Grafting is a technique that has been known for a long time and is generally used in fruit tree cultivation or for grapevines. This technique most significantly made it possible to survive the great phylloxera epidemic at the end of the 19th century.
With regard to tomato and eggplant, grafting allows for adding vigor and provides the plant with resistance to some diseases. However, some rootstocks have the unfortunate tendency to be too vegetative, meaning they encourage leaf development to the detriment of fruit.
This is why HM.CLAUSE developed a "generative" rootstock, meaning it will combine good development of the plant with good fruit production. This is the PROTECTOR F1 rootstock. It is especially well-suited for use in the garden.
PROTECTOR F1 develops a strong root system that benefits the variety grafted onto this rootstock by providing vigor. The variety grafted onto PROTECTOR F1 will better resist the various stresses of cold, lack of light, or diseases. It will grow equally well in poor soil or if the land is not of good quality or "tired."
The resistances provided by the PROTECTOR F1 rootstock are:
- an intermediate resistance (that is, partial) to some nematodes present in the soil
- greater resistance to the tomato mosaic virus and to diseases caused by pathogenic fungi such as verticillium, tomato fusarium or tomato vascular fusarium (races 1, 2 and 3)
