WHAT IS THE DIFFERENCE BETWEEN ROOTSHIELD PLUS+ AND ROOTSHIELD?

RootShield’s active ingredient is Trichoderma harzianum strain T-22, which provides preventative control of Pythium, Fusarium, Rhizoctonia, Cylindrocladium, and Thielaviopsis species.

RootShield PLUS+ contains an additional active ingredient: Trichoderma virens strain G-41. This active broadens the disease spectrum to include Phytophthora spp. and provides better control of hot season Pythium spp. (e.g., Pythium aphanidermatum).

WHAT IS THE DIFFERENCE BETWEEN THE WP AND GRANULE FORMULATIONS?

WP is a wettable powder that is added to water then mixed and applied as a drench, pre-plant dip, or through greenhouse or field chemigation (please read labels for details).

Granules are to be incorporated (mixed in) into growing mix or field soil.

WHAT IS THE BEST APPLICATION METHOD FOR THE WP?

A soil drench using an inline injector at 1:100 ratio is a common and effective method.

The WP formulations may be applied as a drench, pre-plant dip, or through greenhouse or field chemigation, depending on your specific application – please read product labels for complete application details.
