An agricultural airplane was damaged during a forced landing attempt following a loss of climb performance. The pilot reported loading the hopper with chemicals and departing from runway 30. During the climbout, at approximately 50 feet above ground level (AGL), the pilot noted a tailwind from the southwest. At 60 feet AGL, the climb rate diminished. The pilot then initiated a forced landing in a wash across a main road.
