Summary

In Holland the haulm of seed potatoes of many varieties is removed in time to prevent virus infection by aphids. In the last few years pulling the haulm by hand has been partly replaced by killing the haulm with chemicals.

The relative effect of these two methods upon the number of tubers subsequently diseased byPhytophthora infestans has been studied in a field experiment. In the plots where the haulm was pulled by hand, twice as many diseased tubers occurred, as in the plots where it was killed with sodiumarsenite.
