Tools for thrips control in roses
After establishing successful biological control of spider mite, thrips are often the next challenge in roses. Dutch growers are very enthusiastic about intensive application of small (10x25cm) Horiver-TR. blue sticky traps in combination with Lurem-TR. to catch thrips adults.
This measure is combined with frequent introductions of Amblyseius swirskii, sometimes Hypoaspis on substrate and/or soil, and corrective sprays with thiamethoxam or spinosad mixed with Attracker. Removing open flowers and buds is common practice. It is very important to bring this material rapidly out of the greenhouse and prevent thrips to escape and re-invade the crop.
