Effect of Terra-Sorb® Biostimulant on mitigating the phytotoxicity of the herbicide on extensive crops

Herbicides commonly used in agriculture to control weeds often cause negative effects on crops. On the other hand, biostimulants have the ability to increase tolerance to a series of abiotic stresses, but there is very limited information on their effects on plants stressed by herbicides. With the objective of verifying whether the application of the biostimulant Terra-Sorb®, based on L-α-amino acids, is capable of reducing the phytotoxicity produced by a herbicide based on Imazamox, as well as elucidating its mode of action, a study was carried out. cultivation chamber test on sunflower plants. Plants were treated with Pulsar® 40 (4% Imazamox) alone and in combination with Terra-Sorb®. The results show that plants treated with the herbicide in combination with Terra-Sorb® had greater growth, their photosynthetic activity was protected and they did not suffer oxidative stress.

Additionally, field efficacy trials were carried out in extensive crops (corn, wheat, soybeans and sunflower) comparing the productive performance of the application of the herbicide alone in comparison with the application combined with the biostimulant. In all cases the productive yield (Kg/Ha) with the biostimulant was statistically higher compared to the application of the herbicide alone.
