How does Vidi Parva work?
Vidi Parva stimulates root growth and improves root initiation, therefore providing an ideal basis for a strong and healthy crop. It also promotes the development of disease-suppressing bacteria around the roots. Vidi Parva stimulates the formation of root hairs which release exudates to create and maintain the rhizosphere micro-biology. The product also ensures the development of a compact and resilient plant to support proactive crop balance.
By applying Vidi Parva, the plant is able to produce auxins more effectively. Auxins are plant hormones that promote root formation. Plants produce auxins with the help of amino acids. Tryptophan, an essential amino acid in the triggering of natural auxin production is an important component of Vidi Parva. These auxins stimulate the formation of fine roots and root hairs and promote the absorption of nutrients from the rhizosphere. This leads to an increase in the amount of proteins, sugars, and chlorophyll in the crop, resulting in a compact crop with plenty of vitality and vigour.
In addition to stimulating root initiation, Vidi Parva will proactively assist in the generative steering of the crop. This is a useful tool in maintaining crop balance throughout the season.
How to use Vidi Parva
Application methods
- Shake the jerry can with Vidi Parva thoroughly before use
- The application tank should be filled with half the required water prior to adding the Vidi Parva.
- Add the correct amount of Vidi Parva to the spray solution
- Mix thoroughly
- Fill up the application tank
- Apply
- Optimum response only occurs when the product is taken up by the plant, either through the roots or leaves
- A separate tank/container is recommended for the proper preparation and application of the products
- Always apply Vidi Parva to the irrigation water after the sand filter, ideally directly injected at the irrigation valve (by means of a Dosatron or Venturi)
- Avoid drainage in substrates when applying drench/drip applications to prevent leaching
- Make sure Vidi Parva does not remain in the irrigation system during the night
- Use disinfectants regularly to keep the irrigation system clean, but do not use Vidi Parva at the same time as the disinfectant
- Ensure that the concentration of Vidi Parva is higher than 200ppm at the plant
- Ensure that the drench reaches the root zone. Soil penetrant adjuvants can be applied to assist transport to the root zone
- Always ensure that the spray tank is clean
- Ensure good crop coverage
- Application rates are based on 1000 litres spray volume per ha
- Optimise crop response with addition of a sticker adjuvant
- Low volume, cold mist equipment
- Ensure good crop coverage
