Narrative:

As a pilot I landed the airplane at ZZZ and experienced a potential head on collision with an agriculture airplane. Luckily I saw the other plane. The root cause of this event is the 2 way radio communications. Based on discussions with the ground crew; portable hand-held radios were also not used in the spray planes. Events: aircraft X approached the airport from the west. The windsock was observed at 3;000 feet MSA altitude with wind blowing east to west; therefore it was decided that the landing would be against the wind on runway xx. The pilot announced on CTAF that aircraft X would be landing on runway xx. This pilot also announced that aircraft X would enter a 45 degree approach to the downwind left traffic runway xx. Before turning to left base; I announced the turn and again announced base to final to runway xx. On final approach the incoming airplane was a yellow spray plane taking off 'downwind' and observed in the windscreen of aircraft X. The spray plane veered to his right and did not communicate at any time. After landing; pilot inquired with the spray plane ground crew as to whether their yellow spray planes have radio communication; or whether those pilots also carry portable radios; and the answer was no! At a minimum for safety and liability reasons; all aircraft entering and leaving ZZZ should have 2 way radio communications to minimize the possibility of a mid-air collision. It is inherently dangerous to operate an aircraft so carelessly in the following ways:1) to take off downwind which is against other incoming air traffic.2) to takeoff with no announcement; including no communications with other incoming or outgoing air traffic. Conclusion: [spray plane] company should not be allowed to operate at ZZZ without maintaining 2 way radio communications. To do otherwise greatly increases the risk of midair collision and opens up ZZZ and their operators to serious questions of liability. These spray plane takeoffs occur several per day during spray season. Your attention to this matter would be appreciated.
