Parasitic roots


Question: Radical parasite


Good morning,
I speak to you because to this day I have not yet succeeded in identifying a parasite that attacks the roots of my plants by eating the roots. Please, could you help me identify it and defeat it? I enclose a photo (macro) of this parasite in his habitat (my vases ...). Its real size (adult specimen) is mm. 2.00 of length x mm.
1.00 wide. The color varies from white to yellow. "More than a rabbit ...".
Your magazine is very interesting and I was wondering if some kind of collaboration is possible (obviously not for the research of this parasite, since after a year and a half of research I have not yet identified it).
I hope you will receive an answer soon and I take this opportunity to offer you
my best regards.

Root parasite: Answer: Radical parasite


Dear Mirella,
Thank you for contacting us about your questions on the root parasite, through the "" expert's column. From the description and the photo sent to us we believe that the parasite of its plants could be Rhizoecus falcifer, the cochineal lives on
roots of different host plants, especially those grown in greenhouses and in pots. When it is present with strong infestations it causes more or less accentuated vegetative deterioration, which on some plants is manifested by the yellowing and drying of the leaves. It multiplies
uninterruptedly with simultaneous presence of the different stages of development. The females lay some dozens of eggs in the middle of a tangle of waxy filaments, from which neanids are born that extend the infestation on the root apparatus of the same plant and to the surrounding ones, on which the insect can develop consistent populations. To avoid the
spread of infestations It is advisable to pot the plants using new soil or sterilized with superheated water vapor. With attacks in place, systemic geodisinfestants can be distributed on the soil of the pots, then providing an irrigation to facilitate the penetration of the preparation at the level of the ardici.
Sincerely.
