Banded herbicide applications with hooded field sprayers (HFS) provide safer applications in many crops. The aim of this paper is to show the effectiveness and safeness of selective and nonselective herbicide applications in a conventional sunflower production system (CSPS) using a combined hooded field sprayer (CHFS). | Turkish Journal of Agriculture and Forestry Turk J Agric For (2018) 42: 354-363 © TÜBİTAK doi: Research Article Banded herbicide application in a conventional sunflower production system 1, 1 2 3 Ahmet Tansel SERİM * , Ünal ASAV , Süleyman Gürdal TÜRKSEVEN , Ergin DURSUN 1 Plant Protection Central Research Institute, Ankara, Turkey 2 Department of Plant Protection, Faculty of Agriculture, Ege University, İzmir, Turkey 3 Department of Agricultural Machinery and Technologies Engineering, Faculty of Agriculture, Ankara University, Ankara, Turkey Received: Accepted/Published Online: Final Version: Abstract: Banded herbicide applications with hooded field sprayers (HFS) provide safer applications in many crops. The aim of this paper is to show the effectiveness and safeness of selective and nonselective herbicide applications in a conventional sunflower production system (CSPS) using a combined hooded field sprayer (CHFS). Glyphosate interrow and aclonifen or quizalofop-P-ethyl intrarow were applied in fields cropped with nonglyphosate-resistant sunflower varieties in Ankara, Tekirdağ, and Tokat Provinces of Turkey in 2015 and 2016. In Ankara and Tekirdağ, glyphosate caused limited injury to sunflower at 28 days after treatment (DAT), and aclonifen created transient phytotoxicity in 2015. Glyphosate was applied with aclonifen at + and + kg ai ha−1 or quizalofop-P-ethyl + and + kg ai ha−1 using band application units of CHFS together. Aclonifen and quizalofop-P-ethyl were also used at and kg ai ha−1, respectively, using the conventional application unit of CHFS. Glyphosate + aclonifen ( + and + kg ai ha−1) provided higher weed control and sunflower seed yield compared with the other treatments. Aclonifen ( kg ai ha−1) controlled many competitive arable weeds and increased sunflower seed .
