Efikasnost fungicida u suzbijanju prouzrokovača plamenjače paradajza (Phytophthora infestans (Mont.) de Bary) u uslovima jake pojave oboljenja
Efficacy of fungicides in control of tomato late blight (Phytophthora infestans (Mont.) de Bary) under conditions of heavy disease incidence
Sažetak
U toku 2020. godine, vršeno je ispitivanje biološke efikasnosti fungicida propamokarb - hidrohlorid + fluopikolid, cimoksanil, mandipropamid + difenokonazol i dimetomorf + mankozeb u suzbijanju prouzrokovača plamenjače (Phytophthora infestans) u usevu paradajza. Ogledi su izvedeni na lokalitetima Sovljak (Ub), Belosavci (Topola) i Garaši (Aranđelovac), po tipu potpuno slučajnog blok sistema u četiri ponavljanja (EPPO, 1996). Na svakom lokalitetu izvršeno je po pet tretiranja, a ocene efekata vršene su u dva navrata. Povoljni agrometeorološki uslovi rezultirali su značajnom pojavom oboljenja u kontroli, koja je iznosila 17,5-41,3% u prvoj, odnosno, 28,8-95,0% u vreme druge ocene efekata. Primenom kombinacije fungicida propamokarb-hidrohlorid+fl uopikolid ostvarena je efikasnost u iznosu od 94,5-99,4% u prvoj, odnosno, 92,3-97,9% u drugoj oceni. Cimoksanil je ispoljio efikasnost koja je iznosila 83,0-92,9% u prvoj, i 80,0-89,5% u drugoj oceni. Kombinacijom fungicida mandipropamid+difenokonazol postignuta je efikasnost od 89,1 do 99,7% u prvoj, odnosno 88,2-98,5% u vreme druge ocene efekata. Sa kombinacijom fungicida dimetomorf+mankozeb ostvarena efikasnost iznosila je 94,1-97,8% u prvoj, odnosno 90,7-97,7% u drugoj oceni.
Abstract
During the season 2020, the biological efficacy of fungicides propamocarb hydrochloride + fluopicolide, cymoxanil, mandipropamide + difenoconazole and dimothomorph + mancozeb in the control of late blight (Phytophthora infestans) in tomato, was investigated. The experiments were conducted in the localities of Sovljak (Ub), Belosavci (Topola) and Garaši (Aranđelovac). The experiments were carried out as a randomized block system in four replication (EPPO, 1996). A total of five treatments and two assessments were performed at each location. Favorable conditions resulted in a significant disease intensity on untreated plots, which amounted from 17,5-41,3% in the first, and 28,8-95,0% during the second assessment. Fungicide mixture propamocarb-hydrochloride+fluopicolide, showed the efficacy from 94,5-99,4% at the first, and 92,3-97,9% at the second assessment. Fungicide cymoxanil, showed the efficacy of 83,0-92,9% at the first, and 80,0-89,5% at the second assessment. Fungicide mixture mandipropamide+difenoconazole achieved the efficacy from 89,1-99,7% at the first, and 88,2-98,5% during the second assessment. By a combination of dimothomorph+mancozeb the efficacy was ranged from 94,1-97,8% at the first and from 90,7-97,7% at the second assessment.
