“…These results differ with the findings of Mwangi et al [51] and Barasa et al [44] that most farmers in Mwea and Mt Elgon respectively prefer raising their own seedlings. Sources of planting material in this study concurs with those of Testen et al [41]. However, Testen et al [41] did not report on seedling supplier (Commercial seed nurseries) and friends as source of tomato planting materials.…”

“…Up to 40.83% of farmers prefer tomato varieties with good marketability trait led by AEZ LM4 (15%) while 2.5% of farmers preferred tomato variety that is tolerant to pest (Table 3). These findings on the reason for choice of a variety differ with those of Testen et al [41] who reported that variety of tomatoes grown were selected based on fruit size at 60%, disease resistance at 25% and insect resistance at 25%. Our findings also differ with those of Ochilo et al [5] who opined that the tomato varieties grown by the farmers was determined by the cost of seeds.…”

“…Based on these results, it may be concluded that tomato farming in Kirinyaga County is mainly practiced by middle aged individuals. The finding of this study differs with those of Mwangi et al [40] but agree with those of Testen et al [41] and Barasa et al [44] that observed higher numbers of tomato farmers aged between 41-50 years in Tanzania and Mt Elgon in Kenya. However, the results differ with those of Testen et al [41] on participation of age bracket of 18-30 years who were lower in the current study as compared to those aged above 50 years.…”

Lower percentage of youth participating in tomato farming in Kirinyaga County may be attributed to land scarcity and capital as they may not have capital to facilitate farming in addition to not owning land.…”

Diseases are hindrance to tomato production in Kirinyaga County, Kenya. However, information on farmer’s knowledge about tomato diseases to warrant pesticide usage is scanty. Further, there is information gap on disease predisposing factor such as varietal choice and seed source. This study assessed the tomato farmers’ socio characteristic, varieties grown, seed source and knowledge of selected foliar fungal disease among tomato farmers in agro-ecological zones (AEZs) of Kirinyaga County. A cross sectional survey design that in cooperated purposive sampling and snowballing approaches was adopted in the study. Data were collected from 120 tomato farmers using structured questionnaires. A chi square (Ӽ2) test was used to examine the association between different variables at α= 0.05 using SAS version 9.4. No significant association (p > 0.05) was observed between gender of farmers and AEZ. Nonetheless, there were more men (83.33%) than women (16.67%). Terminator F1 variety was popular among farmers (25%). No significance (p > 0.05) association was observed between source of tomato planting material and AEZs. However, Agrovet was a popular seed source among farmers (40%). The reasons for choosing a particular tomato variety was significantly (p < 0.05) associated with the AEZ with 40.83% of farmers preferring tomato varieties with good marketability traits such as fruit size. Farmers’ knowledge of causative agent of early blight, late blight and Septoria leaf spot was significantly (p < 0.05) associated with AEZs. The source of farmer’s knowledge on tomato foliar fungal diseases was not significantly (p > 0.05) associated with AEZ. However, farming experiences was a popular source of knowledge (51.67%) among farmers. Inability of some farmers to identify tomato diseases negates the efforts on disease management in tomato production in Kirinyaga County. Therefore, measures such as coordinated education on tomato diseases is necessary to empower farmers on disease causes and identification to enhance disease management and improve tomato yields in Kirinyaga County in Kenya.

Family farming, crop diversity and traditional knowledge for plant diseases management characterize Ribeira Valley, São Paulo State, Brazil. Our aim was to diagnose the profile of family farmers from Registro, a municipality of Ribeira Valley, and to determine their perception and adoption of integrated plant disease management (IDM). Semi-structured questionnaire was conducted with farmers and data were analyzed by average, median, mode, Pearson's χ2 test and Monte Carlo simulation. Men and women are involved in farming, but men are prevalent (68%). There are few young people (18% were up to 30 years old), reaffirming their exodus from rural activities. These farmers grow and sell vegetable, fruit, medicinal, and ornamental plants, and they exchange information among themselves, with low demand for farm store sellers. Elimination of symptomatic plants is the main control (13% of strategies adopted). Crop residues elimination, crop rotation and resistant plants were also highlighted (12% each one). Most of the respondents did not know IDM concepts, and after the explanation, they agreed that it is possible put into practice. Dialogue between farmers is strategic for them to obtain information, and rural extension is important for the dialogical transmission of knowledge, and for IDM adoption and maintenance in small properties.

Root-knot nematodes (RKN) (Meloidogyne spp.) are among the serious biotic constraints to tomato growers in Tanzania but are relatively overlooked. This required a survey of growers in Mvomero District, Morogoro, Tanzania, to assess their RKN expertise. Semi-structured questionnaires were used to collect data from 100 randomly selected respondents in Mlali (33), Doma (33), and Dakawa (34). Socioeconomic status, RKN awareness, tomato varietals, seed sources, and yield were collected. RKN awareness varied significantly among responder categories. 59% were unaware of RKN. Farming experience correlated with tomato yield, RKN awareness, and RKN-resistant tomato varieties. Rio Grande (14%), Cal J (18%), Roma (10%), and Tanya (16%) were popular tomato types, while hybrids included Imara F1 (19%), Assila F1 (15%), Jarrah F1 (2%), Zara F1 (3%), Kipato F1 (2%) and Anna F1 (2%). Seventy-five root and 75 rhizosphere soil samples were taken from tomato plants at the flowering stage demonstrating stunting, chlorosis, and wilting at least 1km apart in Mlali, Doma, and Dakawa Wards. Samples were shovelled 25 cm deep, packed in sterile plastic bags, labelled, and delivered to Tanzania Agriculural Research Institute Kibaha Nematology laboratory. Results revealed the significant prevalence and incidence of RKN. Despite the occurrence and damage caused by RKN in tomato in the study areas, only one percent of respondents recognized RKN as a serious problem. Awareness campaigns on RKN will facilitate farmers’ consciousness of their existence and management.
