The population growth of aphids can be sometimes very fast, leading to great damage in several crops. It is therefore very important to locate the aphids and take necessary measures. Biobest offers a whole series of parasitoids and predators against aphids.
Voracious on several crops
Caterpillar damage usually occurs in late summer and early autumn, but recently some caterpillars have been causing problems throughout the growing season. There are several biological control methods of caterpillar control.
Steinernema-System (insect nematodes Steinernema feltiae packed per 50 million or 200 million)
A population of spider mites can grow very rapidly, especially under dry and warm conditions. Fast action is recommended to keep the spider mite densities as low as possible.
Adult thrips are small, elongated insects with typical fringed wings. They measure about 1 mm, and have a greyish or yellow to brown colour. The two most common harmful species are the onion thrips (Thrips tabaci) and the western flower thrips (Frankliniella occidentalis).
Amblyseius-System (A.B.S) (predatory mite - Amblyseius cucumeris in sachets)
Amblyseius-System (predatory mite - Amblyseius cucumeris)
Adult weevils feed at night producing telltale notches around the edges of leaves and flowers. The damage is most severe when caused by the voracious larvae, feeding on roots. Heterorhabditis-System provides rapid and effective control of vine weevil.
