Koppert is introducing a species of ladybird – Rhyzobius lophanthae – that will help growers control various types of armored scales in their crops. The species is proving to be effective in a number of outdoor crops, including citrus, grapes, blackberries, kiwi, and mango.
Armored scales suck cell sap in fruit trees and berries that, eventually result in defoliation and the dying back of twigs or larger branches. To prevent this, Rhyzobug can be applied both in greenhouses and in outdoor crops to control a wide range of harmful scale insects.
Product Manager Jenette Douma: "Our colleagues at Koppert Spain have been instrumental in making this product effective for outdoor cultivation. We have increased the volume of Rhyzobug from 250 to 500 ladybirds and changed the packaging from a plastic bottle to a more sustainable cardboard tube, which is more suitable for agriculture."
"Rhyzobug significantly reduces the need for pesticide applications. On top of that, it simplifies compliance with the pesticide blacklist within the value chain. Plus, by opting for this method, growers are contributing to the production of healthier end products," the Koppert team explains.
"Rhyzobug is also eco-friendly as it promotes biodiversity and supports environmental preservation. It effectively controls various species of armored scales. The ease of application makes it accessible to growers of all levels, ensuring hassle-free implementation. Furthermore, Rhyzobug seamlessly integrates with other natural pest control methods, such as introducing Aphytis melinus. Notably, both adults and larvae of Rhyzobug actively prey on armored scale insects, providing a dual approach to pest control that's both efficient and sustainable."
Rhyzobug has a wide host range and predates on oleander scale, rose scale and Californian red scale, amongst others. "It’s really easy to apply," Jenette Douma assures. "You need to start the introduction as soon as the first armored scales are detected. You apply it in the evening and tap the beetles directly onto the plants based on 500-3000/ha (for outdoor cultivation) in several applications depending on the degree of infestation."
As with all live insect transportation, special care needs to be taken for the ladybirds to be fit to do their work in the crop on arrival. "Our furthest destination at the moment is South Africa, and our road and flight transportation trials have proved to be successful," Jenette explains. Rhyzobug will initially be available in Italy, France, Spain, and South Africa.
