Bioinsecticide for your Integrated Pest Management (IPM) program

Met52®

granular

Met52 granular is a bioinsecticide containing the fungus Metarhizium anisopliae strain F52 for use against black vine weevil (BVW) larvae (also registered on thrips in Denmark).

Met52 granular has been authorized in Austria, Belgium, Denmark, France, Germany, Greece, Ireland, Italy, Luxembourg, Netherlands, Switzerland, and UK for the following crops, both in regular soils and in containers:• Strawberries, blackcurrants and red, white or blue gooseberries, brambleberries and/or raspberries• Tree nursery crops and perennial plants• Flower crops and potted plants• Grapes

Potential benefits from using Met52 granular:

• No known resistance

• No chemical residue or harvest restrictions

• No toxicological classification

• Compatible with IPM programs as the preventive tool of the program

How does Met52 granular work?

When Met52 granular is applied to the growing media, the Metarhizium anisopliae spores are removed from the rice carrier and mixed with the substrate. As the insect moves in the growing media the spores make contact with the surface of the insect causing them to germinate. Metarhizium spores grow and penetrate the insect, resulting in its infection and mortality. Formation of fungal spores may emerge from the dead insect. In the absence of sensitive stages of the target insects in the soil or media, spores can survive through the season without germinating.

Hemolymph >(Insect Blood)

Infection process

Spore attaches to insect cuticle.Spore germinates and

recognizes it is on insect cuticle.

Spore forms appressonium infection structure.

Spore penetrates cell wall by physical and enzymatic

means.

Protoplasts form in hemolymph (insect blood) to evade the host defense system and circulate to

create infection, killing the insect.

Hyphae grow from within cadaver penetrating out

through cuticle.

Hyphae produce new spores under adequate humidity that

are readily airborne.

The objective of this study was to determine the persistence of Metarhizium anisopliae (F52), measured as infectivity against black vine weevil larvae, in a soilless potting medium at six wholesale nursery locations across the Willamette Valley, Oregon. A granule formulation (0.30 and 0.60 kg/m3) was incorporated into media at planting and fungal persistence determined over two growing seasons.Larval infection rebounded over the fall and winter months of 2004Published by Elsevier Inc.
