Benefits of Root Guard

1. Improve Soil Condition

Outstanding soil adaptability in soil, control soil-borne pathogens and help soil build a stable granular structure, which is porous & full of nutrition and preserve moisture and fertility.

Improve soil problems such as soil salinization, hardening and acidification conditions. Reduce heavy metals & organic pollutants.  

Significantly improve soil micro-environment and fertility.

2. Bio Diseases Control

Trichoderma harzianum can eliminate damaging fungal pathogens, such as Phytophthora, Rhizoctonia solani, Pythium, Fusarium. It will form a nature defensive bond to “Guard” your crop’s roots.

After we used the Dora Root Guard, it will produce mycelia to grow along with the roots, will form a physical bond on the surface of the plant’s root system, establishing itself in the rhizosphere(root zone) and protects the roots against soil-borne diseases.

3. Stimulate Root Growth

Trichoderma harzianum promotes crop growth in three main ways:

  • Control the fungus which causes root rot
  • Reduces the physical stress on the crop and makes it grow better
  • Secrete organic acids and natural growth hormones to promote the growth of crop roots system

Researches show that Trichoderma harzianum is one of the most effective microbes to colonize the roots.

4. Increase Plant Resistance Ability

Dora Root Guard is capable of systemically activating plant defense mechanisms. In actual use, it can increase the ability of the plant against abiotic stresses such as drought, salinity, high temperature.
