Smoke cannons for protecting plants from frost and overheating
DREVO Climate Protection— a set of technologies for protecting orchards, nurseries, vineyards, and young forest plantations from extreme temperatures.
The system combines smoke cannons, fog generators, microclimate monitoring, and intelligent control, reducing the risk of plant damage from both spring frosts and summer heat waves.
The main goal is not to fight nature, but to mitigate extreme conditions, preserving crops and young trees.
1. Protection from spring frosts
During radiation frosts (a clear, windless night), plants quickly lose heat, radiating it into the atmosphere.
A smoke screen can:
reduce heat loss due to radiation;
slow down the cooling of the ground layer of air a little;
reduce the rate of frost formation;
protect young leaves, flowers and buds.
The greatest effect is achieved only in combination with other methods.
TREVO Frost Smoke System
The system includes:
mobile smoke cannons;
stationary smoke generators;
automatic start based on sensor data;
control via DREVO AI;
safe fuel with minimal harmful emissions.
2. Protection from heat
In summer the main problems become:
overheating of leaves;
sunburn;
overheating of fruits;
excessive evaporation of moisture.
For these conditions, the following are more effective:
water mist generators;
temporary shading;
reflective screens;
agrovoltaic structures;
mulching;
drip irrigation.
It is not advisable to use smoke as a permanent means of protection from heat.
3. DREVO Cooling Mist
For hot weather, a fine mist system is recommended.
It provides:
decrease in air temperature around plants;
decrease in leaf temperature;
increase in humidity;
reducing water stress;
protection of young seedlings.
4. DREVO Smart Shade
The temporary shading system includes:
automatic grids;
adjustable screens;
lightweight reflective panels;
mobile canopies;
solar panels with adjustable transparency (agrovoltaics).
5. Automatic control
DREVO AI analyzes:
air temperature;
leaf temperature;
humidity;
wind speed;
dew point;
weather forecast;
probability of frost;
intensity of solar radiation.
Based on this data, the system automatically:
Turns on smoke cannons when there is a risk of radiation frost;
starts fog generators when overheated;
opens or closes shading screens;
warns the staff.
6. Limitations of smoke cannons
Smoke cannons are most effective:
in calm weather;
under clear skies;
during radiation frosts.
Their effectiveness is sharply reduced:
in strong winds;
during advective frosts (arrival of a cold air mass);
in severe frosts;
in large open areas without additional protection methods.
Therefore, smoke cannons should not be considered as the only means of protection.
7. Comprehensive protection system
For maximum effectiveness, a combination of:
smoke cannons;
wind machines;
sprinkling (where possible);
fog generators;
shading nets;
mulch;
drip irrigation;
DREVO AI monitoring.
The main principle
The best results are achieved not by a single device, but by a combination of several technologies that operate automatically depending on weather conditions.
In the systemDREVO Climate ProtectionSmoke cannons are used primarily to combat spring radiation frosts, while in summer the main means of protection become shading, water fog, and microclimate control.
