Fungal biological protection
CQMa421 is a strain-defined fungal technology for crop protection, with research from Chongqing University and distinct crop–pest uses in its Chinese registration record. It extends the portfolio to citrus psyllids and selected vegetable and field-crop pests.

A biological option addressing citrus psyllids.
Tomato whiteflies, cucumber aphids and cowpea beet armyworm have separate label entries.
Chongqing University documents the development of CQMa421-based fungal products.
The fungal species recorded for CQMa421.
Use the full strain identifier in technical documentation.
The original PD20171744 record describes a oil dispersion with a declared biological content of 8 × 10⁹ spores/mL. These figures identify the recorded formulation and are read with its market label.
Public technical records describe the biological identity, target and application context. Each record retains its own strain, formulation and market scope.
DOCUMENTED APPLICATION
The university records CQMa421 research, rice field use and extension into other crops.
TECHNICAL SCOPE
Rice experience is not a quantified efficacy result for citrus or vegetables.
DOCUMENTED APPLICATION
The label specifies distinct crop–pest pairs rather than unrestricted crop coverage.
TECHNICAL SCOPE
This record defines the original strain, formulation and Chinese application scope. Market-specific product documentation governs regional availability and permitted uses.
Psyllid pressure is assessed within orchard pest monitoring. Keep the specific crop and pest paired throughout technical planning. Wheat aphids and maize fall armyworm are additional documented targets.

Select the product and application programme for the crop, growing conditions and applicable market label.
Species, strain and formulation should match the product file.
Batch documentation should cover biological content, viability and quality period.
Maintain separate records for each crop–pest combination.
No. The documented target is the psyllid insect. This is not a claim to cure or directly control the bacterial disease.
No. Each strain and formulation has its own crop and target documentation.
