Plant health rallies in Intibucá, Honduras

Plant health rallies in Intibucá, Honduras

Plant health rallies in Intibucá, Honduras: Effect on knowledge and control practices of paratrioza in potato (PDF - Spanish)

Since its introduction in Honduras in 2002, Paratrioza, a devastating potato pest has been gaining strength especially in the Department of Intibucá, the country's most important region for potato production.

Since 2014, the National Service of Food Safety and Health (SENASA), in collaboration with CABI's Plantwise program, has implemented several plant health rallies in Intibucá to disseminate information on Paratrioza management among potato farmers. In April 2017 a small case study was conducted to find out the effect of extension activities on knowledge and practices used by farmers.

Full case study in Spanish language only.

  • Farmers who participated in plant health rallies have improved their knowledge of the pest and control practices.

  • Although monitoring is promoted at the plant health rallies as a decision-making tool, since it helps defining the need to implement control measures, most farmers prefer to make scheduled pesticide applications. Despite most farmers having heard of yellow sticky traps, none use them.

  • Farmers who participated in plant health rallies tended to use less toxic insecticides (class III and IV) than non-participants.

  • Farmers in the region receive visits from multiple organisations who  provide technical assistance. There were issues highlighted around confusion caused by different messages on the same issue.

  • The large distances between towns and the low population density make it difficult to reach large numbers of farmers with key messages with the plant health rallies. This makes it difficult to follow up and verify the impact they have made.

  • It is necessary to seek more coordination among technical advisers who visit the region to harmonise extension messages and optimise the reach of farmer communities with the available resources.
