Abstract

In order to compare effect of magnetic field and frigate surfactant to enhance the efficacy of Iodosulfuron-methyl-sodium plus Mesosulfuron-methyl (chevalier) to control wild oat, a greenhouse experiment of dose-response was conducted. Treatments were 0, 3, 6, 12, 18 and 24 doses g a.i. ha-1 of chevalier (i) without treatment, (ii) with Frigate % 0.1 v/v, (iii) with magnetic field, and (iv) Frigate % 0.1 v/v plus magnetic field with four replications. Besides, the effect of treatments on surface tension was evaluated. Magnetic field and Frigate reduced the surface tension of water and chevalier spray solution significantly. But Frigate as compared to the magnetic field was more effective in reducing surface tension of water and chevalier spray solution. Furthermore, magnetic field and Frigate increased the efficacy of chevalier remarkably. Applying magnetic field when chevalier mixed with Frigate showed more efficacy than applying the magnetic field and/or Frigate alone.
