As a botanist, in Agribusiness and Sustainable Agriculture I will always recommend the use of botanicals ( Use of medicinal plants which have be tested and proven to be effective against vegetables pests). I personally research and wrote my first bachelor thesis on use of Neem( leaves, bark and seeds) to pests affecting Ugu leaves (Telfaria occidentalis); a popular Igbo vegetable used in making different soup delicacy in South-Eastern part of Nigeria. I also experimented with Neem & peper seeds and; by pouring some into a sac of black eye peas (beans) which were for long term storage. After 6 months, no weevil were found. Some people in the suburbs also stated that for a longer period of time same result were observed.

Biological Controls: A Sustainable Pest Management Solution - Utilizes natural predators or parasites to manage pest populations - Introduces beneficial organisms like ladybugs (aphid control) or parasitic wasps (caterpillar control) - Works within the farm's ecosystem to reduce pest numbers without chemical insecticides - May take longer to see results compared to chemical methods - Enhances biodiversity and reduces reliance on synthetic products - A cornerstone of sustainable pest management This approach promotes a balanced and healthy ecosystem, minimizing harm to non-target species and the environment. By embracing biological controls, farmers can adopt a more sustainable and environmentally friendly approach to pest management.

Botanical Insecticides: A Natural Pest Control Option - Derived from plants with insect-repellent properties - Examples: Neem oil (growth regulator, repellent, antifeedant) - Biodegradable and less toxic to non-target organisms - Favored by sustainable agriculture farmers - Important: responsible use necessary to avoid adverse effects Botanical insecticides offer a natural and sustainable approach to pest management, aligning with environmentally friendly farming practices. However, it's crucial to use them judiciously and follow recommended guidelines to ensure their efficacy and safety.

Botanical insecticides are crucial for sustainable agriculture, offering eco-friendly alternatives to synthetic chemicals. Derived from plants, they are biodegradable, less toxic to non-target organisms, and help manage pest resistance. Key botanical insecticides include neem oil (effective against aphids, whiteflies, and caterpillars), pyrethrins (from chrysanthemums, affecting pest nervous systems), rotenone (from tropical roots, effective against leaf-eaters), garlic and onion extracts (repel pests by masking plant scents), capsaicin (from hot peppers, deters pests with its pungency), and essential oils like peppermint and rosemary (insecticidal and repellent). These should be part of an IPM

Botanical insecticides offer a natural alternative to synthetic chemicals, derived from plants with insecticidal properties. These products, such as neem oil, pyrethrins from chrysanthemum flowers, and rotenone from certain legumes, disrupt pests' biological functions while being less toxic to non-target organisms, including beneficial insects, humans, and wildlife. Botanical insecticides are biodegradable and leave minimal residues, making them ideal for integrated pest management systems that aim to reduce environmental impact. Moreover, their diverse modes of action can help prevent the development of pest resistance, ensuring long-term efficacy.

Tipos de plaguicidas microbianos: Bacterias: Algunas bacterias, como Bacillus thuringiensis (Bt), son letales para ciertos insectos cuando los ingieren. Hongos: Los hongos como Beauveria bassiana y Metarhizium anisopliae parasitan y matan insectos. Virus: Algunos virus, como el virus de la nucleopoliedrosis del granulovirus (NPV), son específicos para ciertos insectos y pueden causar su muerte. Nematodos: Los nematodos entomopatógenos, como Steinernema carpocapsae, se alimentan de insectos y los matan.

Microbial pesticides are vital for sustainable agriculture due to their targeted and eco-friendly nature. Key examples include Bacillus thuringiensis (Bt), which targets specific insect larvae, and Beauveria bassiana, a fungus that infects and kills pests like whiteflies and beetles. Metarhizium anisopliae similarly targets insects, while Trichoderma spp. combats plant pathogens, enhancing soil health. Nucleopolyhedroviruses (NPVs) and Granuloviruses (GVs) specifically target insect larvae. Advantages include environmental safety, target specificity, and resistance management, though challenges like shelf life, application timing, and cost exist.

Microbial pesticides harness naturally occurring microorganisms, including bacteria, fungi, viruses, and protozoa, to control pests. For instance, Bacillus thuringiensis (Bt) is a widely used bacterial pesticide effective against caterpillars, beetles, and mosquitoes. Similarly, fungal products like Beauveria bassiana and Metarhizium anisopliae infect and kill a variety of insect pests. These microbial agents are highly specific, targeting only the pest species while sparing beneficial insects and other non-target organisms. The use of microbial pesticides aligns well with sustainable agriculture goals by reducing chemical residues in the environment and promoting a healthier agroecosystem.

Insect Growth Regulators (IGRs): A Targeted Approach to Pest Control - Mimic hormones in young insects, disrupting development and preventing maturity - Target specific life stages of pests, minimizing harm to beneficial insects and non-target organisms - Useful in sustainable agriculture and Integrated Pest Management (IPM) programs - Contribute to long-term pest control strategies IGRs offer a precise and effective way to manage pest populations, reducing the risk of harm to beneficial insects and the environment. By incorporating IGRs into a comprehensive IPM plan, farmers can adopt a more sustainable and resilient approach to pest management.

Insect growth regulators (IGRs) are effective and eco-friendly pest control products ideal for sustainable agriculture. They disrupt insect development and reproductive cycles, making them targeted and less harmful than traditional pesticides. Key IGRs include: - Methoprene: Mimics juvenile hormone, preventing larvae from maturing. - Pyriproxyfen: Effective against whiteflies, scales, and mosquitoes, with low toxicity to beneficial insects. - Diflubenzuron: Inhibits chitin synthesis, specific to insect pests. - Tebufenozide: Triggers premature molting in caterpillars.

Insect growth regulators (IGRs) are unique in their approach, interfering with the development and reproduction of pests rather than killing them outright. Products containing IGRs, such as methoprene and pyriproxyfen, mimic or inhibit the hormones responsible for insect growth, molting, and maturation. This disruption results in abnormal development, sterility, or death, effectively controlling pest populations over time. IGRs are particularly useful in integrated pest management (IPM) programs because they are highly specific to pest species, reducing the risk to beneficial insects and the environment. By targeting the life cycle stages of pests, IGRs help manage resistance and provide a sustainable pest control solution.

Cultural practices are the only way to approach pest control with minimal resource availability infringement. It involves manipulating farming systems to create an environment that naturally deprives the pests of good living hence leading to their movement to other regions.

Cultural practices involve modifying farming techniques to reduce pest habitat and food sources, thereby preventing pest infestations. Crop rotation, intercropping, and the use of cover crops can disrupt pest life cycles and enhance soil health. Planting pest-resistant crop varieties and adjusting planting times to avoid peak pest periods are also effective strategies. Additionally, maintaining field hygiene by removing crop residues and practicing proper irrigation and drainage can minimize pest breeding grounds. Cultural practices emphasize the importance of creating an unfavorable environment for pests, thereby reducing the reliance on chemical interventions and promoting long-term agricultural sustainability.

Physical barriers are a proactive method to prevent pests from reaching crops, using materials and structures that create physical obstacles. Row covers, insect netting, and mulches are commonly employed to protect plants from insect pests, while also offering the added benefits of microclimate control and weed suppression. Traps and pheromone-based attractants can monitor and reduce pest populations by luring them away from crops. These barriers and traps can be tailored to specific pest threats, providing a targeted and environmentally friendly approach to pest management.

Integrated pest management, IPM. 1. Cultural practices. 2. Mechanical practices 3. Biological, where feasible Chemicals should be a last option.

Being a plant breeder, I would add host plant resistance as an added “method”. Even though, developing varieties with multiple resistances is a long process, it has been proven with GMOs, that it can be done. The only caveat is the eternal question as to what are the effects in the long term of these varieties. Nonetheless, it has to be site specific . The beauty of it is, that when combined with some of the other methods can prove to be a winning combination!

The best option, in my experience, is a combination of cultural and biological practices to control insect pests, but when the pressure is high, chemicals must be used.

Pest control often relies on pesticides, which can negatively impact beneficial insects like bees, ladybugs, lacewings, hoverflies, parasitic wasps, and ground beetles. These insects play crucial roles in pollination and natural pest management. To protect these beneficial species, it's advisable to use Integrated Pest Management (IPM). IPM is a comprehensive approach that combines various strategies—cultural, biological, physical, chemical, and genetic—to manage pests in an effective, economical, and environmentally friendly way. This method aims to minimize economic damage from pests while preserving beneficial insect populations.
