Hey Binghi,
The flying training is 40hrs comprised of both dual and solo. Some training places have dual controlled Ag planes, some use 180s and 185s for the dual and a single seat Ag plane for the solo.
From memory we started by doing alot of 500ft stalls in turns, then went through to flying overloaded aircraft, dumping, application techniques and use of the gps for tracking.
There is alot to learn and and alot to unlearn as it is quite different from nearly all other aspects of aviation.
