The root - knot nematode Meloidogyne enterolobii can spread through ebbing - and - flow water , as confirm by research lead by Wageningen University & Research ( WUR ) . pollution can occur when the body of water comes into contact with industrial plant infected by these nematodes . therefore , ebb - and - menstruum irrigation systems stupefy a risk for the spread of M. enterolobii . WUR conducted research on behalf of the NVWA into the transmission of these nematodes from infected plants to ebb - and - flow H2O , which initially interacts with works and potting soil before being drained by .

Meloidogyne enterolobii , a tropical root - nautical mile nematode not aboriginal to the Netherlands , has been consistently detected in imported pile of potted plants in late year . This presents a risk of usher in septic plants into Dutch soil , with all its tie in upshot . These minute organisms can cause pregnant ( economical ) damage to various crops , including tomatoes , peppers , cuke , and potatoes . Research on Meloidogyne enterolobii nematode worm in ebb - and - flow waterPrevious studies had already show that Meloidogyne nematodes could fan out through irrigation water . It had also been demonstrated for various root parasite , such as M. incognita , that they could spread through reflux - and - flow systems . Therefore , spread in reflux - and - period systems seemed possible for M. enterolobii as well . However , the extent to which this would come remained uncertain .

plan and result of the studyWUR conducted a greenhouse trial with two boniface plants : tomato ( Solanum genus Lycopersicum cv . ' Dometica ' ) and bonsais of the Nipponese elm ( Zelkova serrata ) . For the subject area , WUR used artificially taint love apple plants and Zelkova bonsais from an intercepted import batch .

The plants were placed in ebbing - and - stream trays ( one plant per tray ) , and over a period of eight week , an ebb - and - flow handling ( tearing ) was applied once a week . Subsequently , the ebb - and - menstruation urine was collected and concentrated . WUR counted the number of M. enterolobii nematode worm in this saturated solution .

In the ebb - and - flowing water supply from more than one-half of the tomato plants and all of the Zelkova bonsais with symptom , M. enterolobii nematodes were found . This demonstrates that M. enterolobii nematodes can drain out of the pot in an reflux - and - period irrigation system , thus contaminating the ebb - and - catamenia water .

required measures against root - knot nematodesSince April 11 , 2022 , EU member United States Department of State have been required to follow out measurement to prevent the introduction of these nematodes . Like other EU fellow member states , the Netherlands must eradicate the organism if chance to keep further spread .

It is also crucial for enterpriser to take necessary measures to prevent contamination and counterpane . One can inquire about robust guarantees from the supplier . Moreover , it is important to physically separate the plants from other peck for at least ten weeks after import . Additionally , regularly checking the roots for nodule symptoms is send word . Ensure that the irrigation systems are kept freestanding and that water is effectively disinfected through methods such as heating , ultraviolet light treatment , or ultrafiltration .

sustain detailed records is essential . Additionally , it is of import to label the plants in a style that permit for sluttish note between different pot . Finally , data on recognizing an infection with root - air mile nematodescan be found here .
