Various definitions concepts historically currently used various pesticide are also described. This review demonstrates that technological advances have sparked renewed research interest in optimization conventional such as aerosols, sprays, fumigants, inert gases. Insect growth regulators/disruptors (IGRs/IGDs) increasingly employed baits, residual treatments, spray-residual protectants long-term stored-grain protection.

Status and Prospects of Botanical Biopesticides in Europe and Mediterranean Countries

Biomolecules, Journal Year: 2022, Volume and Issue: 12(2), P. 311 - 311

Published: Feb. 15, 2022

Concerning human and environmental health, safe alternatives to synthetic pesticides are urgently needed. Many of the currently used not authorized for application in organic agriculture. In addition, developed resistances various pests against classical necessitate urgent demand efficient products with novel modes action. Botanical assumed be effective crop pests, they easily biodegradable available high quantities at a reasonable cost. them may act by diverse yet unexplored mechanisms It is therefore surprising that only few plant species have been commercial usage as biopesticides. This article reviews status botanical pesticides, especially Europe Mediterranean countries, deepening their active principles Moreover, some constraints challenges development biopesticides highlighted.

Assessment of potential biopesticide options for managing fall armyworm (Spodoptera frugiperda) in Africa

Journal of Applied Entomology, Journal Year: 2018, Volume and Issue: 142(9), P. 805 - 819

Abstract The fall armyworm ( FAW , Spodoptera frugiperda ) originates from the tropical and sub‐tropical regions of Americas. Recently it was reported for first time in Africa has since spread rapidly across more than 30 countries continent. Chemical pesticides are being promoted used management, but where application practices and/or active ingredients unsafe there is a need to make effective, low‐risk products available. Given that biopesticides such as microbials microbial extracts, macrobials semiochemicals generally considered be lower risk options pest they promising avenue exploration. When conjunction with good crop can help keep levels under control, reducing apply other pesticides. This study provides basis designing interventions widely available control Africa. It summarizes assessments registered countries, 11 's native range 19 report identifies biopesticide AI which use against an assessment how appropriate these will by smallholder farmers For each identified, detailed profiles were developed covered efficacy ; human health environmental hazards associated agronomic sustainability whether or not practical use.

Bioactivity of Common Pesticidal Plants on Fall Armyworm Larvae (Spodoptera frugiperda)

Plants, Journal Year: 2020, Volume and Issue: 9(1), P. 112 - 112

Published: Jan. 15, 2020

The fall armyworm (FAW), Spodoptera frugiperda (Lepidoptera: Noctuidae) is a recent invasive pest species that has successfully established across sub-Saharan Africa where it continues to disrupt agriculture, particularly smallholder cereal production. Management of FAW in its native range the Americas led development resistance many commercial pesticides before arrival Africa. Pesticide use may therefore be ineffective for control Africa, so new and more sustainable approaches management are required can help reduce impact this exotic pest. Pesticidal plants provide an effective approach African farming research shown their cost-beneficial sustainable. In order optimize botanical extracts control, we initially screened ten commonly used plant species. laboratory trials, contact toxicity feeding bioassays showed differential effects. Some had little no effect when compared untreated controls; thus, only five most promising were selected detailed study. tests, highest larval mortality was obtained from Nicotiana tabacum (66%) Lippia javanica (66%). Similarly, bioassay L. (62%) N. (60%) exhibited high at concentration evaluated (10% w/v). Feeding deterrence using glass-fibre discs treated with extracts, which Cymbopogon citratus (36%) Azadirachta indica (20%) potent deterrents among pesticidal evaluated. screenhouse experiment living maize infested larvae reducing foliar damage whilst synthetic pesticide chlorpyrifos damage. Further field trial evaluation recommended, involving fields assess effectiveness contexts.

The Efficacy of Alternative, Environmentally Friendly Plant Protection Measures for Control of Fall Armyworm, Spodoptera Frugiperda, in Maize

Insects, Journal Year: 2020, Volume and Issue: 11(4), P. 240 - 240

Published: April 10, 2020

The invasive fall armyworm (FAW) is threatening maize production and the livelihoods of millions smallholder farmers in newly invaded areas Africa Asia. To control this new key pest to overcome health, environmental, resistance problems related indiscriminate use insecticides, effective sustainable alternative approaches are needed. Here, we report on field trials that tested maltodextrin, neem-based products, ash, soil, as well locally produced alata samina soap, Upper West Greater Accra regions, Ghana. Significant reductions larval numbers crop damage, together with increased yields, were mostly achieved by applying insecticide emamectin benzoate, which was considered positive set trials. However, high efficiency cost–benefit ratios also two products. Maltodextrin only efficient at one sites, a clear dose-dependent effect, while higher dosage nearly benzoate. Due its relatively product cost, maltodextrin generally less cost-efficient. Ash soap treatments, did not efficiently reduce FAW or damage dosages tested; thus, they significantly increase yields.

Profiling of rhizosphere-associated microbial communities in North Alabama soils infested with varied levels of reniform nematodes

Frontiers in Plant Science, Journal Year: 2025, Volume and Issue: 16

Published: March 7, 2025

Introduction Plant roots, nematodes, and soil microorganisms have a complex interaction in the rhizosphere by exchanging or communicating through biomolecules chemicals signals. Some rhizospheric (including endophytic) microbes process such compounds via biogeochemical cycles to improve fertility, promote plant growth development, impart stress tolerance plants. can affect negatively on parasitic nematodes (PPNs) thus hindering ability of parasitizing roots. Next-generation sequencing is one most widely used cost-effective ways determining composition diversity microbiomes environmental samples. Methods This study employed amplicon (Illumina/NextSeq) 16S ribosomal RNA (16S rRNA) for bacteria Internal Transcribed Spacer (ITS2) region fungi profile microbiome cotton grown North Alabama. We isolated DNA (ZymoBIOMICS) from samples triplicates four representative locations Based level Reniform Nematode (RN) Infestation, these were classified as Group A-RN Not-Detected (ND), B-RN Low Infestation (LI), C-RN Medium (MI), D-RN High (HI) determined using sieving method microscopic examination. Results discussion Our analyses identified 47,893 bacterial 3,409 fungal Amplicon Sequence Variants (ASVs) across all groups. Among ASVs, 12,758, 10,709, 12,153, 11,360 unique ASVs Groups A, B, C, D, respectively. While 663, 887, 480, 326 Also, five abundant genera Gaiella , Conexibacter Bacillus Blastococcus Streptomyces . Moreover, belonging Fusarium, Aspergillus, Gibberella, Cladosporium, Lactera identified. The tight clustering nodes Actinobacteria Acidobacteria Proteobacteria shows they are highly similar often found together. On other hand, close association Ascomycota Basidiomycota suggesting that different ecological roles but occupy niches contribute functions within microbial community. communities this had role nutrient recycling, health, resistance some pests including cycles. findings will aid broadening our understanding how interact with crops rhizosphere, influencing pest management.
