TOPBUXUS Anti Rups® is a biological insecticide on the basis of Bacillus thuringiensis subsp. Kurstaki,
Dissolve 1 sachet (3 grams) of TOPBUXUS Anti Rups® in 4 litres of water, this mixture is sufficient for the treatment of 40m2 Boxwood.
Spray the plants completely with the mixture as soon as caterpillars are detected. In case of a large infestation or heavy rainfall, repeat the treatment. Treatment preferably only at an outside temperature above 15 degrees Celsius. Within a few hours after treatment, the caterpillars will stop their feeding. After 3-5 days they will die and fall off the plant.
The caterpillars eat the leaves that have been treated with TOPBUXUS Anti Rups® treated. Via enzymatic degradation in the stomach of the caterpillar, the protein crystals of Bacillus thuringiensis are broken down into toxins. These toxins bind to and penetrate receptors on the intestinal wall. The caterpillar is completely affected and eventually dies. Although it can take a few days for the caterpillar to die, the treatment with TOPBUXUS Anti Rups® is very efficient and effective. 1 to 2 hours after the intake of TOPBUXUS Anti Rups® the caterpillar stops eating, and so the damage done to the Boxwood is stopped as well. Please note: the caterpillars will only be affected after they ingest the treated leaves. Sometimes the caterpillars do not start feeding immediately, so they will not be affected but also cause no damage yet.
TOPBUXUS Anti Rups® is a biological insecticide that is not harmful to people or the environment. The natural enemies of the caterpillar, such as parasitic wasps, flies, bees and mites, are not affected by the product either.
Apply at a temperature of 15° C or above. If necessary, a second treatment could be carried out 2 weeks later in order to stop the caterpillar infestation completely. Can be used in combination with TOPBUXUS Health-Mix, both products can be mixed together to tackle both the Boxwood Caterpillar and the Box Blight in 1 treatment.
