Fungicides to protect narrow-leafed lupine against anthracnose and other diseases

   The results of laboratory and field studies of fungicide effectiveness of Abacus Ultra, SE (suspension emulsion) and Optimo, EC (emulsion concentrate) against anthracnose pathogen and other lupine diseases are presented. The work was conducted in 2019-2021 in the Bryansk region.

   The object of study were the seedlings and crops of narrow-leafed lupine of the Vityaz variety.

   Under laboratory conditions, the effectiveness of Abacus Ultra (pyraclostrobin 62.5 g/l + epoxiconazole - 62.5 g/l) was studied at the rates of 1.25; 1.5; 2.0 l/ha and Optimo (pyraclostrobin - 200 g/l) - 0.5; 1.0; 1.5 l/ha. Biological effectiveness of the protective and therapeutic properties of fungicides was carried out according to the number of affected seedlings grown in paper-polyethylene rolls compared with the control (no treatment). The highest biological effectiveness of protective and curative properties of Abacus Ultra (98.7 and 97.0 %) and Optimo (97.7 and 93.1 %) against anthracnose showed the norms 2.0 and 1.5 l / ha. Field trials of Abacus Ultra and Optimo at the rates of 2.0 and 1.5 l/ha, respectively, were conducted in the experimental field of the ARLSRI under natural manifestation of anthracnose. The experiment was set in 4-fold repetition, the area of the plot was 34 m². The seeding rate was 1.2 million germinated seeds/ha. The forecrop was presented by spring cereal crops. Crops were treated with a hand sprayer at the rate of 200 l/ha of the working solution. The effectiveness of fungicides was determined in comparison with the control. The biological efficacy of Abacus Ultra and Optimo against anthracnose was 95.3 and 96.3%, respectively. By the shiny bean phase, the number of beans affected by anthracnose in these variants was 1.7 and 1.2 %, compared to 18.7 % in the control. Plant infestation with fusarium blight decreased from 20.2% in the control to 10.9 % and 9.3 %. The spread of blossom blight on beans was reduced by 1.7 times. Fungicides had no inhibitory effect on plant growth. Significant (LSD05 = 0.28) increase in seed yield was 0.82 and 0.98 t/ha, cost recovery was 2.83 and 2.40 rubles.
