Brazilian citrus growers achieve progress on psyllids

Brazil’s citrus industry saw a 40% drop in the population of HLB-transmitting psyllids in 2024, a positive shift after record highs in previous years. Despite this progress, pest levels remain above what was typical between 2014 and 2019, before resistance to some insecticides became a problem, according to local media.

Experts stress that continued efforts are needed to prevent another surge. Fundecitrus warns that without proper management, the psyllid population could rise again, putting citrus crops at risk.

The pest's spread is influenced by both climate and field practices. From 2014 to 2019, psyllid numbers were low, but since 2020, resistance to pyrethroids and neonicotinoids has led to sharp increases, peaking in 2023.

To sustain the decline, growers must rotate effective insecticides and closely monitor their fields. Fundecitrus highlights the need for smart pesticide use to keep resistance in check.

Producers are encouraged to use tools that offer real-time data on insecticide performance to make informed decisions for controlling psyllids and protecting their crops.
