The use of maize as replacement crop in trifluralin treated cotton fields in Turkey

Maize and cotton are primary crops in Turkey. Trifluralin is commonly used in cotton. In some years heavy rain after cotton sowing kills cotton seedlings. Although maize is the best choice as a replacement crop, the trifluralin label prohibits maize sowing for 12 months. The current study was carried out to look at possible use of maize as a catch crop in trifluralin treated cotton fields. Maize varieties showed varying response to trifluralin. However, better and worse responding varieties responded to trifluralin similarly in field conditions due to environmental conditions which was favorable for higher trifluralin loss. Temperature during flooding and duration of flooding do not have any affect on trifluralin injury.
