Executive Summary

The project focuses on addressing the Potato Purple Top Compex (PPTC/CPMP Spanish acronym) problem in the Andean Region (AR), where the potato plays a fundamental role in the diet of millions of people as well as in the contribution to the agricultural sector economy. The PPTC includes the bacteria Candidatus Liberibacter solanacearum (CaLso), phytoplasmas and the potato psyllid (Bactericera cockerelli) that acts as a vector. This complex represents a serious threat to potato crops in the AR. The project proposes to learn more about the situation of the PPTC through a diagnosis in the region with the countries involved in the proposal. In addition, the molecular detection of the plant pathogens and the PPTC management strategies will be optimized, and the dissemination of the results generated to the actors of the potato value chain. At least 1,730 farmers and 370 technicians and other actors in the sector will directly benefit in training, dissemination activities and access to clean seed. The project establishes three components: i) prepare a regional diagnosis of the PPTC problem, through online events with experts and the collection of information through surveys with key actors in the value chain; ii) optimize molecular detection protocols and PPTC management strategies. This includes training laboratory workers in molecular analysis techniques, evaluation of methodologies for the detection of pathogens and disease management practices. It is expected to generate optimized laboratory protocols and technical publications on PPTC management and access to clean seed; iii) disseminate the knowledge generated about the management of the PPTC. This involves strengthening the capacities of value chain actors, organizing training events and implementing learning plots in the field. It is planned to develop scientific events, training for laboratory workers and bibliographic material, as well as dissemination and closing events to report the results of the project. Through the project's intervention, a 25% increase in yield is expected, along with a 15-20% reduction in pesticide expenditure for CPMP control, and a 50% decrease in the use of high environmental impact pesticides. In addition, greater knowledge of the PPTC is expected to prevent expansion to new areas or countries.

The technological solution

Experts from public agricultural research institutes in Ecuador, Peru, Colombia, and Chile propose to pool their resources to execute a research project aimed at strengthening knowledge in the diagnosis and management of CPMP, focusing on potato seed quality and pest management in farmers' fields. This will be achieved through the execution of three specific objectives: the first will involve conducting a regional diagnosis of the CPMP issue; the second will focus on optimizing protocols for the molecular detection of CPMP in seeds and developing management strategies for the disease in farmers' fields; finally, the third will promote the effective dissemination of knowledge generated about CPMP management. This project will involve the participation of the International Potato Center (CIP), the Inter-American Institute for Cooperation on Agriculture (IICA), phytosanitary control agencies and ministries of agriculture from the four countries, universities, educational institutes, and producers' associations.

Results

The project intervention is anticipated to reduce yield losses by an average of 25% among producers who adopt the proposed technologies. Additionally, it is expected to decrease pesticide expenditures for CPMP control by 15% to 20%. Furthermore, it is anticipated that 100% of laboratories within the phytosanitary control agencies of the respective countries will implement optimized protocols for detecting this disease. The incorporation of these analyses into the phytosanitary control system will result in a 25% reduction in losses for producers who use certified seed in each of the countries.

It is estimated that the project intervention will reduce the use of high-impact insecticides for CPMP control by 50%. Moreover, this reduction in pesticide use will be crucial for mitigating pesticide resistance in pest populations, a critical factor in sustainable pest management.
