Terrazole L Fungicide

Terrazole L Fungicide, manufactured by OHP, is a reliable and effective commercial fungicide solution for managing soil-borne fungal diseases in ornamental plants and turf. 

The power behind this emusifiable concentrate is etridiazole, a fungicide classified as FRAC Group 14. Etridiazole works by inhibiting the development of fungal cell membranes, effectively stopping the pathogen before it can damage plant tissue.

Terrazole L Fungicide systemic action, versatility in application methods, and targeted control of Pythium and Phytophthora species make it an invaluable tool for growers and turf managers. By integrating Terrazole L into your disease management program, you can ensure healthier plants and more resilient turf.

Tools Needed

It can be applied with a handheld pump sprayer, backpack sprayer, or chemigation system. 

How to Use

• Step 1: Determine how much Terrazole L Fungicide to use by measuring the square footage of the treatment area. Find the square footage by measuring the treatment area's length and width in feet, then multiply them together (length X width = square footage). To treat golf course turf (tees and greens), mix 1.5 to 3 fl. oz. of Terrazole L Fungicide in 2 to 5 gallons of water and apply to 1000 sq. ft. The application rates for ornamentals will vary based on pot size. For example, a container that is 4 inches will require 2 fl. oz. of product. For bedding plants, flowering plants, foliage plants, and woody ornamentals, use 2.7 to 7 fl. oz. of product with 100 gallons of water. Refer to the product label for specific application rates and restrictions. 
• Step 2: Fill your sprayer tank with half the amount of water, add the proper amount of product, then pour in the last half of the water. Close the tank lid and shake until mixed. For chemigation systems, fill according to the manual instructions. 
• Step 3: For turf, spray evenly across the treatment area until wet, but not to the point of runoff. For ornamental foliage, apply as a drench around and on the foliage. To improve penetration of the fungicide, the drenching must be followed with an additional quantity of water equal to at least half the volume of the fungicidal drench, applied either by sprinkling or irrigation.

When the chemigated area is open to the public, such as golf courses or retail greenhouses.
