Study of the effectiveness of the herbicide Division 25 NEO, CE on rice crops in the Primorsky Territory

The biological and economic effectiveness of the herbicide Division 25 NEO, CE (active florpyrauxifen-benzyl) on rice crops was studied. The herbicide is at the stage of registration for use in the Russian Federation. The studies were conducted on rice irrigation systems of the agricultural agricultural production complex “Lugovoye” of the Khorolsky district – 2018 and LLC “Smena” of the Chemigovsky district – 2019. The soil of the experimental plots is meadow-gley, the mechanical composition is heavy loam. Herbicide Division 25 NEO, CE was used at application rates of 1,0 and 1,2 l/ha in 2 periods: during the period of appearance of 2–3 leaves and tillering of rice. The drug completely destroyed the species of barnacles and saffron, and effectively restrained the development of seaside tuber, peppermint and marsh broadleaf weeds. When introduced into the tillering phase, rice was reliably controlled by irrigated bluegrass. The use of the herbicide Division 25 NEO, CE over 2 years of research contributed to an increase in rice grain yield by 24,0–36,4 c/ha.
