The IPM for Exportable Fruit Crops in Vietnam project implements ecologically-based, participatory integrated pest management of insect pests, pathogens, and weeds. The project targets four major economically important crops in Vietnam: dragonfruit, mango, longan, and lychee. These four crops collectively represent a major portion of Vietnamese fruit exports to the United States.
This project addresses the major production-limiting pests and diseases of dragonfruit, mango, longan, and lychee by developing ecologically-based IPM strategies and practices and disseminating them to local stakeholders.
Cultural practices such as planting density, poor canopy management, and forcing flower growth year-round, along with a dearth of IPM knowledge among farmers and exporters, adversely affects productivity and quality of fruit production in Vietnam.
Heavy pest infestations can render produced fruit unmarketable, even for domestic markets. Current measures to control these pests rely heavily on pesticides with high dose, intensive, and inappropriate applications, which increase production costs as well as pollute the environment, decrease food safety, and adversely affect human health. In addition, this practice can build up pest resistance and negatively affect the ecological system by reducing populations of antagonists to the pests.
This project will create and disseminate IPM packages for the four fruits with input from local stakeholders. In order to do this, it will strengthen farmer cooperatives, strengthen implementation of government policies, engage local stakeholders, and promote the packages through education and electronic media communication.
The Vietnamese team will be supported by an experienced team of external/international partners and other short-term consultants.
Achievements and Highlights
- With collaboration from partners at the Southern Horticultural Research Institute, the IPM IL team has identified the causative agent of longan witches’ broom syndrome as the eriophyid mite Eriophyes dimocarpi. Identification of the causative agent allows for IPM IL to recommend proper management options including application of lime sulfur and pruning of infected shoots.
- With the implementation of fruit bagging on longan, mango, and dragon fruit, farmers in Vietnam have significantly decreased pesticide applications.
Current Project Objectives
- Detect key limiting pests and diseases and analyze matrix of pests and natural enemies.
- Develop and formulate ecologically sound, farmer/community-centric IPM technologies and packages based on innovative research approaches and pragmatic designs.
- Pilot and scale-up IPM technologies to a wider target participant base (e.g. growers/farmers, fruit exporters, government regulators) along production-market chain.
- Foster participatory transferring technologies and communication activities, including exporting mobile-based approaches to create broader awareness, dissemination, and impact of IPM technologies.
- Monitor and evaluate activities focused on project outputs and outcomes with emphasis on socio-economic and gender aspects.
- Actively seek to engage women in the participatory learning process.
- Substantial reduction in pesticide use with increase in number of Good Agricultural Practices (GAP) farms.
- Increase market access (especially U.S. markets) and develop better socio-economic welfare for small land-holders, with IPM-based capacity development focused on greater gender-based considerations.
