Advantages of CALIBUR® (Thiodiazole copper 20%SC)

Special mode of action of CALIBUR® (Thiodiazole copper 20%SC)

The chemical structure of CALIBUR® is ring-shaped, with the characteristics of high stability and efficacy, it is easier to enter the tissues of crops (systemic conduction). Under the action of enzymes in the crops, the ring-shaped structure breaks down to form copper ions and thiazole groups.

• Thiazole group: Acting as a powerful therapeutic agent within plants, targeting bacterial cell walls to cause cellular thinning and breaking apart

• Copper ion: Providing fungicidal and bactericidal action

Together, these components deliver enhanced efficacy and a broader spectrum of targets.

Systemic, long-lasting protection and convenient to use

CALIBUR® (Thiodiazole copper 20%SC) has strong systemic properties, enabling multi-directional movement through plant epidermal cells, offering complete protection for crops from leaves to roots.

CALIBUR® (Thiodiazole copper 20%SC) can be mixed with most pesticides and fertilizers and applied through spraying, root dipping, flushing, smearing, drop irrigation and drone application.

Broad-spectrum and eco-friendly fungicide

CALIBUR® (Thiodiazole copper 20%SC) is widely used to control more than 60 kinds of bacterial and fungal diseases in China. The main targets are as follows.

Safe for copper-sensitive crops

CALIBUR® has been extensively applied to copper-sensitive crops. As copper ions might harm peach trees, growers are worry about applying copper-ion-based products to such crops.

Thiodiazole copper has emerged as an alternative pesticide. CALIBUR® (Thiodiazole copper 20%SC) is approved to control peach bacterial shot hole in China, demonstrating its efficacy and safety. CALIBUR® (Thiodiazole copper 20%SC), as a highly effective and safe fungicide, has excellent prospects regarding its application on peach trees and other copper-sensitive crops. Its unique chemical structure and mode of action ensure both efficacy and being free from phytotoxicity, obtaining trust and reputation from peach growers.

In addition, orchids have been affected by soft rot, stem rot, root rot, and other bacterial pathogens for a long time, resulting in flowering failure. CALIBUR® (Thiodiazole copper 20%SC) is approved to control orchid soft rot. Its excellent efficacy has won the trust of orchid growers and has become a popular and dedicated fungicide for flowers.

Safe for ecological farming systems

Fish-rice symbiosis and shrimp-rice symbiosis are unique agroecological systems in China. By raising fish and shrimp in rice paddy, fish and shrimp can improve the paddy environment and reduce insect, pests and weeds. Meanwhile, the excrement of fish and shrimp acts as a natural fertilizer to promote rice growth, achieving a win-win situation for ecology and economic benefits.

CALIBUR® (Thiodiazole copper 20%SC) is safe for the environment and crops, so it has been applied to these agroecological systems in China. Its proven performance after applications demonstrates its value in increasing economic benefits for the users.
