Statement from pilot - I went out to practice spraying a field with water in nxxxxx. I did two laps around the field, then came around to purge the booms across the middle of the field. I pushed the spray lever forward when my knuckles hit the dump lever and the gate popped open. I shut the gate, resumed purging the booms and came up out of the field stalling the airplane. At the time, I didn’t recognize it as a stall and thought the gate had come open again and it was making the airplane porpoise. I tried pulling the dump lever to get it to stop and then added full power. I continued to sink and fight the stall. I was getting extremely low and decided my only option was getting the airplane on the ground. I impacted the ground very hard tearing the landing gear off aloong with various other parts. I was able to keep the airplane straight until it caught something on the ground and whipped the airplane around 180 degrees where it came to a stop.
