In this experiment we wanted to highlight the effectiveness of the formulation Pochar on the control of nematode population in the cultivation of the potato, compared to the control in which the company has not been performed treatments.

Overview and objective

The product has been tested several times in vegetable crops in greenhouses, then there has been the effectiveness of the formulation in an arable farming with new application methods than normal use in fertigation.

Conclusioni

We can assert that the administration of Pochar on potato grown in open fields has been very effective in controlling the spread of nematodes, especially in their early stage of major development, that is late (from June onwards), due to the rainy and cold weather conditions.

This was confirmed by analysis of the Plant Protection Service of the Emilia Romagna Region show that the low proportion of adults in the early stages of the production cycle.

The method of application Pochar in the open field was effective and practical in use.
