Why Nemasys^®G?
_{^{Nemasys® G is a biological control product containing nematodes, which effectively controls young larval stages of the garden chafer beetle (Phyllopertha horticola) in turfgrass. Direct feeding damage to the turf roots is prevented and the associated damage to the turf from birds feeding on the chafers. Nemasys® G is compatible with IPM (Integrated Pest Management) systems. Nemasys® G persists for approximately 4 weeks in moist soils. There is no known resistance of the garden chafer to Nemasys® G.}}

Persists in the soil for approximately 4-6 weeks
Natural product that is safe to users and lawns
Presents no risk of pest resistance
Can be used as part of an Integrated Pest Management (IPM) programme
Available in packs of 50 and 250 million nematodes

How Nemasys^®G works

It contains nematodes which actively seek out the chafer or beetle larvae and enter them through their natural openings.

Once inside the larvae they release symbiotic bacteria, quickly killing the insect pest. The nematodes then reproduce inside the cadaver and release a new generation of infective juveniles that disperse in search of further larvae.

Nemasys^® G is a curative control and therefore can be targeted exactly where the larvae are present and where the secondary damage from birds or mammals is to occur.

Application

Should be applied when young chafer grubs are feeding close to the soil surface, usually August/September (during late October/November grubs move deeper in the soil making them more difficult to target)
Consider scarification in lawns with excessive layer of thatch
Cut the grass short before treatment
Soil should be between 12oC and 30oC during application and for at least two weeks after
Avoid application in direct sunlight; make applications in the evenings or in dull conditions
Ensure soil is moist prior to application and for at least two weeks after
Water the treated area thoroughly and immediately after application with no less than 3 litres per m²
The use of a wetting agent helps the penetration of nematodes into the soil
Two applications 2-4 weeks apart, would help achieve higher levels of control
