The only thing you could try would be suing for interference with your contractual relations in leasing the land, but legally it is not unlawful for him to make deals to have his brother rent to people who buy insurance from him. This is borderline in that the insurance agent cannot pay the landowners any kickbacks for getting his tenants to buy insurance from him and the insurance agent cannot be splitting commissions with a non-agent, but you would need proof of this or file a complaint with the insurance commissioner for investigation into whether or not he is splitting fees or giving kickbacks which could be illegal depending on exactly what he is doing with the fees or money.
