Turmeric (Curcuma longa L.), is an important and economical medicinal and aromatic crop, prone to many fungal, bacterial, viral and nematode diseases. The most important fungal diseases are leaf spot (Colletotrichum capsici), leaf blotch (Taphrina maculans), rhizome rot (Pythium aphanidermatum) etc.,

The disease has been reported to causes more than 60 per cent mortality of seedlings both in nursery and field condition and about 50-80 per cent losses during storage (Nirmal, 1992); rhizome rot resulted in yield loss of 50% (Rajalakshmi et al., 2016).

Thirty varieties of turmeric Curcuma longa L. were screened in the field against Pythium aphanidermatum for one year during 2016-2017 at College of Horticulture, Anantharajupeta, Y.S.R. Kadapa, Andhra Pradesh. These varieties were also screened in lab and net house (pot) condition. Out of 30 varieties two varieties (Salem and Prathibha) showed resistance to rhizome rot and five (TCP-129, VK-9, IC-330113, IC-033007 and IC-212606) were moderately resistant, providing good material for developing rhizome rot resistant turmeric varieties.

Rhizome rot or tip over disease of banana has been occurring in serious form and affecting the yield wherever bananas are being cultivated. The morphological characteristics of the eighteen isolates of the bacterium revealed that cells were rod shaped, occurred singly, Gram negative and peritrichously flagellated. The pathogen was identified on the basis of cultural, morphological and biochemical characteristics and its pathogenicity in banana was proved using Koch‟s postulates.

Rhizome rot and yellows caused by Fusarium oxysporum f. sp. Zingiberi, is a serious a serious soil-borne disease of ginger and found to be prevalent in the north-east region of India. Most of the plant disease resistance (R) genes encode a highly conserved nucleotide binding site and leucine-rich repeat structure (NBS-LRR).

The present study was conducted to evaluate bacterial endophytes against Pythium spp. causing soft rot of ginger. Water soaked lesions at the emerging base and the collar region was the typical symptoms observed on infected plants. Sprout appeared pale yellowish and withering off of plant was seen and such rhizomes were rotten and emitted foul smell in which diseased plants came off with a gentle pull.

Rhizome rot of ginger is both seed (rhizome) and soil borne disease and soil plays an important role in the disease incidence and severity. Soil physico chemical properties play an important role in disease severity of rhizome rot of ginger. Correlation studies of six soil physico-chemical parameters with disease incidence (DI) showed that Potash (K2O) content in soil was found exhibit significant negative correlation (-0.78). A ready to use regression equation has been developed to predict the incidence of rhizome rot disease in ginger with R2 value of 61 per cent.

Bacteria producing biosurfactant molecules is beneficial to manage rhizome rot of turmeric caused by Pythium spp. A detailed study was conducted on biosurfactant producing bacteria for management of rhizome rot of turmeric. Initially, a survey was conducted to find out the incidence of the disease in turmeric growing of areas of Tamil Nadu, it was observed that rhizome rot in turmeric was also ranged from 9.16 to 71.55 and the maximum incidence was noticed in Ammampalayam (71.55%).

Nine botanicals were evaluated for their antifungal activity against Fusarium solani causing root rot disease in Bael by employing poisoned food technique under laboratory conditions. The results indicated that all the botanicals inhibited the growth of the Fusarium solani as compared to control. Out of nine botanical tested, turmeric rhizome extract was found most effective as it showed minimum mycelial growth (33.3 mm, 20.7 mm and 13.5 mm) and maximum mycelial growth inhibition (63.1 %, 77.0 % and 85.

Turmeric is one of the important spice crops grown in India. Root-knot nematode (Meloidogyne spp.) is a major problem, which causes galls/knots in the rhizomes and causes considerable yield loses. It also makes the way for the secondary infection by different pathogens like Pythium, Fusarium and Ralstonia in the soil. Yield losses due to nematode infestation are reported in turmeric-growing areas. A roving survey was conducted for incidence of root-knot nematode in turmeric during kharif season in 2016 at Belagavi, Bagalkot, Chamarajanagar and Kalburgi districts of Karnataka.

Turmeric (Curcuma longa L.) is well known for its medicinal value, its cultivation is hindered by several diseases viz., leaf spot, anthracnose and rhizome rot. These diseases are managed by using the fungicides, which leads to development of resistant strains besides the environmental pollution and also the residue problem on final produce.
