Effect of Crop Rotations on Rotylenchulus reniformis Population Structure

摘要: Leach, M., Agudelo, P., and Lawton-Rauh, A. 2012. Effect of crop rotations on Rotylenchulus reniformis population structure. Plant Dis. 96:24-29. is a highly variable nematode species an economically important pest in many cotton fields across the southeastern United States. Rotation with resistant or poor host crops method for management reniform nematode. We studied effect six planting schemes covering four 120-day cycles predominant genotype R. reniformis. Rotations used were: (i) to corn; (ii) susceptible soybean (iii) cotton; (iv) corn (v) continuous soybean; (vi) cotton. After each cycle, amplified fragment length polymorphisms (AFLPs) produced from primer pairs were determine rotation A total 279 polymorphic bands scored using combinations. Distinct changes composition observed following corn. involving (susceptible resistant) had greatest The characterization field variability responses plants can help extend durability varieties identify effective schemes.
