Description
Изобретение относитс к химическим средствам борьбы с нежелательной расти тельностью в посевах возделываемых кул тур. Известен способ борьбы с нежелательной растительностью, включающий до- и послевсходовую обработку посевов произв ными замещенного 1,3,4- тиадиазо ла общ формулы где R - алкил, галоидалкил, галоид,алкоксиалкил , алкил-, алкенилили алкинилмеркаптогруппа, алкил сульфонил; R- - С -С. - алкил, X - карбонил или сера; ОН OR X-:№ II II -X Isr-R Rv3 / где R - водород, алкил, галоидалкил или алкилсульфонил; R и R - НИЗШИ1 алкил. Однако известные гербициды недостаточно активны и избирательны в посевах хлопчатника и злаковых культур. С целью усилени гербицидной активноси и избирательности действи предлагает до- и поспевсходовую обработку посевов роизводить производными замещенного 1, ,4- тиадиазола общей формулы IT в которой Р - апкил, алкенип, галоидалкип , незамещенный или замещенный аралкил или арил, алкип- или аралкилтио-, алкил- или аралкилсульфонил, алкил- или арал килсульфоксигруппа; R -метил или этил; Т1 - 1 или 2, в дозе 0,5-10 кг/га. В табл. 1 перечислены производные замещенного 1,3,4- тиадиазола, испытанные в качестве гербицида. Пример 1, Семена тест-растений высевают в почву, обрабатывают ее испытуемыми соединени ми и через 3 недели провод т учет гербицидной активности и избирательности действи по п тибальной шкале: 0- отсутствие поверждений 1- легкое повреждение или замедление 2- отчетливое повреждение или задержка ростаThe invention relates to chemical means of controlling undesirable plant growing in crops of cultivated crops. There is a known method for combating undesirable vegetation, which includes the pre- and post-harvest treatment of crops with derivatives of substituted 1,3,4-thiadiazole of the general formula where R is alkyl, haloalkyl, halo, alkoxyalkyl, alkyl-, alkenyl or alkynylmercapto, alkyl sulfonyl; R- - C-C. - alkyl, X - carbonyl or sulfur; OH OR X-: No. II II -X Isr-R Rv3 / where R is hydrogen, alkyl, haloalkyl or alkylsulfonyl; R and R are LOWCH1 alkyl. However, known herbicides are not sufficiently active and selective in crops of cotton and cereals. In order to enhance the herbicidal activity and selectivity of action, it is proposed to pre- and post-harvest treatment of crops by derivatives of substituted 1, 4-thiadiazole of the general formula IT in which P is apkil, alkenip, haloalkip, unsubstituted or substituted aralkyl or aryl, alkyp or aralkylthio, alkyl or aralkylsulfonyl, alkyl or aral Kilsulphoxy; R is methyl or ethyl; T1 - 1 or 2, at a dose of 0.5-10 kg / ha. In tab. 1 lists the derivatives of substituted 1,3,4-thiadiazole, tested as a herbicide. Example 1, Seeds of test plants are sown in the soil, treated with test compounds and after 3 weeks, the herbicidal activity and selectivity of action are taken into account on a five-point scale: 0 - no damage 1 - slight damage or slowdown 2 - distinct damage or growth delay
Таблица 1 3- сильное повреждение или недостаточное развитие, или всхожесть 50% 4- взошедшие растени частично погибли , или всхожесть 25% 5- растени полностью погибли, или не взошли. Результаты опытов приведены в табл. 2. Пример 2. Тест-растени высотой 15 см обрабатывают испытуемыми соеени ми , через три недели определ ют бицидную активность по п тибальной шка0- отсутствие повреждений 1отдельные легкие п тна ожогов 2- отчетливое повреждение листьев 3- отдельные листь и части стеблей частично отмерли 4- растени частично отмерли 5- растени полностью отмерли. Полученные результаты приведены в бл. 3.Table 1 3 - severe damage or insufficient development or germination 50% 4 - ascended plants partially died, or 25% germination 5 - plants completely died, or did not ascend. The results of the experiments are given in table. 2. Example 2. Test plants with a height of 15 cm are treated with test soils, after three weeks the bicidal activity is determined by a five-fold scale — no damage 1 separate light spots of burns 2 - distinct damage to leaves 3 - separate leaves and parts of the stems partially dead 4 - the plants are partially dead. 5 - the plants are completely dead. The results are shown in bl. 3
