biosept active

Biosept Active is manufactured on the basis of grapefruit extract, the content of which is 33%. It is a plant cultivation supporter and growth promoter for ornamental plants, fruit shrubs and vegetables, in open field conditions and under protective cover. The product can be used during the vegetation period for watering or spraying plants, on all soil types. Biosept Active is used for better rooting of plants, and to improve their growth during the growing season and yield. It also improves the quality of plants and fruit (including their size and sugar content). It can be used prophylactically every growing season.

Pour the measured amount of the agent into the water tank and stir thoroughly. Do not pour in Biosept before pouring in the water, as the product foams strongly. Rinse the empty container and pour the rinse water into the spray liquid tank. Wash the unit thoroughly after use.

Biosept Oil is a product of natural origin, designed for mechanical destruction of harmful insects and mites. The product contains castor oil (94%) obtained from camelina (gold-of-pleasure – Camelia sativa), a plant of the cabbage family Biosept Oil has a mechanical and physical effect, i.e. the liquid applied on plants by spraying covers insects and mites with a thin and sticky film which impedes breathing, movement and feeding. As a consequence, their life processes are stopped and the pests die.

Biosept Oil is effective against aphids, spider mites (mites), whitefly, greenhouse whitefly, thrips, Psylloidea, Coccinea (whitefly, scale insects) and overwintering forms of some pests.

When used systematically, Biosept Oil reduces plant pest populations to levels below the harmful threshold. Due to mechanical and physical action, insects and mites do not become resistant, which allows for repeated use of the product.

Biosept Oil can be used during the entire vegetative period and even just before fruit harvest –there is no withdrawal period as the preparation does not contain any active substances of plant protection products,

Biosept Oil is recommended for use in areas where pests have been found resistant to chemicals used so far. The product contains natural products, therefore it can be used in organic farming; in Poland, it has a certificate issued by IUNG (Institute of Soil Science and Plant Cultivation), which enables its use on organic crops.

Biosept Oil used properly does not pose a threat to bees.

Biosept Oil used in horticulture provides high quality plants with increased resistance to fungal diseases.

The recommended concentration of Biosept Oil
is 0.9-1.2%, i.e. 9-12 ml in 1 l of water.

Scope of application and recommended concentrations:
Before the first application, especially on delicate ornamental plants, it is advisable to carry out a trial treatment to check for symptoms of plant damage within a few days.

Due to the contact effect, apply the spray thoroughly on the pest areas – especially the underside of leaves.

In summer, the treatment should be carried out before evening or early morning when the temperature is not high and the sun’s rays are limited. The product should dry on the plant for about 3 hours after application. Recommended to be applied at temperatures not exceeding 24 oC. Thoroughly cover the entire plant and pests present. Do not apply in direct sunlight.

Field and covered vegetables

Biosept pH Control is used to test soil acidity. The active substance is Hellig’s fluid, a few drops of which are applied on a bit of soil poured into a recess on a special plate attached to the set.

Instructions for use of the Biosept pH Control soil acid meter

Importance of soil acidity:
Plant growth is affected by a number of different factors, including the acidity of the soil in which the plants grow. Determination of soil pH is one of the basic horticultural aids, as it is one of the indicators for determining the agrotechnical culture of the soil. Inappropriate pH can have a very negative effect on plant growth and rooting. It thus causes a reduction in the population of positive microorganisms and other microorganisms that biologically revitalise the soil. Consequently, it leads to a reduction in the availability of micronutrients, nutrients, water, etc. to plants.

Soil types by pH:

  • Very light soil, pH 5.1-5.5 which is the recommended pH value for most heather plants.
  • Light soil, its pH should be 5.6-6.0, which is a value appropriate for sandy and loamy sand soils.
  • Medium soil, its pH should be 6.1-6.5, which is a value typical of sandy loam.
  • Heavy soil, its pH should be 6.6-7.0, and it is not tolerated by acid-loving plants.


A pH below 4 is not tolerated by cultivated plants. In contrast, in soil with pH above 7.5, micronutrients are not available to most plants (although some plants have a high tolerance for soil pH).

Acidification or deacidification of soil:
The most common way to deacidify and regulate soil pH is to use lime in various forms (application details are provided by fertiliser manufacturers on the packaging). To acidify the soil, mix it with acid peat (or spread on the surface, but then acidification process is slower). Instead of peat, also composted coniferous sawdust, bark, conifer needles, acid compost etc. can be used.

Directions for use:

  • Place a teaspoonful of the soil sample into the round recess on the plate and press down.
  • When dispensing Hellig’s fluid with a dropper, pour the soil in the plate recess until the fluid is absorbed and a thin layer of liquid forms on the surface.
  • Wait about 1 minute, then tilt the plate and in this way pour the excess fluid through the channel to the transverse recess.
  • Compare the colour of the liquid with the colour scale on the plate and read off the pH value.
  • After each measurement the plate should be washed with water and wiped dry before the next use.
  • Important: This soil test method gives an overview result and is sufficient for hobby gardening. However, in order to test the pH with strict accuracy, the
    soil must be tested in an accredited laboratory.

Quality control:

Each batch of fluid is checked for quality by the manufacturer before it is placed
on the market. Yet it is also possible to check the quality of Hellig’s fluid at home (without chemical reagents, whether it colours well). To do this, put (or pour) into the plate recess some of the products available at home, using the same method as for the soil test. For example, lemon juice (citric acid) or vinegar will turn a strong red colour (acid reaction). Fresh yoghurt, buttermilk or apple will be slightly less acidic.

Sugar or water, for example, will have a pH 7 – neutral. Strong blue colour (alkaline reaction) will be obtained from baking powder (or soda), egg white, cigarette ash, etc.
