Can you please advise when best to use Liquid Copper as opposed to Copper Oxycholoride and vice versa.

Both the Yates Leaf Curl Copper Fungicide Spray and the liquid copper work by preventing the entry of the fungus into the plant. Both copper sprays can be used to control a number of fungal problems in the home garden. When looking at both labels the liquid copper is more specific in relation to controlling fungal problems on fruits such as lychees and nut trees such as macadamias. The liquid copper spray and the Yates Leaf Curl Copper Fungicide Spray will still control diseases on stonefruit, vegetables such as tomatoes, crucifers, brassicas and other vegetables and ornamentals in the home garden. Both products have a 1 day withholding period. It really come down to which type of spray you prefer to use. Once advantage of the liquid copper is that when combined with water, it creates an aquagel that spreads readily over the leaves and stems and sticks firmly into place.
