    The Heterodera Rostochiensis Woll, is considered the most dangerous potato vermin. In the existent conditions in the Szczecin region the mentioned vermin may become a check to potato exports and to home marketing of seedlings as well. Investigations have shown that the vermin occurs everywhere in the Szczecin region with varied intensity. Most contaminated appear the northern and western districts. It was found that up to the year 1962 4237 farms (with 167 state) farms in the number) were contaminated on an area of 1407 ha. The proportion of contaminated area to the whole potato area made an average of 1,8 %.

    This study aimed at testing and comparing two preparations of the sodium carbohydrate group, the powder "Gamatox" (Owadziak 1,2') and the imported Aldrin in fighting the wireworm. In order to protect potatoes and maize, two years of field and laboratory experiments have been undertaken. The mentioned preparations were either sown into the ground stripewise or used to treat the seedlings and grain. Either preparation produced strong toxic effects on the wireworm, but "Gamatox" acted with more speed and greater power. Aldrin, on the other hand, kept on being toxic till a later time. Stripe sowing into the ground proved more advantageous for the plants than treating the grain or seedlings, the latter way being sometimes detrimental to the germination of the plant seeds.
