    Nemasys® H – advanced biological control

    Nemasys® H is based on the beneficial nematode Heterohabditis bacteriophora and provides a rapid curative control of Black Vine Weevil.

    The benefits of Nemasys® H for horticulture
    No pest resistance issues
    Compatible as a tank mix partner in integrated pest management programs
    Rapid knockdown
    Active for up to six weeks after application
    Safe for the applicator and field workers

    Nemasys® H can be used to give rapid control when environmental and application conditions are perfect. If there is any concern over these application conditions we recommend the use of Nemasys® L.

    Nemasys® H contains nematodes in their vigorously infective juvenile stage. These aggressive organisms actively seek out Black Vine Weevil 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 insect and release a new generation of infective juveniles which disperse in search of further larvae.

    How to use

    For optimum results:
    Treatment should be applied when Black Vine Weevil larvae are present. Soil or media temperatures should be between 12°C and 30°C for at least two weeks after application. The soil or media should be moist. Routinely treat new material coming onto the nursery that may contain Black Vine Weevil larvae. If product is applied over foliage, irrigate immediately with plain water.

    Drench application: preferred method, especially where crop canopy is dense.
    Strawberry application: drench each plant individually, direct application around the base of each plant avoiding run off.
