Benevia insecticide is an anthranilic diamide insecticide in the form of an oil-based suspension concentrate (oil dispersion), to be mixed with water and applied as a foliar spray. Benevia is particularly active on both sucking and chewing (Lepidopteran) insect pests and is specially formulated for maximum performance by foliar applications in vegetables.
Before application monitor insect populations to determine whether or not there is a need for the application of Benevia insecticide based on locally determined economic thresholds. More than one treatment of Benevia insecticide may be required to control a population of pests.
Benevia enters larvae primarily by ingestion, but also by contact. The product also shows ovicidal, ovi-larvicidal, and adulticide efficacy, depending upon the pest species. Exposure of the pest species typically results in rapid feeding cessation within a few hours of exposure, however, the time to death may take 3 to 6 days, depending upon the species.
Integrated Pest Management
Benevia insecticide has been specifically designed for use in Integrated Pest Management (IPM) schemes. Application of Benevia according to this label is expected to be safe to predatory mites, and spiders, but may have adverse effects on parasitoid wasps, ladybird beetles, lacewings and rove beetles in the treated field and parasitoid wasps in downwind areas reached by spray drift. While these beneficial arthropods cannot be relied upon to control pests, they are of potential value and can be monitored along with pests in pest management programs on these crops. According to the standards of Good Agricultural Practices and stewardship, Benevia should not be applied when honeybees are actively foraging.
Insecticide Resistance Warning
For insecticide resistance management Benevia insecticide is a Group 28 insecticide.
Some naturally occurring insect biotypes resistant to Benevia and other Group 28 insecticides may exist through normal genetic variability in any insect population. The resistant individuals can eventually
dominate the insect population if Benevia and other Group 28 insecticides are used repeatedly. The effectiveness of Benevia on resistant individuals could be significantly reduced.
Since the occurrence of resistant individuals is difficult to detect prior to use FMC accepts no liability for any losses that may result from the failure of Benevia to control resistant insects.
Benevia may be subject to specific resistance management strategies. To help prevent the development of resistance to Benevia observe the following instructions:
Use Benevia in accordance with the current Insecticide Resistance Management (IRM) strategy for your region.
Apply Benevia or other Group 28 insecticides using a “window” approach to avoid exposure of consecutive insect pest generations to the same mode of action. Multiple successive applications of Benevia or other Group 28 insecticides are acceptable if they are used to treat a single insect generation.
Following a “window” of Benevia or other Group 28 insecticides, rotate to a “window” of applications of effective insecticides with a different mode of action.
The total exposure period of all “Group 28-active windows” applied throughout the crop cycle (from seedling to harvest) should not exceed 50% of the crop cycle.
Incorporate IPM techniques into the overall pest management program.
Monitor insect populations for loss of field efficacy.
For further information contact your farm chemical supplier, consultant, local Department of Agriculture or Primary Industries, or local FMC Representative.

Fill spray tank to ¼ to ½ full of water. Measure the amount of Benevia required for the area to be sprayed. Add Benevia directly to the spray tank with the agitation engaged. Mix thoroughly to disperse the insecticide. Once dispersed, the material must be kept in suspension at all times by continuous agitation. Use mechanical or hydraulic means, DO NOT use air agitation, premix or slurry.
If spray solution is left standing, ensure thorough re-agitation of the spray mix until fully resuspended. DO NOT allow spray mix to sit overnight, as resuspension may be difficult.
Use an ethylated seed oil (such as Hasten) at 200 mL/100 L, up to a maximum of 1 L/ha.
DO NOT add a surfactant/wetting agent if:
mixing with another product which already contains a surfactant and/or the product label advises not to add a surfactant.
mixing with a liquid fertiliser
Acidification of the Spray Tank
If the pH of the spray tank after all products have been added and mixed is above pH 8, adjust to pH 8 or less using a registered acidifying agent. If the spray tank pH is 8 or less no adjustment of the spray tank pH is necessary. Spray tanks of pH 8 or less can be held for up to 8 hours before spraying. DO NOT store the spray mixture overnight in the spray tank.
Benevia insecticide is compatible with many commonly used fungicides, liquid fertilisers, herbicides, insecticides, and biological control products. However, since the formulations of products are always changing, it is advisable to test the physical compatibility of desired tank mixes and check for adverse effects like settling out or flocculation. To determine the physical compatibility, add the recommended proportions of the tank mix products to water, mix thoroughly and allow to stand for 20 minutes. If the combination remains mixed, or can be re-mixed readily, it is considered physically compatible. Avoid complex tank mixtures of several products or very concentrated spray mixtures.
The crop safety of all potential tank-mixes, including additives and other pesticides, on all crops has not been tested. Before applying any tank-mixture not specifically recommended on this label or other FMC supplemental labelling, the safety to the target crop must be confirmed. To test for crop safety, apply the combination to a small area of the target crop in accordance with the label instructions to ensure that a phytotoxic response will not occur.
DO NOT mix with copper based fungicides.
