Глифосат - наиболее применяемый в мире гербицид. Уровень его экотоксичности широко обсуждают в научной литературе после отнесения соединения к категории «вероятно канцерогенных» пестицидов. Предполагают, что остаточное количество гербицидов может быть наиболее высоким при десикации посевов перед уборкой. Исследования проведены в 2018 г. (центральная лесостепь Новосибирского Приобья - 54°53'13,5"N, 82°59'36,7"E). В эксперименте десикацию посевов осуществили гербицидом Зеро Супер (содержание изопропиламинной соли глифосата 750 г/кг) в рекомендованной дозе, равной 1,5-2,0 кг/га. Остаточное количество гербицидов в растительной биомассе определяли при помощи тест-системы, основанной на принципе иммуноферментного анализа. Предподготовку растительных проб осуществляли согласно рекомендации фирмы Stylab, проводившей валидацию метода для определения глифосата в зерне. Остаточное количество гербицида обнаружено во всех 37 испытанных образцах. Независимо от срока отбора образцов после десикации показатель в зерне не превышал 4,4 мг/кг. Спустя 14 дней после десикации уровень минимального количества пестицида был ниже (0,5 мг/кг) в сравнении с данными, полученными спустя 7 дней (2,6 мг/ кг). Содержание остаточного количества гербицидов в соломе пшеницы оказалось выше, чем в зерне. Наиболее высокие значения показателя обнаружены в биомассе сорной растительности, высохшей при десикации (до 9 мг/кг). В зерне, хранившемся один год, содержание остаточного количества гербицидов не снизилось. Полученные данные сравнили с уровнями ПДК остаточного количества гебицидов в зерне пшеницы, принятыми в мире.</p></abstract><trans-abstract xml:lang="en"><p>The residual amounts of glyphosate in wheat grain after desiccation of crops were determined. Glyphosate is the most widely used herbicide in the world. The level of its ecotoxicity is widely discussed in the scientific literature after the compound was classified as “a likely carcinogenic” pesticide. It is assumed that glyphosate residues can be highest when the crops are desiccated before harvesting. The studies were carried out in 2018 (central forest-steppe of the Novosibirsk Ob region (54°53'13.5"N, 82°59'36.7"E). In the experiment, desiccation of wheat was carried out with the herbicide Zero Super (the content of isopropylamine salt of glyphosate was 750 g/kg) at the recommended dose of 1.5- 2.0 kg/ha. Glyphosate residues in plant biomass were determined using the test system, based on the principle of enzyme immunoassay. Pre-preparation of the samples for the analysis was carried out according to the recommendation of Stylab laboratory, which validated the method for the determination of glyphosate in grain. Glyphosate residues were found in all of the 37 samples tested. Regardless of the sampling period after desiccation, herbicide residues in the grain did not exceed 4.4 mg/kg. In 14 days after desiccation, the minimum pesticide level was lower (0.5 mg/kg) compared to the data obtained in 7 days (2.6 mg/kg). The content of the herbicide residues in wheat straw was higher than in grain. The highest values of glyphosate residues were found in the dry biomass of weed vegetation (up to 9 mg/kg). In the grain stored for 1 year, the content of GR has not decreased. The data obtained were compared with the MRL for the residual amount of glyphosate in wheat grain accepted in the world.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>глифосат</kwd><kwd>остаточные количества</kwd><kwd>зерно пшеницы</kwd><kwd>Приобье</kwd></kwd-group><kwd-group xml:lang="en"><kwd>glyphosate</kwd><kwd>residual amount</kwd><kwd>wheat grain</kwd><kwd>the Ob region</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа выполнена в рамках выполнения государственной программы ГЗ 0533-2021-0005.</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The work was carried out within the framework of the state program GZ 0533-2021-0005.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Захаренко В.А.
