Plant Health Department
Plant Health Department
Overview
The Plant Health Department is responsible for implementing the functions of the National Plant Protection Organization. We safeguard agriculture, natural resources and the environment from the negative impacts of regulated pests and key endemic pests that can affect agricultural production, thereby contributing to food security, and gaining market access and trade opportunities for Belize.
Plant Health Priorities
Constitutes an integral component of the plant protection system and provides technical justification for decision making in support of the regulatory system for importations. It is the principal technical and scientific to determine restrictions of commodities of very high risk and to decide on the conditions for importation for proposed importations.
Import permits are issued with phytosanitary import conditions gathered on the basis of conclusions reached by using an appropriate pest risk analysis or evaluation of available scientific information. These permits are emitted with the intention of preventing the introduction of quarantine pests or limit the entry of regulated non-quarantine pests with imported commodities and other regulated articles.
Plant Health is responsible for maintaining a favorable phytosanitary status of the country. It is also the official point for notification of pest outbreaks. These activities are carried out through surveillance programmes, either active or passive and continuous or periodic.
The introduction of quarantine pests endanger our agricultural production systems through outbreaks that can reduce yields or devastate crops and natural ecosystems. Similarly, these can have a great impact on trade due to the imposition of new condition or sanctions and potential loss of export markets. The department is always vigilant and acts rapidly in cases of new outbreaks, to eradicate these pests or if not possible to maintain sound management programmes to reduce the impact of these.
One of the most successful programmes in this respect has been the maintenance of pest free status for the Mediterranean Fruitfly, a programm now spanning many decades. This has provided the opportunity for new industries such as the papaya and habanero pepper industries.
When quarantine pests are introduced and discovered promptly, the affected areas are delimited and checkpoints are established to prevent the mobilization of these pests to other free areas. This goes hand in hand with eradication programmes.
Strict control over certain planting material is maintained for established periods of time after entry, to observe any manifestation of systemic pests. This is done in collaboration with the relevant industries as a measure to safeguard the principal productive sectors of the country.
Plant Health investigates pest situations and outbreaks in the field either to evaluate the impact of these on crops or to corroborate if these are endemic pests or may be newly introduced pests. Producers are advised on management options to minimize losses.
Plant Health personnel identify pests to verify field samples, samples submitted from surveillance programmes, and samples of interceptions from the points of entry submitted by the Quarantine Department. In cases when the capacity for identification of certain pests is not available in-house, the department sends samples to reference laboratories in the region for final diagnosis.
One of the most successful programmes in this respect has been the maintenance of pest free status for the Mediterranean Fruitfly, a programme now spanning many decades. This has provided the opportunity for new industries such as the papaya and habanero pepper industries.

Plant Health personnel identify pests to verify field samples, samples submitted from surveillance programmes, and samples of interceptions from the points of entry submitted by the Quarantine Department. In cases when the capacity for identification of certain pests is not available in-house, the department sends samples to reference laboratories in the region for final diagnosis.
Department personnel participate in several national committees and ad-hoc groups on aspects of work related to our mandate. The department personnel represent the BAHA and Belize at regional and international meetings and training events. In some cases, personnel form part of regional/ international committees in plant protection, biosafety and associated activities.
The department provides diagnostic services and technical assistance in pest management to small and medium sized scale farmers. This is done through training programmes in collaboration with the extension department of the Ministry of Agriculture Food Security and Enterprise (MAFSE).
