Various plants are susceptible to Thrips. These are very small sucking insects that often infest stressed plants. In early summer, they attach themselves to the underside of susceptible plants and feed by sucking out the sap. This feeding cause further stress and can lead to discolouration of the plant’s leaves. In the case of severe infestations, the plant can lose all of its leaves and will not survive for very long. All susceptible plants need to be monitored beginning in early spring. Weather plays a big role in their population size, hot and dry weather helps their growth and spread to new plants.
We recommend three applications of Thrip control over spring and summer to ensure that their numbers are reduced to an acceptable level.
