Description
Изобретение относитс к новым химическим Средствам борьбы с нежелательной растительностью , в частности, к производным гидантоина .This invention relates to new chemical agents for controlling undesirable vegetation, in particular, to hydantoin derivatives.
Известно применение гндантоинов в качестве гербицида дл борьбы с двудольными сорными растени ми или гербицида сплошного действи , , например 3,5-диалкилгидантоина. Однако такие гербициды фитотоксичны дл культурных растений, характеризуютс низкой избирательностью действи .It is known to use gndantoins as a herbicide to control dicotyledonous weeds or a continuous herbicide, for example 3,5-dialkyl hydantoin. However, such herbicides are phytotoxic for cultivated plants, characterized by low selectivity of action.
Цель изобретени - повышение гербицидной активности, селективности действи , снижение фитотоксичности.The purpose of the invention is to increase the herbicidal activity, selectivity of action, reduction of phytotoxicity.
Дл этого предлагаетс в качестве гербицида примен ть производные гидантонна обш,ей формулыFor this, it is proposed to use hydantonic derivatives, her formulas as a herbicide.

Изучаемые соединени испытывали как гербициды в посевах хлопчатника, сахарной свеклы и других культур.The compounds under study were tested as herbicides in crops of cotton, sugar beet and other crops.
Пример 1. Растени овса, проса, редиса, свеклы и с|)асоли обрабатывали изучаемыми соединени ми в дозе 5 и 10 кг/га как до по влени всходов, так п в период вегетации, когда на растени х по вились 2-3 листочка. Спуст 20-30 дней после по влени всходов и 14 дней после обработки вегетирующпх растений, проводили учет сырого веса зеленой массы растений в сравнении с контролем (без обработки).Example 1. Plants of oats, millet, radish, beetroot and |) asols were treated with the studied compounds at a dose of 5 and 10 kg / ha, both before germination and during the growing season, when 2-3 leaflets appeared on the plants . After 20–30 days after the appearance of seedlings and 14 days after the treatment of vegetative plants, the fresh weight of green mass of the plants was recorded in comparison with the control (without treatment).
Результаты испытаний представлены в табл. 1.The test results are presented in Table. one.
Таблица 1Table 1
Как ВИДНО из табл. 1, вес зеленой массы возделываемых растений резко снижалс при обработке вегетирующих растений.As see from table. 1, the weight of green mass of cultivated plants decreased dramatically when processing vegetative plants.
Растени не подвергались губительному действию гербицида при обработке почвы до по влени всходов, а семена сорных растений полностью погибали, не дава ,всходов.The plants were not subjected to the destructive action of the herbicide during tillage before the appearance of seedlings, and the seeds of weeds completely died without sprouting.
Пример 2. Семена .культурных и сорных растений высевали в почву, которую до по влени всходов обрабатывали соединением формулы I в дозе 1,25 и 2,5 кг/га.Example 2. Cultivated and weed seeds were sown in the soil, which was treated with a compound of formula I at a dose of 1.25 and 2.5 kg / ha before the germination.
Результаты испытаний представлены в табл. 2. Спуст 14 дней, проводили учет веса зеленой массы растений до и после обработки . Как видно из представленных в табл. 2 опытных данных, предлагаемые соединени про вили высокую избирательность действи по отношению к сорным растени м.The test results are presented in Table. 2. After 14 days, we measured the green mass of the plants before and after processing. As can be seen from the table. 2 experimental data, the proposed compounds showed a high selectivity of action in relation to weeds.
