How to destroy a star system?

The admiral of a space fleet that belongs to a Type 3 civilization has been given orders to obliterate all planets within the habitable zone of a Sun like star.

Some of the planets have been identified as nests for the larvae stage of swarm of the star eating Space Locus. Death Star type destruction of the planets won't kill the larvae.

The weapon of choice: seed missile

The technology:

• The "seed" of a seed missile is a microscopic black hole.

• The initial size is due to safety reasons. The black hole will evaporate via Hawking Radiation if the containment field is compromised; no secondary explosions possible.

• Because the initial size is useless, the missile has to charge the weapon while in-flight.

• To charge the black hole, the missile taps into Dark Matter and grows the black hole like a crystal.

• The missile can cause the essence of the black hole to precipitate into electrons, protons, neutrons, and elements. example: Uranium or a small Neutron Star. This is done with handwavy physics.

What does the missile need to do to cause the star to obliterate the planets? Would this be a Nova or Super Nova? How far out could the star obliteration stellar objects? asteroid belt? kuiper belt?

Edit

I'm editing this because I feel that I had describe the seed missile poorly. Instead of setting the describing of how it works at the beginning, let me first describe its effect.

The missile is a white hole weapon that can generate a maximum amount of mass - say 0.01 solar mass. This is a rewording of point 5 of the original description along with a new description of the upper limit of its capabilities.

• This is done by causing a black hole to operate like a white hole.
• The black hole doesn't have all the mass, the Dark Matter does - point 4 of the original description
• The black hole is just there as an intermediate step for the Dark Matter -> Normal Matter conversion - clarification of points 2,3, and 4 of the original description
• The size of the black hole determines the rate of the conversion. - new information
• At launch, the size of the black hole is microscopic - ~27 micrograms. - point 1 of the original description
• This allows the missile to maneuver normally at first and become a door stop if compromised. - point 2 of the original description

If this was a chemical reaction, it would be written similar to this:

dark matter -> black hole -> white hole -> normal matter

example usage place a stealth variant of the seed missile in an orbit almost parallel to a dyson-ring star defense system and crank it up to 0.011 solar mass.

other usage throw the seed missile into a star, have it create ?????? type normal matter, and watch the star "go BOOM". This question is about filling in that unknown.

Additional information on the situation

It is estimated that 0.000001% of the star systems in the one galaxy are infected. Each of those star systems need to be 99.44% cleansed within a 1 year time frame. That's 2500 star systems in 365 days. No, you can't split the fleet.
