Fungicides against Macrophomina phaseolina
-
Different non systemic and systemic fungicides are tested at four concentrations under in vitro over Macrophomina phaseolina causing charcoal rot of soybean. Among seven non systemic fungicides, mancozeb 75% WP and propineb 70% WP were found to be the most effective fungicides with cent per cent mean mycelial inhibition at all concentrations (1000, 1500, 2000 and 2500 ppm) tested.

In this study, two bio-control agents, Trichoderma viride and Pseudomonas fluorescens were assessed for their ability to reduce the growth of M. phaseolina under laboratory conditions. It was found that among the antagonists tested, Trichoderma exhibited strong inhibition (77.77%) against M. phaseolina.

Chemical control is one of the measures to manage the disease and avoid the losses. The evaluation study was therefore conducted in vitro. Ten fungicides were tested against the pathogen i.e. Macrophomina phaseolina in vitro. The highest inhibition (100%) of M. phaseolina was observed due to carbendazim 50% WP at different concentration (250, 500, 1000 ppm), mancozeb 75% WP (1500, 2000, 2500 ppm), ridomil-MZ 72% WP (1000, 1500, 2000 ppm) and carbendazim 12% + mancozeb 63% (1500, 2000, 2500 ppm) followed by propiconazole at 250 ppm (87.21 %), 500 ppm (89.92 %) and 1000 ppm (92.

Among the diseases of safflower; dry root rot disease caused by Macrophomina phaseolina (Tassi.) Goid is one of the most destructive and wide spread diseases of Safflower (Carthamous tinctorius L.) causing accountable losses of about 25-60 per cent. A total of ten fungicides namely: Captan, Iprodine, Copper Oxychloride, Thiram Mancozeb, Difenconazole, Propiconazole, Cymoxanil8%+Mancozeb 64%, Carbandazim, & Metalaxyl 8% + Mancozeb 64% were evaluated in vitro against Macrophomina phaseolina.

Chickpea (Cicer arietinum L.) is one of the major legume pulse crops and it is majorly grown in India and other semi-arid regions of the world. Dry root rot of chickpea is the most destructive disease of chickpea. Therefore, in present studies fungicides (six systemic, seven non systemic and six ready mix fungicides) were tested in vitro at three different concentrations by poisoned food technique for evaluating their efficacy against M. phaseolina.

Six fungicides viz., Tebuconazole + Trifloxystrobin 75 WG (Nativo), Hexaconazole 5% + Captan 70 % WP (Taqat), Carboxin 37.5% + Thiram 37.5% WP (Vitavax power), Iprovalicarb 5.5% + Propineb 61.25%WP (Melody duo), Carbendazim 50WP (Hycarb), Mancozeb 63% W.P. + Carbendazim 12% WP (Top too) were evaluated in vitro to test their efficacy against Macrophomina phaseolina by poisoned food technique. Results revealed that all the fungicides were effective in inhibiting mycelial growth of M. phaseolina to varying degrees.

Root rot of soybean is an important disease of soybean inflicting heavy losses in crop. The present investigation was carried out to test the efficacy of agrochemicals and fertilizers in vitro. In bioassay test of non systemic fungicides, Zineb 75 WP gave cent per cent inhibition of growth and sclerotial formation at minimum concentration of 500 ppm followed by copper hydroxide 77WP (53.63%).

Effect of eight antagonists viz., Trichoderma atroviride, T. harzianum, T. virens, T. fasciculatum, T. asperellum, T. viride, Pseudomonas fluorescens and Bacillus subtilis were studied for their antagonism against Macrophomina phaseolina by dual culture method and six fungicides viz. Azoxystrobin 23 SC, Carbendazim (12%) + Mancozeb (63%) 75 WP, Carbendazim (25%) + Mancozeb (50%) 75 WS were evaluated at two different concentrations (500 ppm and 1000 ppm) by poisoned food technique against the same pathogen.

The present experiment was planned integrated management of root rot pathogen in chickpea. Occurrence of root rot disease has become a major constraint in recent years for successful and profitable cultivation of chickpea. The efficacy of Bio-agent viz. Tricoderma viride, Organic amendment viz. neem cake, Plant extract, garlic, and Fungicide, Carbendanzim applied through seed treatment and soil application were evaluated against Macrophomina phaseolina causing root rot disease of Chickpea.

In recent years Macrophomina phaseolina causing stem canker of pigeonpea is more problematic in pigeonpea growing parts of Karnataka. Present investigation was taken on evaluation of non-systemic, systemic fungicides and bio-agents against M. phaseolina under laboratory condition. Five non systemic, four non systemic and three combi products were evaluated. Similarly two isolates of Trichoderma spp. four Pseudomonas fluorescens isolates, one Pseudomonas putida and one Bacillus subtilis were evaluated against M. phaseolina by poison food technique and dual culture method respectively.
