Rigid Boost
Rigid Boost strengthens stems and improves lodging and wind resistance. Silica with potassium, phosphorus and organic acids builds structural rigidity so crops stand up to weather and carry their load without collapsing.
Structural-strength supplement · Pre-harvest application, Anti soft-rot.

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.
Structural-strength supplement from Vegalab Crop Science, powered by Si, K, P, N + organic acids. Rigid Boost targets Stem strength, lodging resistance, wind tolerance.
A balanced P-K fertilizer with calcium and silicate applied pre-harvest to firm fruit and resist soft rot. Cell-wall structure tightens; post-harvest shelf life extends.

Why does stem strength matter?
Lodging - when stems bend or collapse under their own load or in wind and rain - causes direct yield and quality loss and makes harvest harder. Heavily fruiting or tall crops are especially vulnerable. Building structural strength into stems before peak load and weather exposure keeps the crop upright and productive.
How does Rigid Boost work?
Rigid Boost (1-4-4, with Ca 2%, Si 1%) combines silica with potassium, phosphorus and organic acids. Silica reinforces cell walls and stems, while potassium and phosphorus support structural growth and water regulation. The result is improved stem strength, lodging resistance and tolerance to wind, so plants stay standing as they carry fruit and grain.

Builds rigidity progressively, before the crop faces peak load and weather exposure.
Always read and follow the applicable product label.
Apply as a foliar spray through structural growth, building rigidity progressively before the crop faces peak load and weather exposure. As with silica generally, regular applications across the growth phase are more effective than a single late dose, because the reinforcement is laid down over time.
Which crops is it for?
Rigid Boost has been tested on strawberries, tomatoes, stone fruit and berries - crops where stem and structural strength protect both yield and ease of harvest. It is useful wherever heavy fruit load or exposed conditions make collapse a risk.
What roles do silica and calcium play?
Silica provides the physical reinforcement in cell walls and stems, while the calcium and balanced nutrients support cell-wall integrity and steady structural growth. Together they make tissue stiffer and more resilient, which is what lets the crop bear its load and resist wind and lodging.
