fertilome F-STOP Specialty Fungicide is a systemic, protectant and curative fungicide recommended for the control of listed turfgrasses disease in established lawns and ornamental turfs, including golf course fairways, roughs, trees and greens. Optimum disease control is achieved when this product is applied to established turfgrasses in a regularly scheduled preventative program.
fertilome F-STOP should be used in conjunction with turf management practices that promote good plant health and optimum disease control. The key to selecting a fungicide is the proper diagnosis or the organism causing the disease. Diagnostic kits, extension experts or other identification methods should be used when developing disease control strategies.
Optimum disease control is achieved when fertilome F-STOP is applied in a preventative disease control program at a rae of 4 to 8 lbs per 1,000 square feet. See the following table for specific application rates for various diseases.
For the control of Root and Crown Rot, this product must be watered-in using a minimum of 3 to 4 gallons of water per 1,000 square feet.
Under conditions that are favorable for disease development, the interval between applications of fertilome F-STOP should be reduced.
Unless otherwise specified, when disease pressure is high or when used as a curative, use higher rates of fertilome F-STOP and shorter application interval. Under light to moderate disease pressure, apply fertilome F-STOP at the low use rate and/or longer application intervals.
Apply fertilome F-STOP uniformly using an appropriate fertilizer spreader. Calibrate the spreader before application as calibration may change with spreader age and use, walking speed and evenness of terrain. To calibrate the spreader, weigh out the amount of product necessary to treat an area of 800 square feet. using the suggested spreader setting provided by the manufactureer of from the table below, apply to a pre-measured area of 500 square feet (5 x 100 square feet) area. Weigh back product remaining in application equipment and adjust the spreader as necessary to give the correct rate of delivery for the measured area.
To avoid pick-up, lightly irrigate treated areas soon after application.
On short cut Bentgrass (1/2" or less) when temperatures are above 80°F; apply only to dry foliage.

Apply ferti•lome® F-STOP™ with drop or rotary spreaders designed to apply granules. Avoid the use of spreaders that would apply this product in narrow rows or concentrated bands. Before each application, calibrate the spreader according to the equipment manufacturer’s directions such that the spreader delivers the recommended application rate. Apply this product uniformly over the lawn or ornamental turf area. A more uniform application can be made by spreading half of the required amount over the area in a given direction and then applying the remaining half at a right angle to the previous direction. Avoid streaking, skips or overlaps during application. Check equipment frequently to ensure equipment is functioning properly and applying uniform distribution of granules.
