TurfSolv

A product name for a non-plant protection biostimulant / soil amendment product that consists of a blend of wetting agent and plant extracts, which is said to aid in the reduction and control of chafer grubs and leatherjackets, as well as improve the efficiency of nutrient uptake. When the concentrate is diluted in water: for high stressed areas, which can occur from nematode or disease damage (TS-25) 20-litres diluted in 1,000 litres of water per hectare, whilst for general maintenance (TS-1) 10-litres in 500 litres of water). The substance is said to act as a physical control by blocking respiratory etc. openings in the grubs, effectively smothering them to death (https://www.youtube.com/watch?v=Okof5ZUo_KI, accessed 28th August 2022). The product is suggested to be applied at 3-to-4-week intervals, during the growing season and also whilst grubs are present where these need to be controlled. The product is supplied by Global Bioclean UK, trading as Turfsolv UK).
