Pesticides (40 CFR Part 170). The WPS applies when this product is used to produce agricultural plants on farms, forests, nurseries, or 

greenhouses. 

Keep all unprotected persons out of operating areas or vicinity where there may be drift. Do not enter treated areas without protective 

equipment until sprays have dried. 
USE RESTRICTIONS:

Phytotoxicity 

GWN-1708 has been used successfully on many ornamental plants species. Do not treat new species or varieties without first testing a few

plants on a small scale. Do not apply to roses 

FORMULATION, ROUTE OF EXPOSURE, TYPE OF ACTION 

GWN-1708 is a suspension concentrate formulation that acts by contact to provide rapid knockdown of mites and whiteflies. 

MODE OF ACTION AND RESISTANCE 

GWN-1708 is a METI (mitochondrial electron transport inhibitor) classified as Group 21. To prevent or delay resistance development, only 

apply a single application of GWN-1708 per crop season. If additional chemical control is required, rotate to a product with a different mode of 

action grouping. 

MIXING DIRECTIONS 

Dilution Rate 

Apply GWN-1708 in sufficient water to ensure thorough coverage of foliage. Applications can be made with low or high volume spray 

equipment; however, thorough coverage is required for optimum control. Maintain agitation during mixing. 

Additives 

In general, no additives are necessary for effective use of GWN-1708. 

However, in situations where local conditions such as hard water are a problem, use adjuvants or wetting agents to achieve thorough spray 

coverage. 

GENERAL TANK MIXING INFORMATION 

Phytotoxicity 

The phytotoxic potential of GWN-1708 has been assessed on a wide variety of common ornamental plants with no phytotoxicity observed. 

However, all plant species and their varieties and cultivars have not been tested with possible tank mix combinations, sequential pesticide 

treatments, and adjuvants and surfactants. Local conditions can also influence crop tolerance and may not match those under which testing 

has been conducted. Therefore, before using GWN-1708, test the product on a sample of the crop to be treated to ensure that a phytotoxic 

response will not occur as a result of applications. 

Compatibility Test for Mix Components 

Before mixing components, always perform a compatibility jar test. 

For 20 gallons per acre spray volume, use 3.3 cups (800 ml) of water. For other spray volumes, adjust rates accordingly. Only use water from 

the intended source at the source temperature. 

Add components in the sequence indicated in the Mixing Order (see below) using 2 teaspoons for each pound or 1 teaspoon for each pint of 

recommended label rate per acre. 

Always cap the jar and invert 10 cycles between component additions. 

When the components have all been added to the jar, let the solution stand for 15 minutes. Evaluate the solution for uniformity and stability. 

The spray solution should not have free oil on the surface, nor fine particles that precipitate to the bottom, nor thick (clabbered) texture. If the 

spray solution is not compatible, repeat the compatibility test with the addition of a suitable compatibility agent. If the solution is then 

compatible, use the compatibility agent as directed on its label. If the solution is still incompatible, do not mix the ingredients in the same tank. 

Mixing Order 

1) Water: Begin by agitating a thoroughly clean sprayer tank half full of clean water. 

2) Water-dispersible products: (dry flowables, wettable powders, suspension concentrates, or suspo-emulsions) 

3) Emulsifiable concentrates

4) Water Soluble Products 

5) Water-soluble additives

6) Remaining quantity water

Maintain constant agitation during application.
APPLICATION DIRECTIONS 

Application Equipment 

Application can be made with the following types of low or high volume spray equipment: [list general types of equipment such as machine 

ground spray application (open cab groundboom), ground spray application (open cab airblast sprayer), high pressure hand wand sprayer, 

backpack sprayer. 

Constant Agitation Before and During Application 

Shake well before using and frequently while applying. If agitation is stopped for an extended period of time, the spray solution must be 

thoroughly re-mixed prior to further use. 

Importance of Coverage 

Thorough coverage is required for optimum control 

Application Rates 

Apply GWN-1708 at rates in Table 1. Do not apply during conditions when product will drift to all other crops and non-target areas.
