A total of seven isolates were collected from major chickpea growing areas of Kurnool, Anantapur, Prakasam and Kadapa districts of Andhra Pradesh. The pathogen was isolated from infected leaves and pods and pathogenicity was confirmed. Disease severity test was conducted in which the isolate collected from Kurnool i.e., Cb 2 showed maximum disease severity than other isolates. Further Cb 2 was used for in vitro evaluation of fungicides and bio-control agents. Fungicides and bio-control agents were evaluated by pot culture experiment against the pathogen on popularly cultivated variety, JG-11 by imposing 12 treatments. Management of pathogen by fungicides and bio-control agents in pot culture experiment revealed that fungicide tebuconazole (0.1%) is more effective against the pathogen with less Per cent Disease Index (PDI) of 17.33 and more disease reduction of 73.00 followed by difenconazole (0.1%), hexaconazole (0.2%), kresoxim methyl (0.1%). Mancozeb + cymoxanil (0.25%) recorded PDI of 48.33 and disease reduction of 42.00 which is least effective against pathogen. Among the bio-control agents tested Trichoderma koningii, (0.4%) with PDI and disease reduction of 25.33 and 65.00 respectively was more effective followed by Trichoderma harzianum (0.4%) with PDI and disease reduction of 28.67 and 61.67 respectively.

Naffaa W. and Paul V. H. 2009. Effect of legume seed treatments by some fungicides to control Phoma spp., agent of root-rot disease. Damascus University Journal. 25. 1. Pp. 135 – 149. Efficacy of six foliar fungicides [Capitan (a.i. flusilazole), Harvesan (a.i. flusilazole + carbendazim), Prosaro (a.i. prothioconazole + tebuconazole), Boscalid+D (a.i. dimoxystrobin + boscalid), Proline (a.i. prothioconazole) and Cantus (a.i. boscalid)] were tested in vitro against two Phoma species (P. medicagnis var. pinodella and Phoma lingam). The efficacy of fungicidal seed treatments against P. medicagnis var. pinodella on eight species of legumes were tested: three German cultivars of Pisum sativum (cv. Santana, Respect and Starter); three Syrian cultivars of Cicer arietinum (Ghab3, Ghab5, and domestic); a Syrian cultivar of Lens culinaris (Kurdey) and a cultivar of Vicia faba (Egyptian bean). The results showed that mycelium growth of P. lingam isolates were sensitive to the tested fungicides independent on the concentrations, while the effect of the fungicides on the growth of P. medicagnis varied according to the kind of fungicide and its concentration. The order of effectiveness in vitro was: Capitan > Harvesan = Prosaro> Boscalid+D > Proline > Cantus. The foliar fungicides used as a seed treatment failed to prevent the disease occurrence and the appearance of symptoms, nevertheless they improved protection of the seedlings at the time of emergence, and the symptoms were delayed in comparison with the infected control, especially for the sensitive cultivars. The fungicidal effect differed according to the plant species/cultivar. Certain fungicidal seed treatments showed a clear effect on plant growth: Capitan had a significantly negative effect on plant growth compared with other treatments, especially for Ghab3 cultivar of chickpea, and for the three cultivars of pea, while Boscalid+D was superior to the other fungicides followed by Cantus that increased the growth of pea plants significantly. These experiments demonstrated that Ghab3 was the most sensitive cultivar of chickpea to P. medicagnis, while Ghab5 was the most resistant. No clear difference showed between the pea cultivars concerning their sensitivity to P. medicagnis, although the cultivar Respect seems to be more sensitive.

Pigeonpea is an important pulse crop in India, accounting for almost 90% of world's area and production, affected by the several pathogens. Wilt caused by Fusarium udum is a most important disease of Pigeonpea. A trial was conducted to evaluate the effectiveness of above selected biocontrol agents against the wilt of pigeonpea under pot condition. The treatments were Trichoderma viride @ 5gm/kg of soil, T. harzianum @ 5gm/kg of soil with FYM and without FYM against the Fusariun udum as soil treatment and Neem cake, Carbendazim also taken for comparison in the pot conditions. All the treatments was significantly reduce the wilt incidence but Trichoderma viride with (88.89 %) disease inhibition recorded most effective followed by T. viride +FYM (87.84 %), Carbendazim (87.13 %), T. harzianum (81.22 %), T. harzianum+FYM (80.04 %), Neem cake (70.61 %) over the control. The germination percentage was also increase with all treatment but T. viride was increase highest germination percentage followed by rest of treatments over the control.

Anthracnose of chilli is one of most important disease causing great economic loss. Anthracnose may cause yield losses up to 50 per cent. There is varied range of chemical fungicides available in the market for controlling this pathogen, viz. Colletotrichum capsici, but the extent of inhibition varies with different fungicides. Five fungicides viz. Kasugamycin (Kasu B 3%SL), Pyraclostrobin + Metaram (Carbrio Top 60%WG), Azoxystrobin (Onestar 23%SC), Fusilazole (Cursor 40%EC) and Carbendazim (Dhanustin 50%WP) were assayed for their efficacy against Colletotrichum capsici by Poison food technique. These fungicides were prepared at two concentrations viz. 250 ppm and 500 ppm concentration, evaluated for their toxicity against Colletotrichum capsici under in vitro condition using poisoned food technique. Under in vitro condition, all the fungicides which were tested against the growth of the fungus Colletotrichum capsici proved to be effective. Carbrio Top 60% WG was found highly effective with mycelia growth inhibition (72.66%) followed by (Azoxystrobin) Onestar 23%SC, (Fusilazole) Cursor 40%EC, (Carbendazim) Dhanustin 50%WP and (Kasugamycin) Kasu B 3%SL at 250 ppm with inhibition percentage of 60.78%, 43.77%, 31.1% and 24.4% respectively. Similar trend were obtained at 500 ppm also, the mycelial inhibition percentages were 81.45%, 72.33%, 66.67%, 52.4% and 35.2% respectively.

Chilli (Capsicum annuum) is one of the major cash crops in India. Chilli crops are affected by fungal, bacterial and viral diseases. However, fungal diseases are found to be the major factor to constraint of the chilli production. For the control of these disease used mostly used fungicides which are reduced their severity and suppress their growth. In the present investigation used seven fungicides viz., Carbendazim, Captafol, Thiram, Azoxystrobin 23% SC, Hexaconazole 2% SC, Chlorothalonil 75% WP and Indofil M-45. All the treatments were found superior on the control and reduced fungal growth. Most effective fungicides found Carbendazim in both the year which reduced fungal growth and increased yield while the yield over the control plot. Maximum fruit yield (17.93 and 16.70 q/ha) was recorded with foliar spray of Carbendazim 600 ml/ ha which was at par with foliar spray of Captafol 500 ml/ha (17.32 and 12.03 q/ha) and significantly superior over rest of the treatments, during 2012...

Efficacy of bio agents and systemic and non-systemic fungicides @ 50, 100, 200, 250 and 500 ppm were evaluated In vitro against Alternaria tenuissima causing Alternaria blight of pigeonpea. The relative efficacy of bio agents were studied in dual culture plate method showed that Hypocrea rufa was found most effective antagonist against test pathogen followed by T. harzianum. Efficacy of six fungicides was tested in poisoned food technique. Among the six fungicides tested, mancozeb was found most effective against test pathogen followed by Chlorothalonil and Iprodione. Propineb was least effective against mycelial growth of test pathogen. Raise in concentration of fungicides was more effective in inhibiting the mycelial growth of the pathogen. Field condition studies were found out to be the effect of seed treatment, foliar spray, seed treatment+ foliar spray with six fungicides and two bio agents and their combination used as against pathogen. Artificial inoculation of mass culture ...
