A maize season has three pressure points, and each needs a different product form. At planting, the threat lives in the soil — cutworms, wireworms, grubs and other soil pests attacking seed and seedling. Mid-season, the threat moves to the leaf — northern leaf blight, the tasselling-window disease. And through the whorl and reproductive stages, Lepidoptera borers and armyworm chew what the disease did not touch. This guide sets out a program that matches a product to each point, built from the Chinese registrations and program kits of BNSD Agro (Shandong Bainong Sida Biotechnology Co., Ltd.): a mediated fertilizer granule that puts insecticide and NPK into one base-dressing pass, a strobilurin–triazole SC for the leaf disease window, and pre-packed kits for borer and armyworm season. The granule line is in the granules catalogue, the spray products in the insecticides catalogue; label documents and samples run through the contact page.
At Planting: Insecticide and Nutrition in One Granule
The Chinese registration for the 0.16% chlorantraniliprole + clothianidin GR covers soil-pest control in maize, and the product arrives as a mediated fertilizer — a granule that carries the two insecticide actives with an NPK 28-8-6 base in 40 kg bags. This is the Sida Guard mediated-fertilizer line from BNSD Agro, and its logic is agronomic before it is commercial:
- Chlorantraniliprole is a diamide (IRAC group 28), the modern Lepidoptera specialist; clothianidin is a neonicotinoid (IRAC group 4A) with soil-insect reach. Together they cover the two families that matter below ground at establishment.
- NPK 28-8-6 is a maize-grade analysis — the base dressing the crop needed anyway, delivered in the same pass.
- Granule placement puts the active in the root zone without spray water, and without the drift that comes with an early-season foliar pass.
One 40 kg bag line replaces two passes over the field: the fertilizer application and the soil-insecticide application become the same operation.
Vegetative to Tasselling: Northern Leaf Blight
The Chinese label for pyraclostrobin + epoxiconazole 17% SC registers maize northern leaf blight at 40–60 mL/667 m². Northern leaf blight shows as the long, grey-tan lesions that follow the veins and can strip a canopy fast in humid tasselling weather, so the spray is timed against the weather window and the crop stage rather than against full symptom expression.
The formulation is itself the program: pyraclostrobin is the QoI strobilurin (FRAC 11) building the protective deposit, epoxiconazole the triazole (FRAC 3) adding systemic curative reach behind it — two modes of action in one pass, and a rotation built in from the start.
Borer and Armyworm Season: Golden Autumn Kits
Through the whorl and reproductive stages, maize borer and armyworm pressure arrives in bursts that do not wait for procurement cycles. BNSD Agro assembles Sida Golden Autumn kits for this window (company information), in two pack formats:
- The manual pack, sized for one mu (667 m²) — a measured kit for knapsack sprayers, so the grower applies exactly one field-kit per mu without weighing or measuring actives at the field edge.
- The UAV pack, sized for ten mu — the drone-format pack, matching the spray volumes that UAV application actually runs, at a scale operators can plan a day around.
The kit idea is dose discipline: the measuring is done at the factory, not beside the field, and the same pack count becomes the program record. Kit composition follows the seasonal program and the destination label; specifics are confirmed with the company for each market.
The Season Program at a Glance
| Growth stage | Main threat | Program anchor | Chinese label rate |
|---|---|---|---|
| Planting – establishment | Soil pests at seed and seedling | 0.16% chlorantraniliprole + clothianidin GR, NPK 28-8-6 base | 40 kg bags, base dressing |
| Vegetative – tasselling, humid spells | Northern leaf blight | Pyraclostrobin + epoxiconazole 17% SC | 40–60 mL/667 m² |
| Whorl – reproductive stages | Maize borer and armyworm flights | Sida Golden Autumn kits | Manual 1-mu pack / UAV 10-mu pack |
Application and Rotation Notes
- The granule is a base-dressing product: place it with the planting operation per the label method, where moisture will carry the actives into the root zone.
- The 17% SC already carries two FRAC groups; still cap the total single-site passes per season and lean on the multi-site or protectant partners registered locally.
- For the insecticide side, rotate IRAC groups across the borer season and confirm registered targets on the destination label before any off-label tank or sequence.
- All rates above are Chinese registration label rates (667 m² = one mu, ≈ 1/15 ha). Registered uses, rates and intervals in your market are defined by the destination label.
The mediated-fertilizer format and the rest of the granule line sit in the granules catalogue, and the wider spray portfolio in the insecticides catalogue. For kit composition, label documents, samples or OEM packing, contact BNSD Agro.
FAQ
Why choose a granule over a seed treatment or a foliar spray for soil pests?
Placement and timing: a granule goes into the root zone with the base-dressing pass, works from the soil outward through establishment, needs no spray water and adds the NPK the crop needed anyway — one 40 kg bag line replaces a fertilizer pass and an insecticide pass.
What do the two actives in the 17% SC do for northern leaf blight?
Pyraclostrobin (FRAC 11) lays down the protective deposit ahead of new infections; epoxiconazole (FRAC 3) moves systemically and holds back infections already under way — protectant and curative in the same 40–60 mL/667 m² pass.
What exactly is inside a Sida Golden Autumn kit?
The kits are company information: they are pre-packed co-packs for the borer and armyworm season, supplied as a manual pack sized for one mu of knapsack spraying and a UAV pack sized for ten mu of drone spraying. The product line-up follows the seasonal program and the destination label, and is confirmed with BNSD Agro per market.
Do these rates apply outside China?
No. The figures are Chinese registration label rates for positioning. What is legal and correct in your market — registered uses, rates and intervals — is written on the destination label, which should govern every recommendation.
