The smaller three-litre packs are aimed at the protected crops sector, allowing 0.25-0.5ha to be treated per pack dependent on the use rate, while the 10-litre pack is designed for use on outdoor broad acre crops.
Certis marketing manager Robert Lidstone said: "Following the approval of Spruzit for use through tractor-mounted hydraulic sprayers, broad acre outdoor applications are now a practical option for growers of fruit and vegetable crops. Having looked at the needs of both the protected and outdoor sectors, we concluded that each required a different pack size."
Spruzit contains naturally derived pyrethrins and oils in a formulation that targets the insects' nervous system.
It targets a range of pests including caterpillars, aphids, spider mites, mealy bugs and whitefly at the egg, larval and adult stages.
