OLEA can legally be used on tomatoes to control which of the following insects?

The correct answer is that applications onto tomatoes for any of the insects listed would be illegal because OLEA is not specifically registered for use on tomatoes for those pests according to the labels and regulations that govern pesticide application. In agricultural practices, the legality of using a pesticide on a specific crop hinges on the product's label, which outlines approved uses, target pests, and application methods.

If OLEA is not mentioned on the label for use on tomatoes, this means that it has not undergone the necessary evaluation for safety and efficacy on that crop. Thus, using it could pose risks to either the plants, the environment, or consumers. The careful selection and use of pesticides are essential in Integrated Pest Management (IPM) approaches to ensure compliance with regulatory standards while also protecting beneficial insects and the overall health of the ecosystem.
