The dominant weeds in potato plantings are annuals (chicken millet, bristles, annual bluegrass) and perennial grasses (creeping wheatgrass), annuals (white grass, starweed, odorless three-ribbed, mountaineer species, field violet, small-flowered galinzoa) and perennial yellow, field thistle, field mint). Average infestation of potatoes is 44–85 weeds / m2… Protection of potatoes from weeds is carried out in several stages:
spraying the soil before crop shoots against annual dicotyledonous and cereal weeds (Extrakorn, SE; Camelot, SE; Gezagard, KS; Prometrex Flo, KS; Zenkor Ultra, KS; Stomp, 33% k.e .; Kalif, KE; Tavas, KS ; Screen, KS; Herbitox, VRK; Agritox, V.K .; Agrokson, VR; Dikopur M, V.R .; Khvastoks Extra, VR; Khvastoks 750, VR; Zenkor, VDG; Mistral, VDG; Molbuzin, VDG; Lapis lazuli, SP in water-soluble bags; Magnat, VDG; Soil, VDG), annual dicotyledonous and cereal weeds, incl. tenacious bedstraw (Bandur Forte, KS; Arcade, EC), annual dicotyledonous weeds sensitive to 2,4-D and 2M-4X (Metafen, VRK),
spraying vegetative weeds 2–5 days before the emergence of shoots against annual and perennial dicotyledonous and cereals, incl. creeping wheatgrass (Volnik Super, BP; Volnik, BP; Tornado 540, BP; Glyphos Premium, BP; Clinic, BP; Sprut Extra, BP; Freysorn, BP),
spraying vegetative weeds before crop shoots against annual and perennial dicotyledonous and cereals (Buran Max, BP; Thunderstorm Ultra, BP; Thunderstorm, BP; Tornado 500, BP; Tornado, BP; Glyphos, BP; Dominator, BP; Pylaround, 360 g / l v.r .; Roundup Max plus, BP; Roundup Max, BP; Roundup Extra, BP; Roundup, BP; Hurricane Forte, BP),
spraying on seedlings with a potato height of up to 5 cm against annual dicotyledonous and cereal weeds (Lazurit Super, KNE; Lazurite, SP in water-soluble bags; Zenkor Ultra, KS; Screen, KS; Zontran, KKR; Zenkor, VDG; Magnat, VDG; Mistral , VDG; Molbuzin, VDG), against annual dicotyledonous and cereal weeds, incl. tenacious bedstraw (Arcade, EC),
double spraying: the first – before crop shoots and the second – at a potato height of up to 5 cm against annual dicotyledonous and cereal weeds (Zenkor Ultra, KS; Zontran, KKR; Lazurit Super, KNE; Ekran, KS; Zenkor, VDG; Mistral, VDG; Molbuzin, VDG; Lazurite, SP in water-soluble bags; Soil, VDG),
double spraying: the first – the early phases of growth and development of weeds with a potato height of up to 5 cm and the second – in the early phases of weed growth with a potato height of up to 25 cm against annual dicotyledonous and cereal weeds, incl. tenacious bedstraw (Boxer, EC)
spraying of vegetative weeds with a potato height of 10-15 cm against annual dicotyledonous weeds (Agritox, vk; Agrokson, BP; Dikopur M, v.p.), annual dicotyledonous weeds sensitive to 2,4-D and 2M-4X (Metafen, VRK).
It should be remembered that herbicides based on metribuzin and diflufenican have both a soil effect (penetrating the roots and affecting the seedlings of germinating plants) and leafy (affecting the emerging plants). In addition, when applied to wet soil, they are able to form a protective screen on its surface, thereby preventing the emergence of new shoots of weeds. Metribuzin-containing herbicides such as Zontran, KKR and Lazurit Super, KNE are used only for the growing mass of weed seedlings. The flow rate of the working fluid is 200–250 l / ha.
