LDP makes wetting agents a key tool in the greenkeepers armoury

Understanding Wetting Agents and their Role in Combatting Localised Dry Patch (LDP)

Some wetting agents are made from harsh chemicals that can be harmful to the environment and potentially toxic to humans and animals. However, wetting agents made from biodegradable and environmentally friendly ingredients are available. These products are designed to be safe for use around people, pets, and wildlife, and they break down naturally in the soil over time, leaving no harmful residues behind.

Tackling Hydrophobic Soil and LDP: Some key research findings

The management of bowling greens often presents complex challenges, one of the most prevalent being the occurrence of localised dry patch (LDP) due to hydrophobic soil conditions. Addressing this issue effectively is crucial for the health and performance of your green and wetting agents have emerged as a key tool in this endeavour.

However, concerns have been raised about the potential toxicity of commonly used chemical wetting agents, leading to a call for safer, more environmentally friendly alternatives.

Soil water stages

Plant available water in bowling greens

The plant available water in bowling greens is determined by the physical characteristics of the soil. Most importantly the soil texture dictates the relative percentages of Macro, Meso and Micro pore space in the soil. This soil porosity also dictates the rate at which the green will drain. The balance between drainage and plant available water is one of the most critical components of a performance bowling green maintenance program. Here then is the very crux of all those arguments about top-dressing!

Fusarium

Fusarium and the Disease Triangle

Managing diseases like fusarium patch can be a challenge for bowling greenkeepers striving for healthy, high-performance turf. While fungicides provide some relief, long-term reliance can weaken natural defences and disrupt soil health. Emerging research highlights the value of PotSi as a sustainable alternative to bolster turf resilience. By strengthening cell walls, enhancing stress resistance, and activating natural defence mechanisms, potassium silicate offers a proactive approach to reducing disease severity and recurrence. Discover how integrating this innovative solution into your maintenance programme can support greener, more sustainable greens.

Phosphite Ion

Phosphite and Disease Resistance

Phosphite (PO₃³⁻) is a reduced form of phosphate (PO₄³⁻), the familiar phosphorus source in traditional fertilisers. Although the two compounds are chemically related, their behaviours in plants and soils differ significantly. Phosphite is highly soluble and readily absorbed through both roots and foliage, making it a highly efficient delivery mechanism for phosphorus-related benefits, including disease and pest resistance, acting as a trigger for some of the plant's remarkable natural defence mechanisms.
