Pear Spray Schedule 2026
Green Tip
हरी कली
Green tissue emerges. Oil spray now kills overwintering scale and mite eggs.
San Jose Scale
सान जोस शल्क
Overwinters under bark. Oil spray at green tip kills crawlers effectively — best window.
Pear Rust
नाशपाती रतुआ
Orange pustules on leaves and fruit. Alternate host is juniper. Remove junipers near orchard to reduce inoculum.
Dose per 200 litres of water
नीचे दिए में से कोई एक रसायन लगाएं
Captan 50 WP
Ziram 27% SC
कीट दिखने पर कोई एक कीटनाशक लगाएं
Horticultural Mineral Oil (HMO)
- Oil spray at green tip gives best scale insect control.
- Prune dead/diseased wood and burn before bud break.
- Remove junipers near orchard to reduce Rust infection.
- Spray only when temperature is above 4°C.
Pink Bud
गुलाबी कली
Buds show pink. Fire Blight and Scab both threaten — apply protectant before rain.
Fire Blight
अग्नि झुलसा
Most dangerous pear disease. Blossoms wilt and blacken (shepherd's crook). Spreads rapidly in warm wet weather above 18°C.
Pear Scab
नाशपाती पपड़ी
Olive-brown lesions on leaves and fruit. Primary infection starts at bud break. Similar to apple scab but more aggressive.
Powdery Mildew
चूर्णिल आसिता
White powdery patches on young shoots. Warm dry days favour spread. Prune silvery terminals immediately.
Dose per 200 litres of water
नीचे दिए में से कोई एक रसायन लगाएं
Streptomycin Sulphate 90% + Tetracycline 10% WP
Hexaconazole 4% + Zineb 68% WP
कीट दिखने पर कोई एक कीटनाशक लगाएं
Thiacloprid 21.7% EC
- Prune Fire Blight-infected branches 30 cm below visible infection. Sterilise tools with 70% alcohol.
- Apply copper-based dormant spray to reduce Fire Blight bacteria.
- Introduce bee hives (3–4 per hectare) at 5–10% bloom for pollination.
- Apply Boron 1–1.5 g/litre foliar spray for better fruit set.
Full Bloom
पूर्ण खिलावट
Full bloom — avoid insecticides. Fire Blight antibiotic spray at 10–20% and 80% bloom only.
Fire Blight
अग्नि झुलसा
Infection through open flowers. Rain + temp >18°C = danger. Apply spray at 10–20% and 80% bloom.
Pear Scab
नाशपाती पपड़ी
Wet weather during bloom drives primary scab infection into expanding fruitlets.
Dose per 200 litres of water
नीचे दिए में से कोई एक रसायन लगाएं
Streptomycin Sulphate 90% + Tetracycline 10% WP
इस अवस्था में कीटनाशक की जरूरत नहीं
No insecticide recommended at this stage
- CRITICAL: Do NOT spray insecticides during bloom — kills bees and pollinators.
- Monitor temperature: if >18°C and rain forecast, apply Fire Blight spray same morning.
- Thin blossoms at 20–30% for better fruit size in dense clusters.
- Remove mummified fruit and dead wood harbouring bacteria.
Petal Fall
फूल झड़ने पर
Critical scab spray window. Psylla and Codling Moth monitoring begins now.
Pear Scab
नाशपाती पपड़ी
Most critical spray window — wet falling petals transmit scab to fruitlets. One missed spray = severe fruit marking.
Pear Psylla
नाशपाती सिल्ला
Nymphs suck sap from shoots and fruitlets. Honeydew causes sooty mold. Can cause complete crop loss if unchecked.
Codling Moth
कोडलिंग कीट
Larvae bore into developing fruitlets. Use pheromone traps to monitor flight activity from petal fall onwards.
Dose per 200 litres of water
नीचे दिए में से कोई एक रसायन लगाएं
कीट दिखने पर कोई एक कीटनाशक लगाएं
Spiromesifen 22.9% SC
Imidacloprid 17.8% SL
Chlorpyriphos 20% EC
- Hang pheromone traps (1 per acre) for Codling Moth from petal fall onwards.
- Psylla spray most effective in early morning when insects are less active.
- Keep 12–14 day interval between scab sprays in high disease pressure areas.
- Apply fruit-setting spray NAA 4.5 SL (4.5 ml / 200 L) to improve retention.
Fruitlet
फल बनने पर
Young fruitlets forming. Psylla second generation and Codling Moth larvae are key threats.
Pear Psylla
नाशपाती सिल्ला
Second generation peak. Heavy infestation causes premature fruit drop and sooty mold coating on fruit surface.
Codling Moth
कोडलिंग कीट
First generation larvae enter fruitlets at calyx. Check pheromone trap counts — spray if >5 moths/trap/week.
Pear Scab
नाशपाती पपड़ी
Secondary infections still possible during wet spells. Continue protective fungicide program until dry weather.
Dose per 200 litres of water
नीचे दिए में से कोई एक रसायन लगाएं
कीट दिखने पर कोई एक कीटनाशक लगाएं
Imidacloprid 17.8% SL
Chlorpyriphos 20% EC
Lambda-cyhalothrin 5% EC
- Fruit thinning: keep 1 fruit per spur / 15–20 cm spacing for good fruit size.
- Check pheromone traps weekly — spray if >5 moths/trap/week.
- Rotate insecticide classes — avoid same mode of action consecutively.
- Apply Calcium foliar spray (CaCl₂ 0.5%) to prevent cork spot and bitter pit.
Pre-Harvest
तुड़ाई से पहले
Last spray before harvest. Strictly follow PHI — market rejection risk is high.
Brown Rot
भूरी सड़न
Monilinia fruit rot — spreads rapidly in warm humid conditions near harvest. One rotting fruit infects all adjacent fruit.
Codling Moth
कोडलिंग कीट
Second generation peak coincides with harvest. Late entry causes harvest losses and storage rejection.
Dose per 200 litres of water
नीचे दिए में से कोई एक रसायन लगाएं
Captan 50 WP
Hexaconazole 5 EC
कीट दिखने पर कोई एक कीटनाशक लगाएं
Chlorpyriphos 20% EC
- STRICTLY follow all PHI labels — market rejections and residue violations are serious.
- Harvest at mature green stage — avoid over-ripening on tree.
- Pick in cool morning hours. Handle gently to prevent bruising.
- Grade and pack immediately — pre-cooling extends shelf life significantly.
- तुरंत: Carbendazim 100 gm या Mancozeb 600 gm / 200 L छिड़कें।
- 3–4 दिन बाद: Boric acid 200 gm + Zinc Sulphate 500 gm + Quick lime 250 gm / 200 L।
- 10–12 दिन बाद: Agromin/Microvit 400–600 gm + Urea 1 Kg / 200 L।
