Additional Information

Active Ingredient: Hachi-Hachi SC contains the active ingredient, tolfenpyrad, which is classified by Insecticide Resistance Action Committee (IRAC) in Group 21A, mitrochondrial electron transport inhibitors. Hachi-Hachi SC inhibits the electron transfer system of energy metabolism in the mitochondria of susceptible insects. As a fungicide, the Fungicide Resistance Action Committee (FRAC), recognized Hachi-Hachi SC in group 39. This technology is recognized to affect fungal respiration with no known resistance, confirmed by FRAC.

Formulation: Hachi-Hachi SC is a water-based suspension concentrate (SC) formulation containing 1.31 lbs of tolfenpyrad per gallon. The SC formulation is easy to handle, mix and apply. Hachi-Hachi SC can be mixed with other fertilizers and registered pesticides. For specific directions on tank-mixing with different products, refer to the Hachi-Hachi SC label.

Using Hachi-Hachi SC

Hachi-Hachi SC is currently registered for use on ornamental crops grown in the greenhouse, including cut flowers. Hachi-Hachi SC is active via contact and ingestion, therefore thorough spray coverage is important for optimal control. Apply Hachi-Hachi SC as a foliar spray using sufficient carrier volume to obtain uniform and complete coverage.

For best results, begin applications at the first sign of pressure when pests are immature or at the most susceptible stage. For repeat applications, allow at least 10 days between applications

Hachi-Hachi SC is an ideal IPM tool and is recommended to be used in a programmed rotation with other insecticides with different modes of action. Hachi-Hachi SC should not be applied more than twice during a cropping cycle. Additionally, rates lower than those listed on the label should not be applied.

Hachi-Hachi-SC Crop Tolerance

Hachi-Hachi SC has been tested on a wide variety of common greenhouse crops with no phytotoxic affects. SePRO continues to test additional species for crop sensitivity in an effort to develop a broad, expansive list of tolerant ornamental plants. To minimize plant sensitivity, utilize small droplet producing applicators, avoid pooling of spray solution on the plant and make applications during the cooler part of the day when the plants are under less stress. In all cases, the user should test Hachi-Hachi SC on a small sample of the plants to be treated to ensure satisfaction. Do not apply Hachi-Hachi SC to impatiens, New Guinea impatiens, baby’s breath (gypsophilia), phlox, salvia or poinsettias.
