Trichoderma for Plants

Trichoderma for Plants

Beneficial Trichoderma fungi convey many benefits to plants. In fact, microbe plant interactions are often beneficial to the plant and in turn, beneficial to farmers and gardeners. This post will talk about the plant growth promotion benefits of these beneficial fungi.

Basics of Beneficial Fungi

First, lets start at the beginning. Trichoderma are microscopic, free living fungi typically Trichodermafound in the root zone (rhizosphere) of many plants. They are common inhabitants of both the root and soil ecosystems. They  are generally thought of as opportunistic, avirulent plant symbionts.

In fact, some species are able to colonize and grow on roots as the roots develop. For this reason, many applications  are either as seed treatments or applied as early in the growing cycle as possible.

Since Trichoderma species have a number of benefits for plants, there are a number of words use to describe these benefits such as; biofertilizer, soil probiotic, soil inoculant, biological soil enhancement and plant growth promoting fungi.

Plant Growth Promotion

For many years, it has been known that many Trichoderma species help with plant growth promotion. They, along with multiple species of Mycorhiza, are considered plant growth promoting fungi (PGPF). Enhanced root development has been seen in a number of crops including, soy beans, corn, tomatoes, peppers and rice to name a few.

Root development is key to a plants early survival as well as its nutrient uptake as the plant begins to mature.

Along with enhanced root development, beneficial soil fungi convey some additional specific benefits to plants:

  • Phosphate solubility – making phosphorus more readily available to the plant.
  • Enhanced root biomass production and enhanced root hair production.
  • Production of phytohormones – both auxins and cytokinins. These compounds are plant growth promoters.
  • Higher tolerance of the plant to stress.

All of these benefits ensure a healthier, more efficient root system, a healthier plant and a more productive crop.
