What is it suitable for?
For aphids, whiteflies and young caterpillars on ornamentals up to 50 cm, excluding pear and ornamental conifers. Drench against fungus gnat larvae only during ornamental young-plant propagation in a greenhouse.
The essentials for mixing, treatment and harvesting.
For aphids, whiteflies and young caterpillars on ornamentals up to 50 cm, excluding pear and ornamental conifers. Drench against fungus gnat larvae only during ornamental young-plant propagation in a greenhouse.
Example for outdoor tomatoes up to 50 cm: mix 2 ml concentrate with 600 ml water for 10 m². Other plants and heights have their own rates.
Start at the first pests, at the appropriate development stage. For spray applications, wet both sides of the leaves without dripping. Treat in the evening, in calm conditions with no rain expected; avoid strong sun and temperatures above 25 °C.
According to the manufacturer: feeding stops within a few hours; death follows after a few days. Azadirachtin inhibits feeding and development. Existing feeding holes remain visible.
Example for outdoor tomatoes: 7–10 days apart, no more than 3 applications per crop or calendar year. Other crops have their own intervals and maxima.
Before harvest: 3 days for tomatoes, 4 for potatoes, 7 for spinach and 14 for fresh herbs except chives, for the listed uses. Use the prepared solution the same day.
Schematic examples for orientation. Images do not replace reliable pest identification.
Aphids often cluster on young growth and the undersides of leaves. Leaves may curl, but curling alone does not prove an aphid infestation.
Young caterpillars may scrape the leaf surface, leaving pale windows and fine silk. Before treatment, identify the caterpillar and match the crop to an authorised use.

The illustrations show a simplified sequence following an authorised spray application. They do not replace the application rate or instructions.
Following an authorised spray application, the active ingredient enters the leaf and is distributed partly systemically within it. Sucking or feeding pests take it up.
Feeding and further development are impaired. Pests die over time; the course depends on factors including pest species and life stage.
Pests may initially remain visible. Existing leaf damage is not repaired.
Schematic illustration, not a record of an actual treatment.
Azadirachtin is classified in IRAC group UN. The observable effects are described here without claiming a fully established molecular target.
Examples include young stages of aphids, whiteflies and caterpillars on ornamentals up to 50 cm; pear and ornamental conifers are excluded. On outdoor potatoes, the target is Colorado potato beetle larvae at stages L1–L3. Drenching against fungus gnats is authorised only during ornamental young-plant propagation in a greenhouse.
Example: for 10 m² of outdoor tomatoes up to 50 cm tall, mix 2 ml concentrate with 600 ml water. This is 0.2 ml product in 60 ml water per m². Taller plants and other crops have their own rates; this mixture is not a universal dose per litre.
Start when the first pests or symptoms appear, at the authorised pest stage. For spray applications, wet the leaves, including their undersides, without dripping. Preferably treat in the evening; outdoors, choose calm conditions with no rain expected. Do not apply in strong sunshine or above 25 °C.
After uptake through feeding or sucking, azadirachtin inhibits feeding and development. According to the manufacturer, feeding stops within a few hours and death follows after a few days. Progress depends on the pest, its stage and correct application. Monitor new damage and the infestation; existing feeding holes remain visible.
For the authorised ornamental spray uses: 7–10 days apart, no more than 4 treatments. For the listed vegetable and herb uses: 7–10 days, no more than 3. For potatoes: at least 7 days, no more than 2. Fungus gnats have a separate drench use with 7–14 days between treatments and no more than 4 treatments. All maxima also apply to the crop or calendar year.
After the last treatment, the respective authorised uses require 3 days before harvesting tomatoes, 4 for potatoes, 7 for spinach and related species, and 14 for fresh herbs except chives. The pre-harvest interval does not describe how quickly the product works. Prepare only the amount of solution needed and use it the same day.
The active ingredient is obtained from neem seed extract. After uptake by the pest, feeding and further development can be disrupted. Its effect develops in stages; immediately visible dead insects are therefore not the only measure of treatment success.
Choosing a measure starts with identifying the cause. Not every change in a leaf is caused by insects. Consider growing conditions, watering and beneficial organisms already present.
There is a non-professional spray use for ornamentals up to 50 cm in rooms, offices and on balconies, excluding pear and ornamental conifers. The pest and its life stage must match. The plant tolerance list in the actual instructions must also be checked; this is not blanket permission for every houseplant.
No. The documented drench use is restricted to ornamental young-plant propagation in a greenhouse. It specifies 15 ml per m² in 3 litres of water per m². This is not a general recommendation for mature houseplants or any growing medium.
There is no single dilution for every use. Plant, height, setting and method determine the permitted product rate and water volume per area. First choose the matching entry under “Application & rates”, then comply with both values.
Azadirachtin acts in stages after uptake through feeding or sucking. Development and feeding are disrupted; this differs from an immediate contact effect. Watch for new damage and changes in infestation rather than increasing the dose yourself.
This depends on the use: potatoes at most twice, at least seven days apart; the listed vegetable and herb uses at most three times, seven to ten days apart; ornamental spray uses at most four times, seven to ten days apart. The narrowly defined fungus-gnat drench use allows four treatments with seven to fourteen days between them. Crop and calendar-year limits must also be followed.
The interval differs: herbs other than chives 14 days, potatoes four days, spinach and related species seven days, and the listed fruiting vegetables and headed cabbages three days. These intervals apply only to the specified crops and authorised settings.
No. B4 applies only up to the highest authorised application rate or concentration. This bee classification does not imply general safety for other beneficial organisms. Follow the species-specific precautions and water protection requirements.
Do not spray or drench without a matching authorised use, increase rates yourself or store diluted spray solution. Avoid strong sunlight and temperatures above 25°C. Product residues and wash water must not enter drains or water bodies. Check the manufacturer’s plant tolerance list, especially for ornamentals.
Use plant protection products safely. Always read the label and product information before use.

The label, instructions and conditions for the selected use apply together. The official conditions below also include general protective requirements; exemptions for the individual home and allotment garden uses are reproduced in each application record. These official provisions are retained in German.
Keep children and pets away during treatment. Do not re-enter treated crops until the spray deposit has dried. If symptoms occur following contact, seek medical advice and have the product information available. Follow the current original label or safety data sheet for product-specific first-aid instructions.
Keep in the tightly closed, labelled original packaging in a lockable cupboard, inaccessible to children and pets and separate from food and animal feed. Follow the specific temperature and storage instructions on the current pack.
Prepare only the spray or drench solution needed and use it on the same day. Do not put leftovers, wash water or product residues into sinks, toilets, street drains or water bodies.
