GENERAL INFORMATION

DOU ZHAN WEI® is an insecticide that controls aphids and reduces whiteflies population on ornamental plants in greenhouses and controls aphids on outdoor ornamentals, greenhouse tomatoes and greenhouse peppers and Balsam twig aphid on Christmas trees.


MODE OF ACTION

DOU ZHAN WEI® has a mode of action that controls aphids and reduces populations of whiteflies by stopping their feeding activity. These insects stop feeding within hours, but remain on the plant for a short time (2-4 days). DOU ZHAN WEI® has residual activity in the plant and will control aphids and reduces populations of whiteflies that move onto the plant after spraying.

Suitability for Integrated Pest Management Programs

DOU ZHAN WEI® has a low toxicity to beneficial insect (including honeybees and bumblebees) and mite populations. However, do not apply DOU ZHAN WEI® directly to the bees that are actively foraging in the field. Do not apply when flowering weeds are present.


Use Restrictions

Greenhouse Use

Do not apply more than 20 g/100L per application.

Do not exceed two applications (2 x 20 g product /100L water) per crop cycle.


Outdoor Use

Do not apply more than 20 g/100L per application.

Do not exceed three applications (3 x 20 g product /100L water) per year.


PHYTOTOXICITY

DOU ZHAN WEI® has been evaluated for phytotoxicity on many greenhouse, nursery, and ornamental plants. All plants tested under university research and commercial production conditions have not shown phytotoxicity at labeled rates of DOU ZHAN WEI®. While many species and cultivars have been tested, a small group of each species and cultivar should be evaluated for phytotoxicity two weeks prior to making applications to the entire crop. Applications should not be made to poinsettia after bract formation.


APPLICATION PROCEDURES:

• Use sufficient water to provide thorough, uniform coverage.

• Use sprayer nozzles that provide accurate, uniform application and medium-sized

droplets.

• Calibrate sprayer from manufacturer's instructions or provincial's recommendations to ensure delivery of adequate spray volume per unit area.

• Applications using sufficient water volume to provide thorough and uniform coverage generally provide the most effective aphid pest control.


MIXING

Prepare no more spray mixture than is needed for the immediate operation. Thoroughly clean spray equipment before using this product. Vigorous agitation is necessary for proper dispersal of the product. Maintain maximum agitation throughout the spraying operation. Do not let the spray mixture stand overnight in the spray tank. Flush the spray equipment thoroughly following each use and apply the rinsate to a previously treated area.

Add 1/2 of the required amount of water to the mix tank. With the agitator running, add the and cultivar should be evaluated for phytotoxicity two weeks prior to making applications to the entire crop. Applications should not be made to poinsettia after bract formation.

Chemigation

Do not apply this product through any type of irrigation system.


APPLICATION DIRECTIONS – GREENHOUSE USE

When target pests appear and conditions do not favor drift beyond the target area, apply foliar spray mixture uniformly to all plant surfaces, particularly the stem and leaf undersides, to point of runoff. Avoid spray overlap that could cause phytotoxicity. Use the following rates and re- treatment intervals.

Whiteflies including:
Silverleaf Whitefly

Application at the
recommended rate can contribute to whitefly IPM programs by reducing whitefly infestation levels, without harming whitefly parasitoids
and predators.


Restrictions:

1. Do not apply more than 20 g product /100 L per application.

2. Do not exceed two applications (2 x 20 g/100 L) per crop cycle.

3. For ornamentals grown for cut flower production (eg, rose, chrysanthemums, gerbera) or those requiring significant foliar contact during cultivation (eg, pinching, pruning, hand harvesting), do not apply more than three applications per greenhouse per year.

Resistance Management Statement

Any insect population may contain individuals naturally resistant to DOU ZHAN WEI®. The resistant individuals may dominate the insect population if this group of insecticides are used repeatedly in the same fields. Other resistance mechanisms that are not linked to site of action but are specific for individual chemicals, such as enhanced metabolism, may also exist. Appropriate resistance-management strategies should be followed.


TO DELAY INSECTICIDE RESISTANCE:

Where possible, rotate the use of DOU ZHAN WEI® with different groups that control the same pests in a field/greenhouse.

Do not apply more than maximum amount of product listed in the label and avoid consecutive sprays of DOU ZHAN WEI® or other insecticides in the same group in a season.

Use tank mixtures with insecticides from a different group when such use is permitted.

Insecticide use should be based on an IPM program that includes scouting, record keeping, and considers cultural, biological and other chemical control practices.

Monitor treated pest populations for resistance development.
