Regalia® Biofungicide

Put invasive plants to good use! Regalia’s active ingredient is extract of giant knotweed, an aggressive plant invader in many countries around the world. Sprayed on your crops, it induces systemic resistance, stimulating biochemical pathways that strengthen the plant structure to fight pathogenic fungi. Reapply every 7–14 days to protect new growth.

May also be applied as a soil drench or through drip irrigation to improve root quality and protect against soil-borne pathogens. Labeled for a broad range of fungal diseases in most edible crops. Definitely worth a try to prevent late blight in your potatoes!

Various university trials have shown Regalia to be effective for downy and powdery mildew in cucurbits; bacterial spot, septoria leaf spot and powdery mildew in field tomatoes; mummy berry in blueberries; and powdery mildew and Botrytis bunch rot in grapes. Cannabis growers use it as a drench administered with liquid nutrients to prevent fungal problems, which is probably a good idea since you really don’t want to be smoking copper-based fungicides. Safe for bees. Please see pesticide label here. EPA reg. 84059-3.

These products come with detailed instructions on their labels. Contact us in case you don’t receive the attached booklet or if the label is illegible.

While we try to stay current with product specifications, product formulations are subject to change without notice.

Use our Sprayers to apply these products. We welcome your suggestions about successful low-impact pest-control methods or products.

Is that pesticide registered in your state?

Each state treats potentially dangerous items differently. Like alcohol and open-carry laws, pesticide registrations are different everywhere. We cannot ship a pesticide to a state where it is not registered.

Before buying or using any pest- or disease-control product, be sure it is registered for use in your state and, if you are a commercial grower, registered for commercial production.

Purdue University has a searchable database of information for most states. You can look up products by name, registration number or active ingredient. Contact information is provided for states that don’t participate in the website.

USDA NOP rule concerning disease and pest control
Caution certified-organic growers:

Before using any of these products for pest or disease control, you must have followed the National Organic Program rule 205.206(e). A product being labeled here as allowed is not sufficient to meet standards for organic certification.
