Brasil的研究显示，若不防控病虫害和杂草，巴西大豆产量损失可达55%，并推高价格与通胀。","body":"巴西维索萨联邦大学（UFV）与Croplife Brasil合作的研究显示，若不对病虫害和杂草进行防护，巴西大豆作物产量损失可达55%。研究模拟了无控制、部分控制和最优控制三种情景：最优控制下每公顷产量可达72袋，部分控制为52袋，无控制仅32袋。\n\n研究涉及四种病害（包括亚洲锈病和靶斑病）、五种害虫（如烟粉虱）和九种杂草。据研究，为弥补无植保控制的损失，需额外种植3350万公顷，几乎相当于戈亚斯州面积；无管理情景下平均损失达1.213亿吨，价值约2235亿雷亚尔。最优控制下巴西大豆出口收入模拟为442亿美元，无控制则降至266亿美元，每季潜在差额176亿美元。供应减少可能使大豆价格上涨最高49%，并推高官方IPCA通胀率约0.26个百分点。\n\nUFV研究员Ana Carolyne Carvalho表示，大豆生产率下降会显著影响大豆价格及豆油、豆粕等终端产品供应，并传导至猪肉、鸡肉价格。\n\n研究列出四种植保手段：生物技术（如转基因生物）、遗传改良、生物投入品和化学农药，以及混合使用两种以上方法的综合管理。\n\n应用经济研究所（Ipea）的研究显示，2003年至2023年巴西化学农药使用量增长4.4倍，从每年18万吨增至80万吨，成为每公顷农药用量最高的国家（10.9公斤/公顷），为美国的四倍、中国的五倍。大豆、玉米和甘蔗合计占巴西农药消费量的76%。\n\n巴西农业研究公司（Embrapa）研究员Robson Barizon警告，化学农药可能对人体健康产生急性和慢性影响，并污染土壤和水资源、影响授粉昆虫等非目标生物。他还指出，转基因生物既可作为减少农药使用的策略，也可能导致农药用量增加：部分转基因植物抗病虫害，无需农药；但部分转基因植物耐农药，生产者可能加大剂量以除草。对于已获批商业化种植的转基因作物，Barizon称没有确凿科学证据表明其消费对人体健康有额外风险。\n\nCroplife可持续发展协调员Pedro Duarte表示，行业关注农药安全，产品在巴西获批前需经过大量研究。据Ipea研究，2005年至2019年巴西共登记3151种新农药，仅20%被认为低毒。2023年新农药法颁布后，登记速度加快，2024年新批准663种产品，高于2023年的555种。据非政府组织Repórter Brasil引用的卫生部数据，2015年至2025年巴西共登记73391例农药中毒病例，其中去年就有9729例。","why_it_matters":"巴西是中国大豆进口的主要来源国，大豆减产及价格上涨可能影响中国相关进口成本与供应链安排。","cbi_observation":null,"direction_tag":"巴西","primary_category":"宏观市场","secondary_topics":["行业趋势","市场"],"content_level":"编辑整理","event_type":"行业趋势","audience_tags":["大豆进口企业","农产品贸易商"],"event_location":null,"verification_status":"unverified","published_at":"2026-10-31T23:01:20.898Z","display_date":"2026-10-31","source_published_at":null,"source_url":"https://agenciabrasil.ebc.com.br/economia/noticia/2026-10/estudo-mostra-necessidade-de-proteger-soja-para-evitar-perdas","source_name":"Agência
