“…High coinfection of CMV with PVMV and PeVYV was also detected, which confirms our previous findings (Zohoungbogbo et al 2022). Previously, Polerovirus (PeVYV) has been found in association with Waweru et al 2020aWaweru et al , 2021. Only aphidtrasmitted viruses were detected in our study and were prevalent across all the AEZs.…”

“…In contrast, companion cropping could have negative consequences for famers, as some of the crops used are also hosts for the arthropod vectors and contribute to the distribution and maintenance of viral diseases at pepper production sites (Ateka et al 2017;Jacobson et al 2018;Kenyon et al 2014;Nadeem et al 2015;Saethre et al 2011). It has been suggested to train farmers on the benefits of biopesticides and companion cropping to further promote their use (Nyangau et al 2022;Waweru et al 2021).…”

“…The strategies employed and recommended for virus control are essentially based on the management of the vector. Good cultural practices include the appropriate selection of production site (far from potential sources of the virus); production of pepper in association with crops such as plantain (Musa ×paradisiaca L.), cassava (Manihot esculenta Crantz), sorghum [Sorghum bicolor (L.) Moench], or maize (Zea mays L.) to control vectors such as aphids (Fajinmi and Odebode 2010;Waweru et al 2021); and to apply adequate organic matter (Fajinmi and Odebode 2007). found that aqueous extracts of garlic (Allium sativum L.), hyptis (Hyptis sp.…”

Pepper (Capsicum spp.) is an important solanaceous cash crop in Benin; however, productivity is limited due to several key constraints, especially diseases caused by viruses. We sought to understand farmers’ perceptions of viral diseases, management strategies deployed, and to identify the virus population affecting pepper production in Benin. To assess farmers’ perceptions and management of viral diseases, a survey was carried out in four agroecological zones of Benin. A total of 144 pepper farmers were interviewed using the snowball method. A total of 52 pepper leaf samples with virus-like symptoms were collected and diagnosed by reverse-transcriptase polymerase chain reaction (RT-PCR) or PCR. Pepper production systems varied across agroecological zones (P ≤ 0.001) with a predominance of farms practicing monoculture (82%). The majority of farmers (89%) indicated that pests and diseases were the main constraints to increased production. Cucumber mosaic virus (92% of the total samples), Pepper vein yellow virus (52%), and Pepper veinal mottle virus (50%) were the major viruses detected in pepper fields in Benin. There were both single (29%) and mixed (71%) infections of the viruses, suggesting that mixed infections are common for pepper in Benin, confounding efforts to reduce virus infections. Nearly 100% of the farmers surveyed were not aware of these viral diseases. They also could not directly relate symptoms of virus infection to the presence of aphids, whiteflies, or thrips. Farmers relied primarily on synthetic insecticides (93%) to control virus vectors. Interestingly, some farmers applied commercial (12%) and homemade (17%) biopesticides, with neem-based preparations being the most widely used. A total of 15% of farmers used companion cropping with maize, mint or basil and 43% of farmers used crop rotation as a cultural management practice to control viral disease and vector pressure in pepper fields. The implications of this work include the importance of training farmers and extension agents on diagnosis of viruses and their vectors causing viral diseases. This study provides baseline information for the development of host-resistant cultivars and deployment of integrated pest management strategies for pepper in Benin to reduce farmer losses.

“…Still, the four crops' effects differ when used as barrier crops. Barrier crops can affect the main crops by intercepting, arresting, or retaining pests, thereby limiting the number of insect pests and insect vectors reaching the main crop, which eventually reduces the incidence of viral disease (Waweru et al, 2021). In this experiment, basil can significantly reduce the disease incidence and severity to 72.42% and 72.83%, respectively (Table 3).…”

An experiment is conducted to investigate the effects of cultural techniques on pepper yellow leaf curl disease caused by Pepper yellow leaf curl Indonesia virus (PepYLCIV). The investigation is conducted in the area where the disease has been endemic and Bemisia tabaci is abundant. Four cultural techniques are applied in separate lands and cannot interfere with each other. The methods applied are seed treatment, intercropping, trap cropping, and physical barrier. Seeds harvested from infected plants are used for seed treatment experiments, and local farmers use commercial sources for other experiments. The results confirmed that PepYLCIV was a seed-borne virus affected by hot water treatment at 65oC for 30 minutes. Turmeric crude extract could reduce the incidence and severity of the disease. The tomato is a better intercrop than eggplant, mung bean, and soybean in reducing disease incidence, but their effects on disease severity and yield reduction were not significantly different. Basil and marigolds were better barrier crops compared to cosmos and zinnia. A 125 cm high physical barrier using 50 mesh cheesecloth could reduce the disease incidence, but not the lower ones. Under different cultural techniques, PepYLCIV causes a 40.00–52.32% chili yield reduction.

“…The creation of spatial discontinuities relies on non-host plant diversification within (intercropping) or around the field (barrier crop). These plant diversification strategies have been shown to reduce virus spread through a bottom-up regulation of vector populations (Waweru et al 2021;Grauby et al 2022). When vectors are searching for a new host, mixed cropping with non-host plants or tall non-host cover crop around the field could constitute physical barriers and causes vector confusion due to non-host plant chemical cues (Xu et al 2017) which can lower vector incidence and reduce the period they spend on host plants (Alvarez-Baca et al 2022).…”
