Armour Boost
Armour Boost is a soluble silica supplement that builds cell-wall rigidity and weather resistance. Foliar-applied potassium silicate is absorbed and deposited in epidermal cell walls, forming a silica barrier that helps crops resist insect probing, frost damage and lodging while improving overall tolerance to abiotic stress.

Pre-harvest and re-entry intervals are restrictions carried on pesticide labels. These products are not pesticides, so neither applies. For comparison, four hours is the shortest re-entry interval a registered pesticide can carry.
Soluble silica supplement from Vegalab Crop Science, powered by Soluble silica · potassium silicate. Armour Boost targets Cell-wall rigidity, frost & insect resistance, lodging prevention.
Soluble potassium silicate is absorbed via foliar uptake and deposited in epidermal cell walls, producing physical rigidity and a silica defensive barrier. Crops resist insect probing, frost damage and lodging; abiotic stress tolerance increases.

What does silica do for a crop?
Silicon is not classed as an essential nutrient, but crops that take it up are measurably tougher. Deposited in the cell walls of leaves and stems, silica acts like internal reinforcement - stiffening tissue, blunting insect mouthparts and forming a physical barrier against fungal penetration. Armour Boost (K 6%, Si 15%) supplies silicon in a soluble, plant-available form so the crop can build that reinforcement where it matters.
How does Armour Boost work?
Applied as a foliar spray, the soluble potassium silicate is absorbed and deposited in epidermal cell walls, producing physical rigidity and a silica defensive layer. The result is greater resistance to insect probing, frost and lodging, plus improved tolerance to drought and other abiotic stress. The potassium component additionally supports water regulation and overall plant vigour.

Silica builds up progressively, so repeated doses beat a single late one.
Always read and follow the applicable product label.
Apply as a foliar spray throughout vegetative growth at 1:1,000 (1 mL/L; 0.5–0.75 L/ha). Silica reinforcement builds up progressively as the plant deposits it, so regular applications across the growth phase work better than a single late dose. Build the structure before the crop faces peak load, weather exposure or pest pressure.
Which crops benefit most?
Armour Boost has been tested on cereals, cucumbers, rice, sugarcane and turf - crops prone to lodging, frost or surface disease, where structural strength and a tougher leaf surface directly protect yield and quality. Cereals and rice especially benefit from the lodging resistance that silica provides.
How does it support stress tolerance and pest resistance?
By stiffening tissue and forming a silica barrier, Armour Boost helps crops resist insect probing and frost while standing up better to wind and lodging. It is not a pesticide, but the physical reinforcement makes plants a harder target and more resilient under abiotic stress - a useful foundation layer in a broader crop-health program.
