  • Overview
    • This formulation contains nitrogen, phosphorous, potassium and potassium phosphite to supply foliar potassium and phosphite for improved plant health. Phosphites stimulate upregulation of plant defense mechanisms like antioxidant and phytoalexin production, and phosphite use is an essential tool for IPM disease management of pythium and anthracnose.
    • This product has been extensively researched with documented and proven results from Rutgers University and Virginia Tech University. Unique to PK Plus, our phosphite-containing foliar product also contains nutritional P (phosphate) unlike most, if not all other, phosphite materials on the market today.
    • The inclusion of N, P, K and micronutrients makes PK Plus the superior phosphite product available to the turf manager. It also is second to none in mixing capability, compatibility and turf safety. PK Plus also has been field tested for many years and has proven to be an essential product for a summer foliar program. Phosphites must be applied sequentially and preventively prior to environmental stress to be effective.
