Stemmer is a bioavailable silicic acid that is readily absorbed by plants, supporting stronger growth and greater tolerance to abiotic stress than traditional silica products, leading to improved crop performance and increased yields. By increasing nutrient mobility, Stemmer improves nutrient and water use efficiency, strengthens plant cell walls, enhances tissue integrity, and promotes stronger, more upright growth. These combined benefits support healthier plant development and help maintain productivity under challenging environmental conditions, including drought, heat, and frost. Stemmer's 100% soluble formulation easily integrates into existing fertility and crop protection programs for easy application and consistent, season-long performance.
- Boosts plant tissue resilience and greenness
- Promotes upright growth and overall vigor
- Improves nutrient and water use efficiency
- Enhances mobility of hard-to-more nutrients like calcium
- Increases tolerance to abiotic stress like salinity, heavy metals, UV radiation, drought, heat, and frost
- 0-hour REI, 0-day PHI

Agitate the product thoroughly before opening. This product MUST be diluted in water before use. Use within 4 hours after dilution. Mix at the dilution rate listed on the label. Stemmer is best used as a foliar spray, but can also be applied to the root zone. Stemmer is best applied frequently with low rates to ensure consistent and prolonged coverage in the plant.
Mixing Directions: Add sufficient water to the clean mixing tank to allow proper agitation. Add the correct amount of Stemmer to tank. Maintain agitation until solution is used. If other pesticides and/or adjuvants are to be added, do so after Stemmer has been thoroughly mixed.
Application Instructions: Apply Stemmer as a drip, in furrow, drench or foliar application at the rates indicated in the rate table on label. Apply a minimum spray volume of 5 gallons per acre but recommend applying the diluted product at 100 gallons per acre. Early use on short term greenhouse crops or begin application at flower initiation. Field crops such as leafy greens and herbs benefit early while fruiting crops application timing should be at flower or new leaf emergence. Stress mitigation is best prior to stress event.
- IN FURROW: Agitate the product thoroughly before opening. Accurately measure and add the recommended dosage to sufficient amount of clean water in appropriate in furrow equipment tank. Apply product in furrow into the seed trench during planting.
- DRIP: Agitate the product thoroughly before opening. Dilute or inject the product to the desired concentration from the rate table on label.
- FOLIAR AND SOIL APPLICATION: Agitate the product thoroughly before opening. Accurately measure and add the recommended dosage to sufficient amount of clean water in application tank to achieve the desired coverage. Foliar application is 5 to 100 gallons per acre; soil application range is 50 to 5,000 gallons per acre for in furrow drip methods.
Environment: For use on protected and open field crops such as; Greenhouse, Shadehouse, Interiorscape, and Nursery. Use on indoor and outdoor food and non-food crops, plants, shrubs, trees and ornamentals. Not for use on row crops including corn, soybean, wheat, barley, canola, cotton, oats, rice and rye
Storage: Keep in original closed container at room temperature, do not freeze

Warning & Toxicities: Stemmer has been tested on numerous plant varieties. However, since Stemmer has not been tested on all plant varieties or in combination with all available tank mixes, BioWorks strongly advises testing Stemmer on a small number of plants to check for adverse plant effects before applying to a larger number of plants.
