harvest INTERNATIONAL® duo
fermentation and stability after opening
harvest INTERNATIONAL® duo is a combination of a homofermentative strain with a tried and tested L. buchneri. This accelerates the lowering of the pH and improves at the same time the stability of the silage. As soon as oxygen is available and the silage warms up, important nutritions vanish because of the yeast’s increasing activity.
A secure lowering of the pH is required for the possibility of letting the acetic acid, produced by the L. buchneri, fully develop its yeast and fungus inhibiting effect.
A special Lactobacillus buchneri
Lactobacillus buchneri is mainly used to improve the stability. Life in a family of bacteria is not unlike real life, as can be seen by the results of trials conducted with various strains of buchneri. Even though Paul and Henry Smith belong to the same family, Paul might be great in math while Henry is only average.
And characteristics of the different strains of buchneri differ just as widely. – The following chart illustrates the trial data of four strains of buchneri as published in EFSA* journal.
Dry matter losses
It is common knowledge that dry matter losses with Lactobacillus buchneri are higher than the ones occurring in untreated silages. The strain of Lactobacillus buchneri used in harvest INTERNATIONAL® duo and plus, however, is atypical as it significantly reduces dry matter losses. Compared to untreated silages, this efficient fermentation saves more nutrients.

Stability after opening
Through using harvest INTERNATIONAL® duo, the stock of yeast and fungus in the silage decreases immensely.
Consequently, the stability after opening enhances.
- grass silages and grass/clover mixtures > 30 % DM
- whole plant silages (WPS) from 30 % DM
- maize silages
harvest INTERNATIONAL® duo can be used for ecological and organic farming.
Dosage: 1.5 g per t
Dissolve the freeze-dried powder in a sufficient amount of water and apply evenly over the forage using the suitable amount of water for your applicator.
The mixed solution should be used up within 48 hours.
Storage and shelf life
3 months at +20 °C, 12 months at +4 °C and 18 months at -18 °C
One pouch of 150 g treats 100 t of forage.
