Nemastar contains infective juveniles of the insect pathogenic nematode Steinernema carpocapsae for biological control of leather jackets, mole crickets and black cutworms in turf and vegetables.
Application conditions: nemastar is most infective at soil temperatures from 15 to 30°C. It is very susceptible to UV-light and to desiccation and should therefore be applied in the evening or with cloudy weather. The soil surface should be moist at the time of application.
Mole crickets: Apply nemastar from April to August, as soon as soil temperatures are above 12°C. Nemastar is very efficient against adult mole crickets, but less efficient against young larvae. Therefore, the treatment shall be repeated in the following year.
Cutworms: Apply from June to August as soon as first larvae are detected. The first cutworms die 4 days after application.
Application directions and rates: Nemastar can be easily applied with a watering can or conventional spraying equipment. Apply nematodes with at least 1,200 litre water per ha. 500 million nematodes should be used for 1,000 m². Irrigate with 1-2 litres of water after application to wash the nematodes off the leaves and to move the product below the soil surface. For optimum results, maintain the soil moist for 3-4 weeks after application.
