Today's agriculture faces growing challenges with rising temperatures and solar radiation resulting in episodes of heat stress, which significantly compromise crop productivity.
In this scenario, Revella sunscreen emerges as an innovative solution, based on advanced nanotechnology, capable of providing superior protection to plants against the harmful effects of radiation and high temperatures.
This revolutionary technology represents a milestone in agricultural protection, offering proven results and surpassing the efficiency of traditional sun protection methods.
The Challenges of Solar Radiation in Agriculture
Impacts of solar radiation on plants
Excessive solar radiation causes significant damage to plant tissues through complex photo-oxidative processes. Studies show that this exposure accelerates the degradation of essential pigments such as chlorophylls and anthocyanins, directly compromising the photosynthetic efficiency of plants.
The main effects of solar radiation include
- Reduced photosynthetic capacity
- Accelerated degradation of natural pigments
- Changes in fruit color
- Loss of commercial product quality
Heat Stress: A Growing Problem
Leaf temperatures above 40 °C represent a critical risk for many crops. Heat stress can cause tissue necrosis, loss of fresh mass and reduced productivity, especially in sensitive crops such as coffee, soybeans, corn, beans and fruit trees in general.
The Science Behind Revella Sunscreen
Nanotechnology Applied to Plant Protection
Revella sunscreen uses an advanced formulation based on calcium carbonate nanoparticles stabilized with organic compounds. This innovative technology combines three mechanisms of action in a single product:
- Physical protection: Effective barrier against solar radiation
- Antioxidant action: Reduces the formation of free radicals
- Nutritional support: Supply of bioavailable calcium
Functional Transparency: The Great Competitive Differential
Unlike conventional calcium carbonate-based sunscreens that form opaque white films, Revella sunscreen maintains transparency, leaving no white residue, preserving the photosynthetic capacity of the plants and the natural visual appearance of the fruit.
Proven results in different crops
Bean Experiments: Extraordinary Efficiency
Studies conducted in partnership with the Federal Technological University of Paraná (UTFPR) have shown excellent results from Revella sunscreen compared to traditional sunscreens:
Technical gains:
- Reduction of up to 3 °C in leaf temperature
- Effective protection against thermal stress
Productive gains:
- 18% increase in plant height
- 19% increase in the number of grains per plant
- Higher flower setting rate
Application efficiency:
- Dose reduction compared to conventional products
- Application of just 0.5 L/ha compared to 2.5 L/ha for traditional products
- Significant reduction in operating costs
Fruit Protection: Apples and Peppers
Results in Apples
Revella sunscreen has demonstrated superior efficacy in preserving the visual and structural quality of apples:
- Protection against UVA radiation: Preserves the natural color of green apples
- Reduction in color variation: More than 50% reduction in color variation (ΔE) compared to traditional calcium carbonate
- Thermal protection: Over 60% reduction in fresh mass loss under 50 °C stress
- Damage prevention: Preservation of the apple's visual appearance by reducing dehydration and necrosis of the skin
Performance in Peppers
Tests with peppers revealed consistent benefits:
- Maintaining the integrity of the peppers' epidermis
- Prevention of micro-injuries
- Reduction of chromatic changes
- Protection against dehydration
- Superior performance even with a dose five times lower
Technical and economic advantages
Technical Benefits
1. Functional Transparency The transparent film does not interfere with the photosynthesis process, maintaining the plant's natural productivity while offering effective protection.
2. Advanced antioxidant action In addition to the physical barrier, the product acts by reducing the formation of free radicals and preserving natural pigments such as anthocyanins and carotenoids.
3. Cell fortification Calcium nanoparticles are easily absorbed by plants, strengthening the cell wall and increasing natural resistance to environmental stresses.
Economic advantages
Reduced operating costs
- Less volume of product applied
- Significant reduction in logistics and storage costs
- Less manpower required for application
