Öz

Bu caltsmada, allelokimyasallardan juglon, katekol ve dopa'nin herbisit

o/arak etkileri sentetik herbisit o/an 2,4 -D ile karstlastirtlmtsttr.

Kutahya'daki ekin tarlalannda en yaygin yabanci otlann; Sinapis arvensis,

Cirsium arvense, Papaver rhoeas ve Lamium amplexicaule turleri oldugu

belirlenmistir. Allelokimyasallarin etkisi bu turler uzerinde arasttrtlmtsttr.

Aynca bugdayda allelokimyasallarin herbisit etkileri, sentetik herbisitlerden

2,4 - D 'nin etkisi i/e karsilastinlmtsttr. Allelokimyasallardan katekol ve

juglon 'un yabanci otlartn gelisimini ve klorofil icerigini onemli derecede

azaltugi fakat bugdayda cok olumsuz bir etkisinin olmadigt bulunmustur.

Sonuc olarak jug/on ve katekol allelokimyasallannin herbisit potansiyele

sahip olduklari ve doga! herbisit o/arak kullanilabilecekleri belirlenmistir.
