The objective of the research project was to assess the effectiveness of application of some selected herbicides (Table 1) in seed plantation of Lolium perenne (cv. 'Anna' 2n PL) established in late-summer pure sowing in the first year of utilization. The field experiment was carried out in two series in years 1998-2000 in the experimental Station in Brody. Depending on the specificity of the herbicides, they were applied (using a plot field sprayer) either in the autumn when perennial ryegrass was at the stage of 3-4 leaves or in early spring, when plants of Lolium perenne were at the stage of full tillering and four weeks later. The following parameters were evaluated: weed control efficacy, seed yield, number of generative shoots, number of spikelets per ear, 1000 seed weight, germination and purity of seeds as weil as the profitability index of the applied herbicides. It was found that the highest weed control efficacy reaching the level of 96% was recorded in the case of Lentagran 45 WP. The autumn application of this herbicide was more profitable in comparison with the spring application. The application of Lentagran 45 WP, also in combination with Stomp 330 EC, resulted in 137% increase of seed yield. In the case of the spring herbicide treatment, the highest effectiveness was observed when the mixture of Aminopielik D 450 SL + Chwastox D 179 SL + Starane 250 EC was used. From tested herbicides, the following ones are not suitable for weed control in Lolium perenne seed plantations: Arelon Fox 550 EC, Dicuran 80 WP, Glean 75 WG and Attribut 70 WG. The above mentioned herbicides caused damage to perennial ryegrass and secondary weed infestation leading to lower seed yields. In addition, the application of Attribut 70 WG resulted in reduced seed vitality. The observed enhancement of the seed yield of Lolium perenne was due to higher density of generative shoots, higher number of spikelets per ear and higher 1000 seed weight.
