nema-green contains entomopathogenic nematodes of the species Heterorhabditis bacteriophora for the biological control of larvae of several chafer grubs (e. g. Billbugs, Japanese beetle, Northern and Southern mask chafer, Oriental beetle, Asiatic garden beetle).
Applicaton conditions: nema-green may be used from end of July to the end of September. The nematodes are most infective at soil temperatures from 12 to 30°. They are very susceptible to UV-light and to desiccation and should therefore be applied in the evening or in dull weather.
Application directions and rates: nema-green can be easily applied with typical spray equipment like a conventional boomsprayer at a dosage of 0.5 million nematodes / m 2 . Use nozzles with at least 0.8 mm diameter. Pressure should not exceed 5 bar. Nematodes should be applied with at least 1,200 l water per ha. Addition of wetting agent will be favourable on thatch.
- >> Thoroughly clean sprayer esp. after insecticide use
- >> Remove all sieves and filters inside the tank and before the nozzles
- >> Add ¾ of the required amount of water to the tank
- >> Dilute packs in a bucket with 5 litres of water
- >> With the agitator running add content of bucket to the tank
- >> Add a wetting agent
- >> Add the remainder of water and begin application
Take care, that the solution will be agitated during filling process and spraying until the tank is empty. Irrigate with 1-2 litres of water/m2 after application to wash the nematodes off the leaves and into the soil.
