What is Tricho Immun doing in the forest?

As you’ve come to expect from us, we report on research and experimental findings from time to time. This time Tricho Immun We tested a biostimulant on an acacia plantation at the time of planting. Please do have a look Dr Erzsébet Karaffa, written by a professor at the University of Debrecen.

💚 Tricho Immun biostimulant effect

Researchers from the University of Debrecen and the University of Sopron investigated the effect of biostimulant treatment on a newly planted black locust stand in the Debrecen-Haláp area, on humus-rich sandy soil. The 2024 growing season was characterised by severe drought. The roots of the two-year-old black locust seedlings were soaked for 24 hours prior to planting in Tricho Immun (Danuba) in an aqueous suspension of 1%, which contains two specialised endophytic strains (Trichoderma afroharzianum TR04 and Trichoderma simmonsii (TR05) is included.

Why was it necessary to investigate this?

The black locust is a fast-growing tree species with a wide tolerance range, but in the initial period following planting, drought can cause significant losses and slow growth. Researchers have developed a natural fungus-based preparation (Tricho Immun) has been tested, which helps trees to establish roots early and survive.

How did the Tricho Immun the black locust?

Before planting, the roots of the saplings were soaked in a solution containing beneficial fungi. In late spring (at the end of May), the treated stand showed spectacular growth compared with the control group:

• the small trees that have been treated they were a quarter (25,75%) higher
• and the their stems have also thickened by more than 20%, which means better mechanical stability and more efficient water transport.
• 💚 chlorophyll content of the leaves (SPAD) measured at 9.1%, whilst the NDVI (normalised differential vegetation index) It was 11.1% higher, demonstrating better foliage health and photosynthetic capacity.

Survival is rare during a drought

When the intense summer heat and drought set in, edible mushrooms (particularly the Tricho Immun) helped the plants to manage their water use efficiently. Although the difference in height had evened out by the end of the season due to late-summer pruning and damage caused by wildlife, the treated saplings entered the winter with a much more stable base (a stronger root collar).

The lesson from the small garden

„Priming” the roots of trees before planting is an environmentally friendly, sustainable and reliable method of ensuring that our saplings take root firmly even in poorer-quality, sandy soils and can withstand the drought caused by climate change.

Tip: It further increases the chances of germination and, later on, improves the seedling’s uptake of water and nutrients if, at the time of planting, MikoMax Garden We also sprinkle mycorrhiza into the planting hole!
