Efficiency assessment of herbicides aimed at protecting spring rape against gramineous weeds in the Kaluga oblast

Resumo

This paper provides the efficiency assessment of herbicides based on hizalophone-P-ethyl against gramineous weeds Miura KE and Galera 334 intermixed with spring rape plantings in the Kaluga oblast. However, there was no phytotoxic effect of these weeds on cultivated plants discovered during vegetation. It is shown that the herbicides applied in amounts exceeding 0.8 L/ha produce the most efficient exterminating effect on one-year and perennial gramineous weeds.
