Abstract

In the Russian Federation, there is a trend towards increased use of pesticides. Irrational and scientifically unjustified use of herbicides aggravates the acute problem of their effects due to the long period of their elimination from ecosystem components. As a consequence, the growth and development of agricultural plants in the subsequent cultivation of chemically treated fields is reduced. The work shows changes in morphometric parameters of test plants (shoot and root length) under the influence of different concentrations of herbicides (“Puma Super 100”, “Secator Turbo”, “Velocity Power”). The test objects were: oats (Avena L.) ‘Sayan, radish (Raphanus sativus) ‘Heat’, rape (Brassica napus) ‘Reliable 92’. Preparations belonging to the chemical class of sulfonylureas showed the highest toxicity. Thus, “Secator Turbo” and “Velocity Power” were found to have a significant effect on the initial stages of seedling development of oat ‘Sayan’, rape ‘Reliable 92.
除草剂植物毒性评估
在俄罗斯联邦,杀虫剂的使用有增加的趋势。除草剂的使用不合理、不科学,加剧了除草剂影响的严重问题,因为除草剂从生态系 统成分中消除的时间较长。因此,在经过化学处理的田地里,农业植物在随后的耕作中的生长和发育会减弱。该研究显示了在不同浓度除草剂("Puma Super 100"、"Secator Turbo"、"Velocity Power")的影响下,试验植物形态参数(芽和根的长度)的变化。试验对象是:燕麦(Avena L.)'Sayan'、萝卜(Raphanus sativus)'Heat'、油菜(Brassica napus)'Reliable 92'。磺酰脲类化学制剂的毒性最高。因此,"Secator Turbo "和 "Velocity Power "对燕麦 "Sayan "和油菜 "Reliable 92 "的幼苗生长初期有显著影响。
