The chemical defoliation of Ligitstrum vulgare L. and Spiraea x arguta Zab. shrubs in nursery

To defoliate Ligustrum vulgare and Spiraea x arguta – ethephon, KJ, Mg(ClO3)2•6H2O, CuSO4•5H2O and (NH4)2SO4 in various concentrations were used alone or in mixtures. Treating plants with potassium iodide gave the best results. KJ concentrations of 0.05-0,1% and 0.1-0.% were sufficient to defoliate...

Magnesium chlorate at concentration of 0.24 and 2% CuSO4 were also effective, the latter however, proved slight harmful to the plants. Spraying with defoliants on Sept. 26 gave better results than treating plants on Sept. 16. Chemical defoliation decreased negligibly the frost resistance of Ligusturm vulgare shrubs.https://pbsociety.org.pl/journals/index.php/aa/article/view/5992
