Plan A
Not a good scenario, infestation increases considerably
Cultivation of fodder radish after spring barley resulted in a further increase in the population, which causes a considerable yield loss in the potato crop in 2010. Although the sugar beet crop in 2011 considerably reduced the population, the cultivation of maize with Perennialy ryegrass resulted in such an increase in the population that the yield loss in the potato crop will also be high in 2013.
