Because in both cases (Leptospaeria maculans, Sclerotinia sclerotiorum) the efficiciency of Polyversum overmatched in average efficiciency of chemical standards, we can discuss Polyverum as comparable to the referential preparations.

Seed Treatmant:
The seed can be dressed in dressing machines. The dose is 2grams per kg of seed

Field Treatments:
For winter canola are recommended three sprays. First treatment is recommended in the autumn 14 days after emerging of plants. The second treatment is recommended in the spring when temperature is up 10 degrees of Celsius. The third treatment follows after 2-3 weeks.
For summer canola are recommended two sprays. First treatment is recommended in the month after emerging of plants. The second treatment follows after 2-3 weeks.
The spray volume is 100g of POLYVERSUM? per hectare (10 000 m2) in minimum amount of 400Lwater.
Mix Tank Recommendations: The dose for whole sprayers tank mix with water in a small vessel (15 l bucket) and stir well. Then fill mixing tank one-half full of water, content of used vessel recast through fine sieve to the tank and add remaining water to the sprayer. The preparation is possible spray with liquid fertilizers, herbicides and insecticides.
