"Ditylenchus destructor" can reproduce at high rates and cause large amounts of damage to hosts and so can be very damaging to a cash crop. One of the most important impacts of "Ditylenchus destructor" is in South Africa, where it caused major disease amongst the peanut plantations in the early 1990s. In fields where the nematodes have been found, between 40% and 60% of the peanuts had large amounts of symptoms which heavily damaged the production levels. Similarly, the same issues were observed in Sweden in the 1970s when "Ditylenchus destructor" was found in their potato fields. In this instance it caused disease in between 40% and 70% of the potatoes being grown in the field where the pathogen was found. Finally, one of the more severe cases of the disease was found in Estonia in the 1960s. In this case the nematodes were only found on about 6% of the potato farms but on these farms between 70% and 90% of the potatoes exhibited severe symptoms. This high rate of disease caused immense damage to the fields that were infected and a large amount of crops were lost.
