Bio Catch — Product Description

What it is
Bio Catch is a biological insecticide based on the entomopathogenic fungus Verticillium lecanii (also seen as Lecanicillium lecanii in some sources). It contains spores and mycelial fragments of this fungus.

Active content / Formulations

Powder form: ~ 1.15% WP (wettable powder)
Liquid form: ~ 1.50% LF (liquid formulation)
Spore/mycelial density: about 1×10⁸ CFU/g (powder) or CFU/ml (liquid)

Mode of action

Contact mode: the spores land on the insect surface, attach, germinate, grow through the cuticle (or via spiracles), then proliferate inside the insect. The insect is deprived of nutrients, internal structures are disrupted, and the pest eventually dies (usually in ~2-3 days) after infection.
Works against all life stages: egg, nymph, adult (especially useful for sucking pests).

What pests & crops it is used for

Target pests: Whitefly, Jassids, Aphids, Thrips, Mealybugs, Leaf hoppers, etc.
Crops: Broad range. Cotton, tomato (especially for whitefly), and generally “all crops” for sucking pest control.

Benefits

Eco-friendly / safe: Being biological, it doesn’t leave harmful residues, is safer for beneficial insects and non-target organisms.
Resistance management: Doesn’t encourage pest resistance or resurgence the way repeated chemical use can.
Fits organic agriculture and IPM (Integrated Pest Management) programs.

Usage / Dosage & Application

Formulation	Dosage	Application notes
Powder (1.15% WP)	~ 1.0 kg per acre (≈ 2.5 kg/ha)	Foliar spray. Use at early stages of infestation. Repeat 2-3 applications at ~10-day intervals.
Liquid (1.50% LF)	~ 1.0 L per acre (≈ 2.0 L/ha)	Same as above; spray both upper & under surfaces; better in cooler/humid parts of day.

Other application tips

Apply prophylactically or at early detection of pests for best results.
Avoid mixing with chemical fungicides; compatibility is better with neem or other biopesticides.
Conditions: works best at moderate temperature (~16-26°C) and high relative humidity (70-90%) especially in first 1-2 days after application.
