Dry root rot of chickpea
-
Chickpea (Cicer arietinum L.) is the third most important pulse crop of the world grown in semi- arid and tropical climate. It belongs to family Fabaceae. The major losses in chickpea yield are attributed mainly due to soil borne pathogens. Among them the dry root rot (DRR) caused by Rhizoctonia bataticola has become a major threat to chickpea production in recent years.

In cultural characteristics six characters like colony colour, colony diameter, pigmentation, margin type, growth pattern and aerial hyphae were recorded. Maximum radial growth i.e. 90 mm was given by isolate Rb-07 of Sabalpur village followed by Rb-02 and Rb-12. Least radial growth of 45 mm was given by Rb-03 isolate of Nandpur village. Pigmentation was also observed in four isolates. Aerial hyphae were produced by six isolates.

India is the largest producer and consumer of chickpea, contributing an elephant share (65 per cent) towards the global chickpea production. However, in recent past the changing climate has lead to the emergence of Dry root rot (DRR) disease in chickpea growing areas, which frequently encounters a prolonged dry spells coupled with high temperature. The disease is posing serious threat to chickpea cultivation by pronounced effect of devastation in susceptible cultivars.

Wilt and root rot diseases of chickpea caused by Fusarium oxysporum f. sp. ciceri and Macrophomina phaseolina are serious biotic constraints for chickpea (Cicer arietinum L.) production. These are most important and widespread soil- and seed-borne diseases of chickpea grown where the climate is relatively dry and warm.

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.

Cultural and genetic diversity of Rhizoctonia bataticola causing dry root of chickpea (Cicer arietinum L.) crop were studied during 2018-19 at VNMKV, Parbhani. In present studies, isolate Rb-6 , exhibited maximum mycelial growth of (90.00mm), followed by Rb-9 (89.50mm) and Rb-2 (88.50mm) indicated a great cultural variability amongst R. bataticola isolates, whereas, in case of genetic variability when a dendrogram generated based on UPGMA analysis of RAPD data grouped all of the 9 test isolates (R. bataticola) into two major clusters. The cluster I included 6 isolates viz.

Chickpea is a major pulse crop being grown for rich source of protein and form an important part of vegetarian diet and the crop being affected by various diseases; the wilt caused by Fusarium oxysporum f. sp. ciceri is a important disease occurs in many parts of the country and the pathogen in association with other soil-borne pathogens like root rots and stem rot also causes extensive damage to chickpea crop.

Chickpea (Cicer arietinum L.) is an important cool-season food legume grown extensively by the poor farmers throughout the Indian subcontinent. In India chickpea is being grown in 8.32 million hectare with production of 9.8 million tones and 925 - kg/ha productivity (Project coordinators report, 2014-15). The Dry root rot (DRR) of chickpea caused by necrotropic fungus Rhizoctonia bataticola.

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.

Chickpea dry root rot is caused by Rhizoctonia bataticola is the most destructive disease and causes severe losses in yield. Therefore, the present investigation were undertaken to screen different genotypes for their resistance to dry root rot. One hundred twenty seven chickpea genotypes were evaluated for locating new and better sources of resistance against dry root rot through disease sick fields at IGKV, Raipur during 2012 to 2013.

Dry root rot caused by Rhizoctonia bataticola (Taub.) Butler is emerging as a serious biotic constraint for chickpea production. It is soil borne fungal pathogen. The losses in chickpea due to Rhizoctonia bataticola may be as high as 60 per cent. The eight isolates of Rhizoctonia bataticola were collected from different districts of Maharashtra. The genomic DNA of 8 isolates of Rhizoctonia bataticola isolated from fresh mycelium of fungus grown in Potato Dextrose Broth solution and subjected to amplification with RAPD marker for diversity analysis.

Dry root rot caused by Rhizoctonia bataticola (Taub.) Butler is emerging as a serious biotic constraint for chickpea production. It is the most important and widespread soil borne disease of chickpea. Among the several constraints affecting the productivity of chickpea, 10-35 per cent loss in yields are due to dry root rot diseases.

Chickpea (Cicer arietinum L.) is one of the most important food legumes and India accounts for approximately 75% of world’s chickpea production. Despite the high total production, yields of chickpea are low due to many biotic and abiotic constraints. Among the biotic constraints more than 50 diseases have so far been reported on chickpea.

Chickpea, (Cicer arietinum L.) is one of the most important pulse crops of India, which belongs to family Fabaceae. It occupies very important position in semiarid farming system both for human nutrition and restoring the soil fertility. Occurrence of dry root rot caused by Rhizoctonia bataticola (Taub.) Butler is emerging as a serious biotic constraint in recent years for successful and profitable cultivation of chickpea the efficacy of various fungicides viz.

An experiment was conducted to study the nutritional requirement and effect of physiological parameters like temperature and pH on mycelial growth of different isolates of Macrophomina phaseolina causing dry root rot of chickpea. Five different solid media, five temperature range and five pH levels were tested for their effect on mycelial growth. All tested culture medium, temperatures and pH levels supported the mycelial growth of different M. phaseolina isolates. The potato dextrose agar was found better for mycelial growth of all the isolates followed by Czapek’s dox agar. M.

Among the four bioagents evaluated for their efficacy in inhibiting mycelial growth of Rhizoctonia bataticola causing dry root rot of chickpea by dual culture technique. The results indicated that T. harzianum is highly antagonistic to Rhizoctonia bataticola by suppressing its growth by 78.67 per cent. Paper towel method was also followed to test the efficacy of bioagents in suppressing the seedborne infections. Among the four bio-agents with three concentrations viz., 0.4 %, 0.8 % and 1.
