ABSTRACT In Ecuador, the principal disease in strawberry is the grey mould caused by B. cinerea. Chemical fungicides are used only for its control but sometime cause phyto-toxicity due frequent application, high doses and non-rotation of active ingredients. The aim of this work was to evaluate the effect of iodinecitrate of cupper (Citrubact) on fruits number afected by B. cinereain Fragaria vesca L. cv. Albion in Tungurahua province. Iodinecitrate reduced the number of infected flowers with B. cinerea. Doses of 0.588 g L^-1 each 14 days; 0.588 g L^-1 each 7 days; 0.392 g L^-1 each 14 days and 0.196 g L^-1 each 7 days of active ingredient increase the number of healthy fruit in comparison with unprotected fruits. Based on results Citrubact is an efficient chemical alternative to control B. cinerea in F. vesca. This fungicide is accepted in strawberry organic production system in Ecuador and other producing countries which conferee added value
