Paraná extends phytosanitary emergency against greening for 180 days

The Government of Paraná extended the phytosanitary emergency situation for another 180 days to contain greening (HLB, caused by bacterium Candidatus Liberibacter asiaticus) in the state's orchards. Decree 10.445/25 maintains the status initiated in 2023 and ensures agility in pest control actions, considered one of the greatest threats to citrus farming.

The disease, caused by bacteria transmitted by psyllid diaphorina citri, causes deformations and premature fall of the fruits, with significant losses in production. Greening also reduces the commercial value of the fruits due to the compromised flavor, which affects both fresh consumption and industrial processing.

In recent years, actions carried out in the North and Northwest of the state, such as eradication of diseased plants, control of the insect vector and use of healthy seedlings, have helped to contain the spread of the pest. Now, efforts are focused on the Ribeira Valley, a ponkan-producing region, where a new phase of Operation Big Citrus has begun.

Adapar also held meetings with producers at the Ceasa in Curitiba to raise awareness about the signs of greening in fruits and plants. Despite confirming infected plants, technicians have not yet detected the psyllid in the region. Even so, traps were installed at several points to monitor the insect.

The absence of the vector may be linked to the presence of natural predators, a hypothesis that will be investigated in the coming days by field teams.

By extending the decree, the government intends to maintain the pace of actions and prevent the spread of the disease to new areas.
