GENERAL INFORMATION 

ARENA 50 WDG - MC111004 

Page 4 of 7 

ARENA 50 WDG is a broad spectrum insecticide, for control of a wide spectrum 

of insects infesting turfgrass. When applied as directed, ARENA 50 WDG 

provides excellent and long residual insect control. 

GENERAL RESTRICTIONS AND LIMITATIONS 

1. DO NOT use a foliar application of clothianidin (ARENA 50 WDG) 

following an in-furrow or soil application of clothianidin (CELERO 16 

WSG). 

2. Regardless of formulation or type of application (soil or foliar) on 

turfgrass, DO NOT apply more than a total of 0.4 Ibs active ingredient, 

clothianidin per acre per season. 

3. If the maximum season limit of clothianidin as mentioned above has been 

applied and pest populations require additional treatments, use another 

registered pesticide that is not in the neonicotinoid class of chemistry. 

RESISTANCE MANAGEMENT 

ARENA 50 WDG contains a Group 4A2 insecticide. Insect biotypes with acquired 

resistance to Group 4A2 may eventually dominate the insect population if Group 

4A2 insecticides are used repeatedly in the same field or in successive years as 

the primary method of control for targeted species. This may result in partial or 

total loss of control of those species by ARENA 50 WDG or other Group 4A2. 

To delay insecticide resistance consider: 

• Avoiding the consecutive use of other Group 4A2 insecticides that have a 

similar target site of action, on the same insect species. 

• Using tank-mixtures or premixes with insecticides from a different target 

site of action Group as long as the involved products are all registered for 

the same use and have different sites of action. 

• Basing insecticide use on a comprehensive IPM program. 

• Monitoring treated insect populations for loss of field efficacy. 

• Contacting your local extension specialist, certified crop advisors, and/or 

manufacturer for insecticide resistance management and/or IPM 

recommendations for the specific site and resistant pest problems. 

• For further information or to report a suspected resistance, you may 

contact Arvesta Corporation at 1-866-761-9397. 

2 Not all members of this class have been shown to be cross-resistant. Different resistance 

mechanisms that are not linked to target site of action, such as enhanced metabolism, are 

common for this group of chemicals. Alternation of compounds from different subgroups within 

this class may be an acceptable part of an integrated pest management program. 

PLANT TOLERANCE 

Neither the manufacturer nor the seller has determined whether or not ARENA 

50 WDG can be used safely on all cultivars of plants listed on the label. ARENA 

50 WDG has been tested on many cultivars with no phytotoxicity observed at 

label rates. Since all plant species and their varieties and cultivars have not 

been tested for tolerance, it is recommended that a small number of plants be 
f 

ARENA 50 WDG - MC111004 

Page 5 of 7 

sprayed to make certain that no phytotoxicity occurs, prior to any large scale 

application to plants. The end user assumes all risks arising from application of 

ARENA 50 WDG in a manner inconsistent with its labeling. 

COMPATIBILITY OF MIXTURES 

To obtain broad-spectrum pest control, ARENA 50 WDG can be tank-mixed with 

other pesticides. 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. The user should conduct a spray mix 

compatibility and phytotoxicity trial under local conditions to ensure compatibility 

prior to any large-scale use. 

PREPARATION OF SPRAY SOLUTION 

Begin with clean equipment. Add sufficient clean water to the spray tank for onehalf of the mix load. Start tank agitation. Add and properly suspend the 

necessary amount of ARENA 50 WDG before adding any other products. 

Agitate to ensure thorough mixing while adding the remaining required water. A 

high quality wetting agent or other spray adjuvant, approved for use on your crop, 

may be added to spray solutions according to the manufacturer's use 

instructions. ARENA 50 WDG should be properly suspended and diluted prior to 

the addition of any adjuvant. Consult the adjuvant label or manufacturer for crop 

tolerance and safety information when used with this product. Maintain agitation 

during mixing and application. DO NOT allow the spray mixture to stand without 

agitation. Apply with properly calibrated spray equipment. If agitation is stopped 

for any reason, the spray solution must be thoroughly re-mixed prior to any 

further use. 

APPLICATIONS 

APPLICATION TO TURFGRASS 

ARENA 50 WDG can be used as directed on grass grown in industrial, 

commercial and residential landscapes such as, but not limited to golf courses, 

home lawns, airports, cemeteries, parks, playgrounds, athletic fields and 

commercial sod farms. 

ARENA 50 WDG has sufficient residual activity to provide high levels of control 

when applications are made preceding or during the egg laying activity of the 

target pests. The need for an application can be based on historical monitoring of 

the site, previous records or experiences, current season adult trapping or other 

methods. Optimum control will be achieved when applications are made prior to 

egg hatch of target pests, followed by sufficient irrigation or rainfall to move the 

active ingredient through the thatch. 

Apply ARENA 50 WDG in sufficient water to provide optimal distribution in the 

treated area. The use of properly calibrated equipment normally used for the 

application of turfgrass insecticides is required. Use equipment which will 
( 

ARENA 50 WDG - MC111 004 

Page 6 of7 

produce a uniform, coarse droplet spray, using a low pressure setting to 

eliminate off target drift. Check calibration periodically to ensure that equipment 

is working properly. 

Avoid mowing turfgrass until after irrigation or rainfall has occurred so that 

uniformity of application will not be affected.
