“…This observation may be attributable to the presence of Aspergillus and other identified mycotoxin-causing organisms in the seed lots of these varieties. This is in consonance with the report by Awuah and Ellis [14], where mouldy groundnut samples were found to contain aflatoxin irrespective of the storage method used. This outcome indicates the potential of packaging and storage methods to inhibit fungal infection and aflatoxin contamination during long-term storage.…”

“…Prior to storage, aflatoxins were detected in four of the varieties studied (Mireku, Adepa, Azivivi, Konkoma); though the presence of aflatoxin-producing fungi such as A. flavus and A. parasiticus in the seed lots was confirmed. Awuah and Ellis [14] made a similar observation when mouldy and pathologically-cleaned samples were both found to have some amount of aflatoxins despite the suspicion that the clean samples in polyethylene storage could inhibit aflatoxin contamination compared to those of the jute bag storage. Dorner et al [25] suggested that percentage fungal infections of groundnut was a poor metric of aflatoxin contamination as this does not indicate the level of growth of the fungus on seeds.…”

“…Post-harvest infection by fungal pathogens and aflatoxin contamination of groundnuts are major constraints to the production of the crop in Ghana. Previously, attempts have been made using plant extracts and other packaging and storage methods to remedy the situation [13,14]. Some level of success has been achieved from earlier studies to evaluate the efficacy of some plant botanicals for storing/preserving shelled groundnuts [13,14].…”

Quality seeds of improved local genotypes is an important input for increasing the productivity of groundnut in Ghana. The existing means of meeting groundnut seed requirements, especially by smallholder farmers, have serious challenges with timely supply and access to these improved genotypes as a result of the limited participation of the private sector and the self-pollinated nature of the crop. Smallholder farmers who take the initiative to store their own seeds, have challenges with storage fungi and aflatoxin contamination. Farmers' groundnut seed stocks have shown that improvement in seed quality and farmers' seed management requires maintaining healthy seed stock. Toxicogenic fungi and mycotoxins have been reported in several human and animal health disorders and are major contaminants of groundnut seeds during storage. Some level of success has, however, been achieved from earlier studies to evaluate the efficacy of some plant botanicals for preserving shelled groundnuts. However, for smallholder on-farm safety, such phyto-based preservation methods rather reduce groundnut seed embryo vigour and germination rates. Designing and developing economically appropriate storage solution (practices) for maintaining seed integrity for use requires evidence-based research and an eco-friendly approach. Thus, this study was aimed at assessing the efficacy of using jute bag (JB) and interlaced polyethylene jute bag (IPJB) combinations for the storage of groundnut seeds (varieties) against fungal infection and aflatoxin contamination under ambient storage conditions.

Fungi and insects infestation of groundnut kernels in storage is a serious post-harvest problem. It leads to quality deterioration and loss of market value and kernels may become contaminated with aflatoxin (AF), which has many negative health implications when consumed. Currently, botanical pesticides are highly preferred to synthetic ones during storage. Effectiveness of preserving groundnut kernels against fungi and insect damage with Syzygium aromaticum cloves (fruits) powder were assessed in the laboratory. Another experiment was conducted under farmer’s storage conditions to evaluate potential of Syzygium powder to protect kernels against AF contamination. In the laboratory assessment, 3 kg kernel samples from sun-dried and undried pods were protected with 2 % (w/w) Syzygium powder. Kernels were kept under ambient conditions in sanitised and non-sanitised rooms for six months during the dry season. Unprotected kernels were kept as control and costs of applying the treatments were estimated. The experiment was repeated in the wet season. Under farmer’s storage, 50 kg kernel lots of 6 and 9 % initial storage moisture contents were protected with 2 % (w/w) Syzygium powder. Kernel lots stored without Syzygium powder served as control. These were packaged in interlaced polypropylene bags (IPPB) or polyethylene bags (PB) and stored in a farmer’s barn on farm. In dry and wet seasons, fungi colonised all kernels stored in laboratory from undried pods completely at three months. Pod drying costs GH¢ 8.99 (GH ¢0.82 = $ US1) and it was cost effective against fungi infection in dry season. Protecting kernels with Syzygium powder was estimated at GH¢ 17.87/100 kg lot and under the humid conditions in wet season, it proved cost effective against fungi infection. However, insect damage to the kernels was always higher after three months. Insects damage and fungi colonisation of kernels packaged in either PB or IPPB were reduced significantly (P < 0.05) at three months storage under farmer’s conditions, when they were protected with Syzygium powder. Aflatoxins do not use abbreviation at beginning of sentence were not detected in the kernels prior to storage. At three months, however, Syzygium-protected kernels had AF levels ranging between 0 and 29.30 µg/kg compared to 27.5-84.0 µg/kg associated with unprotected kernels. Syzygium powder applied at 2 % (w/w) was effective against fungi colonisation, insect infestation and subsequent AF contamination of kernels in storage. However, the kernels should be stored for three months.

استهدفت هذه الدراسة التعرف على تأثير تشميس بذور البازلاء المتحصل عليها من حقول منطقة الوسيطة، الجبل الأخضر ليبيا، والمعزول منها أنواع من فطر Alternaria ، و فطرFusarium، كذلك كل من فطرRhizoctonia ، فطر Botrytis، وفطر Sclerotinia ، عرضت هذه البذور بعد تغطيتها تحت ظروف الصيف لمنطقتي رأس لانوف، وشحات لمدة 5 أسابيع. تشير نتائج البحث إلى أن التعقيم الشمسي مقارنة بغير المغطاة تحت ظروف منطقتي شحات، ورأس لانوف خفضت نسبة ظهور الفطريات المحمولة على البذور، مع عدم وجود فروق بين الموقعين، كانت جميع المعاملات أعلي تأثيرا من الشاهد غير المغطاة، ولم تعطِ النتائج انخفاضا في نسبة إنبات البذور إلا بعد خمسة أسابيع من التغطية، إلا أن نوع الغطاء سجل انخفاضا في طول الريشة للبذور غير المغطاة بالبلاستيك تحت ظروف منطقة شحات، بينما المغطاة بالبلاستيك الأسود كانت أقل تأثرا، وكان الانخفاض معنويا للبذور المغطاة بالبلاستيك الشفاف تحت ظروف منطقة رأس لانوف، وكان للتغطية بالبلاستيك الشفاف تحت ظروف المنطقتين تأثير كبير على طول الجذير، وزاد هذا التأثير زيادة واضحة بمقارنة الأسابيع الخمس. وخلصت هذه الدراسة إلى أن عملية تشميس بذور البازلاء أعطت فاعلية عالية ضد الفطريات المحمولة على البذور في الأسابيع الاولى، دون أن يؤثر على حيويتها.
