Resistance Management
Some insects are known to develop resistance to insecticides after repeated use: As with any insecticide, the use of this product should conform to resistance management strategies established for the use area. Couraze 4F contains a Group 4A insecticide. Insect biotypes with acquired or inherent tolerance to Group 4A insecticides may eventually dominate the insect population if Group 4A insecticides are used repeatedly as the predominant method of control for targeted species. This may eventually result in partial or total loss of control of those species by Couraze 4F and to other Group 4A insecticides. The active ingredient in Couraze 4F is a member of the neonicotinoid chemical class. Insect pests resistant to other chemical classes have not shown cross-resistance to Couraze 4F. 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 Couraze 4F be made; 2) foliar applications of products from the same class not be made following a long residual, soil application of Couraze 4F, or other neonicotinoid products.
If a soil application of Couraze 4F has not been made during a crop season and foliar applications are to be made, avoid using a block of more than three consecutive applications of Couraze 4F and/or other Group 4A products having the same or similar mode of action. Following a neonicotinoid block of treatments, Cheminova strongly encourages the rotation to a block of applications with effective products with a different mode of action before using additional applications of neonicotinoid products. Using a block rotation or windowed approach, along with other IPM practices, is considered an effective use strategy for preventing or delaying an insect's ability to develop resistance to this class of chemistry. Do not use foliar applications of Couraze 4F or other Group 4A products from neonicotinoid chemical class to be used on crops previously treated with a long-residual, soil-applied products from the neonicotinoid chemical class.

APPLICATION DIRECTIONS
For soil applications of Couraze 4F, direct product into the seed or root zone of crop. Failure to place Couraze 4F into root zone may result in loss of control or delay in onset of activity. Couraze 4F may be applied with ground or chemigation application equipment.
Do not apply Couraze 4F in enclosed structures such as planthouses or greenhouses except as specified in the TOBACCO, CUCURBIT VEGETABLES, FRUITING VEGETABLES and GREENHOUSE VEGETABLES, (Mature plants in production greenhouses): Cucumber, Tomato only sections of this label. Apply foliar applications of Couraze 4F as a directed or broadcast foliar spray. Thorough coverage of foliage is necessary without runoff for optimum insecticidal efficacy. Use adequate spray volumes, property calibrated application equipment, and spray adjuvant if necessary to obtain thorough coverage. Failure to provide adequate coverage and retention of Couraze 4F on leaves and fruit may result in loss of insect control or delay in onset of activity. Couraze 4F may be applied with properly calibrated ground or aerial application equipment. Minimum spray volumes unless otherwise specified on crop specific application sections are 10 gallons per acre' by ground and 5 gallons per acre by air. Couraze 4F may also be applied by overhead chemigation (see additional information in "Chemigation" section of this label below) if allowed in crop specific application section.
When applied as a soil application, optimum activity of Couraze 4F results from applications to the rootzone of plants to be protected. The earlier Couraze 4F is available to a developing plant, the earlier the protection begins. Couraze 4F is continuously taken into the roots over a long period of time and the systemic nature of Couraze 4F allows movement from roots through the xylem tissue to all vegetative parts of the plant. This results in extended residual activity of Couraze 4F, the control of insects, and the prevention and/or reduction of virus transmission or symptom expression, and plant health benefits. The rate of Couraze 4F applied affects the length of the plant protection period. Higher rates within the specified rate range can be used when infestations occur later in crop development or where pest pressure is continuous. Couraze 4F 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 this label. Additionally, specific application information for Couraze 4F are also provided in the crop-specific sections of this label. Suppression or less than complete control of certain diseases and insect pests including reduced feeding may also result from application of Couraze 4F. Complete control of these pests/diseases may require supplemental control measures.
Use of Couraze 4F on crops grown for production of true seed intended for private or commercial planting is not permitted unless allowed under state specific, supplemental labeling. Additional information on uses of Couraze 4F for these crops and other questions may be obtained from the Cooperative Extension Service, PCAs, consultants, or local Cheminova, Inc. representatives. Application should be made only to plants grown in field-type soils, potting media, or mixtures thereof. Do not apply to plants grown in non-soil medias such as perlite, vermiculite, rock wool, or other soil-less media, or plants growing hydroponically. Couraze 4F should be pre-mixed with water or other appropriate diluents prior to application. Keep Couraze 4F and water suspension agitated to avoid settling. Do not apply more than 0.5 Ib. active ingredient per acre per crop season regardless of formulation or method of application, unless specified within a crop specific, application section for a given crop.
