The roots of the current supply troubles stretch back decades. In 2005, an invasive bug called the Asian citrus psyllid arrived in Florida, injecting bacteria from its saliva into the state’s orange trees. The bacteria slowly kills the tree by destroying its root systems. There’s no known cure once a tree is infected.
The impact has been devastating. In 2004, before the disease – called citrus greening – hit Florida, the state produced 200 million boxes of oranges. This year, it will produce less than 20 million.
Michael Rogers, a professor of entomology and the director of the University of Florida’s Citrus Research and Education Center, said no type of orange tree is totally resistant to greening, but scientists have been trying to breed trees that are more tolerant of it.
Citrus greening arrived in Brazil around the same time as Florida, but it has progressed more slowly there because Brazil has much larger orange groves. Bugs spread the disease by flying from tree to tree, Rogers said.
Still, the disease is spreading. Fundecitrus estimates that 38% of Brazil’s orange trees had citrus greening in 2023. Simonetti, the orange farmer, estimates that 20% of his production is affected by greening. Oranges on affected trees don't ripen properly and fall off early, affecting the quality of their juice, he said.
Shifting production to other locations isn’t necessarily an option. California grows oranges, for example, and the citrus psyllid doesn’t fare as well in the state’s climate. But California also doesn’t get the rainfall needed for juicing oranges; its oranges are usually sold for eating, Rogers said.
Another issue impacting orange harvests is extreme weather, which is becoming more common as the world warms due to climate change.
Last year, nine heat waves swept across Brazil, resulting in lower output and poorer fruit quality. This year, the impacts of El Niño have been particularly dramatic, with a historic drought in the Amazon and devastating floods in the southern state of Rio Grande do Sul.
“The temperatures are high during the day. At night the temperature drops. The plant can't stand this temperature difference,” Simonetti said.
Brazil’s 2024-2025 harvest is expected to yield 232 million boxes of oranges, down 24% from the prior year.
“We have never seen a harvest like this,” Vinícius Trombin, the coordinator of Fundecitrus’ crop estimates survey, said.
To make up for the anticipated smaller yield, some producers are considering blending oranges with tangerines to make juice, Trombin said. But he’s skeptical.
“The consumer wants an orange juice made up 100% out of oranges,” he said.
Parker, of Circana, isn’t so sure. She thinks blends with other fruits might help hold down costs and revive consumer interest in orange juice.
“The idea of multiple flavors is very popular and is a way to stand out,” she said. “You’ve got to keep people engaged. Once you lose that interest, it’s really hard to get people back.”
