Paper presents an objective picture of huge development within the second half of 20th century in methods of agrophage control such as destroying and removing their focus, using strongly poisonous inorganic substances as pesticides, biological methods of pests' control as well as weak, toxic chemicals used in low doses. The latest genetic engineering achievements applied to plant protection were also...
The bioindicative research conducted in 1998 concerned the soil polluted by lead in the region of Glass Factory in Krosno. Potato beetle larvae descending to soil for pupation were the soil bioindicator. Samples of soil were collected in the distance of 500 to 1,000 m from the factory emitters, and later the lead content was determined in the Chemical Agricultural Station in Rzeszów. The lead level...
Soil, the main element of natural environment is constantly contaminated and degraded by various man’s activities. Big industrial factories, which emil to the atmosphere excessive quantities of harmful solid, liquid and gaseous substances, arc the main cause of this phenomenon. Improper usage of fertilisers and chemical plant protection agents effects the soil in a lesser degree, but it is still unfavourable...
The research was conducted to evaluate the impact of sulphur compounds on the sex of Colorado potato beetle in the region of sulphur factory in Chmielów near Tarnobrzeg in 1995. The control plantations were situated in the village of Zarębki, about 30km from Chmielów. The object of the study was the average body mass of female and male specimen of the insect after full spring beetle appearance in...
The paper presents some problems that occur in chemical plant protection in the regions polluted by industrial emissions. An example of this problem may be the results of many years' research conducted in this field in the agroecosystem polluted by sulphur compounds in the region of sulphur factory, near Tarnobrzeg. They showed serious disturbances in ecological balance leading to irreversible changes...
The research on the influence of pollution emitted by the WBM-30 bituminous mass factories on the winter wheat-crop was carried out in 1981. The factory was situated in the agricultural area far from the farm buildings in the village of Trzebownisko. The experimental area was divided into four zones (three zones of pollution and one control zone). The wheat ear samples were collected during full grain...
