Osetljivost Monilinia laxa (Ader. & Ruhl.) na fungicide razliÄitog mehanizma delovanja
Sensitivity of five M. laxa isolates from mumified plum fruits was tested to benomyl,
iprodione, trifloxystrobin, tebuconazole and pyrimethanil. Mycellia growth inhibition on
growth medium was monitored and susceptibility parameters were determined using probit
analysis. The EC50 values for benomyl were the highest, ranging from 123.1 to 901.5 ÎŒg/kg, followed by iprodione (125.9-301.4 ÎŒg/kg), trifloxystrobin (4.2-9.2 ÎŒg/kg), tebuconazole
(14.2-41.8 ÎŒg/kg) and pyrimethanil (148.0-190.8 ÎŒg/kg). Natural M.laxa populations medium
resistant to benomyl were established. The isolates tested showed a normal sensitivity to
iprodione, trifloxystrobin, tebuconazole and pyrimethanil.Ispitivana je osetljivost pet izolata M. laxa izolovanih sa mumificiranih plodova ĆĄljive
na benomil, iprodion, trifloksistrobin, tebukonazol
i pirimetanil. PraÄena je inhibicija porasta micelije
na hranljivoj podlozi i utvrÄeni su parametri osetljivosti metodom probit analize. NajveÄi raspon
srednjih efektivnih koncentracija bio je kod benomila (123,1-901,5 ÎŒg/kg). EC50 vrednosti
za ostale fungicide bile su u intervalu: iprodion
(125,9-301,4 ÎŒg/kg)), trifloksistrobin (4,2-9,2 ÎŒg/kg)), tebukonazol (14,2-41,8 ÎŒg/kg)) i pirimetanil (148,0-190,8 ÎŒg/kg). UtvrÄeno je
postojanje umereno rezistentnih prirodnih
populacija M. laxa na benomil. Svi ispitivani
izolati ispoljili su normalnu osetljivost na iprodion,
trifloksistrobin, tebukonazol i pirimetanil
Efikasnost biofungicida Polyversumâą u suzbijanju Botrytis cinerea Pers. na plodovima maline
Efficacy of a biological fungicide product, Polyversumâą (Pythium oligandrum Drechsler),
in controlling grey mould of raspberries Botrytis cinerea Pers. was tested at sites around
Valjevo, PoĆŸega and Ć abac in 2004, 2005 and 2006. The experiments were conducted and
data processed using EPPO methods.
Efficacy was found to be significantly lower statistically in the experimental variants
involving Polyversumâą biofungicide (E = 18.0%-53.9%) than the standard botricide Ronilan-
DF (E = 56.6%-90.3%).
Our results show that the biological product Polyversumâą achieved significant efficacy
although poorer than the standard fungicide Ronilan-DF. As it is a biological product
almost entirely free of any toxicological and ecotoxicological limitations, it offers a significant
advantage for widespread usage in plant protection.U toku 2004, 2005. i 2006. godine, na lokalitetima
Valjeva, PoĆŸege i Ć apca, ispitivana je efikasnost
bioloĆĄkog preparata Polyversum âą (Pythium
oligandrum Drechsler) u suzbijanju prouzrokovaÄa
sive truleĆŸi plodova maline Botrytis cinerea
Pers. Eksperimenti su izvedeni i podaci obraÄeni
po metodama EPPO. UtvrÄeno je da je u varijantama primene biofungicida Polyversum
âą efikasnost (E=18.0%- 53.9%) statistiÄki znaÄajno slabija od standardnog botriticida
Ronilan- DF (E=56.6%-90.3%). Ispoljena
efikasnost bioloĆĄkog preparata Polyversum
je znaÄajna, iako slabija od standardnog
fungicida Ronilan- DF. S obzirom da je reÄ o bioloĆĄkom preparatu koji gotovo da nema
toksikoloĆĄkih i ekotoksikoloĆĄkih ograniÄenja,
to mu daje znaÄajnu prednost za ĆĄiru

Efikasnost kombinacija nespecifiÄnih i fungicida iz grupe strobilurina u suzbijanju ÄaÄave pegavosti jabuke
The efficacy of several fungicide mixtures in controlling Venturia inaequalis in apple was
evaluated in field trials. The efficacies of Flint Plus (trifloxystrobin + captan) and Tercel (pyraclostrobin
+ dithianon) in comparison with standard fungicides Zato 50-WG (trifloxystrobin)
and Stroby + Delan (kresoxim-methyl + dithianon) were tested in the localities Mihajlovac,
Radmilovac and Landol in 2004 and 2005. Both tested fungicides exhibited high efficacy
in controlling apple scab. There were significant differencies in the efficacies of Flint Plus
(91.3-98.5%) and Zato 50-WG (68.2% and 78.4%); and Tercel (88.7-93.5%) and Stroby + Delan
(77.9% and 82.1%). Our experiments showed that the investigated fungicide mixtures are
highly effective against V. inaqeulais, even under high disease pressure.Ispitivana je efikasnost nekoliko kombinacija fungicida u suzbijanju Venturia inaequalis
na jabuci u poljskim uslovima. U 2005-oj i 2006-oj godini ispitivana je efikasnost Flint Plus
(trifloksistrobin + kaptan) i Tercel (piraklostrobin + ditianon) u odnosu na standardne fungicide
Zato 50-WG (trifloksistrobin) i Stroby + Delan (kresoksim-methil + ditianon) na lokalitetima
Mihajlovac, Radmilovac i Landol. Oba ispitivana fungicida ispoljila su visoku efikasnost
u suzbijanju ÄaÄave pagavosti jabuke. IzmeÄu efikasnosti Flint Plus (91.3-98.5%) i Zato
50-WG (68.2% i 78.4%), i Tercel (88.7-93.5%) i kombinacije fungicida Stroby + Delan (77.9% i
82.1%) zabeleĆŸena je statistiÄki znaÄajna razlika. NaĆĄi ogledi su pokazali da su ispitivane kombinacije
fungicida visoko efikasne protiv V. inaequalis Äak i u uslovima jake zaraze
Efikasnost mandipropamida za suzbijanje prouzrokovaÄa plamenjaÄe krompira u poljskim uslovima
The efficacy of mandipropamid (Revus 250 SC) in controlling Phytophthora infestans
in potato was evaluated in field trials. The efficacies of Revus 250 SC in comparison with
standard fungicides Quadris (azoxystrobin) were tested in several localities in Serbia
(Kasarske Livade, Valjevska Kamenica and Opovo) in 2007 and 2008. Both of the tested fungicides
exhibited high efficacy in controlling potato late blight. The differencies in the efficacy
of Revus 250 SC (96.3- 99.2%) and Quadris (94.1-95.5%) were insignificant. Our experiments
showed that the investigated fungicide was highly effective against P. infestans even
under high disease pressure.Ispitivana je efikasnost mandipropamida (Revus 250 SC) za suzbijanje Phytophthora infestans
u usevu krompira u poljskim uslovima. Efikasnost preparata Revus 250 SC ispitivana je na nekoliko
lokaliteta u Srbiji (Kasarske Livade, Valjevska Kamenica i Opovo) tokom 2007. i 2008. godine.
Kao standard posluĆŸio je Quadris (azoksistrobin). Oba ispitivana fungicida su ispoljila visoku
efikasnost u suzbijanju prouzrokovaÄa plamenjaÄe krompira. IzmeÄu efikasnosti Revus 250 SC
(96.3- 99.2%) i Quadris (94.1-95.5%) nije utvrÄena statistiÄki znaÄajna razlika. NaĆĄi ogledi su pokazali
da je ispitivani fungicid visokoefikasan u suzbijanju P. Infestans, Äak i u uslovima jake zaraze
Estimation of Parameters Obtained by Electrochemical Impedance Spectroscopy on Systems Containing High Capacities
Electrochemical systems with high capacities demand devices for electrochemical impedance spectroscopy (EIS) with ultra-low frequencies (in order of mHz), that are almost impossible to accomplish with analogue techniques, but this becomes possible by using a computer technique and accompanying digital equipment. Recently, an original software and hardware for electrochemical measurements, intended for electrochemical systems exhibiting high capacities, such as supercapacitors, has been developed. One of the included methods is EIS. In this paper, the method of calculation of circuit parameters from an EIS curve is described. The results of testing on a physical model of an electrochemical system, constructed of known elements (including a 1.6 F capacitor) in a defined arrangement, proved the validity of the system and the method
