Directions for use

Application

Combine one part Vici Rhyzo WG with five parts water
Mix thoroughly in a clean container
Add sufficient water to the suspended solution to achieve the final spray/drench volume for desired application
It is necessary to agitate the solution regularly to ensure the spores remain suspended and are evenly distributed
Apply the watering suspension on the same day. Vici Rhyzo WG can be used without special irrigation equipment
Use sufficient volume to guarantee good penetration of the culture medium or the soil, but avoid run-off and excess drainage.
Clean thoroughly after use.

Drip irrigation:

Combine one part Vici Rhyzo WG with five parts water
Mix thoroughly.
Add enough water to the suspension to achieve the final application amount desired.
It is necessary to stir the mixture regularly to ensure that the spores are evenly distributed (the spores do not entirely dissolve in water and could settle in the container).
The spores in Vici Rhyzo WG should reach the roots quickly (immediate application is recommended in order to avoid the deterioration of the spores over time).
Do not apply Vici Rhyzo WG through a sand filter and make sure that the drip irrigation filters are clean (the spores could bind to organic material in the filters).
