Butterflies Mining Apple-Tree Leaves (Šefrová)

In some years leaves of apple trees can be damaged to a great extent by insect ,particularly butterflies laying eggs. Their larvae feed on internal netting of leaves the skin of which remains undamaged. The result is called a mine. As mines are a kind of a specific damage the causal agent can be often reliably determined.

Assessing Quality of Cereals - Wheat (Faměra)

Cereals comprise a large group of crops that takes up the biggest part of arable soil

i.e. 50%. Their production enables various ways of processing in food industry, fodder industry and for technical purposes. In the majority of cereals utilization of grain for fodder purposes prevails. The ways of assessing the quality of wheat for food industry are included in this article.

Promising and Nontraditional Usage of Preparative Spodnam in Cereals (Kinský)

The active substance in Spodnam - pinolen is a resin. It polymerizes due to presence of air on the surface. of plants thus creating a semi permeable membrane which partly prevents pores in leaves from closing. from closing. This in turn leads to intensification of processes such as transpiration , assimilation and depositing of nutrients.

Brassinosteroides Yield and Quality of Wheat (Hradecká)

The quality of wheat for food industry is primarily determined by genotype, year and agroengineering. Good growing technology rests in, among other things, stimulating vital processes in plants when they are overcoming unfavorable conditions. Also brassinosteroids can be used as stimulators that help to regulate physiological and biochemical

Regulation of Ripening and Harvesting Winter Oil-seed Rape

Promising innovation in regulating ripening of oil-seed rape growths is applying Spodnam DC (1,25 l/ha) + Atonik (0,6 l/ha) together.. Application at the time when the colour of pod turns from green to yellow approximately 22 day before harvest. Yields thus increase by 2 upto 8% and losses during harvest decrease by 3050%. Also the value of HTS increase (by upto 10%) . Oil content also slightly increases.

Chicory Growing (Černý)

Chicory, a crop of pleasantly bitter taste (laktucin, laktukopikrin). Containing dyeing substances and inulin, is traditionally used in coffee industry. Inulin which is a polysaccharide turns into caramel during roasting. The fats, sccharides and oil contained in chicory give rise to substances that provide roasted chicory with the specific taste.

Killing Weeds in Lawns and Danger of Residues

Lontrel 300 is a selective herbicide in a form of soluble (capable of creating mixtures) concentrate to be used for killing dicotyledonous weeds, particularly camomile, wild camomile and teasel in growths of cereals where there was no additional sowing, grasses grown for seeds, corn, oil-seed rape, fodder beet and sugar beet. This herbicide, however, decomposes slowly and hence symptoms of phytotoxicity can occur.

Composting Grasses from Lawns, Subsequent Usage and Problems It Brings About (Cagaš)

Lawns of various types (utility or ornamental lawns, lawns used for sporting activities and lawns as a part of landscape) grown for different purposes (of antierosion, regeneration etc.) produce relatively huge amounts of green grass matter that can be a difficult waste or useful raw material. Amount of this matter obtained in individual fellings differs significantly and depends on many factors.

CLINIC a New Preparative for Prior-Harvest Application in Cereals (Valenta)

CLINIC is a nonselective herbicide with glyphoste as an active substance. Its significant property , particularly for prior harvest application is the speed with which it takes effect..
