| Abstract:
In three vineyards of 'Condado de Huelva' with Grapevine fanleaf virus (GFLV) infected plants and vector nematodes Xiphinema index and X. Italiae, the Plant Disease Progress Curve (PDPC) was determined. The Logistic and Gompertz models indicate that the vineyards will become totally infected in 25-42 years. The agroecological factors that affect the life of the vectors are considered decisive for the infection rate evolution of each vineyard. | |
