PRESTOP® from Lallemand Plant Care, is a biofungicide that contains the mycelia and spores of a naturally occurring, highly aggressive, soil-borne fungus (Gliocladium catenulatum fungal strain J1446) which survives in the rhizosphere and on the aerial parts of plants for several weeks, affecting a wide range of damaging plant pathogens.

Ornamental plants are particularly susceptible to diseases because of the intensive nature of the cropping cycles. Root diseases are particularly damaging at the early stages of the crop before establishment. Aerial diseases such as Botrytis can be a problem in cool damp conditions and a good protective disease programme is key. PRESTOP® is invaluable in these situations.

ICL recommended plan

Incorporate in to growing media (once per crop) and for continuous protection apply every 4-6 weeks as spray / drench

Young Seedlings and plants

Seedlings and young plants are at risk during establishment and although the growing environment is important, a good, robust preventative fungicide programme is essential. The first 2-3 weeks after germination is when disease is likely to attack. Prestop® is an excellent protectant fungicide which can be applied in a number of ways and will protect against these pathogens.

Drench applications

If unable to apply initially in growing media you are able to apply Prestop® as a drench to plants/crops to protect against:

  • Pythium
  • Phytophthora
  • Rhizoctonia
  • Fusarium
Application rate
  • General drench rate:
    100g Prestop® in 20L water (0.5% solution). This is the same rate for spray, drench and dip applications
  • For drench rates use 10% by volume of the container as drench solution e.g. 1L pot = 1,000ml X 10% = 100ml of solution per pot

Spray applications

When spraying use enough of the solution to make good coverage using a medium quality spray at a maximum 3 Bar pressure. Pressure regulator devices are available which will regulate pressure at the nozzle.

Spray usage protects against: –
  • Botrytis
Dip usage protects against: –
  • Botrytis (only dip stems and foliage)

This guide is to be used in conjunction with the label

Application Rates
  • General dip rate:
    100g Prestop® in 20L water (0.5% solution). This is the same rate for spray, drench and dip applications
  • Use the same 0.5% made up solution for spray and dip applications. Use enough solution to cover foliage and or stems

ICL recommended plan

Apply as high volume spray or drench at above rates. Treat at emergence and for continuous protection repeat every 3-4 weeks

Using a water powered diluter

If you are using a water powered diluter we have put together some example rates of use to make life simpler when setting up to use with PRESTOP®.

Rates of use

  • Example rate of use is 5g/Litre (100g in 20L )

Final concentration

  • For set up example: 2.5kg in 10Litres water and set diluter to 50:1
  • Please note: PRESTOP® needs to be mixed into a cream before adding water and then needs to be constantly agitated whilst applying

Top Tip

It is advisable to remove fine mesh filters from within dosing, irrigation and spraying equipment so as not to filter out any of the beneficial microorganisms when applying Prestop®.
