Salicylic acid mediates resistance in the willow Salix viminalis against the gall midge Dasineura marginemtorquens.

abstract：:Simple inorganic salts of the ions K(+), NH 4 (+) , Cs(+), NO 3 (-) , and Cl(-) are strongly repellent to infective second-stage larvae of the root knot nematode,Meloidogyne incognita. Some of these salts are known to be beneficial to plant growth. The results suggest a new means of plant protection. ...
