Abstract

Robotic technologies are affording opportunities to revolutionize the production of specialty crops (fruits, vegetables, tree nuts, and horticulture). They offer the potential to automate tasks and save inputs such as labor, fertilizer, and pesticides. Specialty crops are well known for their high economic value and nutritional benefits, making their production particularly impactful. While previous review papers have discussed the evolution of agricultural robots in a general agricultural context, this review uniquely focuses on their application to specialty crops, a rapidly expanding area. Therefore, we aimed to develop a state-of-the-art review to scientifically contribute to the understanding of the following: (i) the primary areas of robots’ application for specialty crops; (ii) the specific benefits they offer; (iii) their current limitations; and (iv) opportunities for future investigation. We formulated a comprehensive search strategy, leveraging Scopus® and Web of Science™ as databases and selecting “robot” and “specialty crops” as the main keywords. To follow a critical screening process, only peer-reviewed research papers were considered, resulting in the inclusion of 907 papers covering the period from 1988 to 2024. Each paper was thoroughly evaluated based on its title, abstract, keywords, methods, conclusions, and declarations. Our analysis revealed that interest in agricultural robots for specialty crops has significantly increased over the past decade, mainly driven by technological advancements in computer vision and recognition systems. Harvesting robots have arisen as the primary focus. Robots for spraying, pruning, weed control, pollination, transplanting, and fertilizing are emerging subjects to be addressed in further research and development (R&D) strategies. Ultimately, our findings serve to reveal the dynamics of agricultural robots in the world of specialty crops while supporting suitable practices for more sustainable and resilient agriculture, indicating a new era of innovation and efficiency in agriculture.

Abstract

O coentro e uma olericola de grande importância no Brasil, principalmente por suas propriedades medicinais e utilizacao como temperos nas receitas nordestinas e geracao de renda para pequenos produtores. No entanto agentes fitopatogenicos tem causado diminuicao na area plantada dessa olericola, em grandes areas produtivas no estado da Paraiba. Esse trabalho objetivou identificar o agente causal de tombamentos em plantas de coentro no municipio de Lagoa Seca, PB. O experimento foi conduzido no laboratorio de Fitopatologia (LAFIT), da Universidade Federal da Paraiba (UFPB). Foram coletadas plantas de coentro, de uma propriedade rural de Lagoa Seca, PB que apresentavam sintomas de murcha e tombamento. Apos a observacao dos sintomas as plantas foram encaminhadas ao LAFIT, onde foi realizado o isolamento da planta, em meio de cultura Batata Dextrose e Agar. Apos 7 dias do isolamento, as colonias fungicas foram identificadas em microscopio otico. Seguido a obtencao de cultura pura do patogeno deu-se continuacao aos postulados de Koch. Apos a observacao dos sintomas, realizou-se a inoculacao em plantas de coentro com suspensao de 1 x 10 5 esporos/mL, e observou-se a reproducao dos sintomas. Em seguida, realizou-se o re-isolamento das plantas inoculadas anteriormente, a partir das plantas sintomaticas em comparacao com as plantas de coentro coletadas, elas apresentavam os mesmos sintomas, de murcha e tombamento. Dessa forma foram realizadas todas as etapas que compoem os postulados de Koch. Por tanto, atraves dos testes realizados o patogeno identificado foi o fungo Fusarium sp., confirmando ser o agente causal do tombamento de plântulas de coentro no municipio de Lagoa Seca, PB.
