Stage 1: Seed Treatment & Drilling

Protection against loose smut (Kangaroo ear), flag smut, and termite attack in light soils.

Targets:Loose Smut (Ustilago tritici)Flag SmutTermites
Tank-Mix Recipe & Recommended Inputs:
Input & Technical MoleculePopular ExampleDose per AcrePer 15L KnapsackAgronomic Role
Tebuconazole 2% DSFungicideRaxil1g per kg seedN/A (Dry Seed Dressing)100% elimination of internal embryo-borne loose smut
Chlorpyriphos 20% ECInsecticideDursban4 ml per kg seedN/A (Seed Coating)Repels termites and cutworms in sandy loam soils
Mixing Warning: Treat with fungicide first, followed by insecticide. Dry in shade before drilling.
Expert Tip: Drill seed at 4-5 cm depth. Sowing deeper than 6 cm severely delays Crown Root Initiation.

30-35 DAS (After 1st Irrigation)Target Date: 13 Dec 2026

Stage 2: Crown Root Initiation (CRI) & Weed Eradication

150L Water (10 Tanks/Acre)

Post 1st irrigation stage. Phalaris minor (Gullidanda) and broadleaf weeds compete aggressively for nitrogen and moisture.

Targets:Phalaris minor (Gullidanda)Chenopodium (Bathua)Melilotus
Tank-Mix Recipe & Recommended Inputs:
Input & Technical MoleculePopular ExampleDose per AcrePer 15L KnapsackAgronomic Role
Clodinafop-propargyl 15% + Metsulfuron-methyl 1% WPWeedicideVesta / Total160g in 150L water16gDual action: Clodinafop kills grassy weeds; Metsulfuron eliminates broadleaf weeds
Mixing Warning: DO NOT mix weedicide with any insecticide or fertilizer. Spray with Flat-fan nozzle only on moist soil 3-5 days after 1st irrigation.
Expert Tip: Always use a Flat Fan / Floodjet nozzle for weedicide sprays. Hollow cone nozzles cause uneven drift and poor weed kill.

Stage 3: Jointing to Booting & Yellow Rust Shield

200L Water (13 Tanks/Acre)

Rapid stem elongation and ear formation inside flag leaf. Cool humid winter weather triggers devastating Yellow (Stripe) Rust.

Targets:Yellow Rust (Puccinia striiformis)Brown RustPowdery Mildew
Tank-Mix Recipe & Recommended Inputs:

Mixing Warning: Tilt and Boron 20% are 100% compatible. Spray as soon as first yellow powder stripes appear on lower leaves.
Expert Tip: Check field corners and shaded tree edges first. Yellow rust always begins in shaded high-humidity microclimates.

85-90 DASTarget Date: 6 Feb 2027

Stage 4: Milk to Dough & Terminal Heat Stress Defense

200L Water (13 Tanks/Acre)

Grain filling stage. Sudden temperature rise (westerly winds >32°C in March) causes shriveled grains. Late aphids attack earheads.

Targets:Wheat Aphids (Sitobion avenae)Terminal Heat StressPremature Drying
Tank-Mix Recipe & Recommended Inputs:
Input & Technical MoleculePopular ExampleDose per AcrePer 15L KnapsackAgronomic Role
Thiamethoxam 25% WGInsecticideActara50g in 200L water4gCleans aphids sucking sap from tender milky grain heads
NPK 13:0:45 (Potassium Nitrate)Water Soluble NPKMulti-K2 kg in 200L water150gOsmoprotectant; shields grains from desiccating heat waves, boosting test weight by 10%–15%
Mixing Warning: Actara and 13:0:45 are fully compatible. Ensure full earhead coverage.
Expert Tip: Spray Potassium Nitrate (13:0:45) @ 1.5% in early March to counteract heat waves. This single spray increases grain yield by 2–3 quintals/acre.
