Cotton is a long-duration (150–180 day) Kharif fibre crop that is highly sensitive to sucking pests and bollworms throughout its life cycle. It progresses through seedling establishment, vegetative/squaring, flowering/boll development and boll maturity, with crop-protection needs changing at every stage.
Cotton
SUCKING PEST COMPLEX (JASSID, APHID, THRIPS, WHITEFLY)
- Symptoms: Leaf curling, yellowing along margins, stippling on young leaves.
- Effect on Crop: Weak, stunted seedlings with poor early canopy.
Solution
- Product: Ditenole (Dinotefuran 20% SG) – MaxxGro Insecticide
- Application: Foliar spray at first appearance, as per label dose.
- Benefit: Fast, systemic knockdown of the entire early sucking-pest complex.
WEED INFESTATION
- Symptoms: Rapid weed growth competing with the slow-establishing cotton seedling.
- Effect on Crop: Reduced seedling vigour and delayed canopy closure.
Solution
- Product: Fyzox (Fluazifop-p-butyl 20% + Fomesafen 20% EC) – MaxxGro Herbicide
- Application: Post-emergence spray once weeds and cotton are actively growing, as per label dose.
- Benefit: Controls both grasses and broadleaf weeds in a single application labelled for cotton.
DAMPING OFF / SEEDLING BLIGHT
- Symptoms: Rotting at collar region, seedlings topple over and die.
- Effect on Crop: Gaps in plant stand and poor final population.
Solution
- Product: Captomaxx (Captan 50% WP) – MaxxGro Fungicide (Seed Treatment)
- Application: Seed treatment before sowing, as per label dose.
- Benefit: Broad-spectrum protective fungicide safeguards seed and seedling from soil fungi.
WHITEFLY & MITE BUILDUP
- Symptoms: Yellow mottling, sticky honeydew and sooty mould on undersides of leaves.
- Effect on Crop: Reduced photosynthesis and vector-borne leaf curl virus spread.
Solution
- Product: Domio (Spiromesifen 22.9% SC) – MaxxGro Insecticide/Acaricide
- Application: Foliar spray at first sign of whitefly/mite build-up, as per label dose.
- Benefit: Highly effective against nymphs and eggs of whitefly and mites.
MEALYBUG
- Symptoms: White, waxy cottony masses on stems, leaf axils and squares.
- Effect on Crop: Sap loss, stunted growth and square/boll shedding.
Solution
- Product: Tolmaxx (Sulfoxaflor 50% WG) – MaxxGro Insecticide
- Application: Foliar spray targeting infested colonies, as per label dose.
- Benefit: Systemic sulfoximine chemistry effective on resistant mealybug populations.
EXCESSIVE VEGETATIVE GROWTH
- Symptoms: Rank, bushy growth with delayed square formation.
- Effect on Crop: Energy diverted from reproductive growth, lower boll set.
Solution
- Product: Prolibb – MaxxGro PGR
- Application: Foliar spray at squaring initiation, as per label dose.
- Benefit: Redirects plant vigour towards fruiting structures and improves crop robustness.
PINK BOLLWORM
- Symptoms: Rosette flowers, small holes in bolls, larvae feeding on lint and seed inside.
- Effect on Crop: Major economic loss in lint quality and yield — the most damaging cotton pest.
Solution
- Product: Shield Pro (Chlorantraniliprole 9.3% + Lambda-cyhalothrin 4.6% ZC) – MaxxGro Insecticide
- Application: Foliar spray from flowering onset at first larval detection, as per label dose.
- Benefit: Advanced broad-spectrum control of bollworms and sucking pests together.
AMERICAN / SPOTTED BOLLWORM (SPODOPTERA)
- Symptoms: Boreholes in green bolls, frass at entry points, larvae inside bolls.
- Effect on Crop: Boll drop and internal boll rot leading to yield and quality loss.
Solution
- Product: Novectin (Emamectin Benzoate 5% + Lufenuron 5% EC) – MaxxGro Insecticide
- Application: Foliar spray at egg-hatch/early larval stage, as per label dose.
- Benefit: Dual-action larvicide effective on all caterpillar instars.
BOLL ROT / ALTERNARIA LEAF SPOT
- Symptoms: Water-soaked lesions on bolls, dark concentric leaf spots.
- Effect on Crop: Reduced fibre quality and premature leaf/boll drop.
Solution
- Product: Maxxvive (Trifloxystrobin 18.3% + Difenoconazole 18.3% SC) – MaxxGro Fungicide
- Application: Foliar spray during humid boll-development weather, as per label dose.
- Benefit: Protective, curative and eradicative control of fungal boll and leaf diseases.
GREY MILDEW / LEAF BLIGHT
- Symptoms: Angular grey-brown lesions on lower leaves progressing upward.
- Effect on Crop: Premature defoliation affecting boll-opening and lint quality.
Solution
- Product: Tavix (Tebuconazole 10% + Sulphur 65% WG) – MaxxGro Fungicide
- Application: Foliar spray at first lesion appearance, as per label dose.
- Benefit: Systemic plus contact fungicide combination checks leaf disease spread.
STINK BUG / BOLL DAMAGE
- Symptoms: Yellow-brown stains on lint, small punctures on boll wall.
- Effect on Crop: Stained, lower-grade lint and reduced market value.
Solution
- Product: Cypermaxx (Cypermethrin 25% EC) – MaxxGro Insecticide
- Application: Foliar spray as bolls approach maturity, as per label dose.
- Benefit: Fast-acting contact and stomach action controls boll-feeding bugs.
UNEVEN BOLL OPENING
- Symptoms: Delayed or uneven splitting of mature bolls at end of season.
- Effect on Crop: Extended, inefficient picking and quality variation across pickings.
Solution
- Product: Minati (Ethephon 39% SL) – MaxxGro PGR
- Application: Foliar spray at 60–70% boll maturity, as per label dose.
- Benefit: Promotes uniform, timely boll opening for efficient harvest.
