Assessment of herbicide phytotoxicity

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.
