Tiger-Sul introduces Tiger Greening Guard – Citrus Mix with a new, improved formulation of 64% Sulphur, 6% Manganese, 6% Zinc, 3% Iron with 1% added Boron. Research is ongoing by a state university in Florida in which Tiger-Sul has, and continues to, support citrus greening research. The initial results indicate Tiger Greening Guard provides key components (soil pH reduction and micronutrient availability) in a system of horticultural practices against citrus greening (HLB). Tiger Greening Guard’s acid forming technology and consistent pastille distribution enhances feeder root uptake of sulphur and other nutrients. It lowers soil pH to reduce stress, and its control release properties optimize nutrient uptake to boost plant health.
