Nemaplus
Biological control of glasshouse sciarids.
Nemaplus contains infective juveniles of the insect pathogenic nematode Steinernema feltia for biological control of glasshouse sciarids. Application conditions nemaplus should be used as soon as possible upon delivery. The package may be stored for several weeks at 4 to 10°C (see expiry date on package). It should never be frozen or exposed to more than 30°C. The nematodes are infective at compost temperatures from 10 to 25°C. At higher and lower temperatures, nematode efficacy decreases.
Compost should be moist but not wet. Nematodes cannot swim and therefore not move in water-saturated compost. Apply 50 million nematodes on a surface of 100 m2 in 20 to 50 litres of water or, for individual treatment, 10,000 nematodes per litre potting compost should be taken. In case of a higher content of composted green waste or perlite into the substrate mixture, the dosage of nematodes should be increased about 50 %.
Normal spraying equipment can be used as well as drip-irrigation or a dosatron. If possible skip irrigation once before the treatment to avoid compost to become too wet. Treat compost as soon as possible after sowing seed or inserting cuttings. A single application of nemaplus protects crops for approximately 6 weeks. If there is a heavy sciarid infestation, repeat treatment after 10-14 days.
