Resistance to soil parasites
This rootstock is fairly tolerant to radicicolae phylloxera but is sensitive to Meloidogyne arenaria and Meloidogyne incognita nematodes. It is somewhat tolerant to  Meloidogyne hapla, Phytophtora cinnamomi and Agrobacterium vitis nematodes.
Adapt to environment
Rupestris du Lot resists up to 25% total limestone, 14% of active limestone and to an CPI of 20. Its resistence to drought is moderate. Avoid planting in soil which is too compact. Slightly tolerant to chlorides and absorbs potassium fairly well. Rupestris du Lot is well adapted to inferior and very little or not limestone soil.
Interaction with grafts and production objectives
Rupestris du Lot easily grows new shoots, but it usually has good affinity with grafts. Good results are found with Grenache N and Ugni blanc B. This root stock vigor is high and induces considerable plant growth. Rupestris du Lot tends to delay vine development and the risk of shot berries with certain sensitive vine varieties may increase.
Aptitudes for plant propagation
Rupestris du Lot internodes are short and its diameter is low to moderate. The wood is hard and the growth of lateral shoots is widespread. Wood production is low (20 000 to 40 000 m/ha) but Rupestris du Lot is good for propagation by cuttings or grafting.
Resistance to aerial parasites
This rootstock is very sensitive to gall mite phylloxera. It is likewise sensitive to anthracnosis but shows high resistance to downy mildew.
