Metavia CQ421™ is a bioinsecticide (oil dispersion) with Metarhizium anisopliae strain CQMa421 as its active ingredient. It is used against citrus psyllids and selected pests of vegetables and field crops, with published research and separate registered uses for each crop and pest.
A biological product for citrus psyllids.
Tomato whiteflies, cucumber aphids and cowpea beet armyworm are separate registered uses.
Published research documents the development of fungal formulations based on CQMa421.
The fungal species recorded for CQMa421.
The full strain identifier is used throughout the technical documentation.
CQMa421 is formulated as an oil dispersion with a declared biological content of 8 × 10⁹ spores/mL.
The following studies and field evaluations concern this strain and its formulations. Each result applies only to the crop, conditions and formulation described.
WHAT THE STUDY FOUND
The university records CQMa421 research, rice field use and extension into other crops.
RESEARCH SCOPE
Rice experience is not a quantified efficacy result for citrus or vegetables.
Psyllid pressure is assessed within orchard pest monitoring, and each use is tied to a specific crop and pest. Wheat aphids and maize fall armyworm are additional documented targets. Approved targets and crops follow the label registered in each market.
