Abstract

The experiments were carried out at the Vegetable Research - Development Station Bacau in open field crops for seeds: bean, parsley, beetroot, celery, lovage, tomato, pepper, eggplant for control of aphids attack. The degree attack (DA%) of black bean aphid was high on the bean – 24.6 %, followed by seed plants of beetroot 11% , parsley - 7%, lovage - 4.2%, celery – 3.5%. Green peach aphid had the biggest attack on the pepper 14.2%, followed at the eggplant – 7.4%, tomato - 5.6% and bean 0.1%. Green potato aphid had a smaller DA% on: tomato – 2.5%, pepper - 1.4%, eggplant – 0.2%. Potato aphid had a smaller DA% in: tomato – 1.8 %, pepper – 0.9%, eggplant – 0.1%. Cabbage aphid attack only cabbage plant of seeds, DA% being 5.9 %. The efficiency of products studied for the control of black bean aphid attack had very good efficiency. So Teppeki - 0.14 kg/ha, had the best efficiency - 99.5%, followed by Mospilan - 0.15 kg/ha - 99.1%, Konflic - 0.3% - 98.4 and Neemes – 025 % - 94.3%. The efficiency of products studied for the control of green peach aphid attack was very good in all variant being over 90%. All products had very good efficiency in control of green potato aphid, over 93%. In condition of low attack of potato aphid which did not exceeded 1.8% DA, all variants had over 93%. The efficiency of products in control of aphids at plant cabbage for seeds was very good: Konflic - 0.3% - 99.0 %, Neemes – 0.25 % - 94.2 %, Teppeki - 0.14 kg/ha - 99.6%, Mospilan - 0.15 kg/ha - 99.4%
