What is CALIBUR and its advantages?

CALIBUR (Thiodiazole Copper 20% SC), is a broad-spectrum systemic fungicide with bactericidal activity, that has protective and therapeutic effect.

Advantages of CALIBUR:

· It combines thiazole groups with copper ions for dual-action pathogen control: thiazole groups have unique therapeutic effect against bacteria, and copper ions are very efficient on preventing fungi and bacteria.

· High safety: very low toxicity, it is safe for human, livestock, fish, can not only be applied in all growth stages of plants, but also be mixed with most pesticides, and PGR.

· No resistance issues: sustainable for repeated use

· Long-lasting efficacy: 10-14 days under normal dosage

· Highly effective to treat bacterial and some key fungal disease: bacterial (blight, leaf spot, wilt, rot etc..); fungal (powdery mildew, sclerotinia disease etc...)

· Can be applied on most crops: (cotton, soybean, rice, corn, cassava, fruit, vegetables etc.…)


How to use Calibur?
  • Foliar application: Dilute evenly with 500 times for general crops, apply by interval of 7-14 days

  • Root application: Dilute with 500-800 times, apply through Irrigation or flush the liquid to the plant’s root and by interval of 7-14 days.


How long can last Calibur efficacy?

It can last 12 days, so it should be applied twice for each course of treatment. 

Is CALIBUR more efficient against fungal or bacterial diseases?

Calibur is efficient for preventing fungal and bacterial disease. It is highly effective to treat bacterial diseases.

Can Calibur be mixed with another agrochemical?

Yes. It can be mixed with other agrochemical products except: 

  • those that contain Thiram AI

  • can’t be mixed with Difeconazole to control diseases of watermelon in greenhouses when the temperature is above 28oC, because Difeconazole can be phytotoxic on watermelon when the temperature exceeds 28oC

  • can’t be mixed with Azocyclotin to control diseases of citrus when the temperature is below 25oC, because Azocyclotin can be phytotoxic to citrus when the temperature is below 25oC


Can Calibur be used to control bacterial diseases on mononuclear fruits (peach, mango, apricot etc.)?

It can be used when the leave on shoots of the fruit tree grow to 3cm long to when the new branches grow to 10cm long. Stop applying in the fruit core hardening period, also when the temperature is above 25oC, do not apply Calibur to avoid phytotoxicity to the plants.

How to improve the control effect on diseases, pests, and weed under standard concentration?

Apply accurately on diseased parts of plants to enhance control effects.
