Dry grape is one <strong>of</strong> the most important <strong>and</strong> widely produced <strong>and</strong> exported product in Turkey.<br />
(Anonymous 2009).<br />
This study was carried out in organic vineyards <strong>of</strong> Alaşehir - Manisa province with the<br />
objective <strong>of</strong> determining the presence <strong>of</strong> the weeds, <strong>and</strong> investigate the possibilities <strong>of</strong> using<br />
physical control method in their control.<br />
For the above mentioned purpose survey <strong>and</strong> field experiments were conducted in organic<br />
round seedless (Sultana variety) vineyard. Field experiment, included 12 characters namely, control,<br />
black polyethylene mulch, olive waste, h<strong>and</strong>-hoeing,mechanical-hoeing, flame burning, cerealstraw<br />
(covered at least 10 cm), peanut waste, wood waste, cover crop (5kg/da Barley(Akhisar<br />
variety) + 6 kg/da wetch (Menemen 79 variety), cover crop ( 8 kg/da Hairy wetch (Efes79 variety),<br />
<strong>and</strong> 500 kg/da cabage waste. <strong>Weed</strong> presence was evaluated both inter-row <strong>and</strong> in-row.<br />
.Survey results,showed that in organic vineyard the most abundant weed spesies were,<br />
Matricaria chamomilla L. (74%,), Phragmites communis L. (71%), Poa annua L. (70%), Cynodon<br />
dactylon (L.) Pers. (67%), Sonchus oleraceus L. (63%), Stellaria media L.( 61%) Convolvulus<br />
arvensis L. (60%), Lactuca serriola L.( 58%), Cynanchum acutum L. (53%) Cyperus roduntus L.(<br />
48%), Setaria verticillata L. (40%).<br />
Field experiments showed that in inter-row, black polyethylene mulch provided almost total<br />
control <strong>of</strong> Avena fatua L.,(%100 ) Medicago polymorpha L., (% 100) Papaver rhoeas L., (%100)<br />
Lactuca serriola L., (100) Sisymbrium <strong>of</strong>ficinale (L.)., (%100) Hordeum murinum L., (%100)<br />
Cynanchum acutum L., (%100) Matricaria chamomilla L., (%98,0) Sonchus oleraceus L. Good<br />
control was also provided with wood waste, cereal straw, peanut shell,followed by cover crops.<br />
A similar result was taken as the in-row, black polyethylene mulch provided almost total<br />
control <strong>of</strong> Cynanchum acutum L. (100%), Dacus carota L. (100%), Hordeum murinum L.(100%),<br />
Lactuca serriola L.(100%), Matricaria chamomilla L.(100%), Medicago polymorpha L. (100%),<br />
Malva neglecta L. (100%), Poa annua L.(100%), Phalaris minor L. (100%), Sisymbrium <strong>of</strong>ficinale<br />
(L.) (100%), Sonchus oleraceus L. (100%), Stellaria media (L.) Vill. (100%), Amaranthus<br />
retr<strong>of</strong>lexus L. (100%), Cynodon dactylon L. (100%), Cyperus rotundus L. (100%), Xanthium<br />
strumarium L. (100%). Good control was also provided with cereal straw, wood waste, peanut shell<br />
followed by cover crops.<br />
İn conclution, in inter row black polyethylene mulch, wood waste, cereal straw, peanut shell<br />
<strong>and</strong> cover crop are promising for physical weed control. Is in-row <strong>of</strong> organic vineyard, mulch<br />
cover, cereal straw, wood waste, peanut shells <strong>and</strong> cover crops for weed control are promising.<br />
