In vitro bio-efficacy of the novel copper (NC101 and NCP102) and phosphonate
(PN103 and PMN104) based fungicides against various soil borne and grape
vine pathogens was evaluated at ICAR-National Research Centre for Grapes,
Pune, Maharashtra, India during February - April 2021. The fungicides were
screened against five bacterial pathogens viz. Xanthomonas campestris pv. citri,
X. campestris pv. campestris, X. campestris pv. punicae, X. campestris pv. viticola
and X. oryzae pv. oryzae and 10 fungal pathogens viz. Rhizoctonia bataticola,
Sclerotium rolfsii, Cladosporium sp, Alternaria alternata, Colletotrichum
gloeosporioides, Penicillium notatum, Magnaporthe oryzae, Fusarium oxysporium,
Macrophomina phaseolina (Soyabean isolate) and Macrophomina phaseolina
(Jute isolate) at different concentrations. Results indicated that among all the
tested fungicides viz. NC101, NCP102, PN103 and PMN104, phosphonate based
fungicides (PN103 and PMN104) were highly effective against bacterial isolates
with zone of inhibition ranging between 8.75 - 31.12 mm in which X. campestris
pv. viticola was found to express least inhibition zone. In case of pathogenic fungal
isolates, similar trend was observed, most of the isolates showed cent percent
inhibition at higher concentration of PN103 and PMN104. However Sclerotium
rolfsii showed least or no inhibition when tested at different concentrations of
fungicides. The chemicals exhibited wide range of inhibition and it was found to
increase steadily with increase in concentrations of the test fungicides.
