“…e Ministry of Agriculture Livestock and Fisheries [7,57] reported that it is not possible to completely remove all foreign seeds due to the high cost of sorting and selection. However, Bishaw et al [58] reported that farmers do use local selection, treatment, cleaning, and storage to maintain the quality status of their farm-saved seeds. Additionally, seed storage heavily affects the plant quality [59].…”

Over 80% of farmers in the developing countries use seeds from the informal seed supply that is of unknown quality status with low physical purity, reduced vigour, and contamination with seed-borne pathogens. A survey involving 114 farmers was conducted in Makueni and Taita counties using a semistructured questionnaire to determine cowpea production practices. Forty-seven cowpea seed samples were collected from farmers, and thirty-four were collected from markets and analysed for physical and physiological quality. The data from the questionnaire were analysed using SPSS package. Majority, over 76% of farmers used farm-saved seeds and intercropped cowpea with cereals (56%). The common storage container was polythene bags (56%), and farmers did not treat the seeds. The seed was below the recommended purity standard of 98%. In Taita, farm-saved and market-sourced seeds met the recommended 75% germination at 82.7% and 76.8%, respectively. Even though the germination standard was met, seeds were of low physical purity and reduced vigour. Farmers should be enlightened on recommended production practices, methods of harvesting, and postharvest handling practices to reduce seed quality loss during storage and maximize production.

“…Serious disease outbreaks are the results of seed dissemination of plant pathogens. Infected seeds affect the grain yield and quality by producing abnormal seedlings and lower germination (Bishaw et al, 2013). Seed borne fungi are responsible for seedling damage, seed rot, seed abortion and cause the systemic or local infection (Ryley et al, 1989).…”

A B S T R A C TWheat and chickpea are considered the most important sources of food and energy and stored for longer period of time in the rural areas in the farmers sheds as seed for the next crop and as market commodity to sale. Both of these crops are liable to many mycoflora which not only deteriorate their quality but also leads toward the crop failure during the coming season. A number of seed borne pathogens viz., Aspergills niger, Aspergillus flavus, Aspergillus sulphureus, Aspergillus nidulense, Rhizopus stolonifer, Penicillium spp. and Drechslera spp, were isolated from wheat seed samples while Aspergillus niger, Aspergillus flavus, Bipolaris spp., Penicillium spp. and Rhizopus stolonifer were isolated from seed samples of chickpea. Various broad spectrum fungicides were evaluated against the isolated mycoflora which showed significant result. Score, Topsin-M and ridomil gold to be the most significant fungicides at all doses against the isolated mycoflora.

“…Numerous examples exist in agriculture literature for the international spread of plant diseases as a result of importation of seeds that were infected or contaminated with pathogens (Clear and Patrick, 1993). The study of seed-borne pathogens is necessary to determine seed health and to improve germination potential of seed which finally leads to increase of the crop production (Bishaw et al, 2013). Fungi are the principal pathogen organisms associated with crop seeds.…”

One hundred wheat (Triticum aestivum L.) accessions were selected on the basis of different geographical areas of Pakistan. Isolation and identification of seed born fungi were conducted according to standard blotter test and a total of five major seed borne fungi including Alternaria alternata, Aspergillus niger, Fusarium species, Drechslera species and Phytophthora species were isolated from the wheat seeds. The frequency of occurrence of these five seed born fungi was 49, 46, 42, 35, and 16%, respectively. Infection percentage varied from 0 to 90% in all 100 wheat accessions. Among the accessions, the highest infection (100%) of seed born fungi was recorded in 011185 and 011757 accessions while the lowest infection (10%) was recorded in 011415 accessions. Moreover, in accessions collected from Gilgit Baltistan and Azad Jammu Kashmir. Alternaria niger and Alternaria fusarium were dominant, while in Khyber Pakhtunkhawa province, A. niger was prevalent followed by A. alternata. In the case of Baluchistan province, the dominant seed born fungi was A. alternata followed by Drechslera spp. Similarly, in case of Punjab, the occurrence of A. alternata, Drechslera spp., Fusarium spp., and A. niger associated with seeds were similar. For accession collected from Sindh province, the dominant seed born fungi was A. niger and Drechslera spp. However, the Phytophthora spp. infection of wheat seeds accession of Baluchistan was the highest followed by wheat seeds accession collected from Gilgit Baltistan and AJK, Kpk and Punjab, whereas wheat seeds accessions collected from Sindh province were found to be free from Phytophthora spp.
