Plant Biostimulants

The new culture of stimulation of natural processes that benefit the development of plants.

Biostimulants are a complement to nutrition and crop protection.

Biostimulants influence the metabolism of plants, causing improvement in the development, vigor, yield and quality of crops, by stimulating natural processes that benefit growth and the response to abiotic stress such as high and low temperatures, lack of water, and excess salts, influencing the metabolism of plants: photosynthesis, respiration, solute transport, translocation, protein synthesis, nutrient assimilation, tissue differentiation, formation of carbohydrates, lipids, structural substances of plants .

Biostimulants have long been associated with organic or organic farming. Now, thanks to research, they have a very important role to play in conventional agriculture as a complement to nutrition and crop protection.


Plant Biostimulant


agristren plus

Agristren Plus. Optimizes the osmotic potential of the cell, maintaining the growth rate of the plant under conditions of water stress.

Neostren forte. Biostimulant corrector of physiopathies of the skin of the fruit in horticultural, fruit trees, wine vines and table grapes, such as cracking, bitter pit and creasing.

Norcaren. Biostimulant that reduces oxidative stress that causes the fall of flowers and fruits in fruit trees and vegetables. Prevents premature senescence of the ovary due to oxidative damage, thus increasing the longevity and viability of the eggs to be fertilized, increasing the “effective pollination period”.

Rental. Biostimulant that helps to overcome post-transplant stress states, favors the microbial life of the soil and root development, unblocks and improves the absorption of nutrients and favors cell division, the vegetative growth of leaves and fruits.

Treline. Biostimulant developed to enhance the sprouting process, quickly and intensively generating an abundant foliar volume that will allow the production of energy necessary for the optimal development of the crop.

Colorsave. Biostimulant for the natural coloring of fruits, which activates the biosynthesis of carotenoids and anthocyanins.

Glutabion. Biostimulant of sprouting in fruit trees, berries and vineyards. It activates the metabolic processes for obtaining the energy necessary to break dormancy and promote sprouting, so that uniformity and precocity in flowering, better fruiting and greater accumulation of sugars are achieved.

Cromar. Biostimulant of apple coloring. It favors the stabilization of anthocyanins, substances responsible for the red coloration of the fruits, minimizing their degradation due to environmental effects, achieving an increase in the colored skin surface and with more intensity of color.

Primarenc. Biostimulant of plant defenses against thermal stress. It adapts the plant to the situation of high and low temperatures, neutralizing the action of oxidative species that are generated in extreme temperature environments, thus increasing the capacity of the plant’s defense systems for better flowering and fruit setting.

Biostimulants contribute to sustainable agriculture

Feeding a growing population requires increases in yield and improved quality of crops, which are encouraged by biostimulants. Extreme temperatures, lack of water, salinity and other stresses related to climate change require resistant crops. Biostimulants increase the tolerance of plants to adverse effects of abiotic stress.

Biostimulants can improve product quality parameters. Higher quality means higher profits for farmers and healthier and more nutritious food for consumers. Biostimulants help protect and improve soil health, promoting the development of beneficial soil microorganisms. Healthy soil holds water more effectively and resists erosion better.

Biostimulants help address some of the biggest challenges facing global agriculture in the coming years.

Biostimulants contribute to socioeconomic development

Biostimulants help improve farmers’ profits, helping to ensure that applied fertilizers are actually used by crops.

Biostimulants help reduce waste throughout the agri-food chain. Less waste means lower costs, which ultimately benefits the consumer who has access to high-quality, affordable food.

Farmers are also able to obtain higher prices for their crops when the quality of the crop is higher. The quality improvement has a positive impact on storage and conservation, giving farmers more time to choose the best time to sell their crops at advantageous prices.

Companies that develop biostimulants often carry out their research in collaboration with independent universities and research institutes. This model encourages knowledge sharing and innovation and creates a demand for highly skilled researchers and other workers, thus encouraging more students to enter the fields.

Biostimulants help foster innovation and knowledge creation

Innovative green technologies are at the heart of biostimulants.

Developing a biostimulant begins by looking at plants and their ecosystems and then conducting rigorous research to discover new bioactive compounds, to identify beneficial microorganisms, and to understand how synergies provide stronger effects than any single substance or microorganism that works alone.

Many of the components of biostimulant products are very common in nature, such as amino acids, algae, humic acids, sugars, vitamins, microorganisms

Many of the technologies used have a biotechnological basis, for example, using microorganisms to transform raw materials into active components or containing microorganisms in the final product. This encourages and provides employment for highly skilled researchers and workers in life sciences.

A broad pool of qualified professionals in these fields is a necessary precondition for innovative and sustainable growth that helps Europe develop “smart, sustainable and inclusive” growth.
