“…Twelve fungal species were isolated and identified with blotter method while twenty were obtained by agar plate method. These results were in coherence with those of many research groups around the world (Imolehin, 1987;Khan et al, 1988Khan et al, , 2000Kim and Lee, 1989;Odebunmi, 1989;Wahid et al, 1993;Javaid et al, 2002, Ibiam et al, 2006. Many of the isolated fungi have been reported to be associated with seeds of other crops (Tsopmbeng, 1994;Tsopmbeng and Fomengia, 2015).…”

“…Seed health testing procedure involves techniques, such as direct examination of dry seeds, examination of germinated seeds, examination of organism removed by washing and examination after incubation (both blotter and agar plates). Ibiam et al [6] and Ito et al [7] observed that some fungi pathogens borne on rice seeds are better deleted by using different seed health testing techniques. According to their observation, using blotter, agar plate and deep freezing techniques, the blotter method was found suitable for the detection of Alternaria alternate, A. tenuissima, Aspergillus niger, A. flavus, A. terreus, Chaetomium globosum and Curvularia spp.…”

“…were isolated more on agar plate and Fusarium spp., Trichoconis padwickii, Myrothecium roridum were detected more where deep freezing technique was used. Also, several fungal pathogens have been isolated from rice and have been reported to be responsible for a number of disease right from nursery to the field [6,8]. Also, Ora et al [3] reported that in a study carried out in Punjab, Pakistan on the mycoflora of stored rice grains, some fungi pathogens were isolated.…”

This study was conducted to assess the incidence of seed-borne fungi on rice seeds sourced from the major rice growing areas of SouthEastern Nigeria. The rice seeds were collected during the dry seasons between 2009 and 2010. Four hundred rice seeds randomly collected and surface sterilized by washing in 3% sodium hypochlorite and rinsed two times with sterile distilled water were placed in three circular rings inside the Petri dishes. The incubation was done one after the other for each variety from all the locations. Ten fungi species from eight genera were isolated from the rice seeds in all the rice growing areas of SouthEastern Nigeria. The fungi pathogens vary from one locality to another, as well as the frequency of occurrence. The pathogens isolated include: Fusarium moniliforme, F. solani, F. oxysporium, Aspergillus spp., Botridiploidia spp., Helminthosporium spp., Penicillium spp., Trichoconis padwickii, Curvularia oryzae and Phoma oryzae. Though, there was the presence of some seed-borne fungi in the rice seeds from the areas studied, most of the cultivars experienced up to 90% germination. But some cultivars had very low germination. IR 1416 from Arochukwu and GB90 from Arondiuzogu had less than 1% germination. This study shows that seed-borne organisms are major constraint in rice production in the SouthEastern states of Nigeria as a result of low seed germination stemmed from infestation of fungi organisms in the seeds.

“…The global rice production is estimated at 454.6 million tonnes annually which has an average yield of 4.25 tonnes per hectare (Fazlollah et al, 2011). Land under rice cultivation in Nigeria has increased from 1,609,890 ha in 2005/2006 to 2,012,740 ha in 2009/2010, while production has also moved from 3,286,500 kg/ha in 2005/2006to 4,080,940 kg/ha in 2009/2010(Ibrahim, 2013. low quality.…”

Sixty rice accessions were assessed in the field for resistance to Aspavia armigera F. attack under natural and artificial infestations. Out of these, 30 were lowland and 19 upland varieties derived from the International Institute for Tropical Agriculture (IITA) breeding programmes, while the others were obtained from other local and international organizations. From the upland varieties, the highest population density of A. armigera was recorded on CAN 4143 (p < 0.05), while the highest percentages of unfilled grains were obtained on ITA 132 (33.1%) and CAN 4143 (32%), and were both rated the most susceptible to A. armigera. CAN 6656, on which the lowest value for unfilled grains (4.7%) was found was rated resistant. Among the lowland varieties, TOX 3118-2-E2-2-1-2, on which was recorded the highest population density of A. armigera and highest percentage of unfilled grains (p < 0.05) was considered susceptible, while ITA 230, ITA 308, ITA 123, TOX 3100-32-2-1-3-5, TOX 3107-39-1-2-1-3, TOX 3027-43-1-E3-1-1, TOX 3441-7-1-1-1, TOX 3226-5-2-2-2, TOX 3716-15-1-1 and TOX 3561-56-2-3-2 were considered resistant. However, no-choice tests revealed that five from each of ten upland and lowland varieties initially rated as resistant were severely damaged. The other five upland ITA 315, IRAT 169, ITA 321, FAROX 41 and M 55 with consistent expression of resistance which also had low number of stylet sheath: 11, 17, 23, 24.3, and 29.3, respectively, were therefore rated resistant. Similarly, lowland ITA 230, TOX 3561-56-2-3-2, TOX 3100-2-1-3-5, TOX 3226-5-2-2-2 and TOX 3107-39-1-2-1-3 with low number of stylet sheath were rated resistant as well.
