    How does IPM 3.0 look like (and why do we need it in Africa)?
    Tamo, Manuele; Glitho, Isabelle; Tepa-Yotto, Ghislain; Muniappan, Rangaswamy (Elsevier, 2022-10)
    The concept of Integrated Pest Management (IPM) was introduced sixty years ago to curb the overuse of agricultural pesticides, whereby its simplest version (IPM 1.0) was aiming at reducing the frequency of applications. Gradually, agro-ecological principles, such as biological control and habitat management, were included in IPM 2.0. However, throughout this time, smallholder farmers did not improve their decision -making skills and continue to use hazardous pesticides as their first control option. We are therefore proposing a new paradigm - IPM 3.0 - anchored on 3 pillars: 1) real-time farmer access to decision-making, 2) pest-management options relying on science-driven and nature-based approaches, and 3) the integration of genomic approaches, biopesticides, and habitat -management practices. We are convinced that this new paradigm based on technological advances, involvement of youth, gender-responsiveness, and climate resilience will be a game changer. However, this can only become effective through redeployment of public funding and stronger policy support.

    IPM for tropical crops: lentil
    Sharma, Anamika; Muniappan, Rangaswamy (CABI, 2021)
    Lentil is an old-world legume and grown in more than 70 countries. It is a major source of protein in plant-based diets and is often used to fix nitrogen in the soil as a rotational crop, especially with cereal crops. Canada, USA, and Australia are the major exporters of lentil. Around the globe, this crop faces various biotic and abiotic stresses. More than 35 insect pests and the same number of diseases are reported to infest lentil in different parts of the world. While the status of insect pests and diseases varies in different geographical regions, some of them are aphids, armyworm, cutworm, pod borer, Stemphylium blight, fusarium wilt, Alternaria blight, and rust. Cultural management strategies for abiotic and biotic stresses include crop rotation, the timing of seeding, appropriate seed rates, and weed management. Biological control agents are also known for several insect pests. Environmental-friendly options such as biopesticides and microbials (entomopathogenic bacteria, fungi and nematodes, neem products, and Trichoderma sp.) can be used as seed treatment and foliar application. Various tolerant and resistant lentil varieties are available around the globe. In the present article, we provide an IPM package for the management of major biotic stresses for lentil crop.
