ARBOK-Repeel-Corn (Four-Layer Selective Pest Control for Corn)

Overview

ARBOK-Repeel-Corn is a four-layer integrated crop-protection system for corn that closes the entire insect-virus-fungal loss segment (approximately 25% of attainable yield), excluding weeds which remain with herbicide-tolerant systems. The four layers are: (a) foliar Arbok-Repeel acid mist against fall armyworm Spodoptera frugiperda, European corn borer Ostrinia nubilalis, and the adult Western corn rootworm Diabrotica virgifera; (b) soil-applied TEG-Repeel combined with the CRONA electrical-pulse module against the Diabrotica root larva — the long-standing weak point of all previous corn defense; (c) a Bacillus-based antifungal protocol against Fusarium and Aspergillus that simultaneously reduces fumonisin and aflatoxin mycotoxin contamination; and (d) a local nutrient supply built on Arbok-URIA (urea), Arbok-Potash (potassium carbonate), Arbok-Phosphate, and CRONA in-field NPK mobilization. The mechanism of Repeel is non-lethal and behavior-driving on the leaf, and lethal on direct contact in the soil; in both cases the action is physico-chemical rather than enzymatic, so no resistance forms. The system delivers approximately 25% recovery of attainable yield at a treatment cost of roughly $30–100 per hectare for the foliar component plus 15–40 kg/ha of TEG-Repeel for the soil layer, together 5–7 times cheaper than conventional chemistry.

Applications

Primary use cases:

• Suppression of fall armyworm (Spodoptera frugiperda), the chief global corn pest, via foliar Repeel reaching the whorl

• Suppression of European corn borer (Ostrinia nubilalis) via foliar Repeel

• Control of Western corn rootworm (Diabrotica virgifera) at both stages: foliar Repeel against the adult beetle (silk, leaves) to break the egg-laying cycle, and TEG-Repeel + CRONA against the soil-dwelling larva

• Reduction of fumonisin and aflatoxin mycotoxin loads through removal of insect entry wounds plus a Bacillus antifungal protocol

Typical scenarios:

• County-, state-, or province-scale deployment across corn belts (US Corn Belt, China Northeast, Brazil Mato Grosso and Cerrado)

• In-row soil-pest control at sowing

• Export-grade corn under EU and FDA mycotoxin compliance

• Integration with full nutrient supply via Arbok-URIA, Arbok-Potash, Arbok-Phosphate, and CRONA

Industries and users:

• National agriculture ministries (USDA, MARA in China, MAPA in Brazil)

• Large farm cooperatives and contract-farming operators

• Pest-control service operators

• Grain traders subject to mycotoxin export standards

Scale:

• USA: ~35 million ha

• China: ~43 million ha

• Brazil: ~22 million ha

• Corn trio total: ~100 million ha (~65% of world corn production by volume)

Operating Principle

The system uses two physically distinct delivery modes against the same physico-chemical target — the chitin cuticle — at two life stages of the pest, and pairs the result with a Bacillus antifungal protocol and a local nutrient line.

Layer 1 — Foliar Repeel:

• Fine acid mist (30–50 micron droplets) from drones or sprayers

• Settles on both leaf surfaces, in the whorl, and on the silks

• Active complex (Repeel TRINITY, a proprietary multi-acid mixture) penetrates the chitin cuticle, irritates sensory receptors without killing the insect

• Pest leaves the field within 3–6 hours; activity ceases within 24 hours

• Targets: fall armyworm (whorl), corn borer (above-ground), adult rootworm (silk, leaves)

Layer 2 — Soil TEG-Repeel + CRONA:

• Thermal Expanded Graphite (TEG) — a graphene-like material of Arbok's own development and production, with very high specific surface area, high absorption capacity, and high electrical conductivity — is impregnated with the Repeel TRINITY acid complex and applied at 15–40 kg/ha in-row at sowing or in inter-row treatment

• In soil, particles act as a controlled-release reservoir; moisture and root exudates gradually liberate the acid complex

• Diabrotica larvae moving and feeding on roots contact the particles; Repeel penetrates the larval chitin and produces irritation plus physico-chemical damage to the integument

• Larvae stop feeding, lose mobility, and die

• Optional CRONA pulse pass: the highly conductive TEG amplifies a directed electrical pulse, delivering a chemical-plus-electric double effect that fully halts root-system damage

Layer 3 — Bacillus antifungal:

• Bacillus subtilis and amyloliquefaciens biocontrol against Fusarium and Aspergillus

• Combined with surface Repeel that acts against spores

• Result: reduction in ear-rot incidence and in fumonisin and aflatoxin contamination

• Doubly reinforced by Layer 1 (foliar Repeel) which prevents the insect entry wounds through which Fusarium and Aspergillus invade

Layer 4 — Nutrition:

• Arbok-URIA: local urea from organic waste, no natural gas dependence

• Arbok-Potash: potassium carbonate from biomass combustion ash

• Arbok-Phosphate: phosphorus from phosphate-plant wastewater

• CRONA: in-field electrical-pulse mobilization of bound soil N/P/K and nitrogen fixation from air

Limitations:

• Weeds (~40% of attainable loss, the largest block) are NOT addressed — separate herbicide-tolerant systems required

• Foliar Repeel requires regional-scale (not point-farm) deployment to prevent pest displacement to neighboring fields

• Soil TEG-Repeel is local to the treated row and does not depend on regional scale

• World corn area: ~165 million ha

• Corn trio (USA, China, Brazil): ~100 million ha, ~65% of world production by volume

• Corn price March 2026: ~$213/t (volatile)

Addressable share:

• ~25% of attainable yield (insect + virus + fungal) across the trio

• Recovered value at scenario: $41–63 billion/year for the trio, up to $65 billion in the upper case

• Plus mycotoxin compliance value for the grain that does reach market

Typical Project Economics

Foliar Arbok-Repeel cost: ~$30–100/ha per season

Soil TEG-Repeel: 15–40 kg/ha (small per-ha addition)

Combined cost band: 5–7 times cheaper than conventional chemistry

Combined recovery: ~25% of attainable yield

Recovery per hectare: 1.4–2.75 t/ha depending on country yield

Per-hectare recovered value (three scenarios):

• Baseline 2026 ($210/t): $290–580

• Moderate 2027 ($250/t): $350–690

• Shock 2027 ($320/t): $450–880

National aggregates:

• USA (35 million ha): $20–31 billion across scenarios

• China (43 million ha): $14–22 billion

• Brazil (22 million ha): $6–10 billion

• Corn trio combined: up to ~$65 billion/year against ~$3 billion product cost (100 million ha × $30 foliar baseline)

System ROI: 10–29× across scenarios.

Price scenarios:

• Baseline 2026: ~$210/t

• Moderate 2027 (trade tension): ~$250/t

• Shock 2027 (drought + trade): $320/t and above (2012 and 2022 dry-year peaks went to $300–330)

Risk Factors

• Weeds (~40%, the largest single loss block) are outside the system scope — separate herbicide-tolerant systems required

• Bt resistance is advancing fast; the foliar Repeel mechanism is intrinsically resistance-proof, but the conventional control regimes being replaced will resist transition for institutional reasons

• Regulatory clearance pathway (EPA, MARA, MAPA, EU MRL — 18–36 months) for both foliar Repeel and soil TEG-Repeel as separate registrations

• Sub-regional deployment of the foliar layer drives pests to neighboring untreated fields; provincial- or state-scale rollout is operationally required

• Soil layer is more forgiving of sub-regional deployment because larvae do not migrate

• Corn-specific field validation on Spodoptera, Ostrinia, and Diabrotica still pending

• Arbok is a technology institute and does not run operational registration directly — government bodies and private partners must build the regulatory bridge (BOOM terms available)
