Comparison of some adjuvants efficacy with azoprim and buramet using chlorophyll fluorescence.


PMID 17390785

Abstract

This paper presents a quick chlorophyll fluorescence method for the estimation of the influence of some adjuvants applied with Azoprim 50WP (a.s. atrazine) or Buramet 70WG (a.s. metamitron) on oat plants. These herbicides inhibit photosynthetic electron transport in photosystem II, which was measured by means of a pulse PAM-210 chlorophyll fluorometer. Results of the ETR measurements show differences between the efficacies of the studied adjuvants. Olemix 84EC, Atpolan 80EC, Adpros 85 SL and Break-Thru S-240 were the most effective in the mixture with Azoprim, and the last two--also in the mixture with Buramet. Olejan 85 EC did not change the biological action of Azoprim nor Buramet. Moreover, the most effective adjuvants showed relatively good stability.
