May is the time for planting potatoes. The most dangerous enemy of the second bread is the nematode. A potato nematode is a worm of microscopic size that lives in the root system of a potato plant and causes its inhibition.
At the same time, the plants lag behind in growth, the leaves turn yellow, no more than 1-3 stems are formed, a mass of small roots is formed (there is a “beard” of the root system), tubers are formed in the size of 15-45 grams, with a strong lesion, tubers do not form under the bush.
Golden potato nematode is a dangerous quarantine pest. The potato nematode is more often distributed in household plots where potatoes are cultivated as a monoculture (only potatoes are grown).
During phytosanitary surveys on the territory of the Ulyanovsk region by the territorial administration of the Rosselkhoznadzor on previously identified foci, a nematode was confirmed in household plots in 14 districts of the region, including Bazarnosyzgansky, Baryshsky, Veshkaimsky, Mainsky, Karsunsky, Sengileevsky, Sursky, Inzensky, Tsilninsky, Tergulinsky Novospassky, Kuzovatovsky, Staromainsky.
In accordance with this, experts of the Rosselkhoznadzor warn that quarantine phytosanitary measures must be observed: products grown in the quarantine phytosanitary zone must undergo a quarantine phytosanitary condition with mandatory registration of a quarantine document (phytosanitary control certificate, quarantine certificate); the movement of soil from foci is prohibited; it is necessary to immediately clean the tillage implements, equipment and warehouses; use nematoderesistant varieties of potatoes for planting; use crops that are not affected by the nematode in the crop rotation; apply organic mineral fertilizers.
Potatoes should return to their original place no earlier than 4 years later (depending on the degree of infection), in these intervals it is recommended to sow other crops.
Given the harmfulness of this quarantine organism and the safety of cysts for more than 10 years, citizens need to be conscious and responsible when cultivating potatoes in their home gardens in order to prevent the spread of golden potato nematodes.
