Summary Comments
Main rootstock used in California because it is resistant to root-knot nematode and is compatible with peach, nectarine and plum. It makes a vigorous, productive tree with good fruit size. However, it does not tolerate waterlogged or calcareous soils and is susceptible to many soil pests including ring nematode, bacterial canker and armillaria. |
