Abstract:
In order to provide a scientific reference for the prevention of soybean root rot in hilly area of Sichuan Province,Carbendazim and Oxadixyl Anchor were used to control root rot in maize-soybean relay strip intercropping.The control effect,agronomic traits and yield were investigated.It was found that incidence rate decreased significantly with different medicaments,methods and control times.The incidence rate decreased from 78.7% to 38.7% and disease index decreased 0.106,respectively with seed dressing of Oxadixyl Anchor.The incidence rate increased and relative control effect decreased with the delay of control time.The nod number,plant height and stem diameter all increased with seed dressing and spraying at 3-leaf stage with Oxadixyl Anchor.The valid pod increased and invalid pod decreased with different medicament.The 100-seed weight increased significantly under all treatments,seed number and weight per plant increased significantly in B1 treatment,and A2B1 was the best treatment,increased by 32.08%,10.67% and 28.99% than CK respectively.With different control times,there was significant difference in 100-seed weight and no significant difference in seed weight per plant.The seed number per plant of B1 was significantly higher than that of B3.Seed dressing with Carbendazim and spraying at 3-leaf stage could significantly increase soybean yield by 20.07% and 11.65% respectively,and yield increased by 9.29%-23.82% with the treatment of Oxadixyl Anchor.
