Ana Maria Badea, Ioan Pălăgeşiu
At the birds – foot trefoil crop one of the most important aspects is the production of seed, so for the realisation of an integrated protection of a superior quality seed and in a great quantity, is necessary to know the insects that produce the most important damages to this crop. One of these insects is the birds – foot trefoil thrips (Odontothrips loti Hal.). For realizing the chemical treatments in the years 2004 and 2005, the experimental field was placed at the Production and Investigation Station for the Fields Crop from Timişoara. The experimental field was formed from 3 repetitions, each repetition having 7 variants. The usage of pesticides was the same in the all two years of the experimentation, as follows:; V 1 – treated with Fastac 10 EC; V 2 - treated with Mospilan 20 SP; V 3 - treated with Calypso 480 SC; V 4 - treated with Confidor 70 WG; V 5 - treated with Actellic 50 EC; V 6 - treated with Decis 2,5 EC;  V 7 – untreated testifier. In the year 2004 the most efficient product in controlling the birds – foot trefoil thrips is the Actellic 50 EC product, which had an efficaciousness coefficient of 90% and the lowest results were obtained after the usage of Confidor 70 WG product, with an efficaciousness coefficient, it was of 4%. In the year 2005 the best results were obtained after the usage of same product Actellic 50 EC, which had an efficaciousness coefficient of 69,5%, and the lowest results were obtained after the usage of Mospilan 20 SP product, with an efficaciousness coefficient of 43,3%
