Trial results show Trianum is your key to a healthy carrot crop

The user-friendliness and diverse crop protection that Trianum offers has made it one of the key biocontrol agents for carrot growers to boost productivity. With the unique active ingredient, Trichoderma harzianum T22, Trianum colonizes the root system of plants and protects the crop against various soil-borne diseases, including Pythium.

Trianum-P wettable granules can easily be dispersed in water and applied via drench, drip-irrigation or spraying. Growers can also apply the granulate version, Trianum-G, with a regular granular applicator attached to the sowing machines. This is similar to what is done with regular fertilization. Trianum works preventively against different soil-borne fungi such as Pythium spp. Trial results of growers using Trianum to target Pythium in carrots delivered an extremely positive average yield increase. Using Trianum, growers achieved a return ratio of €1 invested to €4.7 in profit, which is competitive with the grower standard.

How Trianum works

After the application of Trianum, the spores germinate, and the mycelium colonizes the roots of the plant. The mycelium suppresses the development of soil pathogens by competing with them for space and nutrients. It also releases secondary metabolites with an antibiotic effect on the pathogens, weakening them and facilitating the process of mycoparasitism, which develops afterward. The mycoparasitism of the pathogen and strengthening of the resistance mechanism are two added properties of the product's effectiveness against soil-borne diseases. Other very unique characteristics of Trianum are that it improves the uptake of nutrients and enhances the resistance of the plant caused by abiotic stress such as suboptimal fertilization, watering, and climate conditions. The high quality of the product, from production and formulation to storage and delivery, ensures that 100% of the spores will germinate and perform effectively in the field.

Increased yields due to effective Pythium control

Recent trials showed that Trianum-treated fields had 20% fewer Pythium infected carrots at harvest. The yield increased from 45,4 Tons/ha* to 47,92 Tons/ha, ultimately resulted in an increase in gross turnover from €13.620 to €14.376. Carrot trials in Poland, also using Trianum-P to target Pythium, showed that there were only 0,37% plant losses, which is significantly lower than the grower standard of 0,77%. Ultimately the trials emphasises that Trianum offers the quantitative and qualitative drivers to offers growers higher income per hectare.

Post-harvest protection

Trial results of Trianum-P targeting Pythium in carrots also showed positive outcomes during storage. After 2 months, the percentage of diseased carrots was 4.7%, and after 4 months, it was 4.8%, indicating a minimal increase. In comparison, the grower standard practice showed 11.7% diseased carrots after just two months of storage. This clearly demonstrates the superior performance of Trianum-P compared to other products on the market, emphasizing that the use Trianum is a key strategy for extra protection for carrots post-harvest.

It is clear why Trianum should be a key biocontrol agent for any success IPM strategy for carrot crops. Higher return on investment, increased yields and extended protection post-harvest, that is what is means to be in control with Koppert.
