NanoCalne - nano protection and nourishment for the garden

New generation calcium nanohydroxide: reflects sunlight, provides calcium and protects against pests. Transform the protection of fruit trees and grapes with an active approach to plant health

What are the causes of cracks and burns on fruit?

Summer heat can cause sunburn on apples, pears and peaches, resulting in significant yield losses. Damaged fruits lose their attractiveness, which negatively affects their market value. In addition, heat stress causes closure of the stomata, which reduces photosynthesis and leads to moisture deficiency, making fruits smaller and with thin skins. Calcium deficiency also aggravates the situation

NanoCalne® offers a holistic solution to improve fruit quality. This calcium nanohydroxide penetrates the plants, providing essential calcium and strengthening the cells. The white film reflects up to 95% of the sun's rays, lowering temperatures and preventing pathogen access. Additional ingredients such as silicon and trace elements enhance defense mechanisms, promoting the growth of strong, healthy plants

Benefits of NanoCalne®

NanoCalne® combines passive protection (like kaolin) with active nutrition and biostimulation. Kaolin mainly reflects sunlight, but it does not provide calcium, does not penetrate tissues, and has no fungicidal effect. NanoCalne® supplies highly available calcium that leaves can absorb within hours, strengthens cells from the inside, and activates enzymes that improve tolerance to heat, drought, and cold. The film lasts longer thanks to better adhesion, withstands several heavy rains, and does not clog stomata—photosynthesis continues even in hot weather. It also acts as a barrier against fungi and some pests, reducing the need for chemical fungicides.

How NanoCalne® works in the orchard day by day

Particles of 0–5 μm enter leaves through stomata and release Ca²⁺ and OH⁻: calcium strengthens cell walls, while hydroxide ions slightly raise pH, activating defensive enzymes and metabolism. This gives plants an internal “shield” against heat stress and Ca deficiency. Particles of 5–20 μm create a dense white, highly reflective film on the surface—fruit stays cooler, sunburn is reduced, and the skin becomes thicker and more elastic. NanoCalne® can also facilitate CO₂ movement, supporting photosynthesis, and acts as a mild biostimulant—trees tolerate frosts down to –5 °C (at 1–2% concentration) and recover faster after weather stress.

Easy application and safety

NanoCalne® is mixed at 1–3% (10–30 kg per 1000 L of water) and can be used with any sprayer without clogging risk. Apply like a standard protectant—onto leaves, trunk, and fruit. Environmentally friendly: lime-based, does not contaminate groundwater, and is safe for bees and beneficial insects. Typically 3–5 applications per season are recommended: spring (frost protection and early disease pressure), May–June (during fruit growth), and July–August (peak heat). Start with a trial block—compare it with a control and you can see the difference in fruit quality within the same season.
