Best Pesticides For Tomato Plants for Insects and Disease

#1 · Best Overall

1. Bonide Tomato Spray

• Form: item form
• Weight: 2 lb

Best for: Tomato growers seeking dual control.

Why it ranks #1: Specifically names tomatoes and vegetables, comes ready to use, and lists control for insects plus diseases including blight and powdery mildew.

Bonide Captain Jack’s Tomato & Vegetable Spray combines listed insect control with fungal-disease control in a ready-to-use 32-ounce spray. That pairing lets tomato growers address pests such as aphids and caterpillars while also targeting diseases including blight and powdery mildew, without mixing a concentrate first.

The ready-to-use format keeps preparation to spraying, while the broad pest list includes aphids, spider mites, caterpillars and thrips. Its disease coverage includes blight, powdery mildew, rust and leaf spot, so one product can address both kinds of garden problem. Bonide recommends applying early in the season as a protective spray before diseases are noticed; that timing is useful for growers planning preventive treatment rather than waiting for visible symptoms. Listed use also includes fruits, vegetables and ornamentals, indoors and outdoors.

Skip it if you need a concentrate for a large treatment area; BioAdvanced Vegetable & Garden Insect Spray lists coverage of 5,333 square feet of lawn.

Choose this for tomato and vegetable growers who want ready-to-use insect and fungal-disease coverage in one spray. Its preventive disease guidance matters: plan early-season application rather than relying only on treatment after symptoms appear.
