Project: Tomato grafting mitigates biotic stress caused by whiteflies (TomGraf; IP-2014-09-3365)

The aim - We expect that selection of rootstock/s can be used as a useful tool in management strategy against whiteflies ensuring the satisfactory effect on yield and fruit quality components.

RESULTS I The effect of tomato rootstock on adult density of B. tabaci

B. tabaci adult population density was lower on grafted tomatoes

compared to non-grafted or self-grafted tomatoes (three sampling).

SLIDE 15

RESULTS II The effect of tomato rootstock on adult density of T. vaporariorum

Number of T. vaporariorum adult individuals per leaf was lower on tomato plants grafted onto the rootstock Buffon compared to non-grafted or self- grafted tomatoes (three samplings).

SLIDE 16

CONCLUSION

The results can be applied in an integrated protection against B. tabaci and T. vaporariorum
