VectoBac WG

In a safe and environmentally friendly way. A water-dispersible granule formulation of Bacillus thuringiensis subsp. israelensis (strain AM65-52)

Works very well for controlling Fungus Gnats which are small black sandfly like insects that , in their larvae stage, eat your fine plant roots leading to a lack of growth and general plant ill-health.

Same active ingredient as Nil Nat.

If you have sandflies hanging around then you more than likely have Fungus Gnats (or Scariad Fly).   This is a very destructive pest and should be treated immediately.  You won’t see any damage on the leaves but your roots will be slowly being eaten away.  Less roots means less water uptake means less growth.

Use   For Hydroponics:   At the rate of 40 gm per 1000 litres added to the nutrient tank.

For soil:   Use as a drench at  2.5 gm per 10 litres for best results as it is a contact

insecticide.

Can be added  to your nutrient mixture for normal watering if drenching is impractical.
