What are bio stimulants?

Author: Maarten Casteleijn | Latest update: 12-02-2021
Bio stimulants are increasingly being used to strengthen crops. These are
products that have an effect on, in particular, the growth and resistance of
plants. Bio stimulants have experienced significant growth over the last few
years. These products are of natural origins, making them fit in better with an
integrated crop protection system. In this article, our specialists explain
more about bio stimulants.
How do biostimulants work?
Bio stimulants are products that positively influence
the growth and resistance of plants, resulting a higher abiotic stress tolerance (for example, drought or heat stress) and by
converting substances for easy absorption of nutrients by plants. This
ultimately ensures quality improvement in the crop.
Please note: bio
stimulants have no effect on biotic stress (i.e. diseases and pests).
The advantages of bio stimulants
The use of bio stimulants has a number of advantages:
- They contribute to a more resilient crop;
- They contribute to an improved intake of nutritional elements;
- They can contribute to a stronger root environment of the crop, which can lead to a better yield;
- Bio stimulants do not have adverse effects on
natural enemies and can therefore be used in an integrated crop protection strategy;
- Bio stimulants have a small ecological footprint;
- No
MRL is
left after using bio stimulants, which means they do not affect the MRL.
Please note: bio stimulants are not crop protection agents and therefore they
have no direct effect against diseases and pests. They work preventively by
strengthening the crop, but will not directly eliminate harmful organisms in
case of high disease or pest burdens.
Types of bio stimulants
Bio stimulants can therefore have three different
effects:
- They can reduce abiotic stress.
- They can improve nutrient absorption through the
plant.
- They can contribute to improving the overall quality of the plant.
