“…During measurement, leaf temperature was controlled at 30 °C, vapor pressure deficit between the leaf and air (VpdL) was maintained at 1.7 ± 0.3 μmol m −2 s (Gaihre & Nose, 2011), have been conducted. Although the yield of 32R (7.9 MT/ha) is lower than that of Nb (9.6 MT/ha) and 29S (8.8 MT/ha), the yield of the F 1 generation (by crossing 32R and Nb, 12.5 MT/ha) is greater than the parents (Gaihre & Nose, 2013). In addition, Kobayashi et al (2006) reported that the epidemic of the ShB would expand in rice grown under elevated CO 2 concentrations in the Northern Japan, thus the increased risks of ShB to rice plants are necessary to consider in the forecasting the effects of climate change on rice yield.…”

“…The decreases in growth and photosynthesis during the seedling stage of 32R at low temperatures compared to both 29S and Nb might be due to 32R containing characteristics of the cold-sensitive Indica genotype of Tetep. Although the 32R is cold-sensitive and low yield, it is ShB-resistant (Mutuku & Nose, 2012) and a high-yield potential (Gaihre & Nose, 2013).…”

“…Yield losses ranged from 1 to 50.0% due to sheath blight disease. Under severe disease conditions, it was reported up to 90% [108,144,35]. The loss and level of severity is depends on the environmental conditions, the growth stage at which the plant becomes infected, the degree of infection, and the rice varieties grown.…”

Rice is one of the most important crop planted on earth. It provide food and employment for thousands of persons daily through out the world. In Guyana the rice industry is one of the largest user of agricultural lands and contributies more than 20% to the country gross domestic product (GDP). The rice crop is known to suffer from several biotic and abiotic factors. Of which rice blast (P. oryzae) and sheath blight (R. solani) disease identified as two of the most devastating disease affecting the rice cultivation in Guyana. In this context, the present critical review article entitled 'Managing the imminent danger of Rice Blast (Pyricularia oryzae Cav.) and Sheath Blight (Rhizoctonia solani Kühn) Disease' was taken up to look at the most practical disease management approaches available and can be utilized to mitigate the imminent threat pose by the rice blast and sheath blight disease. The review will focus on: disease resistant screening and understand the genotype and environment interactions; study the expression pattern of proteins in resistant and susceptible genotypes against blast pathogen (P. oryzae); examine the efficacy of botanicals, biocontrol agents and new generation fungicides against blast and sheath blight disease under different conditions. This will form a foundation for the exploration of the various disease management stratigies for blast and sheath blight disease.

“…The continuous use of fungicide molecules with same mode of action led to the development of resistance in pathogens (Kunova et al, 2014). Furthermore, the overuse of highly hazardous chemicals resulted in pesticide residues and posed negative impacts to the environment (Gaihre and Nose, 2013;Rini and Dipankar, 2021). Therefore, it is needed to search for new generation fungicides with different mode of action to delay the development of resistance in fungi and to effectively control the disease.…”

Background: Blast is a devastating disease in rice production. The current research tested the efficacy of biologicals and fungicides against blast. Aqueous extracts of Azadirachta indica, Ocimum basalicum, Cymbopogan flexousus, Thymus vulgaris, Aloe vera, Tagetes patula, Cordia curassavica, Aegle marmelos, Allium fistulosum, Syzygium aromaticum, and Calotropis gigantea were tested in vitro at 5, 10, and 15% concentrations against Magnaporthe oryzae. Also, two isolates, Bacillus cereus OG2L and B. subtilis OG2A, and one isolate, Azotobacter SAG19, and, similarly, five new generation fungicides were evaluated at three different doses against blast pathogen M. oryzae in vitro. The treatments that exhibited the best performance in vitro were further evaluated against blast disease under field conditions.Results: Extracts of T. patula (5%), C. gigantea (5%), C. curassavica (10%), A. fistulosum (10%), and A. marmelos (15%) showed greater than 81% inhibition to M. oryzae in vitro. Likewise, all three biocontrol agents, viz. B. cereus OG2L, B. subtilis OG2A, and Azotobacter SAG19, demonstrated more than 50% inhibition of mycelial growth of pathogen in vitro, and the commercial formulations of fungicides Propineb, Trifloxystrobin+Tebuconazole, Tebuconazol+Triadimenol, Bacillus subtilis Strain QST 713, and Cinnamon Oil 8%+Clove Oil 2% also significantly inhibited M. oryzae. Under field conditions, C. curassavica (10%), A. marmelos (15%), C. gigantea (5%); B.cereus OG2L; B.subtilis OG2A; Proineb and Trifloxystrobin+Tebuconazole were effective in reducing disease in addition to yield enhancement.Conclusion: Overall, the plant extracts (C. curassavica at 10%, A. marmelos at 15%, C. gigantea at 5%); bio-agents (B. cereus OG2L, B. subtilis OG2A both at 2g/l), and new generation fungicides Antracol 70WP (Proineb) at 2.5 g/l and Nativo 75 WG (Trifloxystrobin+Tebuconazole) at 0.5 g/l provided effective control against blast disease and superior plant growth and yield compared with other treatments and untreated control.
