Brown-patch tolerant 4turf® doesn’t leave it to chances

10/01/2022

Climate change is putting pressure on turf areas, especially on summer renovations of pitches, which are now taking place in warmer and more humid weather – optimal conditions for the growth of the pathogenic fungus brown patch. Professional turf managers therefor need to choose disease-tolerant turf varieties for their turf areas, that can safeguard their turf and give them a peace of mind. 4turf® varieties from DLF can give professional turf managers the peace of mind they are looking for, since they are more brown-patch tolerant. The more disease-tolerant the turf, the more effective and cost saving those summer renovations will be.

Football’s narrow window of opportunity for repairs

Top-class football takes place almost all year round. Apart from a brief break over the summer, the season is packed tight with matches. By season end, pitches are worn, tired, and in need of repair. These urgent stadium and training-ground renovations take place during the short match-free summer, often with the establishment of new turf.

Pitch renovation is a crucial time for grounds managers. They want their pitches renewed – to be green and healthy for players and fans to enjoy – but time is tight. There are no second chances during a summer renovation. Warmer and more humid summers create ideal conditions for brown patch which can damage the entire pitch. By choosing disease-tolerant varieties, grounds managers increase their chances of achieving a beautiful, green and healthy pitch.

Varieties tested for tolerance to brown patch

Brown patch is a turfgrass foliar disease caused by Rhizoctonia spp. The fungus can attack all cool-season turfgrasses, but is most devastating to Perennial ryegrass, Bentgrass and Tall fescue. There are many examples of damage it has caused during summer renovations of sports pitches. In the worst cases, the professional turf manager will lose all the turf on a newly established pitch, and must repeat the sowing. This inevitably leads to a postponement of the opening games of the season.

Future-proof your turf with brown-patch tolerant varieties

To minimise the chance of losing an entire newly established turf area, professional turf managers should choose mixtures containing varieties with a high brown-patch tolerance.

DLF has, through screening methods, tested a number of turf varieties and identified 4turf® varieties to be the most brown-patch tolerant. Furthermore, some of our DLF diploid Perennial ryegrass varieties GILDARA, MONROE, ANISTON, ASPIRE, and CHLOE, has shown excellent brown-patch tolerance as well.

Choose more sustainable turf

Choosing grasses with a higher disease-tolerance is also a step towards more sustainable turf maintenance. These grasses reduce your need for fungicides and herbicides. They’re less likely to be attacked by fungal diseases, which also leads to less weeds.

A reduction in pesticide consumption is a step towards the UN's sustainable development goal no. 15, which deals with the protection, restoration and sustainable use of ecosystems. A reduction in pesticide use also helps to comply with the EU directive on sustainable use of pesticides (Directive 2009/128/EC).

Varieties that are tolerant to brown patch require less maintenance. They cut maintenance costs because they’re more likely to establish well during a summer renovation, which limits the need for re-sowing or for pesticide applications. They also require less maintenance, which reduces the CO2 emission. This is a step towards fulfilling the UN sustainable development goal no.13 which is to take action to combat climate change.
