What type of fungicide is PCNB?

PCNB, or Pentachloronitrobenzene, is classified as a long-lasting seed, bulb, corn, and soil fungicide. Its formulation allows for extended residual activity in the soil, making it effective in preventing and controlling a wide range of fungal diseases in various agricultural settings, particularly seeds and bulbs. This characteristic sets it apart from quicker-acting fungicides, which may not provide prolonged protection and often focus on foliar applications rather than root or soil treatments.

PCNB's broad-spectrum capabilities allow it to effectively target many harmful pathogens, making it suitable for a variety of crops and purposes. This longevity and versatility make it a preferred choice for farmers looking to protect their crops from fungal threats throughout the growing season.
