    A SURVEY ON WEED MANAGEMENT IN DRY LENTIL FIELDS
    (Corvinus Univ Budapest, 2019) Pala, F.
    A questionnaire consisting of 20 questions about weed, herbicide, tillage and crop rotation was applied to 100 lentil farmers to determine the current state of a weed problem in lentil fields in 2016. Common weeds were determined charlock mustard (Sinapis arvensis L., 36%), devil-on-all-sides (Ranunculus arvensis L., 16%), cleavers (Galium aparine L., 11%), makhobeli (Cephalaria syriaca L., 8%), and knapweed (Centaurea depressa L., 8%), respectively. The majority of participants used aclonifen (89%) as a post-emergence to control broadleaf, besides, clethodim (26%), haloxyfop-methylester (17%), tepraloxydim (16%), quizalofop p-ethyl (15%), and fluazifop p-butyl (6%) for grass, respectively, and as a total herbicide glyphosate (4%) as well. But, respondents (66%) stated that lentils had crop injury from aclonifen. Growers took into account the price (43%), herbicides (38%), weeds (10%) and crop rotation (9%) to choose herbicides. Managing weeds with hand-picked (76%) were common in areas that did not use herbicides. Preventive measures were used such as crop rotation (61%), late sowing (10%), and deep tillage (4%), furthermore, farmers planted wheat (91%) and barley (9%) as a preceding crop. In this study, dissatisfaction was determined by the efficacy and selectivity of aclonifen which is registered herbicide on lentils in Turkey. Lentils have a short stature, slow early-season growth rate, and open-canopy growth habit, which make them poor competitors with broadleaf weeds. So weed management in the early period such as pre-planting, pre-emergence or early post-emergence herbicides, and IMI herbicide-tolerant lentil varieties (Clearfield) have been investigated.
