Trichoderma Harzianum Technical

Product Description

Trichoderma grows on the surface of roots, where it provides disease control and enhances root growth. Its spores survive in the soil, but the food it lives on is mostly secreted from the root surface. Since the fungus multiplies on its own, it is different from seed-applied fungicides.

First, only a little needs to be applied because it will grow to continually cover the roots.

Second, because it grows, it protects all the roots for the whole growing season. Chemical controls protect only the seed where they are applied, and their protection lasts, at most, a few weeks.

Once Trichoderma has colonized roots, it can improve growth in two main ways.

First, it kills the fungi that cause root rot.

Second, it protects roots from certain physical stresses, allowing the roots to grow faster.

Trichoderma kills several major root rot fungi: Pythium, Rhizoctonia, and Fusarium. The process is called mycoparasitism.

Trichoderma secretes an enzyme that dissolves the cell wall of the other fungi. It can then get inside the bad fungi and consume them. It allows it to protect crop roots against root rot fungi in the field.
