Abstract

Management of the chrysanthemum miner in export crops in eastern Antioquia.

Abstract

In the light of studies in Colombia for the purpose of developing a programme for the management of Liriomyza sativae Blanch. on cultivated chrysanthemums, especially those grown for export, the authors make certain recommendations. These include the use of pyrethroids (especially permethrin (Ambush) and deltamethrin (Decis) as 0.15% sprays) to control the adults; treatment with 0.15% permethrin or cypermethrin (Ripcord) if both larvae and adults are present; the restriction of chemical treatments against the larvae to the periods when these are still in the early instars; the judicious rotation of the types of chemical compounds applied and the periodic inclusion of non-pyrethroid compounds (some suitable compounds being listed); and careful monitoring of the populations in order to avoid unnecessary treatments.
