Nemasys^®L

Nemasys^® L is based on the beneficial nematode Steinernema kraussei and provides a rapid curative control of Black Vine Weevil. Nemasys^® L has the added advantage of being cold temperature tolerant. Nemasys^® L will control Black Vine Weevil larvae in soil temperatures down to 5°C, this means it will infect and kill Black Vine Weevil larvae whenever they are active in the soil.

Nemasys^® L 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.

Nemasys^® L is a very robust nematode and can withstand higher environmental pressures than other nematode species; this makes it the product of choice when controlling Black Vine Weevil in field and testing conditions.

Features

• Effective against larvae at warm and low soil temperatures (5°C to 30°C)
• Wide application window (Early February to late November) whenever the larvae are active
• Very robust, long persistence and survival in testing conditions
• Active for up to 6 weeks after application
• Infected larvae turn dark yellow

Conditions

Nemasys^®L can be used in all crop situations where Black Vine Weevil is a pest problem. It is especially suited to application in variable conditions.

• When soil temperatures fluctuate
• When soil moisture levels are low
• For field, bagged and container application
• In peat free media / coir

Apply anytime when soil temperatures are above 5°C. Late autumn applications are very effective at controlling Black Vine Weevil populations since all the eggs will have hatched and larvae can be controlled before damage to the plant.

Rates

Nemasys^®L can also be applied as a drench and spray application a water volume of 4L / m² is recommended.

Best Application Practice

Use curatively when larvae are present and active

Apply when soil / media is moist

See label and technical notes for specific application advice and for application through injection lines and dilution systems
