Abstract
Field dodder (Cuscuta campestris yuncker) is an important parasitic weed that has negative impacts on the growth and yield of alfalfa (Medicago sativa L.). Effective control of field dodder in alfalfa crops is necessary to reduce yield losses. Field studies were conducted to evaluate the efficacy of various herbicides on field dodder in a new-seeded alfalfa crop at three locations (Karaj, Jiroft, and Urmia) in Iran during 2020–2021. The herbicides evaluated were imazethapyr (100 g a.i. ha−1), glyphosate (six doses ranging from 143 to 348 g a.i. ha−1 + ammonium sulfate at 8 kg ha−1), and propyzamide (1250, 1500, and 1750 g a.i. ha−1). The results demonstrated that propyzamide at 1750 g a.i. ha−1 provided complete control of field dodder in terms of percentage change in biomass at first (100%) and second (99%) cuttings of alfalfa in Urmia. The imazethapyr at 100 g a.i. ha−1 provided 96 and 87% control at the first and second cuttings, respectively, whereas propyzamide at 1750 g a.i. ha−1 showed the best efficacy in increasing alfalfa biomass at the first (up to 82%) and the second cuttings (up to 81%), depending on the location. Glyphosate provided reasonable control of the field dodder at the first (73%) and the second cutting (82%). However, at higher rates (307 and 348 g a.i. ha−1), it caused significant reductions in alfalfa biomass due to crop injury, especially at the first cutting. The use of propyzamide at 1750 g a.i. ha−1 is recommended for highly effective control of field dodder in alfalfa crops without compromising the crop yield.
