LALRISE BOOST is a microbial growth promoter

LALRISE BOOST® is a unique PGPR utilizing the active ingredient Delftia acidovorans which is active in the soil and rapidly colonizes the root zone of a plant. Treated plants have healthier roots that access more water and nutrients and drive an early plant root set, treated plants will also have a shorter lag phase and a longer phase of rapid growth. For ease of application, LALRISE BOOST can be tank-mixed and applied with the first post-emergent application.

Delftia acidovorans is attracted to root exudates and will move toward growing roots and colonize the root zone. The bacteria positively impacts plant root growth; this ultimately supports higher yields, depending upon environmental and soil conditions.

Key benefits

Delftia acidovorans works by:

  • Stimulating root and root hair development, helping the plant access more water and nutrients in limiting environmental conditions
  • Aggressively colonizes roots and out-competes other soil bacteria and fungi
  • Making more sulfur available to the plant. LALRISE BOOST has a synergistic effect with sulfur fertilizers. It enhances mineralization to access the 95% of soil sulfur pool tied to organic matter. The yield of LALRISE BOOST treated plants with sulfur fertilizers is greater than either input alone.

  • Apply LALRISE BOOST in the evening, in cooler temperatures. Do not apply LALRISE BOOST in hot, dry conditions.
  • Recommended water rates assist Delftia acidovorans in entering the soil. Reducing the water rate is not recommended.
  • If tank mixing LALRISE BOOST with a recommended herbicide, add the bacterial solution last and ensure it is applied to the appropriate herbicide tolerant system.
