Brazil is one of the world’s largest citrus producing countries and São Paulo is the Brazilian largest citrus producing state. The total citrus plants in the 2018/2019 crop season was estimated in 175.26 million, including producing and growing ones, with an estimated production of 284.88 million of 40.8-kilo boxes.

Citrus industry is important for the Brazilian economy because it generates millions of jobs; however, the sector have facing phytosanitary problems over the years, especially diseases, that have caused negative impacts on citrus fruit production and marketing. Citrus black spot (CBS) is a disease caused by the Phyllosticta citricarpa fungus (Guignardia citricarpa Kiely at its cytomorphic phase) that causes qualitative and quantitative damages to citrus crops Qualitative damages caused by CBS can depreciate the fruit peels and make it impossible to export them to European Union countries, where this fungus is a quarantine pest (A1); quantitative damages due to early fruit drops reduce plant fruit yield


Dhanucop (Copper Oxychloride 50% WP) is a copper based broad spectrum fungicide which controls the fungal as well as bacterial diseases by its contact action. It also effectively controls the fungus resistant to other fungicides. Due to its fine particles, it sticks to the leaves and helps to restrict the growth of the fungus.

A fungicide that controls a wide range of fungal and bacterial diseases on fruit, vegetables and ornamentals, protecting the plant.

Uses/benefits of Copper Oxychloride

  • Can be used on fruit, vegetables and ornamentals
  • Controls leaf curl, leaf spots, blights, downy mildew and black spot
  • Easy to mix, makes up to 40-66L of spray

Mode of action

It is a broad-spectrum contact fungicide with protective action. Copper because of its strong bonding affinity to amino acids and carboxyl groups, reacts with protein and acts as an enzyme inhibitor in target organisms. Copper kills spores by combining with sulphahydral groups of certain enzymes. Spores actively accumulate copper and thus germination of spores is inhibited, even at lower concentrations.

Features of Copper Oxychloride

  • Dhanucop due to less solubility, gradually releases copper ions, thereby it controls the disease for a longer period.
  • Provides thickness to leaves and hence preferred by the farmers. Provides Copper nutrition to crop.
  • Very high Suspensibility and smallest particle size.
  • Ideal fungicide during hailstorms/ rains.
  • Being natural compound, safe to mammals.
