Transgenik Olmayan Mısırda (Zea mays L.) Yabancı Ot Mücedesinde Yaygın Olarak Kullanılan Herbisitlerin Karşılaştırılması

Weeds cause significant economic losses in corn, also known as maize, yield. Herbicides are the most widely used tools for weed management. Weed control for genetically modified crops (GMOs) such as corn is generally based on the use of post-emergence glyphosate and 2.4-D herbicides. However, transgenic modified corn crop production is prohibited in the European Union and Turkey hence weeds in corn fields in these countries; pre-sowing, pre-emergence and post-emergence herbicides can be use in three different periods. In this study, the effect of commonly used herbicides on weed control in corn was investigated. The highest corn yields were obtained from dimethenamide-P 280 g / l + terbuthylazine 250 g / l (13.055 kg ha-1), mesotrione 75 g / l + nicosulfuron 30 g / l (12.979 kg ha-1) and terbuthylazine 270 g / l + pendimethalin 64 g / l (12.746 kg ha-1), respectively. The maximum harvest indexes were determined in dimethenamide-P 280 g / l + terbuthylazine 250 g / l (53%), mesotrione 75 g / l + nicosulfuron 30 g / l (52%) and terbuthylazine 270 g / l + pendimethalin 64 g / l (50%) applications. The weed indexes were detected in order of dimethenamide-P 280 g / l + terbuthylazine 250 g / l (7%), mesotrione 75 g / l + nicosulfuron 30 g / l (8%) and terbutylazine 270 g / l + pendimethalin 64 g / l (10%). When the results were evaluated as a whole, it was concluded that dimethenamide-P 280 g / l + terbuthylazine applications could be preferred to weed control in corn production areas, primarily. However, because of the environmental problems that can only be caused by chemical-related struggles in the long run, environmentally friendly applications such as alternation, mulching, solarization, steam disinfection, smart cultivators and sensor sprayers need to be integrated into herbicide applications for sustainable weed control in corn production.
