Thrips remain the number one pest of floriculture crops in California.
Many growers approach thrips management using regular prophylactic sprays
with the idea that there is a zero tolerance for thrips in the crop.
Working with roses, we embarked on developing an IPM program for thrips
which encompassed proper identification, statistically accurate sampling
plans, economic thresholds, biological control and reduced risk pesticides,
and cultural and physical controls. A successful program for managing
thrips on roses must also include compatible management plans for other key
pests -- twopspotted spider mites and rose powdery mildew. Strategies for
managing these other pests were included in an overall IPM program
delivered to rose growers in California.
