Resonac’s Biostimulants (KROPICO)
What is Biostimulants?
A biostimulant is a product made from natural or synthetic ingredients that helps plants grow stronger and healthier. Unlike fertilizers, which supply nutrients, or pesticides, which protect against pests, biostimulants work by stimulating the plant’s natural processes. They improve nutrient absorption, increase resistance to environmental stress such as drought or heat, and support better overall plant development. By enhancing the plant’s own potential, biostimulants contribute to higher crop quality and yield in a sustainable way.
What is Resonac’s Biostimulants (KROPICO)?
Resonac’s biostimulant, KROPICO, is the world’s first biostimulant product formulated with several types of oligosaccharides, each offering different functions. It contains no synthetic chemicals and is made only from naturally derived ingredients, making it a sustainable solution that is safe for both living organisms and the environment. When applied by foliar spraying or overhead irrigation at a 1,000-fold dilution, KROPICO promotes root development, enhances plant growth, and supports healthy cultivation across a wide range of crops. In this way, it contributes to sustainable farming practices and helps agricultural producers improve their productivity.
Product Features of KROPICO
The beneficial effects of the oligosaccharides in KROPICO are supported by a clearly defined scientific mechanism. This innovation was made possible through collaborative research with renowned academic institutions, including Nagoya University and Hokkaido University.
- It helps increase crop yields by improving fertilizer use efficiency.
- It enhances root development, photosynthesis, and fruit set in plants.
- It alleviates environmental stresses such as heat, cold, drought, excessive rainfall, or lack of sunlight.
- It supports the healthy growth of crops.
