“…Growing beans can improve the soil properties and reduce the nitrogen fertilization due to the plant’s characteristic of N-fixation, which increases the soil fertility [ 4 ]. However, its production faces many challenges, including pests and diseases, that are related to various bacteria [ 5 , 6 ], fungi [ 1 ], nematodes and insects [ 7 ], as well as abiotic stresses, e.g., salinity [ 8 ], drought [ 9 ], and heat [ 10 ]. Losses in productivity and quality have commonly reached as high as 60% due to biotic and abiotic stresses [ 9 ].…”

Nanofungicides with Selenium and Silicon Can Boost the Growth and Yield of Common Bean (Phaseolus vulgaris L.) and Control Alternaria Leaf Spot Disease

There is an urgent need to reduce the intensive use of chemical fungicides due to their potential damage to human health and the environment. The current study investigated whether nano-selenium (nano-Se) and nano-silica (nano-SiO2) could be used against the leaf spot disease caused by Alternaria alternata in a common bean (Phaseolus vulgaris L.). The engineered Se and SiO2 nanoparticles were compared to a traditional fungicide and a negative control with no treatment, and experiments were repeated during two successive seasons in fields and in vitro. The in vitro study showed that 100 ppm nano-Se had an efficacy rate of 85.1% on A. alternata mycelial growth, followed by the combined applications (Se + SiO2 at half doses) with an efficacy rate of 77.8%. The field study showed that nano-Se and the combined application of nano-Se and nano-SiO2 significantly decreased the disease severity of A. alternata. There were no significant differences among nano-Se, the combined application, and the fungicide treatment (positive control). As compared to the negative control (no treatment), leaf weight increased by 38.3%, the number of leaves per plant by 25.7%, chlorophyll A by 24%, chlorophyll B by 17.5%, and total dry seed yield by 30%. In addition, nano-Se significantly increased the enzymatic capacity (i.e., CAT, POX, PPO) and antioxidant activity in the leaves. Our current study is the first to report that the selected nano-minerals are real alternatives to chemical fungicides for controlling A. alternata in common beans. This work suggests the potential of nanoparticles as alternatives to fungicides. Further studies are needed to better understand the mechanisms and how different nano-materials could be used against phytopathogens.

Youth transition in the common bean (Phaseolus vulgaris L.) value chain remains low in Ghana and Cameroon despite the potential of the bean sub-sector in reducing poverty, unemployment, and undernutrition. This study compared youth transition in the bean value chain in Ghana and Cameroon. It investigated how intersectional elements, including age, influence the uptake of bean production among the youth in these two countries. Data were collected from 266 participants from Ghana and 84 from Cameroon. The data were collected through focus group discussions (FGD) and in-depth interviews. The results demonstrated that Ghanaian youth disfavored bean production, while in Cameroon, youth favored bean production. In both cases, parents were instrumental in influencing youth choices. In Ghana, many parents did not approve of their children taking bean production as a primary occupation. By contrast, parents in Cameroon favored bean production and appeared to value agriculture, thus encouraging their children to venture into it. Despite the differences in Ghanaian and Cameroonian youth’ perceptions of agriculture, the challenges they faced that hindered their participation in the bean value chain remained the same: lack of financial support, limited access to land, and lack of technical know-how.
