abstract:
The obtained results indicate that under field conditions, the PS1-Meter apparatus can be used when estimating the efficiency of decreasing doses of herbicides CALLISTO 480 SC + ATPLUS 463 (surfactant) and BASAGRAN SUPER on fat hen (Chenopodium album) in stands of grain maize. It can be concluded that, as far as the efficiency of herbicides mentioned above is concerned, their doses can be reduced to 50% of registered ones without any negative effect on the grain yield.
