Product description
CRS Sachets
The controlled release sachet is a key treatment for Western Flower Thrip control in many crops. The formulation has a special ingredient from natural sources, which increases the number of predatory Amblyseius cucumeris mites that are released onto the crop each day. Mites are continuously released over a period of 6 weeks or more. The success of the Controlled Release System CRS sachet is that the predator is not reliant on food being available on the plant as it is a stand-alone breeding colony.
Predatory Mite
- More than 6 weeks of Thrips control
- Continuous releases of more than 400 mites per sachet per week
- Improved breeding system to give even release numbers over several weeks
- Unique formulation with the special Bioline ingredient
- Sachet with emergence hole
Gemini sachets
A unique patented twin sachet design for controlled release sachets, has been developed by Syngenta Bioline as a key treatment for Western Flower Thrips in ornamental crops. Suitable for hanging on crop wires or on the plant, this innovative product tolerates overhead watering, and ensures that Amblyseius cucumeris mites are released continuously in environments where normal sachets would not perform well. The breeding system in the Gemini sachets means that mites are released over a long period of around six weeks and the predators are not reliant on food being present on the crop for establishment.
Amblyseius cucumeris predatory mites are key components in the control of Thrips in integrated programmes. The unique design of these sachets, together with the materials used and careful formulation ensures maximum emergence of predatory mites even under stress conditions. The Gemini sachet design is quicker to place in the crop and can save labour hours.
Predatory Mite
- Gemini sachets with two predator breeding compartments
- Water runs off outer surface Emergence hole stays dry on inner surface Sachet contents protected! No hook to get wet so sachets remain on plants
- Continuous emergence even under irrigation
General Information
CRS Sachets
Amblyseius cucumeris predatory mites are key components in the control of thrips larvae in integrated programs. The predators emerge constantly onto the plant and hunt for thrips larvae. The humidity of the carrier, the type of paper used, the prey/predator balance in the carrier and the purity of the product are all important factors for successful use of this predator. Our formulation is ideal for drip-irrigated crops and releases more mites per day than ever before.

Lift each sachet from the box, pinch the join so that the printed face is outwards, and drop the sachet over the crop wire or leaf stalk. Do not hang adjacent to heating pipes.
Duration of activity is 6 weeks.
Use at 1 sachet per m² or per linear metre of crop row.

Amblyline cu Flo is a special formulation of Amblyseius cucumeris predators in vermiculite. This predatory mite is used in many crops as a key treatment for Western Flower Thrips. Amblyline flo is available as a Shaker Tube System or as a 5 litre bulk bag and may be used with motorized knapsack blowers. This new formulation is the result of a new improved breeding system resulting in a bran free product. Bran free means it is better to use on crops where the use of bran may lead to increased incidence of disease, particularly in ornamentals.
Predatory mite
- Completely new breeding system
- 100% Vermiculite carrier
- 100% Bran free
- Clean product, smooth-flowing
- Less Tyrophagous prey mites
General information
Amblyseius cucumeris feeds only on the smallest Thrips larvae but won’t attack larger larvae or adults. The predators disperse quickly over the crop hunting for Thrips larvae. It is also a recognized treatment for Tarsonemid mites in strawberry crops. Do not use at temperatures that remain below 10°C for long periods, or in very dry areas. For heavy populations or where there is the risk of virus transmission by thrips, use a clean up spray with short-lived surface residues, e.g. VERTIMEC,®, DYMAMEC® (crop registration restrictions apply) before releasing Amblyseius cucumeris. Follow up with Orius sp or use with Hypoaspis soil treatments. Consult your Syngenta Bioline representative for advice.
