Pseudomonas fluorescens cultures were isolated from rhizosphere of rice cultivated in different locations of Kuttanad. Three effective strains viz., PF 43, PF 46, PF 47 and combined isolates PF 43+PF 46+PF 47 were tested in the farmers plot of nine different locations of Kuttanad against rice sheath blight disease during Rabi 2011-12. The data on disease incidence and severity indicated that the combined isolate was performed well in restricting the disease incidence and severity. The pooled data showed that combined strains of PF 43+46+47 was found most effective against sheath blight disease and thereby increased the grain yield than other single isolates as well as standard fungicide check.Keywords

The compatibility of Pseudomonas fluorescens with 15 fungicides, 9 insecticides and 10 weedicides was tested under laboratory condition. All insecticides, herbicides and 12 fungicides except saaf, kocide (copper hydroxide) and zineb were found to be compatible with P. fluorescens. The study indicated that most of the fungicides, insecticides and weedicides can be mixed with P. fluorescens for use in agriculture.Keywords

Pure cultures of bacterial antagonist, Pseudomonas fluorescens were isolated from different locations in Kuttanad for screening against rice sheath blight disease. Three effective strains, viz., PF43, PF46 and PF47 were tested individually and also in combination against sheath blight under field conditions. Combined application of PF43, PF46 and PF47 was found to be effective for sheath blight disease management during rabi 2009-10, kharif 2010 and rabi 2010-11.Keywords

Bacterial antagonist fluorescent pseudomonads for sheath blight disease were isolated from different locations in Kuttanad region. Three effective strains viz., PF 43, PF 46 and PF 47 were tested along with standard culture P 1 against sheath blight disease of rice under glass house condition. The confirmation tests viz., physiological and biochemical characterization of the efficient isolates were carried out at Rice Research Station, Kerala Agricultural University, Moncompu. Various physiological tests on growth at different pH, Iron toxicity and Aluminium toxicity level showed that the isolate PF 43 grew at pH ranging from 1.0 to 14 and tolerated upto 1000 ppm of iron toxicity and 90 ppm of aluminium toxicity level. The biochemical tests indicated that three efficient isolates were confirmed as gram negative, rod shaped, fluorescent in King's B medium and positive response for growth at 4°C, Levan formation, Gelatin liquefaction and Catalase tests. However, there was a negative response for growth at 41°C, Methyl red, VogesProskaur and Indole tests. Thus, based on morphological and biochemical characteristics, the isolated strains were identified to be Pseudomonas fluorescens. P. fluorescens PF 43 product survived upto 150 days with required population of 1.01 to 1.63 × 108 cfu per g in talc, dolomite and gypsum based formulations. At 240 days of storage, 1 × 107cfu were detected in talc, dolomite and gypsum based formulations. The cheap and easily available carrier material, gypsum and dolomite can be used for mass production of native P. fluorescens and is recommended to 66,000 ha rice growing tracts of Lower, Upper and Karilands of Kuttanad regions like Alleppey, Kottayam and Pathanamthitta District for ecofriendly management of diseases.Keywords

Bacterial antagonist, Bacillus spp. cultures were isolated from different places of Kuttanad region. Three effective endophytic Bacillus strains viz., B 15, B 17 and B 33 were tested in the separate field experiments against sheath blight and bacterial blight diseases of rice during Kharif 2017, Rabi 2018-19, Kharif 2019 and Kharif 2020. In the field study, the Bacillus cultures were treated as standard bioagent application methods of seed (10 g/kg), soil (1 kg/acre) and foliar (20 g/litre of water) spraying against the major diseases in rice. The rice associated native Bacillus cultures B 15, B 17 and B 33 were found equally effective for the sheath blight and bacterial blight diseases management. All the three native Bacillus species can be used as potential biopesticides against rice sheath blight and bacterial diseases in Kuttanad region.
