“…Similarly, phytochemical screening studies associated with the species M. ferruginea have shown that they are a rich source of avonoids (iso avonoids, rotenoids, chalcones, and pterocarpans) (Deyou and Jang, 2018; Wang et al, 2020) as well as rotenoids (deguelin, rotenone, and tephrosin) (Choudhury et al, 2015). A study on M. ferruginea leaf solvent extracts against maize weevils, and red our beetles showed a higher percentage of weevils and beetles (> 55%) repellency in all M. ferruginea leaf polar solvent extracts applied at rates of 5 and 10%, at two days after treatment (Hiruy and Getu, 2020). It has been reported that the genus Milletia alone contains more than 25 avonoids, 50 iso avonoids, 12 chalcones, and various compounds, and rotenone is considered one of the foremost active biochemicals in M. ferruginea (Bekele, 2002).…”

Common bean (Phaseolus vulgaris L.) is an essential crop for food security and nutrition mainly for Sub-Saharan African’s smallholder farmers. However, the production and productivity of common bean is mainly constrained by Mexican bean beetles, Zabrotes subfasciatus (Boheman). Thus, the objectives of this study were to evaluate the effectiveness of plant seed powders of neem, Hochst and wild marigold, leaf powders of sweet fennel and broad-leaved croton, plant essential oils of neem and Hochst and African cabbage edible oil at different rates against Z. subfasciatus. All parameters at all botanical seed and leaf powder rates showed a significant difference over the untreated control, except for seed damage at 5 g leaf powders of sweet fennel and broad-leaved croton. Neem, wild marigold, and Hochst at the rates of 5, 10, 15 g/ 150 g, and sweet fennel at 10 and 15 g/ 150 g and broad-leaved croton at 15 g/150 g resulted in 96–100% seed protection, reduced emergence of F1 progeny, seed damage, seed weight loss, and were statistically at par with primphos-methyl. All tested botanical powders recorded 87–100% germination. The botanical oils and mustard cooking oil at rates of 0.5, 1.5, and 3 mL per 150 g common bean produced adult beetle mortality in the range of 93–100% and seed protection of 99–100%. Thus, smallholder farmers can use any of the above indicated botanical powders or oils for post-harvest storage depending on their availability against Z. subfasciatus. Further research on the botanical powders and oils under farmer’s storage condition is important.

“…The maize grain used in the experiment (BH-661 hybrid maize) was cleaned and disinfested by being placed in a deep freezer for two weeks at temperatures ranging from -20 to 0°C to remove internal parasites. To adapt it, it was kept under experimental conditions for two more weeks (Hiruy and Getu, 2020). The maize weevils were obtained from BARC's maize store and grown in the lab.…”

Several maize varieties with high-yield potential have recently been created; however, their resistance to storage pests is unknown. This study compares the resistance ability to Sitophilus zeamais of four open-pollinated varieties (OPVs) and thirteen hybrid maize varieties using Dobie's susceptibility index (SI). The genotypes were tested in a completely randomized design with three replications at a temperature of 28°C and a humidity of 65 to 70%. A resistant OP maize variety (Melkassa 6Q) had SI of less than 3.5 (3.43). OPVs evaluated (Gambela, Gibe 2, and Gibe 3) had SI of 4.60, 5.32, and 6.77, respectively, while most hybrid varieties had SI of 3.82,

“…To avoid crop losses, smallholder farmers in Ethiopia heavily rely on the use of pesticides [5,6,10]. However, pesticides are misused and abused in Ethiopian agriculture, where there are reports of unsafe practices such as the use of cocktails, unrecommended products, incorrect dosage, and frequent application [11,12].…”

“…However, pesticides are misused and abused in Ethiopian agriculture, where there are reports of unsafe practices such as the use of cocktails, unrecommended products, incorrect dosage, and frequent application [11,12]. Unsafe and repeated use of pesticides have resulted in the continuous development of pest resistance in the field and storage [10,13]. This is often the reason why higher amounts and new chemical…”

Pesticide Use Practices among Female Headed Households in the Amhara Region, Ethiopia

2022

Drawing on social practice theory (SPT), we extend our understanding of the existing pesticide use practices among female-headed households (FHHs) in the Amhara region of Ethiopia. We used mixed research methods combining household surveys, focus group discussions (FGDs), key informant interviews, and field observations complemented by photography. A binary logistic regression model was used to investigate the factors that influence the adoption of personal protective equipment (PPE) among FHHs. This finding suggests that pesticide use is an activity consisting of purchasing and using practices with several interacting elements such as materials, competences, and meanings. The main meaning or material element for pesticide purchasing are the perceptions of efficacy on pests, diseases, and weeds (65%), cost and availability in smaller quantities (60.7%), and a woman’s available time and mobility (58.9%). Pesticide hazards to human health or the environment seem not to be relevant for most FHHs. Pesticide use practices among FHHs are done in violation of safety recommendations, motivated by not only material elements (labor, income, time, and the provisioning system), but are notably shaped by competences (skills and knowledge), and meanings (norms, values, rules, and shared ideas). As the regression results show, age and retailers information (p < 0.05) are the significant factors that influence PPE adoption among FHHs. We suggest a change of the practices and processes that sustain women’s lives, a foundational shift of the socioeconomic and cultural environment, and promoting new meanings and competences through advisory services or training.
