It provides the same control as Strobe Pro Fungicide, only now in granular form. It is formulated with two combination spectrum Azoxystrobin and Propiconazole. Azoxystrobin interferes with the normal respiration of the fungus and Propiconazole is a known DMI’s to help prevent cell membrane from forming. Use for treatment against leaf spots, patch diseases, stem, foliar and root diseases, fairy rings, anthracnose, molds, mildews and rusts of turfgrass. Apply by drop or rotary broadcast granular spreader on lawns, golf courses, and landscape areas. The product comes in a 30-pound bag.

DIRECTIONS FOR USE

Not for use on turf being grown for sale or other commercial use as sod, or for commercial seed productions, or for research purposes.

PRECAUTIONS

Bermudagrass can be sensitive to Strobe Pro G.

RESTRICTIONS

  • Do not apply more than 19.2 lb. product/1000 sq. ft./calendar year. 
  • Apply by ground application only. 
  • Do not graze or feed clippings from treated turf areas to animals.
  • Do not apply when weather conditions favor product blowing from treated areas to nontarget aquatic habitat.
  • Do not exceed 3 lb. product/1,000 sq. ft. every 30 days on any variety of bermudagrass. In Florida, do not apply Strobe Pro G to bermudagrass golf course greens when temperatures exceed 90 degrees.
  • Do not use on turf being grown for sale or other commercial use as sod, or for commercial seed production, or for research purposes.

ATTENTION

Strobe Pro G is extremely phytotoxic to certain apple varieties. Extreme care must be used to prevent injury to apple trees (and apple fruit). DO NOT spread Strobe Pro G where granules may reach apple trees. 

RESISTANCE MANAGEMENT

For resistance management, please note that Strobe Pro G contains both a Group 11/Azoxystrobin and Group 3/Propiconazole fungicide. Any fungal population may contain individuals naturally resistant to Strobe Pro G and other Group 11 or Group 3 fungicide. A gradual or total loss of pest control may occur over time if these fungicides is used repeatedly in the same field. Appropriate resistance-management strategies should be followed.

To delay fungicide resistance, take one or more of the following steps:

  • Rotate the use of Strobe Pro G or other Group 11 and Group 3 fungicide within a growing season sequence with different groups that control the same pathogens.
  • Use tank mixtures with fungicide from a different group that are equally effective on the target pest when such use is permitted. Use at least the minimum application rate as labeled by the manufacturer. 
  • Adopt an integrated disease management program for fungicide use that includes scouting, uses historical information related to pesticide use, and crop rotation, and which considers host plant resistance, the impact of environmental conditions on disease development, disease thresholds, as well as cultural, biological and other chemical control practices. 
  • Where possible, make use of predictive diseases models to effectively time fungicide applications. Note that use predictive models alone is not sufficient to manage resistance.
  • Monitor treated fungal populations for resistance development.
  • Contact your local extension specialist or certified crop advisor for any additional pesticide resistance-management and/or IPM recommendations for specific crops and pathogens. 
  • For further information or to report suspected contact your local retailer or your local university extension specialist.

If repeated application is necessary, this statement may be modified as follows: “Avoid application of more than 2 and consecutive applications of Strobe Pro G or other fungicides in the same group in a season.”

If no resistance specifications on the number of applications is specifies in the direction for use, follow the specifications in the table below.

If planned total number of fungicide applications per crop is: 1 2 3 4 5 6 7 8 9 10 11

12

Solo Qol fungicide applications 1 1 2 2 2 2 2 3 3 3 3 4
Qol fungicide applications in mixture (formulated) 1 2 2 2 2 3 3 4 4 5 5 6

In situations requiring multiple applications, develop year-long programs for Group 11 (Qol) fungicides. In crops where two sequential Group 11 fungicide applications are made, they must be alternated with two or more applications of a fungicide that is not in Group 11. If more than 12 applications are made, observe the following guidelines:

  • When using a Qol fungicide as a solo product, the number of applications must be no more than 1/3 (33%) of the total number of fungicide applications per year.
  • For Qol mixes in programs in which tank mixes or premixes of Qol with mixing partners of a different mode of action are utilized, the number of Qol containing applications must be no more than ½ (50%) of the total number of fungicides applications per year.
  • In programs in which applications of Qol are made with both solo products and mixtures, the number of Qol containing applications must be no more than (50%) of the total number of fungicides applied per year.

If a Group 11 fungicide is applied to the seed or soil, do not make another application with a Group 11 fungicide for at least 3 weeks.

APPLICATION INSTRUCTIONS

Apply Strobe Pro G at rates and timings as described in this label. Strobe Pro G may be applied with all types of spreader equipment commonly used for making ground applications excluding bellygrinder equipment. Proper adjustments and calibration of application equipment to give good coverage is essential for good disease control. The higher rates in the rate range and/or shorter application intervals may be required under conditions of heavy infection pressure, highly susceptible varieties, or when environmental conditions conducive to disease exist.

TURF

Strobe Pro G is specified for control of certain pathogens causing foliar, stem, and root diseases, including leaf and stem blights, leaf spots, patch diseases, mildews, anthracnose, fairy rings, molds, and rusts of turfgrass plants. Strobe Pro G may be used to control certain diseases on turf in golf courses, lawns and landscapes areas around residential, institutional, public, commercial and industrial buildings, parks, recreational areas and athletic fields.

Retreatment Intervals: Strobe Pro G must be applied prior to disease development. Repeat applications at specifies intervals for as long as required.

RESTRICTIONS

  • Do not apply more than 19.2 lb. product/1000 sq. ft./calendar year.
  • Apply by ground application only.
  • Do not graze or feed clippings from treated turf areas to animals.
  • Do not exceed 3 lb. product/1,000 sq. ft. every 30 days on any variety of bermudagrass. In Florida, do not apply Strobe Pro G to bermudagrass golf course greens when temperature exceeds 90 degrees.

For use in the establishment of turfgrass from seed or in overseeding of dormant turfgrass:

Strobe Pro G may be used for control of certain turfgrass diseases associated with turfgrass establishment from seed. Strobe Pro G may also be used during overseeding of dormant turfgrass.

Strobe Pro G may be safely applied before or after seeding or at seedling germination and emergence to ryegrass, bentgrass, bluegrass, and fescue turfgrass types. Optimum application timing is during seeding. See application directions section.

Retreatment Interval: Use the shorted specified application interval and/or use the higher specified rate when prolonged favorable disease conditions exist.

    Best product ever

    By Ray on 06/19/2020

    I spend over $500 each year trying to treat my necrotic ring spot. I've tried Heritage, headway G, ring to green and several others. Strobe Pro G is my far the best product I've ever used for this disease. The lawn has completely filled in and looks healthy. You must fertilize as well and use proper watering recommendations. I wish I had some before and after pics. I know it will come back when the lawn gets stressed or in the fall, it always does. I plan to use this again each time it returns.
