Narrative:

I was on a training mission with a student. I was directly over head of L19 and made a radio call on CTAF; 'wasco traffic call sign xxx directly over head at 4;000 ft doing a simulated engine failure to low approach to runway 30 wasco.' looking for traffic I noticed an agricultural plane clearing runway 12 and taxied to the run up of 30. I made another call; 'wasco traffic left downwind simulated engine failure to runway 30 wasco traffic.' turning base to final I made another call; 'wasco traffic final 30 simulated engine failure wasco.' at 300 ft the yellow agricultural plane took the runway and began his takeoff roll; at that point I took control of the plane and executed a go around off setting to the left of the runway. The agricultural plane made no radio calls and climbed to approximately 200 ft AGL. At the departure end of the runway he did a 180 degree turn and over flew the runway and departed south.

Title: BE36 Instructor pilot experiences a NMAC at L19 during a simulated engine out approach to Runway 12 using standard traffic calls. An agricultural aircraft that had landed Runway 12 and taxied clear began its' takeoff from Runway 30 with the BE36 on short final necessitating a go around.
