Each biostimulant was tested at a low rate and high rate, to represent the lower and upper rates being applied to different crops in various situations [...] germination can be adversely affected by environmental conditions, and the rate of development within the host can be slow. This can lead to reduced efficacy [...] phylloplane conditions, which in turn could lead to improved infection rates and establishment in vivo. Vidi Fortum® Bulletin 010122. Copyright 2022
