Sprouting inducers for grapevines and apple trees

Temperate climate fruit trees grown in subtropical and tropical regions need artificial stimulation to start the production cycle. For these plants to start a new cycle in spring, they need to be exposed to a period of cold, which varies for each species and cultivar. In these regions where they don’t have the necessary cold demand, the use of sprout inducers is essential to improve the uniformity of the sprouts and, subsequently, their production. Hydrogen cyanamide is the most widely used active ingredient for inducing sprouting in temperate fruit trees, especially grapevines and apple trees, but it is a highly toxic product, both for the applicator and the environment. As a result, the search for alternative products for inducing sprouting in temperate fruit trees is of great interest to growers and researchers, who have discovered alternatives such as garlic extract and later garlic stick hydrolate.
