THE ROLE OF SOYBEAN SEED IN THE EPJDEMIOLOGY OF DIAPORTHE PHASEOLORUM VAR C4ULIVORA

by

M Vfdtc and s Jasnlc Faculty of Agriculture Novi Sad

Summary

Diaporthe phaseolorum var caulivora is important parasite of soybean in Yugoslavia The epidemiology of the fungus especially seed transmission is no t completly clear

Diaporthe phaseolorum var caulivora can infect the soybean seed The seed could be infected only when the pods of soybean are form The pathogen can not reach the seed through stalk during the process of feeling the pods but the infection occurgt through pods by airborne ascospores

The infection established in seed did not significantly effect the germination but did influence the vigor what we suppose was the consequence of poor grain feeling of the diseased plants

The presence of the pathogenic fungus in the seed could cause seed rot and seedlings decay When planted the ineflttcd seeds did not yield the plants with wmptoms

THE ROLE OF SOYBEAN SEED IN THE EPJDEMIOLOGY OF DIAPORTHE PHASEOLORUM VAR C4ULIVORA

by

M Vfdtc and s Jasnlc Faculty of Agriculture Novi Sad

Summary

Diaporthe phaseolorum var caulivora is important parasite of soybean in Yugoslavia The epidemiology of the fungus especially seed transmission is no t completly clear

Diaporthe phaseolorum var caulivora can infect the soybean seed The seed could be infected only when the pods of soybean are form The pathogen can not reach the seed through stalk during the process of feeling the pods but the infection occurgt through pods by airborne ascospores

The infection established in seed did not significantly effect the germination but did influence the vigor what we suppose was the consequence of poor grain feeling of the diseased plants

The presence of the pathogenic fungus in the seed could cause seed rot and seedlings decay When planted the ineflttcd seeds did not yield the plants with wmptoms

SUGARBEET RHIZOMANIA IN MACVA REGION

by

Branka Krstic and M Tollcent Facully of Agricultural Beograd-lcmun

Summary

By surveying and investigations done in 1989 it was shown that sugarbeet rhizomania is present in Macva region The presence of the disease in mentioned region was confirmed by symptoms on diseased sugarbeet plants as well as by Dot-blot serological analysis This is first report of sugarbeet rhizomania presence in Macva

faculty of Agriculture Novi Sad

Summary

Phomopsis permcwsa Growe was isolated in 1988-89 at Ca~ak (western Serbia) from the diseased branch and fruit tissues of apricots with apoplexy symptoms

The isolates were used to inoculate the fruits which had been previously wounded and the unwounded fruit s The wounded fruits developed symptoms and reproductive organs of the fungus (molds and pycnidia) After 1~15 days cankers appeared on inoculated branshyches and pycnidia developed within several weeks The dieback of branches occurred after 10 months

Apricot peach and walnut showed susceptibility to this isolate after artificial inoculation whereas vine and blackberrv were not afshyfuc~d middot

The pycnidia arc hemispherical or spherical-conical black surshyrounded at the base by black torula-like hyphae

a-conidia are elongated spindle-shaped rounded at the ends coshylourless unicellular 68-91 X 1-15 Jln The conidiophores are 16-21 JID in lenght

~-conidia are filiform thin colourless curled at one end 23-32X x 1-17 pm

Summary

On the ashes depots in Serbia significant efforts have been made in order to turn back these area to their orjgin purpose - plant promiddot duction This mechanical substrate is gradually changed and becomes more and more stabile by growing vegetables and fruits ln such a way it appears to be a specific biotop where cenotical completes of a nomshyber of organisms mcluding Arthropoda are formed and get stable

This paper deals with the structure and dynamics of the Heteroshyptera population on ashes depot in recultivation with alfalfa planted in 1984 and 1986 ie poplar trees planted in 1981 and a mixture of poplar and black locust planted in 1976

The study of the structure ond quantitative relations of the Heshyleroptera populations on the fields covered with the alfalfa poplar trees and mixed wood indicates 49 bedbug species of 10 families The greatest number of representatives belong to the Miridae family fol shylowed by the families mentiqned below Pentatomidae Lygacidae Phishypalidae and Nabidae

More species and specimens are reported for the fields under reshycultivation than for the wood communities which suggests the openshyness of the community the bioproduction and this culture as suitable host The heterogenity of the Heteroptera population is proved by a very few species found in 4 localities

In these initial Hetroptera communities a new species of the fauna of Serbia has been identified - Oncotylus setulosus of the Miridae fashymily

Summary

On the ashes depots in Serbia significant efforts have been made in order to turn back these area to their orjgin purpose - plant promiddot duction This mechanical substrate is gradually changed and becomes more and more stabile by growing vegetables and fruits ln such a way it appears to be a specific biotop where cenotical completes of a nomshyber of organisms mcluding Arthropoda are formed and get stable

This paper deals with the structure and dynamics of the Heteroshyptera population on ashes depot in recultivation with alfalfa planted in 1984 and 1986 ie poplar trees planted in 1981 and a mixture of poplar and black locust planted in 1976

The study of the structure ond quantitative relations of the Heshyleroptera populations on the fields covered with the alfalfa poplar trees and mixed wood indicates 49 bedbug species of 10 families The greatest number of representatives belong to the Miridae family fol shylowed by the families mentiqned below Pentatomidae Lygacidae Phishypalidae and Nabidae

More species and specimens are reported for the fields under reshycultivation than for the wood communities which suggests the openshyness of the community the bioproduction and this culture as suitable host The heterogenity of the Heteroptera population is proved by a very few species found in 4 localities

In these initial Hetroptera communities a new species of the fauna of Serbia has been identified - Oncotylus setulosus of the Miridae fashymily

THE INFLUENCE OF SOME HERBYCIDES ON TOTAL SOIL MICROFLORA AND TUBEROUS SOYBEAN BACTERIAS

(RHIZOBIUM JAPONICA)

by

v Bogdanovic Faculty of Agriculture Beograd-Zemun

Summary

Investigations have included eght herbycides combinations mostshyly used in soybean production and they were carried out in the year 1985 The samples were taken two times (summer and autumn) from two depths 0--10 em and 10-20 em

All these herbycides combinations had an depressive action in summer condition on the total soil microflora from 150o Alaklor + Afashylon to 75 - Stomp + Afalon

Meanwhile in autumn samples this picture was changed so - Alashyklor + Afalon increase their deperession up to 69 the others dealay deperession and some of them in autumn conditions show an positive action on total rnicroflora from 5 to 21o

All herbycides used in these investigations have acted on the numshyber increase of tuberous on soybean root with different intensity from 1211o to 437

From the standpoint of their influence on soybean all of them have acted depressively on the height of overground mass from 10--401o The action on the root system lenght was different some of them deshyperssive1y 5-14dego and the others stimulatively from 6-44
