Apex-50 - Emamectin Benzoate 1.5% + Fipronil 3.5% SC - Crystal
Apex-50 Insecticide by Crystal Crop Protection
Emamectin benzoate 1.5% + fipronil 3.5% SC for thrips and fruit borer in chilli.
What it controls: Thrips and fruit borer in chilli.
When to use it: Follow the current Apex-50 pack for pest stage, crop stage and treatment timing.
What to include: The exact SC formulation, complete application directions and separate harvest and re-entry checks.
Why Choose This Product? Key Benefits
- 🌶️Chilli-focused use: The stated programme is for two important pest problems in chilli.
- 🔎Thrips control: Thrips are a named target, rather than an inferred use from another crop.
- 🐛Fruit-borer control: The same manufacturer recommendation includes fruit borer.
- 🥚Activity at hatching: Crystal describes activity against newly hatched larvae. This does not establish a separate egg-treatment programme.
- 🔀Two target sites: The mixture combines two insecticide groups that disrupt different parts of pest nerve signalling.

How It Works: Mode of Action
Apex-50 contains two active ingredients with different nerve-action target sites. The product is not interchangeable with a straight emamectin or fipronil formulation.
- Emamectin affects nerve and muscle signals: The Group 6 ingredient changes the activity of channels that regulate nerve signals, which can lead to paralysis.
- Fipronil affects another nerve pathway: The Group 2B ingredient blocks a different chloride-channel pathway, disrupting normal nerve activity.
- Susceptible pests lose normal function: Together these actions support control of the labelled thrips and fruit-borer targets. They do not guarantee control of unlisted pests or resistant populations.
Use suitable alternatives with different mode-of-action groups as part of crop-specific resistance management. A different brand name is not necessarily a different mode of action.

Dosage & Application Guide
Crystal publishes 200–250 ml/acre for chilli thrips and fruit borer. A separate CIBRC formulation reference is shown below for comparison; it is not permission to enlarge the brand rate or an additional treatment. Confirm the current pack’s full programme before use.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Chilli: manufacturer rate | 200–250 | See note* | See note* | See note* |
| Chilli: formulation reference | Approx. 202.3–303.5 500–750 ml/ha |
Approx. 202.3 500 L/ha |

The brand rate and the formulation reference remain separate. Do not combine them or use the higher generic maximum as the Apex-50 maximum. Acre conversions are approximate; original hectare quantities remain shown.
*Current-pack application route, crop and pest stage, water, harvest interval and re-entry directions must be confirmed. No per-litre rate is provided. The generic waiting-period entry mixes a three-day figure with a 48-hour re-entry reference, so it is not presented here as an interchangeable harvest rule.
How to Apply: Best Practices
- Identify the target: Check that the problem is chilli thrips or fruit borer. A leaf-curl symptom alone does not identify the pest or establish this treatment.
- Confirm timing and method: Use the current Apex-50 label for the application route, crop stage, pest stage, equipment and coverage. Do not infer these from the numerical references.
- Select the exact pack programme: Check the product quantity, matching water and mixing sequence together. Do not replace the brand range with the larger generic formulation range.
- Keep mixtures within the label: Do not add another pesticide, fertilizer or additive without permitted directions for that combination.
- Separate harvest and re-entry: The time before picking chilli and the time before people re-enter the treated area are different requirements. Obtain both from the current pack.
- Plan resistance management: Avoid relying repeatedly on Groups 6 and 2B. Follow crop-specific rotation guidance and the pack’s repeat-treatment limits.
Frequently Asked Questions
What pests is Apex-50 intended for in chilli?Crystal lists thrips and fruit borer. The description does not extend the product to every sucking or chewing pest.
Is Apex-50 the same as emamectin benzoate 5% SG?No. Apex-50 is the combination SC containing emamectin benzoate 1.5% and fipronil 3.5%. Do not substitute another formulation’s dose or directions.
Which dose is the manufacturer’s published rate?200–250 ml/acre for the listed chilli pests. The separate generic formulation reference is not an instruction to increase that rate; confirm the current pack before applying.
Can a 48-hour re-entry interval replace the time before picking chilli?No. Re-entry and harvest intervals serve different purposes. The mixed generic entry is not a complete harvest instruction, so verify both requirements on the current Apex-50 pack.
Does activity against newly hatched larvae mean I should spray on a fixed schedule?No. It describes product activity, not a fixed spraying calendar. Use the labelled timing, field assessment and repeat-treatment limits.
Safety & Disclaimer
