Copper Oxide 60% + Metalaxyl-M 6% WP
Copper (1) oxide
A widely used copper fungicide that is approved for use in many countries including at EU level. It has a low aqueous solubility and a low volatility. As a heavy metal, copper itself will not degrade in the environment. It is moderately toxic to mammals and most biodiversity.
Description: An inorganic-copper fungicide and insecticide also used as a mineral supplement for livestock
Example pests controlled: Various fungal pathogens including those causing mildews and leaf spots.
Example applications: Fruit including mango, avocado, grapes, kiwi, plums, olives; Nuts; Cocoa
Chemical structure:
General status:
Metalaxyl-M
Description: A fungicide used to control diseases caused by air- and soil-borne pathogens
Example pests controlled: Foliar and tuber blight; Downey mildews;Pseudoperonospora humuli; Phytophthora infestans ; Peronospora tabacina
Example applications: Potatoes; Tomatoes; Hops; Lettuce; Vegetables; Tobacco
