Brazil: Greenhouse crops record good yields in Northern Paraná In Northern Paraná (PR), producers of greenhouse-grown crops, with year-round production, continue to report higher pest pressure, especially from whiteflies and leafminers, due to drier weather in previous months, along with some cases of bacterial canker as humidity increased throughout March.
As a result, between January and February, the hot and dry weather in the region favored the incidence of whiteflies in the fields, and consequently geminiviruses. However, the damage was mitigated by the fact that, in the 2026 season, growers opted to invest more in resistant/tolerant varieties to the virus as a way to prevent greater production losses.
The dry weather, as mentioned, also increased pressure from leafminers, requiring more frequent pesticide applications for proper management. From March onward, higher rainfall volumes reduced pest incidence in the fields; however, according to surveyed agents, the presence of whiteflies remains significant, mainly due to soybean harvests in the region.
Why this matters: For operators, the real question is whether the sensing, control, or data layer creates faster and better decisions. The facilities that win are the ones that turn visibility into tighter control and tighter control into better outcomes.
Frequently Asked Questions
Why does LED fixture selection matter in controlled environment agriculture?
Lighting decisions affect both crop performance and energy intensity. Fixture efficiency, spectral control, and placement all influence how much value a facility gets from every kilowatt-hour.
What should growers evaluate before adopting new LED systems?
Growers should look at fixture efficiency, controllability, crop-specific use case, integration with existing controls, and the operational payback period instead of treating lighting as a standalone hardware purchase.
