BioWorks introduces Sandrine Copper Soap and Cintro Insecticidal Soap

Biological-based plant health solutions BioWorks announced the launch of Sandrine Copper Soap and Cintro Insecticidal Soap.

These two crop protection products are designed for effective, targeted control of key fungal, bacterial and insect pests within IPM programs. These solutions support commercial production in greenhouse, nursery, ornamental, cannabis and specialty crop systems. 

Sandrine Copper Soap is a liquid copper octanoate formulation that provides broad-spectrum activity against fungal and bacterial pathogens, including Corynespora, powdery mildew, Botrytis, bacterial leaf spots and downy mildew.

The dual mode of action combines:

• Preventative activity: The copper forms a protective barrier and inhibits spore germination.
• Curative activity: The octanoate penetrates infected tissue, disrupting cell membranes.

Sandrine Copper Soap delivers enhanced coverage with a lower metallic copper equivalent (MCE) of 1.8%, compared to 30 to 50% in conventional copper soap, reducing risk of phytotoxicity while maintaining efficacy. It is labeled for indoor use on crops including ornamental plants, tomatoes, cucumbers, melons, strawberries, roses and vegetables.

Sandrine Copper Soap has a 4-hour REI and 0-day PHI, compared to typical copper soaps requiring 24 to 48 hours.

Trial data:

In a trial recording bacterial spot on peaches, there was 55% reduction in disease incidence using Sandrine Copper Soap, compared to 30 to 40% with competitive products.

In a trial recording the fungus Alternaria solani on tomatoes, there was 95% control with Sandrine Copper Soap, compared to 85% with competitive products.

Key specifications:

Active ingredient: Copper octanoate

Formulation: Liquid

REI/PHI: 4-hour REI, 0-day PHI

Cintro Insecticidal Soap is a potassium soap of fatty acids providing contact-based control of soft-bodied insects, including aphids, whiteflies, spider mites, thrips, mealybugs and leafhoppers.

The mode of action eliminates pests by damaging cell membranes and stripping away the protective waxes that shield the insect.

Cintro Insecticidal Soap is labeled for indoor and outdoor use and is effective on bedding plants, trees and shrubs, citrus and stone fruit, nuts, herbs, vegetables and other specialty crops.

Cintro Insecticidal Soap has a 12-hour REI and 0-day PHI and is highly compatible with beneficials, making it well-suited for IPM integration.

Trial data:

In a trial recording the control of diamondback moth larvae there, was a 96% mortality rate when treated with Cintro Insecticidal Soap, compared to 10% with a horticultural oil treatment.

In a trial recording the control of two-spotted spider mites, there was 92% control rate, compared to 82% with a competitive insecticidal soap.

Key specifications:

Active ingredient: Potassium salts of fatty acids

Formulation: Liquid

REI/PHI: 12-hour REI, 0-day PHI
