The key to a Giant Pumpkin is a healthy plant!  

This new formulation of Rootshield Plus+ contains two active ingredients: the patented Trichoderma harzianum strain T-22, and Trichoderma virens G-41. These two strains are 100% compatible with Mycorrhizae. Rootshield Plus+ provides 3 months of preventative control of major root diseases such as Fusarium, Phytophthora, Rhizoctonia, Thielaviopsis, and Cylindrocladium, and improved suppression of the aggressive hot season Pythium.  Rootshield Plus+ is a great tool to help keep all plants healthy.


When Rootshield Plus+ is mixed with water at 6 ounces per 100 gallons of water, over 150 billion spores are applied in one application. The spores germinate in 16 to 24 hours. As the Mycelium emerges from the spore, it immediately starts coiling around the plants roots and any plant pathogen propagules present. After 24 hours Rootshield Plus+ cannot be leached from the soil.

Rootshield Plus+ has two primary modes of action: (1) competitive exclusion, which means Rootshield Plus+ gets to the pathogen preferred sites first and prevents diseases from getting into the roots, and (2) mycoparasitism whereby Rootshield Plus+ encounters a pathogen mycelial strand, and secretes enzymes, including chitinases and glucanases, that dissolve the invading pathogen’s cell walls.

Rootshield Plus+ is available in granular and water soluble forms.  We have made arrangements to secure factory fresh product for each individual order. Please allow a little extra time for delivery.  We recommend storage in a refrigerator or freezer to increase longevity of the product.  


You can water Rootshield Plus+ into the pots and when setting the plant out. The granules can be added to the starting mix and tilled into the growing beds.

6 ounces will make 100 gallons of ready-to-use solution for giant pumpkins.
