Pest pressure and disease reduce tomato greenhouse yields in Paraná

As we provide the news for free, we are relying on revenues from our banners. This follows drier weather conditions in previous months, along with some cases of bacterial canker as humidity increased during March.
Between January and February, hot and dry weather in the region favoured the incidence of whiteflies in the fields and, consequently, geminiviruses. However, the impact was mitigated as, in the 2026 season, growers invested more in resistant or tolerant varieties to the virus to limit production losses.
Dry conditions also increased pressure from leafminers, requiring more frequent pesticide applications for effective management. From March onwards, higher rainfall volumes reduced pest incidence in the fields.
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.
