• Late frost protection

HORTIBAC tricis

 

 

In fruit orchards and vineyards, potential yields are often endangered by late frosts during the blossoming period. Annual losses of cultivated plants, e.g. fruit and vegetables, due to frost damage can run into millions. Spring frosts, which need only reach temperatures slightly below 0 °C, are especially detrimental to yields.

 

Damages on wine from late frostThe State Educational and Research Institute for Wine and Fruit-growing (consultants: Ecological Fruit-growing e.V.) have carried out field trials with Hortibac tricis for three vegetation periods.
In 1997, the complete harvest in the region of Baden was destroyed due to spring frosts. Our contacts emphasize the urgent commercial need for a product such as Hortibac tricis, since conventional substances for frost control are expensive and not ecologically sound.

Conventional frost control methods such as sprinklers or heaters are resource- and cost-intensive and usually impractical for the whole area under cultivation. Their aim is also to stop the transition of water from liquid to a solid state. Water requires crystallisation particles to complete this transition and freeze. If none or only few are present, the ice-formation is stopped or delayed. Certain micro-organisms are ice-nucleation active, i.e. form ice crystals already at temperatures only slightly below 0 °C. If these microorganisms are suppressed by competitive exclusion, the temperature at which ice forms sinks, since fewer crystals are available.

Hortibac tricis, based on this natural principle, can prevent the formation of cell-destroying ice-nucleation particles in plants.The product can be applied by conventional spraying and achieves frost control down to -4 °C.

The Iranian government was involved in the idea for this product and its solution Iran as the largest pistachio exporteur world-wide has high annual lossses due to frost. It was this considerable economic factor that convinced the Iranian government to support cooperation between scientific institutions in Iran and Plantbacter.

Trials in the Hebei Province of China with sugar beet revealed a 46 % increase in yield by the use of Hortibac tricis, which reduced damage by frost.

At the same time trials were made with potatoes. Here, the leaves of the treated plants showed 33 % less damage as compared to those of untreated plants. In the second frost phase, 45 % less damage to the stalks was found on the treated as compared to the untreated plants.

It was shown that the use of Hortibac tricis improves the profitability of the potato plants. Furthermore the weight of the tubers was increased.
