Numerous insect and mite pests in Florida affect production and economic returns in strawberry. Crop managers face enormous difficulties in managing these arthropods efficiently. Once the strawberry crop is in the field, there largely remain only three options for management, (1) a few cultural techniques such as removing ripe fruit from the field to reduce infestations of sap beetles, (2) a few biological techniques such as releasing Phytoseiulus persimilis for control of twospotted spider mite, and (3) insecticides and miticides.
There are numerous active ingredients available to strawberry crop managers in Florida. In many cases the selection and effective use of products among these is key to the efficient management of losses to arthropods. Table 1 presents the active ingredients available to strawberry crop managers in Florida, selected products available from each of the active ingredients, reentry and pre-harvest intervals that must be observed, and arthropods presented on product labels that may be important strawberry crop managers in Florida. Other products composed of the active ingredients may be available and other arthropods may be presented on product labels.
The product label communicates the lawful use of the insecticides and miticides and must be read, understood and followed. The label contains very important limitations that may not be presented in Table 1, such as restrictions on numbers of applications. When using a pesticide for the first time, it is important to apply the product first to a small portion of the crop and wait to observe possible detrimental effects, such as leaf distortion and plant stunting.
