Abstract

There was studied impact of Dublon Gold, Titus Plus, MaisTer, Stellar and Adengo herbicides on maize sow productivity and weediness.  The study was carried out on the experimental fields in Primorye in  2008– 2010 and 2014–2017. Soil was brown meadow podzolized  one containing 3.5 percent of humus in the arable horizon.  Agrotechnology was done on the base of soil dumping cultivation.  Soya was the forecrop. In pre-seeding preparation period there was  applied fertilizer of 150 kg/ha. Slavianka and ZPTK 196 maize hybrids under study were seeded of 70 000 seeds/ha. There is shown that application of Doublon Gold (0.07 kg/ha), Titus Plus  (0.38 kg/ha), MaisTer (0.15 kg/ha), Stellar (1.5 l/ha) and Adengo  (0.5 l/ha prior to germination, phases 2–3 and of 5-6 leaves)  herbicides allowed to reduce the number of weeds in maize sowing by 45–82 % and their above-ground mass by 67–88 %. In the control variant (without herbicides) there were registered 244-511  weed plants per square meter average with their total above-ground  mass of 2623–4488 g/m2. The increase in maize yields due to  herbicides application was of 1.33–5.55 t/ha with the control yielding capacity of 0.3–0.86 t/ha. The studied herbicides are arranged in  descending order according to maize tolerance degree as following:  Titus Plus, Adengo, Doublon Gold, Stellar and MaisTer. In case of  overdose or in the places overlapping sprayer passes, Adengo,  MaisTer and Dublon Gold herbicides can have a depressing effect on corn plants and reduce grain yield of the crop by 6–16 %.
