Copper Fungicide has been used for years as a means of keeping cannabis plants healthy. Its main purpose is to combat any diseases that are caused by bacteria and fungi. Key signs that your cannabis plants are suffering from either powdery mildew or downy mildew are white fuzzy patches on the leaves, this mold can completely take over your plants and damage them beyond repair if it isn’t treated quick enough.
This is where the Copper Fungicide comes in – thanks to this product from Bonide can help to treat this mold on outdoor marijuana plants. Simply dilute it down and then spray onto your plant before it gets to the flowering stage. Make sure you check the label directions carefully as with the wrong concentrate to water ratio it is possible to ‘burn’ your plants, especially if they are young. Also, what’s great about this product is that it won’t harm infects that benefit your plants such as ladybugs.
