Do NOT use this product for woodland or forest management.

PRODUCT SPECIFIC USE DIRECTIONS

This product is intended to be applied by PROFESSIONAL APPLICATORS ONLY for insect control on listed Vegetable Transplants grown outdoors or indoors, annual and perennial Ornamental and Flowering Plants, and Non-bearing Deciduous and Evergreen Fruit and Nut Trees, Shrubs and Vines. Non-bearing means crops that will not produce a harvestable raw product in the season that product is applied.

For control of listed insect pests, apply as a foliar broadcast spray to obtain thorough and uniform coverage of the plants or via basal bark or injection treatment. When making foliar broadcast applications, this product must be mixed in sufficient water to assure complete coverage based on the size and amount of plant foliage. Make applications as soon as pest pressure thresholds are reached and at least six hours must elapse prior to applying overhead irrigation. Do NOT allow anyone other than applicators to enter the treatment area during application. If more than one application will be made, refer to the Resistance Management section of this label for additional information.

Foliar Broadcast Sprays

Mix this product with sufficient water and apply as a foliar spray to obtain thorough and uniform coverage of the plants. Choose a finished spray volume appropriate for plant size and amount of foliage to provide thorough coverage throughout the canopy.

Tank Mix Instructions

This product has been shown to be compatible with many other insecticides and adjuvants; however, test specific tank mixes for compatibility prior to use. In addition, because of the large number of plant varieties it is impossible to test every one for safe use; therefore, conduct safety tests on a few plants prior to widespread application.

ORNAMENTAL AND FLOWERING PLANTS

Base application timing on the pest pressure and in consultation with local agricultural experts. Test any surfactants used with this product prior to widespread use to verify plant damage will not occur. For optimal pest control, thorough crop coverage is essential and use whatever water volume is needed to ensure thorough coverage. Monitor pest densities to determine if application is necessary. Consult local extension experts for thresholds.

Use the higher rate in the range when pest pressures are severe.

Questions & Answers

Have a question about this product?
  
Q
How many ounces per gallon do you recommend for Quasar 8.5 SL?

North Texas DFW Area. Black bark scale on Crape Myrtles

A

According to the Quasar 8.5 SL Product Label: for control of black scale and other forms of scale and insects on ornamentals you would apply 8.5-16.5 fluid ounces of this product per 100 gallons. This comes out to 0.08 to 0.165 oz per gallon for ornamental applications.  If you are planning to do a bark banding treatment for the scale you would apply 12.5-25.3 fluid ounces per gallon of water in mid Spring between bud break and full leaf expansion.
