Abstract
The invention relates to synthetic combinations of two or more pure genotypes cloned from the Colombian wild-type Spodoptera frugiperda nucleopolyhedrovirus isolate (NPV003=SfCOL) and to biopesticidal compositions having an active ingredient comprising at least two synthetic combinations and, optionally, a S. frugiperda granulovirus. The compositions of the invention may contain ultraviolet protectants, diluents, coating polymers, surfactants and/or pH regulators and are effective for the biological control of insects in crops, such as corn, rice, cotton, sugarcane and grasses.
Claims9
A biopesticidal composition comprising:
- a) occlusion bodies of the nucleopolyhedrovirus NPV003, isolated from Spodoptera frugiperda further comprising the sequences sf23 and sf24, as set forth in SEQ ID NOs.:
- 1 and 2 respectively;
- b) biological enhancer which is granulovirus VG008, characterized by a PstI restriction pattern and further characterized because its genome comprises a specific sequence SFGV24 as set forth in SEQ ID NO. 5, or proteins derived thereof;
- and
- c) excipients selected from the group consisting of ultraviolet protectant coadjuvants, diluents, coating polymers, surfactants and/or pH regulators or combinations thereof.
