Colloidal silver (Argentum) is an ethylene blocker and prevents ethylene from working like an auto catalyst to build up ethylene levels. This is particularly interesting in the case of hail damage and bud and flower drop, extending the flowering period.
Plants normally produce ethylene when affected by hail damage, to kill off a few cellular layers and form a scab to seal the wound. However, this has the disadvantage that development comes to a complete standstill for two to three weeks. Applying ArgicinPlus (both contain micro silver) the day after hail and repeating seven days later prevents ethylene formation. The silver keeps the wounds clean and the plants keep on growing. The result is well developed plants with a balanced volume/branch framework and appropriate stem size.
Application in cabbage crops also produces particularly good results.
Work on plants can cause wounds on the plant, with unintended ethylene production as a result. An example is the insertion of canes into Phalaenopsis pots. We therefore advise the application of silver to prevent loss of flower buds in the last few weeks of the long cultivation period.
The ethylene-blocking effect of silver continues after harvest. For example, apples that are sprayed with Argentum at least three times during the last weeks before harvesting are ‘fresher’ coming out of the cooling, especially if the crates in which they are stored are also cleaned using ArgiPura. The result, for example, is an increase in class A Golden Delicious of 30–40%, mainly due to the reduction in problems caused by Gloeosporium.
