Leaf wetting-Dew Point and DPV + Thermal Integral and Cold Hours

To the data collected in real time for more than a year and known to all: relative humidity, room temperature, thermal integral and cold hours, our engineers have added new measurement parameters: LEAF WETTING, DEW POINT and VPD.

What is the new data for: DPV-DEW POINT-WETTING OF LEAVES

Plantae weather station measuring in real time Relative Humidity, ambient temperature, DPV, cold hours, thermal integral, dew point and leaf wetting.

DPV: indicator of water stress. It allows us to know the ideal moment for the application of irrigation or fertilizer, a very interesting fact when we also know the humidity of the soil with the rest of the probes. Thanks to the DPV we will know when the transpiration of the plant is maximum or minimum.

Dew Point: prediction of the appearance of pests, especially fungal diseases. Possibility of programming foliar applications to prevent them from being washed away and ensure their efficiency.

Wetting of the leaves: essential data to make predictive models of pests and diseases.


DPV is understood as the difference between the saturation vapor pressure and the actual vapor pressure in the air. Cryptogamic diseases are those that are produced in plants by fungi or other parasites. Fungal spores pass through leaf stomata into plant cells.

Vapor pressure is a measure of the amount of vapor present in the air. When the air reaches its maximum vapor content, the vapor pressure is called the saturation vapor pressure.

The calculation of this parameter is carried out continuously with the ambient temperature and relative humidity readings collected by the Plantae weather station, being able to view the data in real time from the app or web and create alerts on the platform.

Dew point

It is the temperature to which the air must be cooled so that the water vapor condenses into frost or dew. Knowing the dew point allows us to know the hours at which the leaf is moistened and to be able to prevent diseases derived from them.

The calculation offered in the Plantae Panel is hourly, and will show its variation in real time.

Leaf wetting

Open stomata. 1-Epidermis. 2-Occlusive cell. 3-Water. 4-Core. 5-Chloroplasts. 6-Occlusive or guard cell. 7-Water. 8-Core. 9-Potassium.

These are the hours of the day when the leaf is wet.

Measuring leaf moisture is one of the most important points in disease control, especially those caused by fungi such as: mildew, powdery mildew, rust, anthracnose and mottle.

The number of hours that there is water on the leaf is calculated through equations that are solved with the data obtained from the weather station in real time, as well as the rest of the parameters.

By calculating the number of hours of wetting of the leaves, preventive applications against fungal attacks can be planned.

The goal is to receive automatic alerts.

I want to speak with an Agricultural Technician

You can only receive this data by purchasing the Plantae weather station, which you can place anywhere on the farm or on the Hub/Receiver itself, and whose cost is €349+VAT , you will now have access to information in real time. To this is added the annual cost of €60/year for the data service and all the parameters that we have explained in this article.

Contact us through the web or contact your Plantae distributor or sales representative for to provide you with all this information in detail.
