Ayrıca kullanılan yüksek su miktarı ilaçların etkinliği arttırmıştır. Her üç
yabancı ot türü için BioLink %9 + BioLink %1 adjuvan uygulaması (56,12 l/da) 15.gün sayımında A. retroflexus için %98,75, P.
oleracea için %92,00 ve C. rotundus için %40,00 etkili bulunmuş ve istatistiksel olarak diğer uygulamalardan farklı saptanmıştır.

Effect of Organic Herbicides Applied by Different Water Volume on Weed Control

Öz

The use of organic herbicides for controlling weeds in organic agriculture is increasing day by day. In this study, non-selective
organic herbicides BioLink (4%, 6% and 9%), Matran® EC 15% and WeedZap 15% by adjuvant BioLink 1% with using different
amounts of water (30 gal/A*=28.06 l/da and 60 gal/A=56.12 l/da) were investigated for the control of broadleaf weeds Amaranthus
retroflexus L. (redroot pigweed), Portulaca oleracea L. (Common purslane) and narrowleaf Cyperus rotundus L. (Purple nutsedge)
from summer weed species in field conditions . As a result, control of broadleaf weed species was found to be easier than
narrowleaf weed control in this research. The efficacy values of herbicides decreased as the number of days increased after the
application day of the herbicides. In addition, the amount of high volume water used increased the effectiveness of the herbicides.
BioLink% 9 + BioLink%1 adjuvant application (56.12 l/da) for all three weed species was effective at 98.75% for A. retroflexus,
92.00% for P. oleracea and 40.00% for C. rotundus at 15th day count and statistically different from other applications.
* 1 gal/acre : 0.93540 l/da.
