Cooke LR, Little G: The effect of foliar application of phosphonate formulations on the susceptibility of potato tubers to late blight. Pest Manag Sci. 2002 Jan;58(1):17-25.
In contrast, foliar application of fosetyl-aluminium did not significantly reduce tuber blight development following inoculation. In trials where the effect of timing and rate of application of 2-4 kg phosphonic acid ha-1 was examined, a single treatment of 4 kg ha-1 applied mid- or late-season proved the most effective. |
