NATURALIS – L From NAD
31 August 2016
Naturalis-L is a bioinsecticide based on the entomopathogenic fungus Beauveria bassiana (strain ATCC 74040). Compared to many other strains of Beauveria, Naturalis-L infects a very wide range of economically damaging pests such as whitefly, mites, thrips and some groups of flies. In addition, the vegetable oil dispersion (OD) formulation means that Naturalis-L has a long shelf-life, is easy to use and gives excellent efficacy in real world conditions.
The mode of action of Naturalis-L makes it a perfect tool for the control of pests and mites on vegetables, fruit crops and ornamentals. Naturalis-L can be successfully used in both organic production and integrated pest management programmes, especially if a reduction in residue levels and number of traditional chemical sprays is desirable.
Naturalis-L does not leave any chemical residues and there is no harvest interval, so it can be applied through the entire life of the crop. As both an insecticide and miticide, Naturalis-L fits perfectly into pest management programmes aimed at minimising the risk of resistance to conventional insecticides. Furthermore, Naturalis-L is compatible with beneficial insects and it is
non-toxic to bees and pollinators.
How does it work?
Naturalis-L contains a naturally occurring soil born fungus. This fungal pathogen of insects begins working once it comes into contact with a target pest. The fungus activates and grows directly through the insect’s cuticle and subsequently multiplies within the body of the insect, which causes death.
Insect activity is disrupted soon after infection although death takes typically 3-5 days. Mobile pests can pick up the infective spores from the leaf surface. Dead insects tend to fall to the floor and thus infections from sporulation tend not to be self-sustaining, although localised infections (epizootics) can occur.
Naturalis-L can infect a wide range of target pests and in many cases all their developmental stages (eggs, immature stages, and adults). In some cases life stages which are protected from coming into contact with Naturalis-L, such as the eggs of thrips which are laid into slits cut into plant leaves, will not be controlled.
Additionally, against certain pests, like some types of flies, Naturalis-L has demonstrated repellent properties when applied in preventive treatments.
