General Information


Some insects are known to develop resistance to insecticides after repeated use. As with any insecticide, the use of the product should conform to resistance management strategies established for the use area.

Widow Insecticide contains a Group 4A insecticide. Insect biotypes with acquired or inherent resistance to Group 4A may eventually dominate the insect population if Group 4A insecticides are used repeatedly as the predominant method of control for targeted species.

The active ingredient in Widow belongs to the neonicotinoid chemical class. Insect pests resistant to other chemical classes have not shown cross-resistance to Imidacloprid. In order to maintain susceptibility to this class of chemistry in insect species with high resistance development potential, it is recommended that for each crop season: 1) only a single, soil application of Widow be made; 2) foliar applications of products from this same class not be made following a long residual, soil application of Widow, or other neonicotinoid products.

Other Group 4A, neonicotinoid products used as foliar treatments include: Actara, Assail, Calypso, Centric, Intruder, Leverage, Provado and Trimax.

Other Group 4A, neonicotinoid products used as soil treatments include: Platinum.

Apply Widow Insecticide as a directed or broadcast foliar spray using properly calibrated ground application equipment as allowed in the specific application section. For insecticidal efficacy, thorough coverage of all target foliage with runoff is necessary. To obtain thorough coverage, use adequate spray volumes, properly calibrated application equipment and a spray adjuvant if necessary. Failure to provide adequate coverage and retention of the product on leaves and fruit, if present, may result in loss of insect control or delay in onset of activity. Minimum spray volumes, unless otherwise specified on crop specific application sections, are 10.0 gallons per acre by ground. The product may be applied by chemigation (see Chemigation section) if allowed in the specific application section.


Do not apply with aerial application equipment.

Do not apply more than 0.50 pound active ingredient per acre, per year, regardless of formulation or method of application, unless specified within a crop-specific, Application Instructions section for a given crop.

Apply Widow Insecticide directly into the seed or root-zone of crop. Failure to place Widow Insecticide into root-zone may result in loss of control or delay in onset of activity. Apply Widow Insecticide with ground or chemigation equipment. Broadcast, foliar applications are only to be used for seedling flats or trays, or where product is intended to be washed from foliage to soil prior to drying on foliage.

Optimum activity of Widow Insecticide results from applications to the root-zone of plants to be protected. The earlier Widow Insecticide is available to a developing plant, the earlier the protection begins. Widow Insecticide is continuously taken into the roots over a long period of time and the systemic nature of Widow Insecticide allows movement from roots through the xylem tissue to all vegetative parts of the plant. This results in extended residual activity of Widow Insecticide, the control of insects and the prevention and/or reduction of virus transmission or symptom expression, and plant health benefits. The rate of Widow Insecticide applied affects the length of the plant protection period. Use the higher rate within the specified rate range when infestations occur later in crop development, or where pest pressure is continuous. Widow Insecticide will generally not control insects infesting flowers, blooms or fruit. Additional crop protection may be required for insects feeding in, or on these plant parts and for insects not listed in the crop-specific, pests controlled sections of the label. Additional, specific Widow Insecticide application instructions are also provided in the crop-specific sections of the label.

Suppression, or less than complete control of certain diseases and insect pests including reduced feeding, may also result from a Widow Insecticide application. Residual control of these pests/diseases may require supplemental control measures.

Widow Insecticide use on crops grown for production of true seed intended for private or commercial planting is not permitted unless it is allowed under State specific, supplemental labeling. As with any insecticide, care must be taken to minimize exposure of Widow Insecticide to honey bees and other pollinators. Additional information on Widow Insecticide uses for these crops and other questions, may be obtained from the Cooperative Extension Service, PCAs, consultants or local Loveland Products, Inc. representatives.

Pre-mix Widow Insecticide with water or other appropriate diluent prior to application. Keep Widow Insecticide and water suspension agitated to avoid settling.


DO NOT graze treated areas or use clippings from treated areas for feed or forage. Prevent runoff or puddling of irrigation water following application. DO NOT apply this product to soils which are water logged or saturated, which will not allow penetration into

the root zone of the plants. Keep children and pets off treated area until dry.

Limitations, Restrictions, and Exceptions



- Not for use on crops grown for seed unless allowed by state-specific supplemental labeling.

- Maximum amount of Widow applied in the planthouse: 0.1 fluid ounces (0.00156 lb a.i.)/1000 plants.

- Maximum number Widow applications in planthouse: 1


Apply specified dosage to seedlings in trays in the planthouse, targeting soil media (tray drench), not more than 7 days prior to transplanting, in one of the following manners:

1. Uniform, broadcast high-volume foliar spray, followed immediately by sufficient overhead irrigation to wash Widow from foliage into potting media without loss of gravitational liquid from the bottom of the tray. Failure to wash Widow from foliage may result in reduced pest control;

2. Injection into overhead irrigation system, using adequate volume to thoroughly saturate soil media without loss of gravitational solution from the bottom of the tray.

The application made in the planthouse will only provide short-term protection and is not intended as a substitution for a field application. An additional field application must be made within 2 weeks following transplanting to provide continuous protection.

Applications of higher rates or increased number of applications in planthouse may result in significant plant injury. Transplants should be handled carefully during setting to avoid dislodging treated potted media from roots.

Important Note: Not all varieties of fruiting vegetables have been tested for tolerance to Widow applied to seedling flats. It is therefore recommended to treat a small number of plants and confirm tolerance for 7 days prior to treating entire planthouse.

Use not permitted in CA unless otherwise directed by supplemental labeling.

Pre-Harvest Interval

21 days

Restricted Entry Interval

12 hours

Exception: If the product is soil-injected or soil-incorporated, the Worker Protection Standard, under certain circumstances, allows workers to enter the treated area if there will be no contact with anything that has been treated.
