Abstract:The grapevine canopy changes a lot along the growth season, so do the application rates. Three models were used with the aim to apply pesticides on grapevine rationally. The models mentioned were unit canopy row (UCR), leaf wall area (LWA), and DOSAVIA. The results showed that at early growth stage, the deposits for DOSAVIA, LWA and traditional method were not different significantly, neither for UCR, DOSAVIA and LWA; at middle growth stage, LWA method achieved the similar deposits to traditional, UCR got the minimum deposits; at the late growth stage, the traditional method had the maximum deposits than the others. Among all the trials at three growth stages, the distributions of deposits (CV)were very closed to each other.
