Stem borers are the defining pest of sugarcane. Larvae tunnel into the stalk, producing dead hearts in young shoots and hollowed, wind-broken canes later in the season — and because the damage happens inside the stalk, foliar rescue sprays arrive too late. The practical answer is preventative: insecticidal granules placed in the furrow at planting, where they protect the crop through its most vulnerable establishment phase. Two BNSD granule products serve this role.
Why Granules at Planting
Sugarcane is planted from setts in furrows, which makes it one of the few major crops where a granule application at planting is both practical and highly effective. The granule sits with the sett in the furrow, the insecticide is taken up or encountered as the shoot develops, and the first borer generation meets a protected crop.
A second advantage is agronomic: mediated-fertilizer (药肥) granules carry insecticide and NPK nutrition in the same particle, so the planting pass feeds the crop and protects it in a single operation.
Product Options
0.16% Chlorantraniliprole + Clothianidin GR (NPK 28-8-6, 40 kg bags) — a diamide-plus-neonicotinoid mediated fertilizer with a sugarcane stem borer listed use. The 28-8-6 nitrogen-forward grade suits cane’s early biomass drive. Chlorantraniliprole acts on the ryanodine receptor of chewing larvae; clothianidin adds systemic biting-pest activity through root uptake.
3% Thiamethoxam GR (2.5 kg×6 bags) — a neonicotinoid (IRAC 4A) granule with contact, stomach and systemic action, applied for sugarcane stem borer per the Chinese registration label.
| Product | Actives | Nutrition | Pack | Placement |
|---|---|---|---|---|
| Mediated fertilizer GR | Chlorantraniliprole 0.16% + clothianidin | NPK 28-8-6 | 40 kg bag | In-furrow at planting |
| Thiamethoxam GR | Thiamethoxam 3% | — | 2.5 kg×6 bags | In-furrow / broadcast |
Application Notes
- place granules in the open furrow with or directly over the sett, then cover — root-zone contact is what drives systemic uptake;
- keep granules dry until incorporation; broadcast evenly where in-furrow placement is not practical;
- follow the label of the destination market — the rates shown here follow Chinese registration practice (667 m² = 1 mu ≈ 1/15 ha);
- combine with standard field hygiene: removing old stubble and crop debris reduces the overwintering borer population before the season starts.
FAQ
Can one application last the season?
A planting-time granule protects the establishment phase, which is where borer damage costs the most tillers. Later generations may need monitoring; scout for dead hearts and follow the destination-market label for follow-up options.
Is the mediated fertilizer a fertilizer or a pesticide?
Both — that is the point of the format. Each granule carries NPK nutrition and insecticide actives together, so one application does two jobs and labor drops accordingly.
Are these products available for export?
Yes. Both granules are part of the BNSD export catalog, shipped in 40 kg bags and 2.5 kg packs respectively, with OEM packing options on request.
Do the granules work against other soil pests?
The chlorantraniliprole + clothianidin GR line also carries registered uses for soil pests in maize, peanut and tuber crops — the format is the same, the NPK grade and label differ by crop.
