Stage 1: Seed Treatment & Inoculation

Protects from collar rot, rhizoctonia root rot, and establishes nitrogen-fixing root nodules.

Targets:Collar Rot (Sclerotium rolfsii)Root RotSeed Rot
Tank-Mix Recipe & Recommended Inputs:
Input & Technical MoleculePopular ExampleDose per AcrePer 15L KnapsackAgronomic Role
Carboxin 37.5% + Thiram 37.5% DSFungicideVitavax Power2.5g per kg seedN/A (Seed Dressing)Controls internal and contact seed-borne fungi
Bradyrhizobium japonicum LiquidBio-stimulantRhizobium Inoculant10 ml per kg seedN/A (Biological Inoculant)Nodulates roots to fix 30-40 kg atmospheric nitrogen per acre
Mixing Warning: Apply chemical fungicide first, dry in shade for 1 hour, then treat with Rhizobium culture just before sowing.
Expert Tip: Never sow soybean seed deeper than 3-4 cm. Seed coat is delicate and deep sowing reduces emergence by 40%.

Stage 2: Vegetative & Girdle Beetle / Semilooper Defense

150L Water (10 Tanks/Acre)

Girdle beetle females make two parallel ring cuts on petiole/stem and lay eggs; upper plant dries up.

Targets:Girdle Beetle (Obereopsis brevis)Green SemilooperTobacco Caterpillar

Mixing Warning: Coragen and 19:19:19 are 100% compatible.
Expert Tip: Spray immediately upon spotting the first wilted stem with two cut rings. Delay allows larvae to bore into root pith.

Stage 3: Flowering to Pod Setting & Rust Shield

150L Water (10 Tanks/Acre)

Peak flowering and early flat pod formation. Spodoptera litura defoliates foliage and bores into pods; rust causes premature leaf drop.
