Spinosad, a new tool for insect control in vegetables cultivated in greenhouses.
Spinosad is a biological insecticide derived as a fermentation product from the soil actinomycete Saccharopolyspora spinosa. The compound was tested for its possible use in northwestern Europe in vegetables cultivated in greenhouses. Spinosad is an insect control agent that has activity against a wide range of insect pests including caterpillars, leafminers and thrips. Because of its selectivity on a large number of beneficials used in greenhouses, spinosad is an interesting tool for insect control. A SC formulated product, containing 480 g a.i. litre-1, was tested in 1998, 1999 and 2000 in a range of trials at the research stations of Naaldwijk/Netherlands, and Gembloux/Belgium. This paper reviews and discusses the efficacy results on Trialeurodes vaporarium, Frankliniella occidentalis, Chrysodeixis Chalcites, Liriomyza Bryoniae. According the target insect rates from 4.8 till 36 g a.i./hl were tested. Consistent performance was recorded on F. occidentalis at rates of 9.6 g a.i./hl or above. Interesting efficacy results were recorded on the other above-mentioned insects.
