Late Blight (Phytophthora infestans) in potato — critical
Potato Phytophthora infestans (Late Blight) Uttar Pradesh · Agra, Firozabad, Farrukhabad 02 Jul 2026
critical
Cold humid nights + morning dew ideal for late blight. Early symptoms on lower leaves; can wipe out a crop in 7 days.
Full IPM management advisory (click to expand)
1. Scout DAILY at 45-60 DAP.
2. Prophylactic: Mancozeb 75% WP @ 2g/L before symptoms.
3. On symptom appearance: Cymoxanil 8% + Mancozeb 64% WP @ 3g/L OR Metalaxyl 8% + Mancozeb 64% WP @ 2.5g/L.
4. Third spray if wet weather persists: Dimethomorph 50% WP @ 1g/L OR Fluopicolide 4.44% + Fosetyl-Al 66.7% WG @ 3g/L.
5. Do NOT harvest wet — let the crop dry 2-3 days before digging.
6. Store only sound tubers. One infected tuber ruins a whole store.
Pink Bollworm — critical action window in Bt cotton
Cotton Pectinophora gossypiella (Pink Bollworm) Maharashtra · Vidarbha & Marathwada 29 Jun 2026
critical
PBW breaking Bt cotton resistance — infestation crossed ETL in Amravati, Yavatmal, Buldhana, Wardha. Green boll damage 8-15%. Terminate crop before Dec-end to avoid carry-over.
Full IPM management advisory (click to expand)
1. Install pheromone traps at 8/acre — monitor moth catch weekly.
2. If catch >8 moths/trap/week OR green-boll damage >5%, spray.
3. First spray: Quinalphos 25% EC @ 2ml/L OR Profenophos 50% EC @ 2ml/L.
4. Second spray (7-10 days later): rotate to Emamectin Benzoate 5% SG @ 4g/10L OR Chlorantraniliprole 18.5% SC @ 3ml/10L.
5. Do NOT extend crop past Dec 31 — this is the single biggest carry-over source.
6. Post-harvest: shred stalks + deep plough. Do not stack unharvested cotton in the open.

Brown Planthopper (BPH) hotspots in kharif paddy
Paddy Nilaparvata lugens (Brown Planthopper) Andhra Pradesh · Godavari & Krishna districts 02 Jul 2026
high
Hopper burn spots reported in transplanted rice at 50-70 DAT. Dense canopies + urea over-application worsening.
Full IPM management advisory (click to expand)
1. Drain the field for 3-4 days if BPH count >10/hill — kills eggs.
2. Alternate wetting-and-drying is the single biggest agronomic control.
3. Reduce N-urea top-dressing — over-fed rice attracts BPH.
4. If ETL crossed (10-15 hoppers/hill at active tillering, 25-30 at panicle initiation): Pymetrozine 50% WG @ 300g/ha OR Buprofezin 25% SC @ 800ml/ha directed at the base.
5. Conserve mirid bugs + spiders — natural enemies do half the work.
6. Do NOT use synthetic pyrethroids — they cause BPH resurgence.
Fall Armyworm (Spodoptera frugiperda) — high risk on maize
Maize Spodoptera frugiperda (Fall Armyworm) Karnataka · Northern & Central districts 01 Jul 2026
high
FAW infestation reported at 10-25% damage in maize sown in the last 3 weeks. Whorl-stage damage is worst; act within 5 days.
Full IPM management advisory (click to expand)
IPM steps for Fall Armyworm:
1. Scout early. Look for windowpane feeding on young leaves + fresh sawdust-like frass in the whorl.
2. Hand-pick and destroy egg masses (they're on lower leaf surfaces).
3. Place pheromone traps at 5/acre for monitoring.
4. Spray Emamectin Benzoate 5% SG @ 4g/10L OR Spinetoram 11.7% SC @ 2ml/10L into the whorl at dusk. One application usually enough for whorl stage.
5. Rotate chemistry — do NOT spray the same molecule twice in a row.
6. Avoid broad-spectrum pyrethroids (kill natural enemies).

Anthracnose in chilli — spray window closing
Chilli Colletotrichum capsici (Anthracnose / Fruit Rot) Andhra Pradesh · Guntur & Prakasam 30 Jun 2026
high
Overcast + humid weather driving anthracnose in ripening chilli. Fruit ripe rot 15-25% in unsprayed fields.
Full IPM management advisory (click to expand)
1. Prophylactic spray at flowering: Mancozeb 75% WP @ 2g/L OR Chlorothalonil 75% WP @ 2g/L.
2. Once symptoms visible: Azoxystrobin 23% SC @ 1ml/L OR Difenoconazole 25% EC @ 0.5ml/L — rotate.
3. Pick and destroy infected fruit — do NOT drop in the field.
4. Wider spacing + drip (not flood) — reduce leaf wetness.
5. Post-harvest: shade-dry properly. Wet-drying = anthracnose in storage.
6. Avoid Carbendazim — resistance is widespread.
Yellow Rust (Puccinia striiformis) in wheat — early season alert
Wheat Puccinia striiformis (Yellow / Stripe Rust) Punjab · Sub-mountain & central Punjab 03 Jul 2026
watch
Sub-mountain hotspots in Pathankot, Gurdaspur, Hoshiarpur showing early yellow rust pustules on lower leaves in HD3086, PBW343.
Full IPM management advisory (click to expand)
1. Scout weekly. Yellow rust starts as bright yellow pustules in stripes on the leaf.
2. If detected: spray Propiconazole 25% EC @ 1ml/L OR Tebuconazole 25% EC @ 1ml/L. Two sprays at 15 days apart.
3. Do NOT wait for symptoms on the flag leaf — the yield damage is already done.
4. Prefer resistant varieties for next year: HD3226, DBW187, HD2967. Avoid highly susceptible varieties.
5. Report clusters via NPSS or your local KVK — helps early warning for the whole belt.
Whitefly outbreak on winter mustard & vegetables
Mustard Bemisia tabaci (Whitefly) Rajasthan · Bharatpur, Alwar, Sri Ganganagar 27 Jun 2026
watch
Dry, warm mornings are favouring whitefly buildup on early-sown mustard + winter tomato/brinjal. Virus transmission risk.
Full IPM management advisory (click to expand)
1. Set up yellow sticky traps at 30/acre — cheap monitoring + partial control.
2. Spray neem oil 1% (soap 1ml/L as spreader) at first sighting.
3. If populations high: Flonicamid 50% WG @ 60g/acre OR Diafenthiuron 50% WP @ 300g/acre.
4. Uproot severely affected virus-diseased plants — reservoir for whole field.
5. Avoid Imidacloprid where you've used it 2+ times in the season (resistance risk).
6. In brinjal/tomato: remove alternate hosts (weeds) around the field.

Coconut Rugose Spiralling Whitefly spreading in South India
Coconut Aleurodicus rugioperculatus (Rugose Spiralling Whitefly) Tamil Nadu · Erode, Coimbatore, Salem, Namakkal 24 Jun 2026
watch
Spiralling whitefly + associated sooty mould reported on ~30% of surveyed coconut plantations. Reduces photosynthesis; yield loss ~15% if unmanaged.
Full IPM management advisory (click to expand)
1. This pest is largely controlled by natural enemies — DO NOT spray broad-spectrum insecticides. They kill Encarsia guadeloupae parasitoid (Nature's control).
2. Wash affected fronds with jet water + soap (1%) to remove sooty mould — restores photosynthesis.
3. Yellow sticky traps at 5-10/acre for monitoring.
4. Release Encarsia parasitoid if available (ICAR-CPCRI/state horticulture).
5. Neem oil 3% for hotspot fronds; don't blanket spray.
6. Do NOT bring infested palm nursery material from other states.
