“…Training has been reported to improve knowledge and change the farmers' attitude in crop pest management, which leads to the use of proper and safe crop disease management methods (Gautam et al, 2017). Lack of awareness on the course and spreading of rice blast disease reported by the majority of the respondents has also been reported by Adam et al (2015).…”

“…The use of non-recommended pesticides, improper application of pesticides, counterfeit and expired pesticides were among the reasons reported for the persistence of the crop diseases (Ngowi et al, 2007;Nonga et al, 2011;Lahr et al, 2015;Mendesil et al, 2016). Training of farmers enhances adoption of Integrated Pest Management practices (IPM), reduce the quantity of pesticide use, frequency of spraying and the habit of mixing different pesticides (Gautam et al, 2017).…”

The objective of this paper was to investigate farmers’ knowledge and management of rice blast disease in Tanzania. Farmers’ household survey was conducted in five districts namely Mvomero, Morogoro rural, Ulanga, Korogwe and Muheza in April and May 2017. Data were collected through face-to-face interviews using semi-structured questionnaire and observations made through transect walks across selected villages. Farmers observed symptoms of rice blast disease for the first time in the past 3 to 10 years, with higher severity of blast disease in April to May each year. About 46.3% of the respondents were not aware of the cause and spread of rice blast disease. About 39.9% of the respondents associated rice blast disease with drought, high rainfall and temperature (8.7%) and soil fertility problems (5.1%). About 18.7% of the farmers reported burning of crop residues, 17.0% use of ash, 4.0% use of nitrogen fertilizer and 6.3% application of fungicide for management of rice blast disease. The majority (54.0%) of farmers did not apply any management method. Most farmers planted local upland rice varieties, with only 7.7% using improved varieties. About 69.6% of the respondents shared information on disease management among themselves. Lack of knowledge, ability to afford and unavailability of effective blast disease control methods were reported to affect the management of the disease. Strengthening the capacity of farmers to identify the disease and proper management practices will sustainably solve the problem of rice blast disease in upland rice production.

“…There is currently an over‐reliance on synthetic insecticides by farmers to manage insect pests on mango, including fruit flies. Insects are increasingly developing resistance to varying classes of pesticides because of overuse (Vontas et al ., ; Pretty and Bharucha, ; Gautam et al ., ). Furthermore, excessive use of synthetic pesticides has adverse effects on financial returns and human health, as well as on the environment and biodiversity (Rejesus et al ., ; Asfaw et al ., ; Schreinemachers and Tipraqsa, ; Gautam et al ., ).…”

These negative consequences are more severe in developing countries, partly because insecticide regulations are less restrictive than in their developed counterparts, and partly because spraying is often conducted manually, without adequate measures to prevent negative effects on human health and the environment (Ghimire and Woodward, ).…”

We estimate the impacts of a bundle of integrated pest management (IPM) practices on mango yield, mango net income, insecticide use, human health and the environment, using recent household survey data of mango growers in Kenya. We employ a multinomial endogenous switching treatment regression model with an ordered probit selection rule to establish counterfactual outcomes. Our results indicate that IPM-adopting farmers have higher mango yields and mango net income, and also use lower quantities of insecticide and cause less damage to the environment and to human health. In addition, switching from one IPM to multiple IPM practices generates greater economic, environmental and human health benefits. These results suggest intensification of IPM-adoption efforts and encouragement of the use of multiple IPM practices. These positive outcomes could be achieved through greater provision of technical support and extension services to farmers.

“…Typically, the MHM moth lays eggs on emerging panicles (Gahukar et al 1986) and it takes two weeks for the parasitoid progeny to disperse from bags after deployment . This timing coincides with the growth of MHM into third and Though the ability of farmers to describe crop insect pests (Ochou et al 1998;Tefera, 2004;Poubom et al 2005;Abtew et al 2016), including pearl millet insects and the MHM life cycle (Tanzubil and Yakubu 1997;Ba et al 2013), has been well documented in Africa, egg scouting by farmers would require some specific training (Silvie et al 2001;Gautam et al 2017). Also, scouting for eggs could be time consuming.…”

Timing of releases of the parasitoid Habrobracon hebetor and numbers needed in augmentative biological control against the millet head miner Heliocheilus albipunctella

Heliocheilus albipunctella de Joannis (Lepidoptera: Noctuidae) is one of the major insect pests of pearl millet in the Sahel. The native parasitoid, Habrobracon hebetor Say (Hymenoptera: Braconidae), is currently being promoted for augmentative biological control of the pest in the Sahel. The current study was carried out to identify the right time for releases of the parasitoid using either pearl millet growing stage, or pest occurrence as reference, and to determine the optimal number of parasitoids needed to cover a given area. Our results indicate that release of parasitoids at the panicle emergence stage or sixweeks after first sight of eggs of H. albipunctella lead to highest parasitism of H. albipunctella larvae by H.hebetor. The dose of 800 parasitoids for a distance of 3 km radius was enough for controlling H. albipunctella. The implications of the results are discussed toward cost effective and practical recommendation adapted to the Sahelian conditions.
