Control of root knot nematodes (Meloidogyne spp.) in carrot

Cilj ovog istraživanja bio je utvrditi koje su najpovoljnije mjere zaštite od nematoda korijenovih kvržica, roda Meloidogyne. Pokus je postavljen na parceli u Detkovcu, na mjestu gdje je tjedan dana prije bila izvađena mrkva, na pjeskovitom tlu. Pokus je postavljen po slučajnom blok rasporedu, u tri tretmana (kontrola, Velum Prime i Basamid granulat), te 5 ponavljanja. Provedeni pokus je pokazao kako postoje statistički značajne razlike između primijenjenih nematocida Velum Prime, kontrole, te preparata Basamid granulat i tretman kontrole. Statistički značajne razlike u brojnosti nisu uočene između tretmana s preparatom Velum Prime i preparata Basamid granulat. Dobiveni rezultati pokazuju kako je brojnost nematoda u uzorku od 50 g tla, u drugom i trećem uzorkovanju smanjenja s obzirom na prvo uzorkovanje u oba tretmana s primjenjenim kemijskim pripravcima, dok u kontrolnom tretmanu statističke razlike u sva tri vremena uzorkovanja nisu utvrđene. Iako su preparati na bazi fluopirama (Velum Prime) i dazometa (Basamid granulat) pokazali statistički značajno smanjenje nematoda korijenovih kvržica u tlu, još uvijek su brojnosti preživjelih nematoda bile visoke, te bi najvjerojatnije predstavljale problem u budućoj proizvodnji povrća na tim parcelama.The aim of this investigation was to determine the most favorable measures for protection against root knot nematodes, Meloidogyne, spp. The experiment was set up in Detkovac, where a carrot was removed a week ago, on sandy soil. The experiment was set up by random blockdesign, in three treatments (control, Velum Prime and Basamid granulate), and 5 repetitions. The experiment showed that statistically significant differences between total number of Meloidogyne, at the end of experimental period occured betven treatment V nad K, as well as between teratment B and K. Statistically significant differences wasn't occured between treatment with Velum Prime and Basamid granulate preparations. Obtained results showed significant reduction of Meloidogyne in second and third sampling in compare to the first sampling in both treatments with the applied chemistry preparations, while in control treatment significant decrease in number of in all three sampling periods not occured. Although investigated preparation (V and B) shoved reduction of root knot nematodes in compare to control treatment, the numbers of survival nematodes (Meloidogyne) still remained high and would most likely pose a problem in future vegetable production on these plots
