David Grays Tomato Dust 3-in-1 500g – Insecticide, Fungicide and Miticide Dust for Tomato Plants

David Grays Tomato Dust 3-in-1 for Home Garden Tomatoes

David Grays Tomato Dust 3-in-1 is a ready-to-use tomato dust that works as an insecticide, fungicide and miticide in one 500g shaker pack. It controls caterpillars, mites and fungal diseases on tomatoes in the home garden, so you can protect your crop from its main threats without mixing separate sprays. It has a short 3 day withholding period, making it practical for home vegetable gardeners picking tomatoes through the season.

Three Actives in One Pesticide for Tomatoes

As a combined pesticide for tomatoes, the dust contains three active constituents, each with a different job:

• Carbaryl (19g/kg): an insecticide for tomato plants that controls chewing pests such as tomato grub, budworm and loopers
• Copper (40g/kg): a protectant tomato fungicide for leaf diseases such as blight and leaf spot
• Powdered sulphur (300g/kg): acts as a miticide against tomato mite and other mites, and helps control powdery mildew

Combining insect, mite and disease control means one product covers the most common tomato problems at once.

What Pests and Diseases Does It Control?

David Grays Tomato Dust 3-in-1 is used on tomatoes to control:

• Tomato grub (Heliothis caterpillar), native budworm and loopers
• Potato moth (tomato leaf miner)
• Tomato mite and other mites
• Early blight (target spot), late blight and septoria leaf spot
• Powdery mildew

Always check the pack for the full list of registered pests and diseases.

How to Dust Tomato Plants

• Start dusting seedlings about 7 days after transplanting
• Repeat every 7 to 10 days, and more often in rainy weather
• Apply after watering, puffing an even, thin film over the upper and lower leaf surfaces, stems and buds
• Dust when the air is still, ideally early morning or evening
• Avoid dusting when temperatures are above 30°C or when plants are moisture-stressed, as sulphur can scorch leaves in heat
• Avoid heavy application on young seedlings
• Do not pick tomatoes for 3 days after dusting

Frequently Asked Questions

What are the active ingredients in David Grays Tomato Dust 3-in-1?

David Grays Tomato Dust 3-in-1 contains 19g/kg carbaryl as the insecticide, 40g/kg copper as the fungicide and 300g/kg powdered sulphur as the miticide. Check the label on your pack, as older packs used a different formulation.

What does David Grays Tomato Dust 3-in-1 control?

It controls tomato grub (Heliothis caterpillar), budworm, loopers, potato moth (tomato leaf miner), tomato mite and other mites, plus diseases such as early blight, late blight, septoria leaf spot and powdery mildew on tomatoes.

Is tomato dust safe?

It is safe to use on home garden tomatoes when you follow the label, including the 3 day withholding period. Carbaryl is harmful to bees, so avoid dusting flowers while bees are foraging, wear gloves, avoid breathing the dust and wash produce before eating.

How to apply tomato dust?

Dust seedlings about 7 days after transplanting and repeat every 7 to 10 days. Apply an even, thin film to both sides of the leaves after watering, in still air, and avoid temperatures above 30°C.

What is the best natural fungicide for tomato plants?

Copper and sulphur are traditional, naturally derived fungicides widely used on tomatoes for blight, leaf spot and powdery mildew. This 3-in-1 dust contains both, but it also includes carbaryl, a synthetic insecticide, so it is not a fully natural product.

Can I use it on other plants?

It is formulated and registered for tomatoes in the home garden. Check the label for any other registered uses before applying elsewhere.
