Insecticidal action of mineral-based fertilizers towards Aphis pomi on apple trees

Abstract

The insecticidal activity of novel mineral-based fertilizers by Panamin Asutria towards Aphis pomi was tested. For this purpose, in vitro and in vivo trials were carried out. In vitro tests showed that Panatop Immuno Active and Panatop Immuno Active+ have strong contact insecticidal action at their fertilizer rates of 1 % (v/v), comparable with most commercial synthetic insecticides. As for in vivo trials, no phytotoxic effects were observed during the experiment of the products in all tested varieties of apple trees, even when used at rates tenfold higher than recommended on their labels as fertilizers. Using these types of products can be economical and safe for humans and the environment with low resistance risk towards insects.
