Abstract



Bu çalışmanın amacı, in vitro ve sera koşullarında bazı önemli mantarların koloni
gelişimi ve sporulasyonu üzerine tepraloxydim, fluazifop-p-butyl ve metribuzin
herbisitlerinin etkisini analiz etmektir. Çalışma sonucunda tepraloxydim 2x10-3M
yüksek dozda Rhizoctonia solani’nin
koloni gelişimini %88.93 oranı ile en üst düzeyde engellemiştir. Tepraloxydim
5x10-5M’de, %0.21 oranı ile R.
solani’nin koloni gelişimini en düşük seviyede engellemiştir. Bununla
birlikte,
tepraloxydim’in düşük
doz seviyesinde Phoma destructiva’nın
büyüme oranında azalma olmayıp, koloni gelişimini (%1.29) artırmıştır.
Çalışmanın sonucunda, in vitro koşullarda fluazifop-P-butyl’in yüksek doz uygulamasında
2x10-3M R. solani’nin
koloni gelişimini tamamen engellenmiştir. Herbisitin düşük doz 5x10-5
M uygulaması, P. destructiva koloni
gelişimini en düşük doz seviyesinde (%4.68) azaltmış, ancak R
hizopus stolonifer’in
koloni gelişimini (%4.14) artırmıştır. In
vitro
koşullarda metribuzin’in yüksek doz 2x10-3M uygulamasında Rh. stolonifer’in koloni gelişimini en
yüksek seviyede (%63.47) engellediği ve ayrıca en düşük doz 5x10-5M
uygulamasında Cladosporium fulvum’u
en düşük seviyede gelişimini (%2.51) engellemiştir. Sera koşullarında tepraloxydim’in yüksek doz
(%50 fazla) ve düşük doz (%50 düşük) uygulamalarında sporulasyonu en çok
etkilenen fungal patojen
Alternaria
alternata
(1.2x102 spor/ml; 2.7x102 spor/ml)’dır.
Sera koşullarında yüksek doz (%50 fazla) uygulamasında fluazifop-p-butyl’in en
çok etkilediği patojen
Stemphylium
solani
(1.6x102 spor/ml)’dir.
Fluazifop-p-butyl herbisitin düşük doz (%50 düşük) uygulamasında fungal
sporulasyonu en çok etkilenen patojen A. alternata (3.0x102
spor/ml)’dır.
Serada metribuzin yüksek
doz uygulaması çoğunlukla Fusarium solani ve Rh. stolonifer’i
etkilemiştir.
F. solani ve Rh. stolonifer’in son sayıma göre
belirlenen toplam spor sayıları 2.5x102 spor/ml’dir. Düşük doz
uygulamasında A. alternata sporlarının
sayısı 4.1x102 spor/ml’dir.

Abstract



The objective of this study was to analyze the effect
of herbicides tepraloxydim,
fluazifop-p-butyl and metribuzin on colony development and
sporulation of some important fungi in in
vitro
and greenhouse conditions.
At the end of the study,
tepraloxydim at high dose of 2x10-3M prevented Rhizoctonia solani colony growth at the highest level with the rate
of (88.93%). Tepraloxydim at 5x10-5M inhibited R. solani colony growth at the lowest level with the rate of
(0.21%). However, the growth rate of Phoma
destructiva
could not be decreased at this low dose level, but increased
the growth of colony by (1.29%). As a result of
study, the colony development of R. solani
in in vitro conditions was
completely inhibited at high dose application (2x10-3M) of
fluazifop-p-butyl. At low dose (5x10-5M) application
of herbicide, the colony development of P.
destructiva
was decreased by (4.68%) at the lowest dose level, but
increased colony development of
Rhizopus
stolonifer
by (4.14%). Metribuzin prevented
colony development of
Rh.
stolonifer
at the highest dose level of 2x10-3 M by (63.47%) and
the highest dose of application

in
in vitro conditions,
It also
prevented the development of Cladosporium fulvum at the lowest level
(2.51%)
when applied at 5x10-5
M.
Tepraloxydim at above and below (50%) affected
sporulation of fungal pathogens with Alternaria
alternata
most affected (1.2x102 spore/ml; 2.7x102
spore/ml) under greenhouse conditions. High dose
(above concentrations of 50%) application of fluazifop-p-butyl mostly affected Stemphylium solani (
1.6x102 spore/ml
) in
greenhouse conditions
. A. alternata (3.0x102 spore/ml) was the mostly
influenced pathogen for fungal sporulation at low dose (below 50%) application
of fluazifop-p-butyl herbicide
. High dose application of
metribuzin mostly affected
Fusarium solani and Rh. stolonifer in greenhouse. The total number of spores determined at the last
count for
F. solani and Rh.
stolonifer
was (2.5x102)
spore/ml. The number of A. alternata
spores at low dose application was (4.1x102) spore/ml.
