The object of the researchBog'liq 7xzfitTga0g1ciDThe object of the research:
The study centers on moderately saline meadow-
alluvial soils in the Republic of Karakalpakstan, employing the winter wheat variety
“Krasnodarskaya-99” and herbicides Dalglifos 500 g/l, Glifor 75,7%, Serto Plus
75%, and Clodimex 8%. These elements form the basis for evaluating the
effectiveness of weed control strategies.
The scientific novelty
of the research is as follows:
in the South, North, and Central regions of the Republic of Karakalpakstan, it
was observed for the first time that 78 types of weeds, spanning 21 families and 65
genera, are prevalent in winter wheat fields;
the distribution of weeds in winter wheat fields showed that families such as
Poaceae (15 types), Chenopodiaceae (14 types), Brassicaceae (9 types), Asteraceae (9
types), and Fabaceae (5 types) are prominent. The damage index indicates that one-
year weeds (61,5%) surpass two-year (5,1%) and perennial (33,3%) weeds;
the study recommends using Glyfor 75,7% herbicide, containing glyphosate,
after the harvest of autumn wheat grain to combat reeds and other dangerous
perennial weeds during the non-growing period, especially in areas with close (1,5-
2,0 m) water bodies;
optimal control measures involve using Serto Plus 75%, dicamba+tritosulfuron-
ethyl, and Clodinafop propargyl+antidote cloquintocet mexil, Clodimex, 8%
herbicides individually or in combination during the wheat flowering period to
combat both annual and perennial monocotyledonous weeds;
application of Glifor, 75,7% herbicide at 1,5 kg/ha during the non-growing
period after harvesting autumn wheat grain, and Serto Plus, 75% at 100 g/ha +
Clodimex, 8% at 0,3 l/ha during the growing season, is found to enhance the growth
and development of winter wheat, leading to higher grain yield and quality;
the economic effectiveness of herbicides applied during the growing period of
wheat against weeds in moderately saline, meadow-alluvial soils has been
demonstrated.
