The article presents the results of vegetation experiment on the influence of different
rates of herbicide Prima Forte 195 – 2-ethylhexyl ether 2.4-D + aminopyralid + florasulam (0.5;
0.6 and 0.7 L ha-1
) under different application methods of plant growth regulator of a natural
origin Wuxal BIO Vita (Ascophyllum nodosum extract + microelements) on the content of
malondialdehyde (MDA) as an important indicator of the intensity of peroxide oxidation of lipids
in plants and on the activity of enzyme glutathione-S-transferase (GST) in the leaves of emmer
wheat.
Experimental scheme included 16 experimental variants: 1 – without application of preparations
and pre-sowing treatment of seeds (control); 2, 3, 4 – Prima Forte 195, applied to vegetative
plants at the rates 0.5, 0.6 and 0.7 L ha-1
; 5 – Wuxal BIO Vita at the rate of 1.0 L ha-1
, applied to
vegetative plants; 6, 7, 8 – Prima Forte 195 at the rates of 0.5, 0.6 and 0.7 L ha-1
in tank mixtures
with Wuxal BIO Vita at the rate of 1.0 L ha-1
, sprayed on vegetative plants; 9 – pre-sowing
treatment of seeds with Wuxal BIO Vita at the rate of 1.0 L t
-1
(background); 10, 11, 12 – Prima
forte 195, applied to vegetative plants at the rates of 0.5, 0.6 and 0.7 L ha-1
at the background of
pre-sowing treatment of seeds with Wuxal BIO Vita at the rate of 1.0 L t
-1
; 13 – Wuxal BIO Vita
at the rate of 1.0 L ha-1
(applied to vegetative plants, treated before sowing with Wuxal BIO Vita
at the rate of 1.0 L t
-1
); 14, 15, 16 – Prima Forte 195 at the rates of 0.5, 0.6 and 0.7 L ha-1
respectively, in tank mixture with Wuxal BІО Vita at the rate of 1.0 L ha -1 –
spraying of plants
and pre-sowing treatment of seeds with Wuxal BІО Vita 1.0 L t
-1
.
It has been found that under the application of Prima Forte 195 the redox state in the leaves of
emmer wheat increased considerably in the direction of increasing the content of MDA. It has
also been proved that herbicide Prima Forte 195 and its mixtures with plant growth regulator
(PGR) Wuxal BIO Vita caused the changes in the activity of enzyme glutathione-S-transferase,
which slightly increased in the initial period in the variants of integrated application of herbicide
and plant growth regulator. However, later the GST activity in the variants of integrated
application of herbicide and PGR decreased, which indicates stabilization and a positive influence
of integrated application of preparations on the detoxification processes in the crops of emmer
wheat.
