abstract:
Observations on aphid occurrence were carried out on broad beans (Vicia faba L. ssp. maior), White Windsor c.v. The experiment was conducted to learn how magnesium treatment and magnesium fertilization coupled with liming of soil with elevated heavy metal concentrations (1st class of pollution according to ISSPC classification) affect the occurrence and dynamics of plant viral disease vector, i.e., Aphis fabae Scop. Magnesium treatment carried out on heavy metal contaminated soil influenced a decrease in cadmium and nickel contents in pods and enhanced liming activity in limiting lead, nickel and cadmium uptake by broad bean roots and zinc by roots and some above-ground parts. Magnesium fertilization of heavy metal contaminated soil contributed to lowering the numbers of A. fabae aphids during the period of its most intensive occurrence. Broad bean plants grown in heavy metal contaminated soil were less settled by the pest when magnesium treatment and liming were applied.
