POSSIBILITIES OF COMPLEX CONTROL OF PATHOGENS AND PEST ON TOMATO CROPS UNDER HIGH PLASTIC TUNNELS
Journal Title: Romanian Journal of Horticulture - Year 2020, Vol 1, Issue 1
Abstract
The experiment was carried out in 2020, under high plastic tunnels conditions, using the tomato hybrid Prekos F1 and aimed to evaluate the efficacy of different combinations of fungicides with insecticides for complex control of pathogens Alternaria solani (early blight), Fulvia fulva (leaf mold) and pests Tuta absoluta (tomato leaf miner) and Helicoverpa armigera (cotton bollworm). The experimental variants were: 1. Cabrio Top 0.2% + Coragen 0.0175%; 2. Cabrio Top 0.2% + Voliam Targo 0.08%; 3. Dagonis 0.1% + Coragen 0.0175%; 4. Dagonis 0.1% + Voliam Targo 0.08%; 5. Cidely Top 0.1% + Coragen 0.0175%; 6. Cidely Top 0.1% + Voliam Targo 0.08%; 7. Ortiva Top 0.1% + Coragen 0.0175%; 8. Ortiva Top 0.1% + Voliam Targo 0.08%; 9. Untreated control. Six foliar treatments were applied at 10- days intervals. The efficacy of these combinations of fungicides with insecticides was assessed according to the degree of attack (%) for Alternaria solani, Fulvia fulva and Tuta absoluta or according to the frequency of the attacked fruits (%) for Helicoverpa armigera and was between 85.0% and 90.7%. The highest yields were registered in variants 1 (Cabrio Top 0.2% + Coragen 0.0175% - 5,535 kg/m2), 3 (Dagonis 0.1% + Coragen 0.0175% - 5,440 kg/m2) and 2 (Cabrio Top 0.2% + Voliam Targo 0.08% - 5,362 kg/m2) as compared to 4,490 kg/m2 in the untreated control variant. The differences of yield, obtained in addition to the untreated control variant, were very significant in all cases
