Time Lapsed Video of Root Growth

Here’s a short video about soybeans. This time lapsed film shows Biota Max™, with Trichoderma, on the right side and untreated on the left side.

There are three main things to notice in the video.

  • First, the treated seeds germinate faster,
  • Next, notice the bigger, more developed root system on the treated side,
  • Finally, more of the treated seeds germinate.

Applying Trichoderma

Trichodermas are best applied as early in the growing season as possible. With transplants, apply at the time of transplantation. In most circumstances, one application per growing cycle is all thats required.
