RIMON Insecticide is a broad-spectrum larvicide and ovicide with long residual control that’s ideal for your integrated pest management program. Rather than attacking fully grown insects like most insecticides, the active ingredient in RIMON goes after eggs, larvae and nymphs while remaining easy on beneficials.
RIMON® provides excellent control of key pests in apples, stone fruit, berry crops, potatoes and many vegetable crops. It’s particularly effective on codling moth and Oriental fruit moth in apples, and on Colorado potato beetle and European corn borer in potatoes. RIMON, an insect growth regulator, disrupts cuticle formation and deposition, a unique mode of action that makes it an excellent resistance management tool.

Application rates and timing - Apples
Target Pests | Application Rate | Application Instructions |
Codling moth |
0.93-1.4 L product/1000 L Do not exceed 3500 L water/ha applied as a dilute spray. |
Application timing is based on biofix, which is based on the pest life cycle. Biofix is defined as the date of first sustained adult catch in pheromone traps. For the determination of degree days (DD) for codling moth, a lower and upper threshold of 10 and 31° C is used. For each codling moth generation: The 1st application should be made at 100 DD (161 DD for Western Canada) following biofix. Make additional applications at 10- to 14-day intervals, as required by monitoring. For the second generation, the first application is generally made 500 to 600 DD following the 1st generation biofix. To calculate degree days (DD) accumulation for codling moth, use a lower and upper threshold of 10 and 31° C and a base temperature of 10° C. Alternatively, refer to development information provided by local packinghouses or weather monitoring networks. In the absence of degree day development model, apply RIMON 10 EC about 7 to 10 days after biofix, weather permitting. RIMON 10 EC must be applied prior to egg deposition or shortly thereafter to prevent codling moth damage to fruit. RIMON 10 EC must be applied before larvae penetrate into the fruit. RIMON 10 EC will provide 10 to 14 days of fruit protection depending on the concentration and rate of fruit expansion. Increase the rate and decrease the application interval for heavy infestation or continuous moth flight and egg oviposition. DO NOT apply more than 4 applications per crop per season. DO NOT apply more than 10.97 L product/ha/crop/season. DO NOT apply within 14 days of harvest. |
Oriental fruit moth |
0.93-1.4 L product/1000 L Do not exceed 3500 L water/ha applied as a dilute spray. |
Begin applications before egg hatch of each generation to prevent larval penetration of the twigs and fruit. RIMON 10 EC will provide 10 to 14 days of protection depending on the concentration and rate of plant growth once applied. For situations of heavy infestations and continuous moth flight and egg oviposition, and where it is difficult to obtain thorough coverage, use the highest concentration and maintain coverage with reapplications at 10- to 14-day intervals, as required by monitoring. RIMON 10 EC must be applied before larvae penetrate into the fruit or twigs. DO NOT apply more than 4 applications per crop per season. DO NOT apply more than 10.97 L product/ha/crop/season. DO NOT apply within 14 days of harvest. |
Application rates and timing - Potatoes
Target Pests | Application Rate | Application Instructions |
Colorado Potato Beetle, European Corn Borer |
410-820 mL product/ha (44-88 g a.i./ha) |
DO NOT apply more than 2 applications per crop per season. DO NOT apply more than 1640 mL product/ha/crop/season (177 g a.i./ha/crop/season). DO NOT apply within 14 days of harvest. Colorado Potato Beetle: Application should be made when the majority of the population is at egg hatch to the second instar. Use higher application rates and spray volumes for higher pest pressure, when larvae are large or foliage canopy is tall or dense. Reapplication on a 10- to 14-day interval will be required to protect new growth or monitoring indicates that it is necessary. European Corn Borer: The first application should be made just prior to egg hatch. Scout for European corn borer to monitor egg-laying and egg hatch to determine application timing. Use higher application rates and spray volumes for higher pest pressure. Reapplication on a 10- to 14-day interval will be required to protect new growth or monitoring indicates that it is necessary. |
Application rates and timing - Stone fruit
Target Pests | Application Rate Litres/ha | Application Instructions Do not use RIMON 10 EC in alternate row middle application patterns since this method will result in off-timing application and poor performance. Apply in 1000 to 3000 Litres of water per hectare. |
Oriental Fruit Moth |
1.35-3.35 (145-363 g ai) |
Begin applications before egg hatch of each generation to prevent larval penetration of the fruit. RIMON 10 EC will provide 10 to 14 days of protection depending on the application rate and speed of plant growth once applied. For situations of heavy infestations and continuous moth flight and egg oviposition, and where it is difficult to obtain thorough coverage, use the highest labeled rate and maintain coverage with timely reapplications at 10- to 14-day intervals, as required by monitoring. RIMON 10 EC must be applied before the larvae penetrate into the fruit or twigs. RIMON 10 EC may be alternated with other registered insecticides targeted against the same pest as long as the application interval does not exceed the period of effectiveness of the alternate product. Do not apply more than 3 applications per crop per season. Do not apply more than 10.05 litres per hectare per season. Do not apply within 14 days of harvest. |
Peach Twig Borer |
1.35-3.35 (145-363 g ai) |
Dormant/Delayed dormant: Apply RIMON 10 EC with 38 to 56 litres per hectare of narrow range oil. Always use the higher rates if the orchard has a history of heavy populations. Bloom: Monitor for peach twig borer larvae and its damage during bloom when shoots are emerging, to determine if the pest is active. When emerging shoots are about 1 inch long, look for wilted leaf shoots and feeding at the base of flowers. If larvae or their damage are observed at this time, make application in sufficient spray volume for thorough coverage. In-Season: Monitor orchard from bloom onward for shoot strikes at the end of each generation. Shoot strikes first appear when the degree-day accumulation from moths in traps approaches 220 DD10° C but more will be evident around 385-440 DD10° C. If larvae or their damage are observed at this time, make application in sufficient spray volume for thorough coverage. Do not apply within 14 days of harvest. |
Oblique banded leafroller |
1.35-3.35 (145-363 g ai) |
Application timing is based on Biofix for the pest (if information is unavailable, contact your university or extension entomologist for targeting application at the initiation of egg hatch). The pest Biofix is based on the pest life cycle. Biofix is defined as the date of first sustained adult catch in pheromone traps – typically five moths in three traps in a seven-day period. Apply the RIMON 10 EC treatments at the following timings: First Generation: Second Generation: For all generations, best protection is achieved when applications are initiated at the beginning of oviposition. RIMON 10 EC will provide 7 to 14 days of protection depending on the application rate and rate of fruit expansion. Increase the rate and decrease the application interval for heavy infestations or continuous moth flight and egg oviposition. Do not apply more than 3 applications per season. Do not apply more than 10.05 litres per hectare per season. Do not apply within 14 days of harvest. |

835 Apply in sufficient volume to ensure thorough coverage. Recommended water volumes are 450-1400 Litres of water per hectare. |
First application should be made when insect populations reach locally determined economic thresholds. Reapplication on a 10- to 14-day interval may be required.

Application should be made when the majority of the population is at the egg hatch to second instar. Use higher rates and higher spray volumes when larvae are large or foliage canopy is tall or dense. For the most effective control, field should be scouted and sprays applied in a timely manner. Reapplication on a 10- to 14-day interval will be required to protect new growth or monitoring indicates that it is necessary. Do not apply more than 3 applications per crop per season. Do not apply within 8 days of harvest. Do not apply more than 6.0 Litres of product per hectare per season. |
