ROOT GUARD Experimental tests BETTER ROOTING IN BIOTIC STRESS CONDITIONS

Fluid organic fertilizer based on amino acids, Trichoderma harzianum, seaweeds and humic acids. Allowed in organic agriculture. - stronger resistance against soil pathogens - bigger roots volume - better yields Root Guard is a product with a high level of technological innovation, combining its nutritional action with both growth promoting features as well as the action of a microorganism from rhizosphere (Trichoderma harzianum). Different experimental tests have proved that such microorganism is able to establish a mutual symbiosis with the plant and to limit the development of pathogens through...

Plants with a well-developed root system and a better interaction with microorganisms will have a stronger resistance against biotic and abiotic stress. The symbiotic interactions with the rhizosphere will allow plants to create a root system going deeper into the soil, with a consequent better use of nutrients.

Experimental results Tomato crops in growth chamber MATERIALS AND METHODS Species Solanum lycopersicum var. Cuore di bue Experimental design Fully randomized blocks Test Duration 4 weeks Temperature 19 °C (night) and 23 °C (day-time) Relative humidity 65-75% Light 14 hours Substratum Peat Method of administration Fertigation Compared treatments Number of applications Root Guard 20 l/ha and Control 3 (once a week) ROOTS VOLUME FIG 1 - Roots volume in two compared treatments. Root Guard increases the roots volume thanks to seaweeds and amino acids. A bigger roots system reaches a larger portion...

FRESH WEIGHT FIG 2 - Fresh weight per plot in two compared treatments. FIG 3 - Dry weight per plot in two compared treatments. Root Guard increases both fresh and dry weights, leading to a major absorption of nutrients and to a better nutritional condition of plants, thus achieving more profitable yields.

Experimental results Zucchiniin growth chamber MATERIALS AND METHODS Species Cucumis melo var. Ortano Experimental design Fully randomized blocks Test duration FIG 1 - Flowers number per plot in two compared treatments. Root Guard favours a higher flowers number per experimental plot, thus increasing the final production.

ROOTS VOLUME INDEX Root Guard increases the roots volume, as showed in its values index above. Such result comes from the presence of seaweeds and Trichoderma harzianum inside, which allow a higher expansion into the rhizosphere with a consequent improvement of both nutritional and phytosanitary status of plants. FRESH WEIGHT 0 889 1086 g FIG 3 - Fresh weight per plot in two compared treatments. Root Guard increases the fresh weight per experimental plot, leading to bigger production and more profitable yields.
