• Chemical pesticides: ask before you spray

  The source lists chemical sprays for fruit borers, leafhopper, aphids, mites, whiteflies, powdery mildew and nematodes. Many are hazardous, and some may be restricted. Vegetables are eaten fresh, so choose any product only with your local Agriculture Officer.

  Follow the instructions on the product label. Consult your local Agriculture Officer before use.
