Vermicompost Tea

Field trial experiment was conducted at the premise of Nepal Academy of Science and Technology during rainy season (April-June) in 2004 under the rainfed condition. In this study, four types of compost tea: aerated vermicompost tea (ACTV), non aerated vermicompost tea (NCTV), aerated compost tea (ACTC) and non aerated compost tea (NCTV) was prepared and investigated for the suppression of Foot rot disease of Rice caused by Fusarium moniliforme Sheldon - Gibberella fujikuroi. The result was compared with carbendazium (2.5 g per kg dry seeds) treatment and water check. And data was analyzed using one way ANOVA. Among these four compost tea, ACTV showed statistically significant maximum control (25.6% increment of healthy seedlings), followed by ACTC (22.4% increment of healthy seedlings). Least effect was obtained by NCTC (13.6% increment of healthy seedlings). It was observed that 18% of collected Khumal-4 variety rice was infected with Fusarium monoliforme as revealed by Standard Moist Blotter Technique. In concurrence with field trial experiment, treatment of the rice seeds in the Standard Blotter Technique with compost tea revealed highest efficiency of ACTV in reducing the number of affected seeds (12% reduction in affected seeds) followed by ACTC (10% reduction) and NCTV (8% reduction). NCTC were found to be least effective (6% reduction) among the four types of compost tea. Application of compost tea also increases the percentage of germination of seeds, with maximum effect obtained by ACTV (98%).

Fusarium moniliforme is one of the important seed-borne fungi responsible for foot rot disease in rice. The study was conducted at the Plant Pathology Division of NARC, Khumaltar from July- December 2019 to find out the level of seed infection of F. moniliforme in different varieties of rice from mid-hills of Nepal. A total of 20 seed samples of different varieties of rice with 240 seeds of each sample were tested following a deep-freeze blotter method distributing 80 seeds per replication and maintaining 3 replications. Seed to seedling transmission test was carried out under screen house conditions. Two hundred seeds of each highly infected five varieties from laboratory test data were planted in eight pots, twenty-five seeds per pot, and categorized into four replications. Component plating was done to determine the location of F. moniliforme infection in a seed. Data analysis was done using STAR at a 5% level of significance. There was a significant difference among all the varieties. The highest incidence of F. moniliforme infection was found in seeds of Khumal-9 variety and lowest in Fan-10 variety. From seed to seedling transmission test, Khumal-4 variety was found highly susceptible to foot rot among the 5 varieties planted. Transmission percentage of disease from seed to seedling was found ranging from 16.19-72.31%. Equally, Component plating concludes that seed coat, as well as endosperm, was the location of F. moniliforme infection in rice seed. Foot rot being one of the serious diseases of rice at present time researches should be done more on this for its effective management and control. Seed health status testification before taking seeds to the field should be done so that timely control like seed treatment could be applied to control the outbreak of the disease in the field.

Abstract We constructed a recombination-based map of the fungal plant pathogen Gibberella fujikuroi mating population A (asexual stage Fusarium moniliforme). The map is based on the segregation of 142 restriction fragment length polymorphism (RFLP) markers, two auxotrophic genes (arg1, nic1), mating type (matA+ / matA−), female sterility (ste1), spore-killer (Sk), and a gene governing the production of the mycotoxin fumonisin B1 (fum1) among 121 random ascospore progeny from a single cross. We identified 12 linkage groups corresponding to the 12 chromosome-sized DNAs previously observed in contour-clamped homogeneous electric field (CHEF) gels. Linkage groups and chromosomes were correlated via Southern blots between appropriate RFLP markers and the CHEF gels. Eleven of the 12 chromosomes are meiotically stable, but the 12th (and smallest) is subject to deletions in 3% (4/121) of the progeny. Positive chiasma interference occurred on five of the 12 chromosomes, and nine of the 12 chromosomes averaged more than one crossover per chromosome. The average kb/cM ratio in this cross is ~32.

This research is aimed to find out the preference of cocoa pod borer to diameter, biophysical, and biochemistry cocoa pod; the percentage of infested pods, percentage of seed damaged, and percentage of yield lost. In addition, this research is also aimed to assess the effect of plastic thickness on cacao pod rot disease, the effect of sheathing on the black ant and mealybug populations on pods. This research was conducted at Selemadeg District, Tabanan Regency from October 2009 until January 2010. The field trial was arranged into randomized complete block design (RCBD) by 15 treatments were sheathing with various thickness of plastics (S0-S4) and cocoa pod diameters (B1-B3). The results indicated that, based on the percentage of the infested pod, cocoa pod borer has preferred the fruit with diameter > 4.5-7.5 cm. This condition may be contrasted, the smallest pod size (3,5-4,5 cm) was the healthiest pod, even though it contains more nutritionally compound. The smaller pod rot disease in red and green types. Sheathing by plastic of > 0.02 mm thick in medium size of pods was the most effective to prevent cocoa pod borer infestation. Sheathing with plastic was not affecting the population of both black ants and mealy bugs. Based on these results, it can be suggested that sheathing with plastic of > 0.02 mm thick on medium size of the pod is promising control measure to prevent yield lost caused by cocoa pod borer and cocoa pot rot disease.
