Botrytis:

Goeie bedekking van die strukturele dele van die tros baie belangrik.

Botrytis moet voorkomend beheer word vanaf die blomstadium. Die belangrikste spuitstadiums is:

Blom - baie belangrik
Ertjiekorrel - baie belangrik
Deurslaan - belangrik indien toestande gunstig is vir die ontwikkeling van die siekte
Kort voor oes - belangrik in tafeldruiwe

Goeie landboupraktyke met betrekking tot sanitasie (ook snoeisels), bemesting, besproeiing, loofbestuur speel `n baie belangrike rol in beheer van Botrytis.

Prodione 500 SC - by deurslaan en net voor oes (indien nodig)
