The start of the growing season is of vital importance to the success of a season. Bionur-Europe recently conducted research on the application of its product in growing young planting material. The tests were performed at Proeftuin Zwaagdijk as a follow-up of earlier trials tested on seedlings.
"The aim of the research was the enhancement of microbial life in rock wool slabs and the effect of the route of administration," tells Piet Schilder of Bionur. "The research was set up with cherry tomatoes. The plants were monitored over a period of three months."
After a few weeks the differences between the treated and untreated plants became obvious:
- a significant improvement in coloration of the treated plants. The plants were vigorous and fresh green. The untreated plants showed a dull green colour and sluggishness.
- resistance against powdery mildew in the treated plants. Despite the fact that the plants were standing next to the untreated group which were infected by the powdery mildew.
The research shows that the best results are obtained when treated every two to three weeks with a maintenance dosage of Bionur.
The test set-up
Left: BIONUR group with fresh and vigorous leaves. Right: untreated group infected with powdery mildew.
"The results reinforce the mode of action of Bionur as an enhancer of the bacterial growth conditions of the plant," explained Schilder. "As a consequence, the absorption of nutrients are improved and the resistance against infections heightened. This experiment shows that Bionur can be implemented in growing on rockwool."

Bionur is successfully implemented in Europe in different types of cultivation. Bionur-Europe is introducing the product on the Dutch market.
