Experiments on potato-tuber treatment in order to control mealy bug (Pseudococcus) infestations, are briefly described. Dust applications of "Rhodiatox0,50%" at the rate of 300 g per 70 kg of potato tubers, have been effective against these pests. In this case tubers cannot be used for human consumption. Methyl bromide at the rate of 150 cc per 28,6 m3 in vacuum chamber, during six hours, killed the insects and did not damage tuber sprouting. In this case, tubers can be used for seeds and consumption. This treatment does not prevent another infestation, as does that with "Rhodiatox".
