Abstract:

The survey was conducted by 80 producers in 2016 in order to assess the problems faced in the struggle of foreign herbs in the cotton fields in Diyarbakır. In the survey, 16 questions were asked about foreign herbs and herbs. The study found that foreign herbs with problems from the point of view of cotton producers are 51 % pig (Xanthium strumarium L.), 22 % it grapes (Solanum nigrum L.), 8 % light grapes (Physalis spp.5 % horosibic (Amaranthus retroflexus L.) and 5 % chiaş [Sorghum halepense (L.) Pers.] It is identified. 41% of the survey participants that they used total herbicide (100% glyphosate) before the release. For large leaves, 94% were determined to use pre-October (55% pendimethaline, 33% fluometurone, 5% benfluraline, 2% trifluraline, 1% metholachlor-S+benoxacor) and 6% use pre-exit fluometurone. For narrow leaves, 88% have been found to use herbicide after exit. In the choice of herbicide, 53% said the price, 17% said foreign herbs, 16% said the rain and irrigation methods, and 12% said the vegetable product was effective. As a mechanical fight, 73% have two, 24% three and 3% have a hand + tractor diameter once. Since the rizomic and narrow leaves such as canyon and separation cannot be controlled by the diameter, the diameter is made for large leaves. According to the survey, 58% of participants said that the main plant of cotton was cotton, 30% corn and 12% grain. As a result, it has been important to develop foreign herb control methods in cotton and to develop alternative methods of control before and after departure to applications related to the use of herbicides before October.
