The process of weed development in a sugar beet field was followed under the climatic conditions of mideastern Poland in 1977. The sugar beet was cultivated on loess soil and weeded using two methods: mechanical and chemical (Pyramin 5 kg/ha just after sowing). The results of the study revealed a specific developmental rythm of the particular weed species on each of the weeded objects. The lise of the herbicide delayed the germination of weeds and limited their repeatability, eliminated sonic species from the weed community as well as delaying the start of generative development of some weeds. It also decreased the participation of the fruit and seed shedding phase of the weeds before harvest of the cultivated crop.

Herbicide Activity

In the years 1975-1980, on the Experimental Farm Chylice fields of the Warsaw Agricultural University, herbicide activity was evaluated on commonly appearing weed species in sugar beet cultivation. The most frequent weeds were: <i>Chenopodium album, Echinochloa crus-galli, Polygonum convolvulus</i> and <i>Polygonum lapatifolium</i>. Preemergence use of chloridazon and furthermore postemergence use of phenmedipham were most effective in control. Metolachlor or bentiocarb mixed with metamitron and chloridazon were effective too. It was found that 70% control of <i>Chenopodium album</i> increased crops of sugar beets by about 25% on the basis of two years experiments (1979-1980), differing in quantity and periods of rainfall, a visible dependence of herbicide effectiveness on climatic conditions was demonstrated.

Frequent Species

<p>Field studies were carried out in 1989–1995 and 2006–2012 on plantations of sugar beet (<em>Beta vulgaris</em> L. subsp. <em>vulgaris</em>). During this period, 542 phytosociological relevés were made using the Braun-Blanquet method. In total, 46 weed species were found. In 1989–1995, the occurrence of 36 segetal species was reported. The highest cover indices were determined for <em>Chenopodium album</em> and <em>Amaranthus retroflexus</em>. <em>Galium aparine</em>, <em>Echinochloa crus-galli</em>, and <em>Elymus repens</em> were the dominant species, as well. Analysis of the frequency of occurrence revealed one constant species (<em>Chenopodium album</em>), two frequent species (<em>Amaranthus retroflexus</em> and <em>Galium aparine</em>), and two medium-frequent species (<em>Echinochloa crus-galli</em> and <em>Matricaria maritima</em> ssp. <em>inodora</em>).</p><p>In 2006–2012, the occurrence of 40 weed species on the sugar beet plantations was recorded. The plantations were clearly dominated by <em>Chenopodium album</em>, accompanied by <em>Polygonum persicaria</em> and <em>Polygonum lapathifolium</em> ssp. <em>lapathifolium</em>. Other dominant species comprised <em>Setaria viridis</em>, <em>Galinsoga parviflora</em>, <em>Brassica napus</em> ssp. <em>napus</em>, and <em>Fallopia convolvulus</em>. The <em>Chenopodium album</em> was a constant component of the sugar beet plantations. In turn, no frequent species were observed and six medium-frequent species were found (<em>Setaria viridis</em>, <em>Galinsoga parviflora</em>, <em>Brassica napus</em> ssp. <em>napus</em>, <em>Echinochloa crus-galli</em>, <em>Amaranthus retroflexus</em>, and <em>Capsella bursa-pastoris</em>).</p><p>Noteworthy, the presence of previously unreported species, e.g., <em>Abutilon theophrasti</em>, <em>Hyoscyamus niger</em>, or <em>Artemisia vulgaris</em>, was revealed. These species are rare components in sugar beet crops. A reverse phenomenon, i.e., the disappearance of some species such as <em>Euphorbia helioscopia</em>, <em>Malva neglecta</em>, <em>Rumex acetosella</em>, <em>Sinapis arvensis</em>, or <em>Sisymbrium officinale</em>, was also observed.</p>

Different Soils

The study on weed infestation of root crops in different soils in the protective zone of Roztocze National Park was conducted in the years 1991-1995. As many as 240 phytosociological records, made with the use of Braun-Blanquet method, were taken in potato and sugar beet fields. The number of weed species in sugar beet and potato in the area depended on the soil and type of root crop. In the same environment conditions. the iiuinber of weed species was higher in potato than in sugar beet. The most difficult weed species iii all types of soil were: <i>Chenopodium album, Stellaria media</i> and <i>Convolvulus arvensis</i>. Podsolic soils were highly infested by two acidophylic species: <i>Spergula arvensis</i> and <i>Raphanus raphanistum</i>. Potato in loess soil and brown soil made of loamy sands were highly infested by <i>Echinochloa crus-galli, Equisetum arvense</i> and <i>Galinsoga parviflora</i>. Root crop plantations in brown soils formed from gaizes of granulometric loam texture and limestone soils were infested by: <i>Galium aparine, Sonchus arvensis, Sinapis arvensis</i> and <i>Veronica persica</i>.
