**8. Conclusion**

Ozone has demonstrated be useful for management of postharvest of climacteric fruits such as mangoes and papayas. This ecotechnology is cost effective and is very promising to use in developing countries of Latin América. Using ozone watering in Nopal opuntia crops, proved to be very effective to control diseases and increase plant health. An adequate ozone irrigation system prevents growth of bacteria and bugs in citrus trees, and other fruits, and is an alternative to reduce HLB infestation. Sugarcane and other important crops growing in tropical areas increase yield using ozonated water, and an early diagnose of diseases reduce losses and increase the economic benefit in productive areas. TRIO3 acknowledges all the producers and scientific investigators involved in the protocols developed during these last 10 years.
