Efikasnost različitih fungicida u suzbijanju prouzrokovača plamenjače spanaća

Abstract

Prouzrokovač plamenjače spanaća u proizvodnji nanosi značajne štete, smanjujući upotrebnu vrednost listova. S obzirom da u R. Srbiji nema registrovanih fungicida za suzbijanje plamenjače na spanaću, cilj istraživanja je bio ispitivanje efikasnosti različitih fungicida za preventivnu i terapeutsku primenu. U istraživanje je uključeno sedam sintetičkih i jedan biološki fungicid. Najniži intenzitet zaraze u preventivnom (0,10%) i terapeutskom (0,33%) tretmanu utvrđen je kod primene kombinacije aktivnih supstanci famoksadon + cimoksanil. Međutim, kod odabira i primene fungicida u spanaću posebna pažnja se mora posvetiti karenci formulisanog preparata.

Powdery mildew of spinach cause significant damage in agriculture production reducing the value usage of the leaves. Considering that there are no registered fungicides for controlling the powdery mildew of spinach in the Republic of Serbia, the aim of the research was to examine various fungicides for preventive and therapeutic usage. The study included seven synthetic and one biological fungicide. The lowest intensity of infection in preventive (0.10%) and therapeutic (0.33%) treatment was found when using a combination of active substances famoxadone + cimoxanil. However, when choosing and applying fungicides in spinach, special attention must be dedicate to the withdrawal period of the formulated products.
