General information

Dora RootGuard is the popular biocontrol solution on Soil Micro-environment,

Diseases Control & Root System Growth. It contains trichoderma spp, Bacillus series,

Organic matters and Saccharides.

The Brightest Spotlight, it has the outstanding capacity for eliminating damaging fungal

pathogens in soil, and form a nature defensive bond to Guard and stimulate your crop’s roots.

Now they are used as bio-pesticides, bio-fertilizers, root growth stimulants and enhancers

of plant resistance.

Application Mode: Foliar sprays, pre-planting applications to seed, post-pruning treatments,

incorporation in the soil during seeding or transplant, watering by irrigation or applied as a

root drench or dip.

Suitable Plants: Fields, Greenhouses, Nurseries, Horticultural Plants, Fruits, Trees and

Ornamental Crops.

Benefits of Rootguard

1. Improve Soil Condition

Outstanding soil adaptability in soil, control soil borne pathogenes 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, Pythium, Fusarium. It will form a nature defensive bond to “Guard” your crop’s

roots.

After we used the Dora Rootguard, it will produce mycelia to grow along the roots, will forms a

physical bond on the surface of plants 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

Several research shows that trichoderma harzianum is one of the most effective microbes to

colonise the roots.

4. Increase Plant Resistance Ability

Dora Rootguard is capable of systemically activating plant defence mechanisms. In actual

use, it can increase the ability of the plant to against abiotic stresses such as drought, salinity,

high temperature.

Mechanism of Action

1. Biocontrol Mechanism

The basic mechanisms for control & against pathogens diseases including Nutrient & Space

Competition, Antibiosis, Parasitism, Inducing host-plant Resistance.

2. Soil Remediation Mechanism

Dora Leading Production Technology

Compared with solid fermentation with more contaminating microorganism and short survial

time. Our microbes series used lastest technology of liquid fermentation, with the advantages

of low contaminating microorganism rate and longer survial time.

Field Trial of Dora Rootguard

Ps: Photos all from our customers.

1.Tomato test field with problem of seriously soil salinization. After Appyling Dora Rootguard,

the salinity in soil pbviously reduce 36% and tomato’s quality and yields improved together.

2.Cucumber test field with the problem of yellow leaf diseases. Through contrast experiments,

we can observed the Dora Rootguard well worked.
