Effects of foliar glyphosate on young wild cherry (Prunus avium L.) seedlings in Düzce.

Wild cherry (Prunus avium L.) is an ecologically, economically, and socio-culturally prominent natural broadleaved tree species of Turkey. Glyphosate is a widespread chemical used to control weeds in the Turkish agriculture. In the present study, the short-term effects of the two different rates [%1 ve 2 (volume:volume)] of glyphosate sprayed on young wild cherry seedlings planted on a natural beech site in Akçakoca (DÜZCE) planted with 3 x 3 m spacing in June 2008 were evaluated. Herbisit solutions were applied in and around seedlings rows in a broadcast manner using a 20-L backpack sprayer so as to determine herbicide safety for the tree species. A mechanical weed-control treatment was added to the study for comparison. 10 months after treatments, although herbicide treatments effectively controlled weeds in seedling rows, significant herbicide damages occurred on seedlings. Acessive spraying partly might account for these results. In conclusion, herbicide use and crop safety in wild cherry should be further studied with future studies.
