To control grape fanleaf nepovirus, which practice is NOT recommended?

Fumigation is an important practice in controlling grape fanleaf nepovirus because it targets nematodes, which are the primary vectors for the virus. Ignoring fumigation may allow these pests to thrive and perpetuate the virus's presence in the vineyard. Effective control strategies often include practices such as using nematode-free stock, implementing long non-host rotation, and utilizing resistant rootstock—all aimed at reducing pathogen load and preventing infection. By actively engaging in practices that mitigate nematode populations, growers can better protect their grapevines from grape fanleaf nepovirus. Therefore, overlooking fumigation is detrimental to managing this plant pathogen effectively.
