General Information


For soil applications of Imidacloprid 4F, direct product into the seed or root zone of crop. Failure to place Imidacloprid 4F into root zone may result in loss of control or delay in onset of activity. Apply Imidacloprid 4F with ground or chemigation application equipment.

Do not apply Imidacloprid 4F in enclosed structures such as planthouses or greenhouses.

Apply foliar applications of Imidacloprid 4F as a directed or a broadcast foliar spray. Thorough coverage of foliage is necessary without runoff for optimum insecticidal efficacy. Use adequate spray volumes, properly calibrated application equipment, and spray adjuvant if necessary to obtain thorough coverage. Failure to provide adequate coverage and retention of Imidacloprid 4F on leaves may result in loss of insect control or delay in onset of activity. Apply Imidacloprid 4F with properly calibrated ground or aerial application equipment. Minimum spray volumes, unless otherwise specified on crop-specific application section, are 10 gallons per acre by ground and 5 gallons per acre by air. Imidacloprid 4F may also be applied by overhead chemigation (see additional information in CHEMIGATION section of the label) if allowed in crop-specific application section.

When applied as a soil application, optimum activity of Imidacloprid 4F results from applications to the root zone of plants to be protected. The earlier Imidacloprid 4F is available to a developing plant, the earlier the protection begins. Imidacloprid 4F is continuously taken into the roots over a long period of time and the systemic nature of Imidacloprid 4F allows movement from roots through the xylem tissue to all vegetative parts of the plant. This results in extended residual activity of Imidacloprid 4F, the control of insects, and the prevention and/or reduction of virus transmission or symptom expression, and plant health benefits. The rate of Imidacloprid 4F applied affects the length of the plant protection period. Use higher rates when infestations occur later in crop development or where pest pressure is continuous. Imidacloprid 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 the label. Additionally, specific Imidacloprid 4F application instructions are also provided in the crop-specific sections of the label.

Suppression or less than complete control of certain insect pests that may carry diseases including reduced feeding may also result from an Imidacloprid 4F application. Complete control of these pests may require supplemental control measures.

Generally, Imidacloprid 4F is not used on crops grown for production of true seed intended for private or commercial planting but may be allowed under state-specific, supplemental labeling. As with any insecticide, minimize exposure of Imidacloprid 4F to honey bees and other pollinators. Do not use Imidacloprid 4F on crops requiring bee pollination during bloom and a minimum of 10 days prior to bloom. Additional information on Imidacloprid 4F uses for these crops and other questions may be obtained from the Cooperative Extension Service, PCAs, consultants, or local Makhteshim Agan of North America, Inc. representatives.

Apply only to plants grown in field-type soils, potting media, or mixtures thereof. Do not apply to plants grown in nonsoil medias such as perlite, vermiculite, rock wool, or other soil-less media, or plants growing hydroponically.

Pre-mix Imidacloprid 4F with water or other appropriate diluent prior to application. Keep Imidacloprid 4F and water suspension agitated to avoid settling.

Do not apply more than 0.5 lb. 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.

Limitations, Restrictions, and Exceptions



- Minimum interval between applications: 7 days

- Maximum Imidacloprid 4F allowed per crop season when making foliar applications: 10 fluid ounces per acre (0.31 lb. AI per acre)

- Regardless of formulation or method of application, apply no more than 0.5 lb. active ingredient per acre per season, including seed treatment, soil, and foliar uses.

- Do not graze treated fields after any application of Imidacloprid 4F.

- Apply Imidacloprid 4F through properly calibrated ground, aerial, or chemigation application equipment.

- Do not apply more than a total of 6 applications of the active ingredient per season.

Applications: Apply specified rate per acre as a broadcast or directed foliar spray to an infested area as pest populations begin to build. Thorough uniform coverage is necessary to achieve optimum control. Use a spray adjuvant to improve coverage. Imidacloprid 4F may not knock down established and heavy insect populations. Two applications may be required to achieve control. Scout fields and re-treat if needed. Tank mix Imidacloprid 4F with other insecticides for knockdown of pests or for improved control of other pests.
