Product Description

Fungal soilborne disease can stop seeds from germinating before they even start, but Root Guardian™ has your seedlings' back! Designed for application to seeds, plant roots and soil during planting, Root Guardian protects roots from fungal diseases for up to 3 months, and promotes bigger, faster growing and vigorous root systems. Plus, our bio-fungal formula releases compounds that make nutrients more readily available to plants! The active ingredient is a microbe, Trichoderma harzianum Strain T-22 (KRL-AG2), which, when applied to seeds, transplants, soil, or planting mixes, grows onto plant roots as they develop and provides protection against harmful plant root pathogens. Each package of Root Guardian Biofungicide contains approximately 8 tablespoons of powder.

For seeds, mix 1-3 tablespoons per gallon of water to treat a 25' plant row. Drench the planting furrow before covering the seed with soil.

For transplants, mix 1-3 tablespoons per gallon of water and apply ½ - 1 cup per plant at transplanting.

For new beds, mix 1-3 tablespoons per gallon of water and apply at a rate of 1 gallon per 25 sq. ft.

For established beds or potted plants, mix 1-3 tablespoons per gallon of water and apply at a rate of 1 gallon per 25 sq. ft. of plant bed or ½ - 1 cup per 4-8" diameter pot.
