Authors: Radivojevic Stevan , Dosenovic Irena , Kabic Dragica , Gyura Julianna , Rozic Ratko , Sabados Vladimir
Published: May 2023

Sugar beet field trials were planted in 2004 in order to determine sugar and root yield and the quality of sugar beet varieties depending on varietal tolerance to Rhizomania. The field trials were located at the agricultural station in Kikinda, covering a highly infested area and at the "Agroinstitut" in Sombor, where no infestation had been reported. At both locations twenty-one sugar beet varieties were planted. The selected varieties were provided from breeders distributing new selections in Serbia. At Kikinda beet root yield was 85.78 t/ha for Concerto variety and 12.00 t/ha for control variety (intolerant to disease). The obtained difference amounts to 73.78 t/ha or 86.01%. Difference in sugar content within the first-ranked variety Ivona (15.36%) and the control sample (10.91%) was 4.45% absolute. But, the established difference for crystalline sugar yield between the first-ranked variety Remos (9.205 t/ha) and the control variety (0.842 t/ha) amounted to 8.363 t/ha or 90.85%. At the other location, Sombor, extreme differences within varieties were also observed but to a lesser extent.

Published: May 2023

Sugar beet root rot appears regularly each year, but its intensity depends on agro ecological conditions. The predominant causers of root rot in Vojvodina are fungi from Fusarium genus and species Macrophomina phaseolina. Over the last couple of years, more intense occurrence of Rhizoctonia root rot has been observed. Rhizoctonia solani, the causal agent of root rot is present in sugar beet fields. During 2000-2005, on the territory of Vojvodina, the frequency of Rhizoctonia solani in phytopathological isolations from rotted sugar beet roots was between 0,0-18,2%. The intensity of the disease depends on localities, agro ecological conditions and genotypes. Symptoms of Rhizoctonia root rot were registered at some localities in all regions of Vojvodina: Srem, Banat and Backa. The disease appearance is above all local. It occurs in small patches, on heavy, non-structured soil and on depressed wet parts of plots. Individual diseased plants can be found during July. Brown rot appears on sugar beet roots, with dried tissue on surface, which is present on the tail as well as on the middle part and the head of root. Tissues with described symptoms are deeper regarding the healthy part of root. On vertical root section, the necrotic changes are clearly visible comparing to tissue section without symptoms. The heavily infected tissue forms fissures on roots in most cases. Besides the above-mentioned symptoms on roots, the plant wilting and leaf handle necrosis as well as leaf dying are also observed. When rot spreads to the whole root head, plants quickly die.

Published: May 2023

The aim of this work was to study the effect of sugar beet re-growth after water stress defoliation on root rots of three cultivars (Europa, Rival Corsica), which were spring sown in Thessaly, central Greece, for two growing seasons (2003-04). At the beginning of July, sugar beets were subjected to water deficit with irrigation withholding. A month later, three defoliation levels (control - C, moderate - MD, severe - SD) and irrigation were applied. Thus, sugar beets were forced to re-grow and three harvests (15, 30 and 40 days after defoliation - DAD) were conducted. Rotted roots per hectare were counted and pathogens were identified. Data were analyzed as a four-factor randomized complete block design with years, defoliation levels, sampling times and cultivars as main factors. The number of rotted roots was increased with the defoliation level and was significantly higher for SD sugar beets (3748 roots ha?1). No significant differences were found between C and MD treatments (1543 and 2116 roots ha?1, respectively). Rival was the most susceptible cultivar to root rots. Sugar beets were more susceptible to rotting 15 and 40 DAD (2778 and 2998 roots ha?1). The causal agents of root rots were the fungi, Fusarium spp., Rhizopus stolonifer, Macrophomina phaseolina and Rhizoctonia solani.

Authors: Karaoglanidis George , Karadimos Dimitros
Published: May 2023

Powdery mildew, caused by Erysiphe betae is a major foliar disease of sugar beet in areas with dry and relatively warm weather conditions throughout the world. In the present study, four fungicides belonging to the relatively new class of strobilurin fungicides, azoxystrobin, kresoxim-methyl pyraclostrobin and trifloxystrobin were evaluated in three different application doses (100, 150 and 200 mg a.i. ha?1) during 2003-2004 for the control of the disease. Among the four strobilurin fungicides tested trifloxystrobin and kresoxim-methyl were the most effective with control efficiency values higher than 94% compared to the control treatment even when applied at lower application dose of 100 mg a.i. ha?1. Azoxystrobin and pyraclostrobin showed a poor to modest activity against the disease even when applied at the highest application dose of 200 ?g a.i. ha?1. Disease severity, in terms of AUDPC values was significantly correlated to decreased root yield, while no significant correlation existed among disease severity and sugar content of the roots or sucrose yield. In addition, the efficiency of tank mixtures of four strobilurin fungicides applied at 100 ?g a.i. ha?1 with two sterol demethylation - inhibiting fungicides (DMIs), difenoconazole and cyproconazole applied at 62.5 and 25 mg a.i. ha?1, respectively, was evaluated. The mixtures of azoxystrobin and pyraclostrobin with either difenoconazole or cyproconazole provided a better control efficiency compared to the single application of each mixture partner, while the tank mixtures of trifloxystrobin and kresoxim-methyl with either difenoconazole or cyproconazole provided a better control efficiency compared to single application of difenoconazole or cyproconazole and similar control efficiency compared to the efficiency obtained by single application of the strobilurin fungicides.
High risk pesticides in sugar beet protection
Authors: Sovljanski Radmila , Klokocar-Smit Zlata , Indjic Dusanka
Published: May 2023

According to traits of pesticides permitted to use in sugar beet (oral percutaneus and inhalation toxicity, toxicity to wildlife, bees and aquatic organisms, re-entry interval, maximum number of treatments, effects on reproduction) do not present health risk in sugar production/technology. However, the danger exists for workers by chronic exposure during the application, especially from pesticide being potential endocrine disruptors (EDS) (fentin acetate, benomyl, endosulfan, methomyl, methidathion). EDS can cause sterility or decreased fertility, impaired development, birth defects of the reproductive tract and metabolic disorders. Authors recommend limited application of EDS pesticides (to limit the number of treatments to only one during the vegetation), replacement with pesticides with low risk to humans game and fishes, as well as mandatory submission of re-entry data for registration.

Published: May 2023

The effects of insecticides monocrotophos, cypermethrin and their ready -made mixtures applied against sugar beet root weevil (B. punctiventris G e r m) adults at different temperatures were studied. The experiments were conducted in laboratory conditions at three different temperatures: 14, 20 and 25?C. In 1996 and 1997, the adults used in experiments were collected in Backa Topola fields with sugar beet as previous crop. The adults were exposed to insecticides by method of insecticide soaked blotting paper and fed with sugar beet cotyledons. The mortality of adults, depending on product was observed every half an hour, starting from 0.5 up to 28 hrs of exposition. Applying probit analyses, ld-p and lt-p lines were constructed, which reflected the changes of toxity depending on insecticides and temperatures. According to position and slope (b) of ld-p lines in 1996, higher toxity of cypermethrin than of monocrotophos was found. The response was more homogeneous to cypermethrin than to monocrotophos. Ld-p lines for mixture run closer to ld-p line for cypermethrin independent of temperature. In 1997, at 14?C and 25?C, higher toxity of cypermethrin than of monocrotophos was observed, the effect of mixture was additive. No mortality was induced with monocrotophos at 20?C. The reason could be in sugar beet root weevil population sensitivity decrease to monocrotophos in 1997, or the insects derived from two different populations exposed to different selection pressure (species, volume and exposition length to insecticides). Based on lt-p lines in both experimental years, it could be concluded that cypermethrin, independent of temperature had higher initial toxity than monocrotophos, the mixture achieved additive effect, except in 1996 at 20?C where the effect was synergised compared to single component effects.

Authors: Puskas János , Nowinszky László , Makra László
Published: May 2023

The light-trap collecting results, showing its flight activity, of turnip moth (Scotia segetum S c h i f f) was examined connected with meteorological events. These factors were instability line, the convergence zone, the cyclogenesis, the country-wide rain, the cold- and warm weather fronts, the maritime- and continental moderate, arctic and subtropical air masses used the data published in "Calendar of Weather Phenomena" between 1967 and 1990 by National Meteorological Service. There were 29832 moths caught during 3232 night by 64 light-trap stations in the examined period. During one night more light-traps operated, therefore 25.021 observing data were worked up. We mean that the observing data are the same as the catching data at one night, at one observing station. The data of meteorological events were collected into groups according to their occurrence on one day alone or together with other ones. They were collected into separated groups according to arriving after a day without any meteorological events or if there were any of them on the previous day. The values of relative catch (RC) were calculated daily for each observing stations and generations used the catching data. There was made a comparison between the relative catch (RC) values and the meteorological events belonging to the data and on previous and following days. Then the relative catch values were summarized and averaged daily. The differences of daily average values of significance levels were controlled with t-test in all the groups. More than 95% significance levels were found in 36 groups. The favourable and infavourable influences of each event are the strongest at that time, when have influence not only alone but also with other effects simultaneously or they follow one another in a short time. Our results prove clearly, it is not enough to examine exclusively the modifying influence of each meteorological event on light-trap collecting. The success of light trapping is modified depending on several combinations of each meteorological event and they are not very often the same as the catching result of event to have an influence only.

Published: May 2023

The overall patterns of correlations among various melanoma risk factors have not yet been examined. The aim of this study was to assess the impact of different parameters on disease-free and melanoma-related overall survival. A retrospective cohort study was conducted encompassing all patients with a primary cutaneous melanoma diagnosed in a university referral centre. Associations were explored using semantic map analysis, which uses graph theory to find the strongest path of connections between variables. A total of 1,110 melanoma patients (median follow-up 10.6 years) were included. The analysis revealed a clustering of variables around 2 main hubs: Breslow thickness < 1 mm and ≥ 4 mm. Factors connected with high melanoma thickness were: older age, positive sentinel lymph node biopsy findings, presence of ulceration, nodular melanoma type, and light skin phototype. Both disease-free and melanoma-related overall survival were in this cluster and connected with positive sentinel lymph node biopsy and Breslow ≥ 4 mm. Patients with Breslow between 1 and 3.9 mm were also in this cluster and linked with negative sentinel lymph node biopsy, nodular melanoma and safety distance > 10 mm. This semantic analysis confirmed the close link between Breslow thickness, age, sentinel lymph node biopsy findings, skin type, melanoma subtype and prognosis, and provides prognostic information useful for the further stratification and management of patients with melanoma.

The study entitled Women's Language Features on Utterances of Charlie's Angels Movie seeks to examine women's language features and the reasons of using the features by the three main women character. The data was taken from the utterances of the Charlie's Angels (2019) movie. The researchers used Lakoff's hypothesis to investigate women's language features. Lakoff (1975) suggested ten language features for women, but this analysis only found nine features in this movie, namely lexical hedges or fillers, intensifiers, tag question, emphatic stress, rising intonation on declaratives, avoidance of strong swear words, super polite forms, empty adjectives, and hypercorrect grammar. The findings indicated that intensifiers appeared to be the most prominent attribute utilized among the three main women’s characters in the movie (45.4%), and the least feature is the tag question (1.81%). Regarding the reasons for using Women's Language Features as the most frequent feature in this movie, the feature occurs when the speakers try to give a strong opinion or persuade the other person. Furthermore, the reason of tag question occurs in this movie because to convenience the hearer about what the speaker’s said.
NASIONALISME DARI PERSPEKTIF FOUNDING FATHER (SEBUAH ANALISIS PSIKO-HERMENEUTIK)
Authors: Alfaruqy Muhammad Zulfa
Published: May 2023

The purpose of research is to understand the meaning and dynamics of nationalism of a founding father, namely Ir. Soekarno. The research used qualitative methods with psycho-hermeneutic approaches. The research involved a single subject, Namely Ir. Soekarno. The results showed that nationalism contains consistent interactions between affective, cognitive, and conative. This is seen from the meaning of nationalism as a feeling of pride towards the group perceived as a nation-state on the basis of identity awareness that itself is a unified part of the group (in-group). Manifestations of nationalism in the form of political behavior create in-group unity and achieve independence from the domination of other nations (out-group). Meaning was gained through lifelong dynamics identified over four segments: partial, pre-integration, integration, and post-integration segments. Nationalism is an important element in the life of the nation and state. The soul of nationalist patrons, such as Ir. Soekarno, became relevant to be reread to be realized by all the nation's children.

Happiness is the goal of the American dream; a means to reach happiness is wealth; in the following turn, wealth cannot be gained without optimism, opportunities, and hard work. Meanwhile, the massive use of conceptual metaphor raises the question of whether all of the domains, namely optimism, opportunities, hard work, wealth, and happiness were expressed in metaphor in the Great Gatsby whose theme is the American dream. The data collection technique was document analysis. The data were differentiated from the non-data, taxonomized, analyzed their components, and analyzed their dominance.  The results show that all domains of the American dream are expressed in all types of metaphors. Structural and ontological metaphors have slight differences in terms of sum. The orientational metaphor, however, has an extreme gap compared to the first two metaphors.Key words: American dream, metaphor, conceptual, expression
