How does thermal weed management kill plants?

Thermal weed management works by briefly exposing plant leaves to a temperature of around 80°C. This intense heat causes the cells in the plant leaf to burst, rendering the plant incapable of converting light energy into chemical energy (photosynthesis). This effectively causes the plant to starve, leading to its demise. Visible scorching is not required for terminal damage.

Is it necessary for a plant to be visibly scorched for thermal weed management to be effective?

No, it is a common misconception that a plant must be visibly scorched to suffer. A plant leaf only needs to be briefly exposed to a temperature of approximately 80°C to sustain terminal damage. This exposure bursts the cells in the leaf, preventing the plant from performing photosynthesis and ultimately leading to its starvation.

What types of thermal weed management solutions does Kersten offer?

Kersten offers various thermal weed management solutions including Ripagreen Thermal Lances, Hoaf Weed Burners, Eco Weedkiller Hot Water systems, and Electric Weeding Equipment. These solutions utilize either hot water or hot air techniques to effectively manage and control unwanted plant growth on different surfaces and in various applications.

Is hot air considered an ecological method for thermal weed control?

Yes, hot air is likely the most ecological thermal weed control method. This technique, along with hot water, offers an environmentally friendly alternative to traditional inorganic chemicals for managing weeds. It works by damaging plant cells with heat, thus stopping photosynthesis and leading to the plant's eventual starvation without chemical intervention.

Q: On which types of plants is thermal weed management most effective?

Thermal weed management is most effective on young, fleshy, hungry plants. It is less effective on old, established woody plants, as they may have sufficient amounts of stored energy in their stems and roots to overcome temporary food shortages caused by the thermal treatment. The method targets the plant's ability to photosynthesize.

Overview

The use of heat to control unwanted plant growth has been around for many years and was certainly in use before the widespread use of inorganic chemicals. A common misconception is that the plant has to be visibly scorched before it will suffer. The fact is, a plant leaf only has to be briefly exposed to a temperature of around 80°C to suffer terminal damage.

This exposure to severe heat bursts the cells in the plant leaf. This in turn renders the plant incapable of converting light energy in to chemical energy (Photosynthesis) effectively causing starvation.

Further thought and research on this subject will reveal this method is most effective on young, fleshy, hungry plants rather than old established woody plants, which may have sufficient amounts of stored energy in their stems and roots to overcome temporary food shortages.
