ACTIVE INGREDIENTS COMBINATIONS FOR PATHOGENS AND PESTS CONTROL ON EGGPLANT CROPS IN THE FIELD

Abstract

The present study aims to identify combinations of active substances for the complex control of pathogens and pests on eggplant crops in the field. The experiments were conducted between 2016 - 2017, in field conditions, using the variety of eggplant Luiza and the following experimental variants: V 1 - Acrobat MZ 69 WG 0.2% + Mospilan 20 SG 0.04%; V 2 - Acrobat MZ 69 WG 0.2% + Vertimec 1.8 EC 0.1%; V 3 - Acrobat MZ 69 WG 0.2% + Laser 240 SC 0.05%; V 4 - Melody Compact 49 WG 0.2% + Mospilan 20 SG 0.04%; V 5 - Melody Compact 49 WG 0.2% + Vertimec 1.8 EC 0.1%; V 6 - Melody Compact 49 WG 0.2% + Laser 240 SC 0.05%; V 7 - Ortiva Top 0.1% + Mospilan 20 SG 0.04%; V 8 - Ortiva Top 0.1% + Vertimec 1.8 EC 0.1%; V 9 - Ortiva Top 0.1% + Laser 240 SC 0.05%; V 10 - untreated control. The average efficacy of the treatment variants experienced in 2016 and 2017 varied between 83.2% (V4) and 85.0% (V8) depending on the combinations of products pathogens and pests control. Analyzing the yields obtained (34.6 -44.0 t / ha in 2016 and 33.5 - 43.1 t / ha in 2017), compared to the untreated control variant (30.4 t / ha in 2016 and 31.1 t / ha in 2017), it is found that the yield differences obtained in addition to the untreated control variants were in all cases, very significant.
