The said growth regulator, containing organic nitride with nitro-halo band, consists of 0.3115-1.35% of plant growth auxin, 98-99.5% of water, 0.1-0.3% of complexing agent and 0.05-0.5% of the second auxin. The above-said second auxin has molecular formula of C21HnClF6N2O3, and is 1- 4-(2-chloro-2,2,2-trifloro-p-methylbenzyloxy)-2-chlorobenzyl]-3-(2,6-difluorobenzyl formyl) urea. The said growth regulator contains two kinds of effective matter; and the second auxin can promote the plant's absorption of the plant growth auxin. |
