use summary


Engulf GHN may be applied to ornamental foliage for knockdown and residual control of mites on ornamental plants (including ornamental bulb crops, bedding plants, ornamental foliage and flowering plants, perennials, shrubs and trees). The plants may be grown in the ground or in pots. Engulf GHN  provides residual control for up to 28 days. Use the lower listed rates when mite pressure is low or for preventative applications; and use the higher rates when mite pressure is severe or for residual control. Apply as soon as mites appear. 

Mix 2-4 fluid ounces of this product per 100 gallons of water (1/8 – 1/4 teaspoon per gallon of water). Apply 1-4 quarts of the mixture per 100 square feet (100-400 gallons per acre) to the foliage using ground spray equipment (including, air blast, compressed air, ground boom, hose-end and hydraulic sprayers). The spray volume used is dependent on the size of the plants being treated, with larger plants requiring greater spray volumes. 

Coverage of ornamentals with hard-to-wet foliage may be improved by using an adjuvant to the spray mixture. Silwet 77® or Sylgard 309® at a rate of 4 ounces per 100 gallons of water has been found to be effective. As with any tank mixture, test the compatibility and safety of any adjuvants in a small-scale trial prior to widespread use.

DO NOT apply Engulf GHN more than two times per calendar year.

DO NOT apply more than 16 fluid ounces of this product per acre per calendar year.

DO NOT apply this product by aerial application.


Use Restrictions

DO NOT plant another crop within 30 days after last application of this product. Planting within 30 days of last application increases the likelihood of bifenazate residues appearing in rotational crops.

DO NOT exceed the maximum amount of bifenazate allowed per crop per calendar year. This applies to all product(s) containing bifenazate that are applied to the crop in a calendar year.

DO NOT use adjuvants in tank mixtures that will be applied to greenhouse tomatoes.

DO NOT apply to greenhouse tomatoes within 3 days of harvest (3-day PHI).

See label for complete application rates and recommendations.
