PUBLIC PRESENTATION

Rotation with non-host crops to reduce soil

populations through natural decline

Weed control: control weeds that can be a host to

beet cyst nematodes

Trap crops: a crop that attracts nematodes but often

does not allow them to develop successfully

Beet cyst nematode tolerant or resistant varieties

Application of foliar, soil or seed applied chemicals or

biologicals that also fit into a integrated management

program and are helpful in the control of BCN

populations

Currently 20% of all acres are planted with nematode tolerant varieties

By 2022, nematodes will drive 30% of planting decisions (342,000 acres).

Postioning of Clariva pn (Pasteuria nishizawae) as a seed-applied biological

control agent for enhanced BCN control on nematode tolerant sugar beet varieties.

PUBLIC PRESENTATION

Clariva pn Technology - Breakthrough Innovation for Nematode Control

Pasteuria is a natural enemy and obligate parasite of nematodes

with scientifically proven activity against several nematode species

Key features:

Very specific to target nematodes

Compatible with standard seed treatments

Lethal to nematodes – instant action resulting in

reduced reproduction and death of the nematodes

Works under all conditions, independent of soil pH,

temperature, moisture

Summary

• A natural nematicide delivered as a seed treatment,

efficient and reliable under all growing conditions

• Complements conventional control options

Greatly enhances performance of tolerant varieties

• Key benefits:

Higher yield potential at harvest from season-long protection

and activity

Better equipped for crop stress through optimized root health

and plant vigor

Help to stabilize yields across a wide range of growing

conditions
