Complete Kesar Mango Spray Timetable: A Beginner’s Guide for Indian Farmers
Growing Kesar mango is one of the most rewarding ventures for farmers in Maharashtra and Gujarat. However, many new orchardists lose a large part of their harvest to tiny pests like mango hoppers, fungal diseases like powdery mildew, and early fruit drop.
The secret to a healthy, high-yielding mango orchard is spraying the right medicine at the right time. This simple, step-by-step guide explains the exact annual spray schedule based on the age of your mango trees.
Why Tree Age Matters Before You Spray
A young 2-year-old sapling does not need the same spray as a 10-year-old fruit-bearing tree.
- Years 1 to 3 (Growing Stage): Focus on protecting new leaves and building strong branches. Do not allow the tree to bear fruit yet.
- Years 4 to 7 (Early Bearing Stage): The tree starts producing its first mangoes. Focus on protecting flowers and light fruit loads.
- Year 8 Onward (Full Bearing Stage): The tree is at peak production. It needs a complete seasonal schedule for flower induction, pest control, and fruit quality.
Stage 1: Young Mango Trees (1 to 3 Years Old)
During the first three years, your only goal is healthy canopy growth. If flower buds appear, pinch them off by hand so the tree puts all its energy into growing taller and stronger.
| Season | Target Problem | Recommended Spray (Per 1 Liter Water) | Water Needed Per Tree |
|---|---|---|---|
| June – July (Monsoon Start) | Leaf spots, branch rot (Dieback) | Copper Oxychloride (2.5 to 3 grams) | 1 to 2 Liters |
| September – October (Post-Monsoon) | Leaf-eating caterpillars, shoot borer | Lambda-cyhalothrin (Karate) (1 ml) + Mancozeb (2 grams) | 1.5 to 2.5 Liters |
| January – February (Winter Flush) | Thrips, sucking pests, white fungus | Imidacloprid (0.3 ml) + Wettable Sulphur (2 grams) | 2 to 3 Liters |
Stage 2: Young Bearing Trees (4 to 7 Years Old)
From the fourth year, you can start harvesting Kesar mangoes. Use moderate spray volumes to protect the delicate flower panicles.
| Growth Stage & Month | Target Problem | Recommended Spray (Per 1 Liter Water) | Water Needed Per Tree |
|---|---|---|---|
| Post-Harvest (June – July) | Fungal infections after pruning | Carbendazim + Mancozeb (2 grams) | 3 to 4 Liters |
| Before Flowering (October – November) | Early mango hoppers, bud blight | Thiamethoxam (0.3 grams) + Propineb (Antracol) (2 grams) | 4 to 5 Liters |
| Flower Emergence (December – January) | Mango hoppers, powdery mildew | Buprofezin (1.5 ml) + Hexaconazole (1 ml) | 4 to 6 Liters |
| Pea-Sized Fruit (January – February) | Small fruit drop | Planofix (NAA) (0.25 ml) + Potassium Nitrate (13:0:45) (10 grams) | 5 to 6 Liters |
Stage 3: Mature Bearing Trees (8 Years & Older)
Once a Kesar tree crosses 8 years, it carries heavy fruit loads. Follow this 6-step annual calendar for maximum export-quality yield.
1. Post-Harvest Cleanup (June – July)
- What to do: Prune dead and overlapping branches right after harvest so sunlight enters the tree.
- Spray: Copper Oxychloride (3 grams per liter) or 1% Bordeaux Mixture to seal pruning cuts and prevent fungal rot.
2. Flower Induction (August – September)
- What to do: Kesar trees sometimes skip fruiting every alternate year. To ensure regular flowering, apply Paclobutrazol (Cultar) as a soil drench around the root zone (10 to 15 ml per 8-year-old tree).
- Tip: Stop watering the tree from September to November to give it natural stress for flowering.
3. Pre-Flowering Protection (October – November)
- What to do: Once post-monsoon leaves turn dark green and hard, protect the emerging buds from early insects.
- Spray: Propineb (Antracol) (2 grams/liter) + Lambda-cyhalothrin (1 ml/liter).
- Note: If you did not apply Cultar in September, you can add Lihocin (1.5 to 2 ml/liter) in this spray to stop extra leaf growth and encourage flowering.
4. Flower Panicle Emergence (December – January)
- What to do: When flower spikes (mohar) emerge, mango hoppers and white powdery mildew attack rapidly.
- Spray: Imidacloprid (0.3 ml/liter) + Wettable Sulphur (2 grams/liter) or Hexaconazole (1 ml/liter).
- Golden Rule: Never spray insecticides when flowers are fully open. Honeybees visit open flowers for pollination, and spraying will kill them and reduce your fruit set.
5. Mustard to Pea-Sized Fruit Stage (January – February)
- What to do: Tiny mangoes often fall off the tree due to heat or nutrient deficiency.
- Spray: Planofix (NAA) (0.25 ml/liter) + Potassium Nitrate (13:0:45) (10 to 15 grams/liter) + Hexaconazole (1 ml/liter).
6. Egg-Sized Fruit to Pre-Harvest (March – April)
- What to do: Protect growing fruits from fruit flies and sunburn.
- Action: Hang Methyl Eugenol pheromone traps (10 traps per acre) to catch male fruit flies. Spray Borax (3 grams/liter) for better fruit shine and internal quality.
- Safety Rule: Stop all chemical sprays at least 15 to 20 days before harvesting your mangoes.
5 Golden Rules for New Mango Farmers
- Always Follow the Mixing Order: Fill half the spray pump with clean water first. Mix wettable powders (WP) in a small mug before pouring them in. Add liquid solutions (SL) next, and pour oily liquids (EC) last.
- Never Mix Two Similar Insecticides: Do not mix two pyrethroids (like Hamla 550 and Karate) in the same tank. It burns leaves and wastes money.
- Do Not Mix Growth Retardants with Growth Promoters: Never mix Lihocin (which stops shoot growth) with GA3 (which increases shoot growth) in the same spray.
- Spray During Cool Hours: Always spray early in the morning (before 10:00 AM) or late in the afternoon (after 4:00 PM). Afternoon heat can scorch leaves.
- Rotate Your Medicines: Do not use the exact same insecticide twice in a row. Changing chemical groups prevents pests from becoming immune to your spray.
