Anagallis arvensis L. fruits are globose pyxides. They contain a unique globose columella with 20-30 seeds on its surface. In ripe, open fruits the ball-shaped columella detaches easily and becomes a unique diaspore, which can roll on the ground. This way of dissemination has not been described so far neither in Anagallis nor in other Primulaceae.

Chemical control of weeds in some environments and due to the condition and degree of weed-growth does not bring expected results. For that reason alternative methods have been searched for. Biological control of weeds has been traditionally perceived as reducing the agrophage population to such a level where they do not constitute a threat. In the present research, an attempt has been made to introduce Aglais urticae L. to control the population of Parietaria pensylvanica M. ex. Willd.

The aim of the study was to analyze segetal weeds present in spring barley against the background of changes in pluviothermal conditions observed over the last 20 years (1993–2012) at the Field Experimental Station of the Institute of Plant Protection – National Research Institute in Winna Góra, Poland. Based on the mean value of the Sielianinov hydrothermal coefficient for the three months of spring vegetation, i.e., April, May, and June, three classes of pluvio-thermal conditions (very dry, moderately dry, humid) were distinguished. The phytosociological stability of weed species analyzed during the study period was assessed and the Shannon–Wiener index of species diversity in the communities and the Simpson dominance index were calculated for segetal weeds present in spring barley. In the 20-year period analyzed, Chenopodium album and Viola arvensis exhibited the highest phytosociological stability and the highest abundance in the spring barley crop. Over the years analyzed, the dry spring vegetation periods were characterized by significant precipitation deficiency between late April and mid-June. In the years with favorable meteorological conditions, the weed species diversity measured by the Shannon–Wiener diversity index was higher than in the years with precipitation deficiency. In the very dry years, the species dominance index in the spring vegetation period was higher than in the wet years. The yield loss caused by weed infestation in the very dry years was higher by 6% as compared to moderately dry and wet years.

One of the factors limiting crop growth is weeds. The weeds lead to a reduced performance of the crops. Chemical control methods are considered appropriate for controlling weeds. Therefore, in the fight to control weeds in triticale, the performance of the dual-purpose herbicide sulfosulfuron(Apirus®), mesosulfuron + idosulfuron(Atlantis®), metsulfuron methyl+sulfosulfuron(Total®) with surfactant and isoproton + diflufenican(Panther®) from the sulfonylurea group, and narrow leaf herbicides clodinafobpropargyl( Topik®), pinoxaden(New Axial®), diclofop-methyl(Iloxan®), pinoxaden + clodinafob-propagyl (Traxos ®), fenoxaprop-pethyl + mefen-pyper-d-ethyl(PumaSuper®), tralkoksidim(Grasb®) with 1 liter oil, flam-prop-m-isopropyl(Suffix BW®), and control treatment without herbicides were evaluated. The test was carried out in a randomized complete block design with four replications. Spraying was carried out using a back sprayer. For evaluation of ocular damage, the European Weed Research Council (EWRC) standard method was used. According to the performed studies, the narrow leaves of wild oat and barnyard grass were the dominant weeds. Results showed that all herbicide, except the herbicide tralkoksidim, were effective in weed control. The triticale yield was maintained with the use of these herbicides and none of herbicide had an adverse effect on the crop. In the first weeks of herbicide use, the triticale leaves appeared pale but this problem resolved over time. It seems that the herbicides discussed in this paper can be used on the triticale plant.

A field experiment was conducted in the years 2002- 2004 at the Zawady Agricultural Experimental Station (52o06’ N; 22o06’ E), belonging to the University of Podlasie in Siedlce, Poland. The investigated factors were two soil tillage systems (traditional and reduced) and seven methods of weed control in potato canopies with herbicide application. The aim of the study was to determine the influence of tillage systems and weed control methods on the weed species composition and weed density. Tillage systems, weed control methods and atmospheric conditions prevailing in the study years significantly varied weed infestation of potato canopies at the beginning of vegetation and before tuber harvest. The lowest number of weeds, compared to the control treatment, was recorded in the treatments in which chemical and mechanical weed control had been applied. The treatments with the traditional tillage system also showed lower weed infestation than those in which simplifications had been applied.

There is currently a very favorable climate for biological control of pest weeds. Moreover, biological control plays a significant role in the Integrated Plant Protection Management. Traditional methods of weed control, such as cultivation and the use of herbicides are not practical or desirable for some stands of weeds, and biological control has become an attractive strategy for control of pest weeds. Control of Rumex confertus Willd. by natural enemies that reduce its density is the good example of utilizing biological control on the European and worldwide scale. The aim of the conducted studies was to evaluate the dynamic of population of Pegomya nigritarsis Ztt. (Diptera, Anthomyiidae) on Rumex confertus Willd. and to determine the impact of pest’s injuries on the growth of a plant.
