Bacillus thuringiensis var. kurstaki (Btk) for Rose Farms in Kiambu, Kenya | Biological Caterpillar Management | Peak Laboratories India
Share
Caterpillar and other susceptible lepidopteran larvae can damage young rose leaves, shoots, buds and flowers, reducing crop quality and marketability.
Bacillus thuringiensis var. kurstaki (Btk) is a microbial biological insecticide widely used in Integrated Pest Management programs targeting susceptible caterpillar larvae.
For commercial rose farms around Kiambu, Kenya, Btk can be incorporated into suitable biological pest-management programs when susceptible caterpillar pests are identified.
Btk for Rose Farms
Btk is particularly associated with the management of susceptible lepidopteran larvae or caterpillars.
Because Btk generally needs to be ingested by susceptible larvae, application timing and coverage of actively feeding plant surfaces are important.
Early larval stages are generally more suitable targets than large, mature caterpillars.
Peak Laboratories Btk
Peak Laboratories manufactures Bacillus thuringiensis var. kurstaki for professional agricultural and floricultural applications.
Liquid — 2 × 10⁸ CFU/ml
Powder — 2 × 10⁸ cells/gram
Peak Laboratories supplies Btk under its BRUISER range.
Application for Rose Farms
Btk can be incorporated into suitable foliar spray programs targeting susceptible caterpillar larvae.
Applications should provide good coverage of leaves, shoots, buds and other plant surfaces where larvae are actively feeding.
Final dosage, pest claims, spray intervals and permitted uses should follow the applicable registered product label.
Caterpillar Management in Roses
Regular crop scouting is important for identifying eggs, newly hatched larvae and early feeding damage.
Starting a microbial Btk program while larvae are small can improve the opportunity for effective biological management.
Applications may need to be repeated according to pest pressure, crop growth and label recommendations.
Btk for Greenhouse Roses
Protected rose production allows frequent crop monitoring.
Greenhouse managers can use pest scouting to identify caterpillar activity early and incorporate Btk into the pest-management program before significant damage develops.
Attention should be given to fresh plant growth because young tissues can be attractive feeding sites for certain caterpillar pests.
Integrated Pest Management
Btk can form part of an Integrated Pest Management (IPM) program involving crop scouting, sanitation, removal of heavily infested material, trapping where appropriate, biological control organisms and compatible crop-protection products.
Correct pest identification remains important because Btk is not a universal insect-control product.
Microbial Caterpillar Management
Btk provides rose growers with a biological tool specifically relevant to susceptible caterpillar pests.
Its targeted biological mode of action makes it useful for inclusion in professionally designed IPM programs.
Performance should be evaluated according to pest species, larval stage, application timing and environmental conditions.
Btk with Other Microbial Biopesticides
Peak Laboratories manufactures several microbial pest-management products including Bacillus thuringiensis var. kurstaki, Beauveria bassiana, Verticillium lecanii and Metarhizium anisopliae.
Each microorganism should be selected according to the target pest and application environment.
