Frequently Asked Questions

What is the mode of action of Polyversum?

PO kills pathogens by coparasitism and induces plant resistance through small molecules. It also produces tryptamine to support plant and root growth.

What types of parasitism does Polyversum employ?

Mainly coparasitism; it also indirectly affects pathogens by triggering plant resistance.

How long does the product remain active on plant surfaces and in the soil?

Biomass peaks 3–5 days after application and gradually declines over about a month.

Is Polyversum effective against bacterial diseases and Pythium-related diseases (e.g., in sugar beet)?

Yes, effective against certain bacteria via plant resistance induction and excellent against Pythium-related diseases.

What is the optimal temperature range for application?

Optimal is 20–30 °C, but PO can grow between 5–40 °C and resumes activity after cooler periods.

Can Polyversum multiply in water while preparing the solution,and is prolonged activation before spraying beneficial?

It does not multiply in water, and applications should occur within 24 hours of mixing.

What are the recommended doses and application sequences for controlling root rots and in greenhouse cultivation?

Seed/seedling treatment followed by drip irrigation or spraying is recommended. PO works well in greenhouses.

What is the recommended protocol for seed treatment (dose, method, compatibility), and are adjuvants or wetting agents needed?

Dry or wet coating at 0.1–1 kg/t for cereals/soy/sugar beet/potatoes, 5 g/kg for vegetables; apply as a sole fungicide. Adjuvants like Silwet can be used but are not essential.

Which fertilizers and chemical fungicides are incompatible with Polyversum, and are there any known negative or side effects?

Most fertilizers compatible; avoid oomycete fungicides and Trichoderma. Rare minor effects include tiny brown spots in sensitive crops, and proper sprayer maintenance is needed to prevent clogging.
